Answers

Answer 1

The standard form of the equation of the ellipse satisfying the given conditions is `(x - 1)^2/81 + (y + 3)^2/16 = 1`.

The standard form of the equation of the ellipse satisfying the following conditions: Vertices of major axis are (1,6) and (1, -12) and the length of the minor axis is 8 is given by `x^2/a^2 + y^2/b^2 = 1`.

The center is (1, −3).The length of the major axis is the distance between the two vertices, which is 6 + 12 = 18.

Thus, 2a = 18 and a = 9.

The length of the minor axis is 8, so 2b = 8, and b = 4.

The center is the midpoint between the vertices: (1, 6) and (1, −12).Thus, (x − 1)2 + (y + 3)2/16 = 1 is the standard form of the equation of the ellipse.

Hence, the standard form of the equation of the ellipse satisfying the given conditions is `(x - 1)^2/81 + (y + 3)^2/16 = 1`.

To find the diameter of the hole that is drilled vertically through the center of the solid, we first need to calculate the volume of the solid and the volume of the removed portion of the solid and then subtract the removed portion of the solid from the volume of the solid to get the volume of the remaining solid. Finally, we can use the formula for the volume of a cylinder to find the diameter of the hole that is drilled vertically through the center of the remaining solid. Let's solve this problem step by step below:  To find the volume of the solid, we can use the triple integral given below: To find the volume of the removed portion of the solid, we need to calculate one-tenth of the volume of the solid.

Therefore, the volume of the removed portion of the solid is approximately 40.5825.Step 3: To find the volume of the remaining solid, we can subtract the volume of the removed portion of the solid from the volume of the solid.

measure of angle C in degrees and rounded to 1 decimal place.

Answers

Answer: The measure of angle C in degrees and rounded to 1 decimal place is approximately 131.8.

Explanation: In triangle ABC, a = 6, b = 9 & c = 11. To find the measure of angle C in degrees and rounded to 1 decimal place, we can use the Law of Cosines. The Law of Cosines states that for any triangle ABC:

[tex]$$c^2 = a^2 + b^2 - 2ab \cos(C)$$\\Rearranging the equation:$$\cos(C) = \frac{a^2 + b^2 - c^2}{2ab}$$[/tex]

Substituting the given values :

[tex]$$\cos(C) = \frac{6^2 + 9^2 - 11^2}{2(6)(9)}$$\\Solving for cos(C): $$\cos(C) = \frac{-2}{3}$$[/tex]

Now, using the inverse cosine function, we can find the value of C in degrees:

[tex]$$C = \cos^{-1}\left(\frac{-2}{3}\right)$$\\ Rounding to 1 decimal place:\\$$C \approx 131.8^\circ$$[/tex]

Therefore, the measure of angle C in degrees and rounded to 1 decimal place is approximately 131.8.

Find the volume below the cone z = 6√x² + y² and above the disk r = 6 cos 0. Sketch the region. Hint: On your first attempt you might get zero. Think about why and then tweak your integral.

Answers

The volume below the cone z = 6√x² + y² and above the disk r = 6 cos 0 is 54π ln(1 + √2). The given function is a cone z = 6√x² + y² and the given disk is r = 6 cos 0. The region of interest is a circular disk centered at the origin with a radius of 6.

This is because the cone and the disk intersect each other along a circular plane at a distance of 6 from the origin. We must determine the volume of this region of interest.  Below is the sketch of the region:The cone z = 6√x² + y² intersects the xy-plane along the circle x² + y² = 9 (from r = 6 cos θ) where z = 0. This is the base of the region of interest. The cone intersects the xy-plane again along the circle x² + y² = 36 where z = 6. This is the top of the region of interest. Therefore, we must integrate the function z = 6√x² + y² over the region of the circle x² + y² ≤ 9.

But instead of integrating the given function over the circular disk, we will integrate the function over a half-cylinder of radius 6, which is identical to the circular disk. This is done so that we can make use of cylindrical coordinates, which will make our computations easier.The height of the half-cylinder is 6 and its radius is 6. Therefore, the volume of the half-cylinder is:V = πr²h/2where r = 6 and h = 6. Therefore, V = 216π. This is the volume of the region of interest.We have to tweak our integral to find the volume below the cone z = 6√x² + y² and above the disk r = 6 cos 0. We can write the equation of the cone as z² = 36x² + 36y².

Squaring the equation of the cone, we get:z² = 36x² + 36y² ⇒ z⁴ = 1296(x² + y²)³ Now, in cylindrical coordinates, we have:x = r cos θ, y = r sin θ, and z = z. Substituting these values, we get:r²z⁴ = 1296r⁴ ⇒ z² = 36/√(1 + (r/9)²)Now, we integrate z over the region of interest, which is the circular disk of radius 6. Therefore, the integral becomes:I = ∫∫ z dAwhere the region of integration is given by x² + y² ≤ 9. We can use cylindrical coordinates to rewrite the integral as:I = ∫[0, 2π] ∫[0, 6] zr dz dr dθ We can find the limits of integration for z by using the equation of the cone we found above.

Therefore, our integral becomes:I = ∫[0, 2π] ∫[0, 6] 6/√(1 + (r/9)²) r dz dr dθ Now, we substitute u = r/9 and simplify the integral. Therefore, we get:I = 54π ∫[0, 2π] ∫[0, 2/3] 1/√(1 + u²) du dθ This integral can be evaluated using a trig substitution. Therefore, we substitute u = tan θ and du = sec² θ dθ. Therefore, we get:I = 54π ∫[0, π/2] ∫[0, 1] sec θ dθ duI = 54π ln(1 + √2)

Therefore, the volume below the cone z = 6√x² + y² and above the disk r = 6 cos 0 is 54π ln(1 + √2).

Therefore, the value of dt/dy at x = -4, where y = 2x² - 4 and dx/dt = -4 is -1/4.

The given question is about solving the following problems.

1) Find the value of lim x → ∞ [g(x)]² - 1/[f(x)]² - 5f(x) + 4

2) Use tangent line approximation to find the monthly salary of a dock worker in 2013 when t = 32 given the data from 1980 to 2012.1)

To find the limit of the function g(x), we can write g(x) as g(x) = f(x) + 1;

f(x) as lim x → ∞

f(x) = ∞ and

g'(x) = f'(x)

⇒ lim x → ∞

g'(x) = lim x → ∞

f'(x) = 10

To solve the given problem, we will apply the L'Hospital's Rule as shown below.

g(x) = f(x) + 1

=> [g(x)]² - 1

= f²(x) + 2f(x) + 1 - 1

= f²(x) + 2f(x)f(x)

= ∞; [f(x)]² - 5f(x) + 4

= ∞

∴ lim x → ∞ [g(x)]² - 1/[f(x)]² - 5f(x) + 4

= lim x → ∞ [f²(x) + 2f(x)]/[f(x)]²

= lim x → ∞ [f(x) + 2]/f(x)

= 1 + lim x → ∞ 2/f(x) = 1 + 2/∞

To find the value of limit, lim x → ∞ [g(x)]² - 1/[f(x)]² - 5f(x) + 4

= 1.

To find the monthly salary of the dock worker in 2013, we need to find the value of S(32) using the given function as shown below.

S(t) = 0.181t³ - 8.25t² - 102.3t + 991

S(32) = 0.181(32)³ - 8.25(32)² - 102.3(32) + 991

= 649.088

The tangent line approximation is given as shown below.

f(t) = 0.181t³ - 8.25t² - 102.3t + 991

When t = 32,f(32)

= 0.181(32)³ - 8.25(32)² - 102.3(32) + 991

= 649.088f'(t)

= 0.543t² - 16.5t - 102.3

When t = 32,f'(32)

= 0.543(32)² - 16.5(32) - 102.3

= 149.376

∴ The tangent line is given by;

y - 649.088 = 149.376(t - 32)

The monthly salary of the dock worker in 2013 is predicted by substituting the value of t = 33 in the above equation as shown below.

y - 649.088 = 149.376(33 - 32)

=> y = 798.464

Therefore, the predicted monthly salary of the dock worker in 2013 is $798.46.

The stability margin of a closed loop control system non of the above O increases if the change in the set point is a ramp instead of .a step increases as the magnitude of the step change in set .point increases increases as the magnitude of the step change in set point decreases

Answers

The stability margin of a closed-loop control system increases as the magnitude of the step change in the set point decreases.

The stability margin of a closed-loop control system refers to the ability of the system to remain stable despite disturbances or changes in the input. When the magnitude of the step change in the set point decreases, it means that the change is smaller. This smaller change results in less disruption to the system and allows the control system to respond more effectively and maintain stability. The stability margin increases because the system has more room to adjust and can compensate for smaller changes in the set point. As a result, the system becomes more robust and less prone to instability. Therefore, as the magnitude of the step change in the set point decreases, the stability margin of the closed-loop control system increases.

Answers

The function f(x) = 2x² - 4x is given. We have to calculate the average rate of change of f(x) on the interval [1, 1 + h].Solution: Given function is f(x) = 2x² - 4x.The interval is [1, 1 + h].Therefore, the change in x = (1 + h) - 1 = h.

We know that the average rate of change of the function f(x) on the interval [a, b] is (f(b) - f(a))/(b - a).Therefore, the average rate of change of the function f(x) on the interval [1, 1 + h] is: {(2(1+h)² - 4(1+h)) - (2(1)² - 4(1))} / {(1+h) - 1}= {(2(1+h)² - 4(1+h)) - (2(1)² - 4(1))} / hNow, we will simplify the above expression.{(2(1+h)² - 4(1+h)) - (2(1)² - 4(1))} / h= {(2(1+2h+h²) - 4-4h) - (2 - 4)} / h= {(2h² + 4h) - 2} / h= (2h² + 4h - 2) / h= 2h + 4 - (2 / h)Therefore, the average rate of change of f(x) on the interval [1, 1 + h] is 2h + 4 - (2 / h).Hence, the correct option is (C) 2h + 4 - (2 / h).

Now, let's calculate g(y).Given, Hannah started with 10 credits and to earn her degree, she had to acculumate 180 credits.Therefore, to calculate the number of credits that Hannah still needed to earn after attending UWB for y years, we have to subtract the credits earned by Hannah from 180. This can be represented as:C = 180 - (10 + y * 30)where C = g(y).Now, let's calculate g(0).

To calculate g(0), we have to substitute y = 0 in C = 180 - (10 + y * 30).Therefore, g(0) = 180 - (10 + 0 * 30) = 170.C = 170 (credits)Hence, g(0) = 170.To calculate g(4), we have to substitute y = 4 in C = 180 - (10 + y * 30).Therefore, g(4) = 180 - (10 + 4 * 30) = 30.C = 30 (credits)Hence, g(4) = 30.To calculate the average rate of change in C = g(y) from y = 0 to y = 4, we have to use the formula:(g(4) - g(0))/(4 - 0)Therefore, the average rate of change in C = g(y) from y = 0 to y = 4 is:(g(4) - g(0))/(4 - 0)= (30 - 170) / 4= -140/4= -35.C = -35 (credits per year)

cos(20) = 2 cos² 0 -1cos(30)

First, we'll prove the first expression cos(20) = 2 cos² 0 -1:

LHS (Left Hand Side)=cos(20)RHS (Right Hand Side)=2 cos² 0 -1 = 2 cos² 0 - sin² 0

(using the trigonometric identity: sin² θ + cos² θ = 1)

RHS=cos² 0 + cos² 0 - sin² 0

RHS=cos² 0 + sin² 90 - sin² 0

(Using the trigonometric identity: cos² θ + sin² θ = 1)

RHS=cos² 0 + cos² 90

= 1(cos 90 = 0, sin 90 = 1)

Therefore, LHS = RHS,

so cos(20) = 2 cos² 0 -1 is proved

Now, we'll prove the second expression cos(30) = 4 cos³ 0 - 3 cos 0:

LHS (Left Hand Side)=cos(30)RHS (Right Hand Side)

=4 cos³ 0 - 3 cos 0

We know,cos 3θ = 4 cos³ θ - 3 cos θ

Using this formula, we can write:LHS=cos(3 * 10)

= cos(30)RHS

=4 cos³ 0 - 3 cos 0

Therefore, LHS = RHS, so cos(30) = 4 cos³ 0 - 3 cos 0 is also proved.

Substituting x = 7, µ = 5.1, and σ = 0.8 into the formula, we get:

z = (7 - 5.1) / 0.8 = 2.375

Next, we can use a standard normal distribution table to find the probability of a z-score greater than 2.375. The probability is approximately 0.0087.

In summary, using the normal distribution, we can estimate that the probability of a student taking longer than 7 years to graduate is approximately 0.0087.

The distance from home plate to dead center field in Sun Devil Stadium is 406 feet. A baseball diamond is a square with a distance from home plate to first base of 90 feet. How far is it from first base to dead center field? A) 383.5 feet B) 331.1 feet C) 473.9 feet D) 348.2 feet

Answers

The distance from first base to dead center field is approximately 396.09 feet, which does not match exactly with any of the given answer choices.

To find the distance from first base to dead center field, we can use the Pythagorean theorem. Since a baseball diamond is a square, the distance from home plate to first base is the same as the distance from first base to second base, third base to home plate, and second base to third base. Let's denote the distance from first base to dead center field as d.

According to the Pythagorean theorem, in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the distance from home plate to dead center field (406 feet) represents the hypotenuse, and the distance from home plate to first base (90 feet) represents one of the other sides.

So, we can set up the equation:

d^2 = 406^2 - 90^2

d^2 = 164836 - 8100

d^2 = 156736

d ≈ √156736

d ≈ 396.09

The approximate distance from first base to dead center field is 396.09 feet.

Among the answer choices, the closest option is D) 348.2 feet. However, this is not an exact match for the calculated distance. It is possible that the answer choices provided are rounded values or that there is an error in the options provided.

Answers

With these values, the gradient vector of f at (2,3) can be found by putting x=2 and y=3 in the formula of gradient vector which is:  [-12, -6]

If f(x,y)

fx(2,3) = fy(2,3) = 36 - 6x² - y²,

then the function of f can be written as

f(x,y) = 36 - 6x² - y².

Now, f(2,3) means we need to find the value of f when x=2 and y=3.

Therefore,

f(2,3) = 36 - 6(2)² - 3²= 36 - 6(4) - 9 = 3f(x,y)

and f(x,y) are given by the formula

f(x,y) = 36 - 6x² - y².

As per the question,

fx(2,3) = fy(2,3) = 36 - 6x² - y²fx(2,3)

means we need to find the partial derivative of f with respect to x when x=2 and y=3.

So, f,x(2,3) = -12fy(2,3) means we need to find the partial derivative of f with respect to y when x=2 and y=3.

Therefore, f,y(2,3) = -6

What is the total surplus? f. Draw and label a graph for this market. Make sure the values for questions (a)-(e) are placed appropriately on the graph.

Answers

a. The market equilibrium price can be found by setting the quantity demanded equal to the quantity supplied. In this case, we have Pd = Ps, so we can set -10Qd + 80 = 2Qs + 20. Solving for Qs, we get Qs = (60 + 10Qd)/2.

b. To find the market equilibrium quantity, we substitute the value of Qs into the equation for Ps: Ps = 2Qs + 20. Plugging in the value of Qs, we get Ps = (60 + 10Qd)/2 + 20. Simplifying this equation, we find Ps = (30 + 5Qd) + 20, which simplifies further to Ps = 50 + 5Qd.

c. Consumer surplus represents the difference between the price consumers are willing to pay and the market equilibrium price. To calculate the consumer surplus, we need to find the area of the triangle above the market equilibrium quantity and below the demand curve. In this case, the demand curve equation is Pd = -10Qd + 80.

d. Producer surplus represents the difference between the market equilibrium price and the price producers are willing to sell at. To calculate the producer surplus, we need to find the area of the triangle below the market equilibrium quantity and above the supply curve. In this case, the supply curve equation is Ps = 2Qs + 20.

e. Total surplus is the sum of the consumer surplus and the producer surplus.

f. To graph the market, we can plot the demand and supply curves on a graph with price on the y-axis and quantity on the x-axis. We can label the equilibrium price and quantity as the point where the demand and supply curves intersect. The consumer surplus and producer surplus can be represented by shaded areas on the graph.

The specific values for the market equilibrium price, quantity, consumer surplus, producer surplus, and total surplus cannot be determined without additional information or values for Qd.

A satellite flies 58404 58404 miles in 9.42 9.42 hours. How many miles has it flown in 23.45 23.45 hours?

Answers

To solve this problem, we can use the formula:

distance = rate x time

First, we need to find the rate of the satellite:

rate = distance / time

rate = 58404 miles / 9.42 hours

rate = 6192.8 miles/hour

Now we can use this rate to find the distance the satellite flies in 23.45 hours:

distance = rate x time

distance = 6192.8 miles/hour x 23.45 hours

distance = 145276.16 miles

Therefore, the satellite has flown approximately 145276.16 miles in 23.45 hours.

Answers

The approximate (x,y) coordinates of the point are (-0.6536, -0.7568) to 4 decimal places.

To compute the (x,y) coordinates of a point at an angle of 4 radians on a circle of radius 3 centered at the origin, we can use the following steps:

Recall that the equation for a circle centered at the origin is x^2 + y^2 = r^2, where r is the radius.

Plug in the given values to get x^2 + y^2 = 3^2 = 9.

Use the angle and the trigonometric functions cosine and sine to find the (x,y) coordinates. Since the angle is measured from the positive x-axis counterclockwise, we can use cosine to find the x-coordinate and sine to find the y-coordinate.

The cosine of 4 radians is cos(4) = -0.6536 (rounded to 4 decimal places).

The sine of 4 radians is sin(4) = -0.7568 (rounded to 4 decimal places).

Substitute these values into the equation for the circle to find the x and y coordinates:

x^2 + y^2 = 9

(-0.6536)^2 + (-0.7568)^2 = x^2 + y^2

0.4273 + 0.5735 = x^2 + y^2

1.0008 ≈ x^2 + y^2

Taking the square root of both sides yields sqrt(1.0008) ≈ sqrt(x^2 + y^2)

Answer:

y - 3 = -4(x + 1).

Step-by-step explanation:

First,  calculate the slope (m) using the formula:

y - y1 = m(x - x1),

m = (y2 - y1) / (x2 - x1),

where (x1, y1) = (-1, 3)

(x2, y2) = (2, -9):

m = (-9 - 3) / (2 - (-1))

Answers

The required maximum volume of the box inscribed in the tetrahedron can be obtained as follows. The required maximum volume of the box inscribed in the tetrahedron is 1/648 cubic units.

1. Write the equation of the plane x + 4y + z = 1 in terms of z.z = 1 - x - 4y

2. For each point (x, y, z) in the tetrahedron, determine the range of values that the length of the side of the box parallel to the z-axis can take.

3. Express the volume of the box in terms of x and y.4. Find the maximum volume of the box by maximizing the expression from step 3.

1. Writing the equation of the plane x + 4y + z = 1 in terms of z, we have: z = 1 - x - 4y.

2. For each point (x, y, z) in the tetrahedron, the range of values that the length of the side of the box parallel to the z-axis can take is given by the minimum of the values of z, 1 - x, 1 - 4y.

Therefore, the length of the side of the box parallel to the z-axis can take a maximum value of min(1 - x, 1 - 4y, z). Let's denote this maximum value by l. Thus, we have l = min(1 - x, 1 - 4y, z) or l = min(1 - x, 1 - 4y, 1 - x - 4y).

3. The volume of the box can be expressed in terms of x, y, and z as V = l(x - 2l)(y - 2l).

Substituting for l, we get V = min(1 - x, 1 - 4y, z)(x - 2min(1 - x, 1 - 4y, z))(y - 2min(1 - x, 1 - 4y, z)).

4. To find the maximum volume of the box, we need to maximize the expression for V.

We can do this by differentiating V with respect to x and y and setting the resulting expressions to zero. Using the chain rule, we obtain

:V'x = -(2min(1 - x, 1 - 4y, z) - x)(y - 2min(1 - x, 1 - 4y, z))V'y = -(2min(1 - x, 1 - 4y, z) - y)(x - 2min(1 - x, 1 - 4y, z))

Setting V'x and V'y to zero, we get:2min(1 - x, 1 - 4y, z) = x and 2min(1 - x, 1 - 4y, z) = y.

Since min(1 - x, 1 - 4y, z) must be positive, we can solve the above equations to obtain the values of x and y at which V is a maximum. These are x = 2/3 and y = 1/6, respectively.

Using the equation for l, we get l = min(1 - 2/3, 1 - 4(1/6), 1/3) = 1/6. Therefore, the maximum volume of the box is V = (1/6)(2/3 - 2/3)(1/6 - 2/6) = 1/648 cubic units.

Answers

We are given the values of sine and cosine for two angles, θ and φ, and we need to evaluate the expression sin(θ + φ). θ is in Quadrant I, and its sine is 8/17. Sin(θ + φ) evaluates to 22√5/85.

φ is in Quadrant II, and its cosine is -√5/5. To evaluate sin(θ + φ), we can use the trigonometric identity sin(θ + φ) = sin θ cos φ + cos θ sin φ. By substituting the given values, we can find the result.

Using the given values, we have sin(θ) = 8/17 and cos(φ) = -√5/5. To evaluate sin(θ + φ), we can use the trigonometric identity:

sin(θ + φ) = sin θ cos φ + cos θ sin φ.

Substituting the given values, we get:

sin(θ + φ) = (8/17) * (-√5/5) + (cos(θ) * sin(φ)).

Since θ is in Quadrant I, its cosine is positive, and sin(φ) is also positive because φ is in Quadrant II. We can calculate cos(θ) as follows:

cos(θ) = √(1 - sin²(θ)) = √(1 - (8/17)²) = √(1 - 64/289) = √(225/289) = 15/17.

Substituting the values, we have:

sin(θ + φ) = (8/17) * (-√5/5) + (15/17) * (sin(φ)).

Now we need to find sin(φ). Since cos(φ) = -√5/5, we can use the Pythagorean identity sin²(φ) = 1 - cos²(φ) to find sin(φ):

sin(φ) = √(1 - cos²(φ)) = √(1 - (-√5/5)²) = √(1 - 5/25) = √(20/25) = √(4/5) = 2/√5 = 2√5/5.

Substituting the value of sin(φ), we get:

sin(θ + φ) = (8/17) * (-√5/5) + (15/17) * (2√5/5).

Simplifying further:

sin(θ + φ) = (-8√5/85) + (30√5/85) = 22√5/85.

Therefore, sin(θ + φ) evaluates to 22√5/85.

(a) Find the standard error of the distribution of differences in sample proportions, p^A−p^Bp^A-p^B.
Round your answer for the standard error to three decimal places.

Answers

To find the standard error of the distribution of differences in sample proportions, p^A - p^B, where p^A and p^B are the sample proportions from populations A and B respectively, we can use the formula: SE(p^A - p^B) = sqrt((p^A(1 - p^A)/nA) + (p^B(1 - p^B)/nB)), where nA and nB are the sample sizes from populations A and B respectively. Given that the sample size for population A is 80 with a proportion of 0.47, and the sample size for population B is 66 with a proportion of 0.19, we can substitute these values into the formula to calculate the standard error.

The standard error of the distribution of differences in sample proportions, SE(p^A - p^B), measures the variability or uncertainty in the estimated difference between the sample proportions of two populations.

To calculate the standard error, we use the formula: SE(p^A - p^B) = sqrt((p^A(1 - p^A)/nA) + (p^B(1 - p^B)/nB)), where p^A and p^B are the sample proportions from populations A and B respectively, and nA and nB are the sample sizes from populations A and B respectively.

In this case, the sample size for population A is 80, and the proportion is 0.47. Thus, we substitute nA = 80 and p^A = 0.47 into the formula. Similarly, for population B, the sample size is 66, and the proportion is 0.19, so we substitute nB = 66 and p^B = 0.19 into the formula.

By substituting the values and performing the calculations, we find the standard error of the distribution of differences in sample proportions to three decimal places.

F = first

O = outside

I = inside

L = last

Now multiply.

The first terms are c and c.

[tex]\sf{(c-5)(c-6)}[/tex]

[tex]\sf{c^2}[/tex]

Next, we multiply c times -6

[tex]\sf{-6c}[/tex]

Then, we multiply -5 times c

[tex]\sf{-5c}[/tex]

Finally, we multiply -5 times -6

[tex]\sf{-30}[/tex]

Put the terms together

[tex]\sf{c^2-6c-5c+30}[/tex]

Combine like terms

[tex]\sf{c^2-11c+30}[/tex]

An investor is considering starting a new business whilst working with a local government as Accountant. The company would require GHS 500,000 of assets, and it would be financed entirely with common stock. The investor will go forward only if he thinks the firm can provide a 15.0 percent return on the invested capital, which means that the firm must have an ROE of 15.0 percent. After operating the business for 5 years, he realized the importance of debt and tax deductibility that comes with it. He then decided to alter the capital structure whilst expanding the size of the business. His total assets came to GHS 647m financed as follows: Market value of Debt= GHS 194m with 11% Market value of Equity= GHS 453m with expected return of 17% Just as he was about obtaining an additional loan in 2020, Covid-19 and its containment measures (such as social distancing, stay at home etc) affected his business which operated more with human interaction. The three-week partial lockdown has affected the going concern of his business. Government has set up the Coronavirus Alleviation Programme (CAP) with seed money of GHS 1 billion. An amount of GHS 600 million of this money is to be disbursed to vulnerable firms and GHS 400m to vulnerable households. The government also announced free water for three months (April to June 2020) to all citizens consistent with the health protocols of washing hands as often as possible under running water though one-third of the African population cannot wash their hands simply because of lack of running water. For the three months, electricity has been zero-rated for lifeline consumers (from 0-50 kilowatt-hours a month consumption) whilst all other categories of consumers enjoy a 50% subsidy. Given the enhanced exposure of frontline workers as a result of the pandemic, the government also offered tax exemptions amounting to 50% of their basic salary for the three months translating to fiscal loses of GHS 288.6m including additional allowances for frontline health personnel covering March, April, May, and June for the year 2020 (amounting to GHS 51 million). But the Accountant has complained for his exclusion from the list of beneficiaries. Bank of Ghana (BoG) also responded by reducing the policy rate by 150 basis points as well as reducing the Primary Reserve Requirement from 10% to 8%. His bank loan is indexed to the primary reserve requirement and varies accordingly.
