In the following figure, assume that a, b, and c = 5, e = 12, and d = 13. What is the area of this complex figure? Note that the bottom triangle is a right triangle. The height of the equilateral triangle is 4.33 units.

Answer:

The formula for calculating the future value (VF) of a periodic sum of money is:

VF = P * [(1 + r) n - 1] / r

where:

   VF is the future value (the total amount in the savings account)

   P is the periodic amount (monthly deposit)

   r is the periodic interest rate (annual interest rate divided by the number of periods in the year)

   n is the total number of periods (months)

In this case, P = $110, r = 3% / 12 = 0.03/ 12 = 0.0025 (monthly interest rate) and n = 3 * 12 = 36 (three years equivalent to 36 months).

Using these values in the formula, we can calculate the future value (VF):

VF = 110 * [(1 + 0.0025) 36 - 1] / 0.0025

Now let’s calculate this:

VF = 110 * [(1.0025) 36 - 1] / 0.0025

110 * (1.0965726572 - 1) / 0.0025

110 * 0.0965726572 / 0.0025

So Jackson will have about $4,239.52 in his savings account after three years, assuming he doesn’t make any withdrawals during that period.

Answer:

The solutions to the quadratic equation 0 = -3x² - 4x + 5 in simplest radical form are x = (-2 + √19) / 3 and x = (-2 - √19) / 3.

To find the solutions to the quadratic equation 0 = -3x² - 4x + 5, we can use the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a).

Comparing the equation to the standard quadratic form ax² + bx + c = 0, we have a = -3, b = -4, and c = 5.

Plugging these values into the quadratic formula, we get:

x = (-(-4) ± √((-4)² - 4(-3)(5))) / (2(-3))

= (4 ± √(16 + 60)) / (-6)

= (4 ± √76) / (-6)

= (4 ± 2√19) / (-6)

= -2/3 ± (1/3)√19

Therefore, the solutions to the quadratic equation are:

x = -2/3 + (1/3)√19 and x = -2/3 - (1/3)√19

In simplest radical form, the solutions are:

x = (-2 + √19) / 3 and x = (-2 - √19) / 3.

These expressions cannot be further simplified since the square root of 19 is not a perfect square.

a. The open interval on which the function is increasing is [-2/3, 0].

The open intervals on which the function is decreasing are [-∞, -2/3] and [0, -∞].

b. The function's has a local maximum at (0, 0) and a local minimum at (-2/3, -4/27).

For any given function, y = f(x), if the output value (range or y-value) is decreasing when the input value (domain or x-value) is increased, then, the function is generally referred to as a decreasing function.

By critically observing the graph of the given function, we can reasonably infer and logically deduce that it is decreasing over the following open intervals:

increasing = [-2/3, 0].

decreasing = [-∞, -2/3] and [0, -∞].

Part b.

The local minimum of a graph is the point on the graph of a function where it changes from a decreasing function to an increasing function, which is given by this ordered pair (-2/3, -4/27);

h(x) = -x³ - x²

h'(x) = -3x² - 2x

0 = -3x² - 2x

3x² = -2x

3x = -2

x = -2/3

Answer:

y=2x-6

Step-by-step explanation:

y+4=-2(x-1)

Since the slope intercept form is in the form of:

y=mx+c

Making above equation in this form.

y+4=-2(x-1)

opening bracket

y+4=2x-2

subtracting both side by 4.

y+4-4=2x-2-4

y=2x-6

This equation is the slope intercept form.

The x-coordinate of the vertex is given by h = -2 and the equation of the axis of symmetry is x = -2.

Given function is H(x) = -(x + 2)² + 8.

The axis of symmetry of a quadratic function y = ax² + bx + c is defined by x = -b/2a.

So, let's solve the problem as follows:

To find the axis of symmetry, we need to convert the given function into standard form y = a(x - h)² + k.

We can do this by completing the square.

For that, we have

H(x) = -(x + 2)² + 8H(x)

= -1(x² + 4x + 4) + 8H(x)

= -1(x + 2)² + 8

The standard form is y = a(x - h)² + k, so the given function is y = -1(x + 2)² + 8.

The vertex form of a quadratic equation is y = a(x - h)² + k

Where(h, k) is the vertex.

The vertex form of the given function H(x) = -(x + 2)² + 8 can be calculated as follows:  

y = a(x - h)² + k

The vertex form is y = a(x - h)² + k.

Where the vertex form of the given function is:

y = -1(x + 2)² + 8.

Since the vertex form is y = a(x - h)² + k the vertex form of the given function is y = a(x + 2)² + 8 and (h, k) = (-2, 8).

Vertex is given by h = -2.

Axis of symmetry is x = -2.

The equation of the line perpendicular to the line with a slope of 1/13 and passing through the point (-1, 3) is y = -13x - 10.

To find the equation of a line perpendicular to a line with a slope of 1/13 and passing through the point (-1, 3), we need to determine the slope of the perpendicular line.

The slope of a line perpendicular to another line can be found by taking the negative reciprocal of the given slope. The negative reciprocal of 1/13 is -13/1, or simply -13.

Now that we have the slope (-13) and a point (-1, 3) that the line passes through, we can use the point-slope form of a linear equation to find the equation of the perpendicular line.

The point-slope form is given by:

y - y₁ = m(x - x₁)

where (x₁, y₁) is the given point and m is the slope.

Substituting the values (-1, 3) and -13 into the point-slope form, we get:

y - 3 = -13(x - (-1))

Simplifying:

y - 3 = -13(x + 1)

Expanding the equation:

y - 3 = -13x - 13

To convert the equation to slope-intercept form (y = mx + b), we can isolate y:

y = -13x - 13 + 3

y = -13x - 10

Therefore, the equation of the line perpendicular to the line with a slope of 1/13 and passing through the point (-1, 3) is y = -13x - 10.

4.1 To convert the mass of the self-raising flour to kg, we can divide the mass by 1000, since there are 1000 grams in a kilogram:

2 500 g ÷ 1000 = 2.5 kg

So the mass of the self-raising flour is 2.5 kg.

4.2 To determine the number of cups of bran flour needed to bake 400 g of rusks, we can use a proportion:

800 g of rusks requires 10 cups of bran flour

400 g of rusks requires x cups of bran flour

We can set up the proportion as:

800 g ÷ 10 cups = 400 g ÷ x cups

Cross-multiplying, we get:

800 g x cups = 10 cups x 400 g

Simplifying, we get:

x = 5 cups

So 5 cups of bran flour are needed to bake 400 g of rusks.

4.3 To write the ratio of raisins to butter in simplified form, we can divide both quantities by their greatest common factor. The greatest common factor of 200 g and 1 000 g is 200 g, so we can divide both by 200 g:

200 g ÷ 200 g = 1

1 000 g ÷ 200 g = 5

So the simplified ratio of raisins to butter is 1:5.

Mr. Marshal spent 1/4 of his salary on miscellaneous expenses and $1,680 on rental; therefore, he spent 1/36 of his entire salary on the trip.

To find the fraction of money spent on miscellaneous, we need to calculate the sum of the fractions spent on rental, food, and bank and subtract it from 1.

Rental: 1/5

Food: 1/10

Bank: 1/4

To find the fraction spent on miscellaneous:

Fraction spent on miscellaneous = 1 - (Rental + Food + Bank)

Rental + Food + Bank = 1/5 + 1/10 + 1/4 = (8 + 4 + 5)/40 = 17/40

Fraction spent on miscellaneous = 1 - 17/40 = 23/40

So, Mr. Marshal spent 23/40 of his salary on miscellaneous.

To find the amount spent on rental, we multiply the fraction spent on rental by his salary:

Amount spent on rental = (1/5) [tex]\times[/tex] $8,400 = $1,680

Therefore, Mr. Marshal spent $1,680 on rental.

If Mr. Marshal spent 4/9 of the miscellaneous amount on a trip, we need to calculate the fraction of his entire salary spent on the trip.

Fraction spent on the trip = (4/9) [tex]\times[/tex] (23/40) = 92/360 = 23/90

Case 1: SE = s / √500

Case 2: SE = s / √5,000

Case 3: SE = s / √50,000

To find the standard error of the mean in each of the given cases, we can use the formula:

Standard Error (SE) = population standard deviation / square root of sample size

However, since the population standard deviation is not provided, we'll need to use an estimated value. We'll assume the population standard deviation is unknown and use the sample standard deviation as an estimate.

Given that the sample size is 44 and the population mean (μ) is 8, we'll calculate the standard deviation for each case:

Case 1: Sample size (n) = 500

The sample size (500) is larger than 5% of the population (44), so we can assume it's a large enough sample. In this case, we'll use the standard formula for the standard error of the mean without the finite population correction factor:

SE = sample standard deviation / square root of sample size

= s / √n

Case 2: Sample size (n) = 5,000

Similar to Case 1, the sample size (5,000) is larger than 5% of the population (44), so we'll use the standard formula without the finite population correction factor:

SE = s / √n

Case 3: Sample size (n) = 50,000

In this case, the sample size (50,000) is much larger than the population size (44), which means we have a large enough sample. Therefore, we'll also use the standard formula without the finite population correction factor:

SE = s / √n

Answer:

y = (2x + 5)(2x + 3)

Step-by-step explanation:

y = 4x² + 16x + 15

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 4 × 15 = 60 and sum = + 16

the factors are + 10 and + 6

use these factors to split the x- term

y = 4x² + 10x + 6x + 15 ( factor the first/second and third/fourth terms )

y = 2x(2x + 5) + 3(2x + 5) ← factor out (2x + 5) from each term

y = (2x + 5)(2x + 3)

since multiplication is commutative , then could be

y = (2x + 3)(2x + 5)

Answer:

Samuel = 21 orders

Nicole = 31 orders

Miguel = 63 orders

Step-by-step explanation:

Let N represent Nicole's orders, M represents Miguel's orders, and S represent Samuel's orders.

We know that the sum of their tree orders equals 115 as

N + M + S = 115

Since Miguel served 3 times as many orders as Samuel, we know that

M = 3S.

Since Nicole served 10 more orders than Samuel, we know that

N = S + 10

Samuel's Orders:

Now we can plug in 3S for M and S + 10 for N to find S, the number of Samuel's orders:

S + 10 + 3S + S = 115

5S + 10 = 115

5S = 105

S = 21

Thus, Samuel served 21 orders.

Nicole's Orders:

Now we can plug in 21 for S in N = S + 10 to determine how many orders Nicole served:

N = 21 + 10

N = 31

Thus, Nicole served 31 orders.

Miguel's Orders:

Now we plug in 19 for S in M  = 3S to determine how many orders Miguel served:

M = 3(21)

M = 63

Thus, Miguel served 63 orders.
