There is a straight road leading from the town of Timpson to Ashburn 60 miles east and 12 miles north. Partway down the road, it junctions with a second road, perpendicular to the first, leading to the town of Garrison, which is located 22 miles directly east of the town of Timpson.

Below is a diagram that models this problem using lines. Which of the following could be the equation for the line representing the second road leading from the junction to Garrison?

Answer:

1. Distribute the 9

2. Add 9 to both sides

3. Divide both sides by 27

4. Write the fraction in lowest terms

Step-by-step explanation:

Generally for these problems we would first distribute the 9 and that is indeed going to be the first step in this equation, although one thing to note is it's really not necessary, since you could divide both sides by 9, and 0/9 is still 0, so it kind of simplifies the problem.

From that first step we would get:

[tex]27x-9=0[/tex]

From here we want to isolate the "x" variable, which we want to achieve by removing any constants on it's side, in this case -9, and then remove any coefficients in this case 27. We usually first start by removing any constants on the variables side which we can achieve by subtracting or adding a value, depending on the sign. The important thing to note is we want to do the inverse operation, essentially what cancels it out. So to cancel out minus 9 we simply add 9 to both sides to cancel out the minus 9 and to maintain equality.

[tex]27x=9[/tex]

Now from here we want to remove coefficients which we do by dividing, since the coefficient is simply multiplying, so the inverse is division. In this case we want to divide by 27, to cancel out the multiplication of 27.

[tex]x=\frac{9}{27}[/tex]

From here we can divide both the numerator and denominator by 9 to simplify the fraction.

[tex]x=\frac{1}{3}[/tex]

Both lines are parallel to each other, so it has no any intersection point.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The system of equation is,

⇒ 8x +10y =14   .. (i)

⇒ 4x + 5y = 4   .. (ii)

Now, By multiply by 2 in equation (ii), we get;

⇒ 2 (4x + 5y) = 4 × 2

⇒ 8x + 10y = 8  .. (iii)

Hence, By equation (i) and (iii), we get;

The both equations are parallel to each other and it has no solution.

Hence, It can never intersect each other at any point.

Answer: To the nearest dollar,  you should invest $84,639

Step-by-step explanation:

First, we need to calculate the number of compounding periods in a year.

For the first 18 months, the compounding period is monthly, so there are 18 x 12 = 216 compounding periods

For the next 6 months, the compounding period is quarterly, so there are 6 x 4 = 24 compounding periods

For the last 12 months, the compounding period is semi-annual, so there are 12 x 2 = 24 compounding periods

The total number of compounding periods is 216 + 24 + 24 = 264

Next, we need to calculate the effective annual interest rate for the entire 3-year period.

The effective annual interest rate is (1 + (8%/216))^216 x (1 + (1.5%/24))^24 x (1 + (2%/24))^24 - 1

Now we can calculate the principal amount (P) required to achieve the desired maturity value (F) using the formula:

P = F / (1 + r)^n

where F is the maturity value, r is the effective annual interest rate and n is the number of compounding periods

P = 100,000 / (1 + r)^264

Explanation: To receive $100,000 on the maturity date, the principal amount has to be invested such that it earns the effective annual interest rate for the entire 3-year period. The principal amount was calculated using the formula for future value of an investment, where the maturity value, effective annual interest rate and the number of compounding periods are known.

Answer:

x = arccos(3/4) + 2πn where n = 0,1,2,3,4, ....

Step-by-step explanation:

We can solve the equation 4cos(x) + 3 = 6 by isolating the cos(x) term on one side of the equation.

4cos(x) + 3 - 3 = 6 - 3

4cos(x) = 3

cos(x) = 3/4

Now we can find the solutions of the equation by finding the values of x that make cos(x) equal to 3/4. Since -π < x < π, we can find the solutions in the range of -π < x < π.

x = cos^-1(3/4) + 2πn, where n is an integer

x = cos^-1(3/4) + 2πn, where n = 0, 1, 2, ...

The solutions are x= cos^-1(3/4) and x = cos^-1(3/4) + 2π, x = cos^-1(3/4) + 4π

Keep in mind that cos^-1(3/4) is the inverse cosine function or arccos(3/4) so the final solution is x = arccos(3/4) + 2πn where n = 0,1,2,3,4, ....

Answer:

x = √52

Step-by-step explanation:

Triangle PLM and JLK are connected together at L, which means that they share the same vertex L and therefore, the angle at L is the same for both triangles.

Since PLM and JLK are both triangles, we know that the sum of the angles in each triangle is always 180 degrees.

Let's call the angle at L as a. So we have:

a + (180-a) = 180

We know that PL = 6 and PM = 12, so we can use the Law of Cosines to find the value of the angle a:

c^2 = a^2 + b^2 - 2ab*cos(C)

where c is the hypotenuse, a and b are the other two sides and C is the angle opposite to c.

c = PL = 6

a = PM = 12

b = JL = 4

c^2 = 12^2 + 4^2 - 2124cos(a)

36 = 144 - 48cos(a)

cos(a) = (144 - 36)/48 = (108/48) = 9/4

a = arccos(9/4)

Now we know the measure of angle a and we can use it in the equation of the sum of angles in a triangle.

a + (180-a) = 180

We also know that JL = 4 and JK = x and we can use the Law of Cosines again to find the value of x.

x^2 = 4^2 + 6^2 - 246cos(a)

x^2 = 16 + 36 - 24(9/4)

x^2 = 52

x = √52

In actuality, modern electronic calculators with advanced features are specialised computers with a specific function.

The two numbers can be rounded to the closest ten to get an estimate for the calculation 348 + 598.

Rounding 348 to the nearest 10, we get 350.

600 is the result when 598 is rounded up to ten.

Consequently, 350 + 600 = 950 is what we estimate the sum of 348 and 598 to be.

The correct calculation is 348 + 598 = 946 when using a calculator.

In comparison to the actual answer of 946, our guess of 950 is 4 higher. This indicates that we slightly overestimated the result in our estimation. Since the figures are rounded to the closest 10, there isn't much of a change, and this is reasonable.

Solving by factoring is a strategy used to solve quadratic equations, which are polynomials of the form ax^2 + bx + c = 0. The goal of this strategy is to factor the quadratic expression on one side of the equation and set each factor equal to zero to find the solutions of the equation.For example, consider the equation x^2 - 6x + 8 = 0. To solve this equation by factoring, we can first find the factors of the constant term (8) which are 1 and 8. And the factors of the leading coefficient (1) and the constant term (8) which are (1,-8) and (1,8). We can then use the distributive property to rewrite the equation as (x - 4)(x - 2) = 0.Once we have factored the quadratic expression, we set each factor equal to zero and solve for x. In this case, x - 4 = 0 and x - 2 = 0. Solving for x, we get x = 4 and x = 2. These are the solutions to the equation.We can check our solutions by plugging them back into the original equation to see if they make the equation true.x = 4 and x = 2 are the solutions of the equation x^2 - 6x + 8 = 0.It's important to note that factoring can also be used to solve equations that are not in the standard form, like x^2 - 6x + 8 = 12 by subtracting 12 from both sides of the equation, and then factor the left side.In summary, factoring is a strategy used to solve quadratic equations by factoring the quadratic expression on one side of the equation, setting each factor equal to zero, and solving for x. The solutions of the equation are the values of x that make the equation true.

Answer:

Step-by-step explanation:

Using the Law of Cosines, we can calculate the three angles of the triangle.

A = cos⁻¹((17² + 30² - 20²) / (2 x 17 x 30))

A = cos⁻¹(7 / 510)

A = cos⁻¹(0.0137254901960784)

A = 84.2°

P = cos⁻¹((20² + 30² - 17²) / (2 x 20 x 30))

P = cos⁻¹(11 / 600)

P = cos⁻¹(0.0183333333333333)

P = 70.0°

K = 180° - (84.2° + 70.0°)

K = 25.8°

Therefore, the angles of △HPK are:

Angle H = 84.2°

Angle P = 70.0°

Angle K = 25.8°

Round your final answer to the nearest tenth:

Angle H = 84.2°

Angle P = 70.0°

Step-by-step explanation:

2a + 4c = 43.5

10a + 20c = 217.5

subtract

10a +6c = 130

c = 6.25

2a + 25 = 43.5

2a = 18.5

a = 16.5

16.5 + 6.25 = 22.75

Answer:

One adult ticket costs £9.25, and one child ticket costs £6.25.

Step-by-step explanation:

Let a = price of 1 adult ticket.

Let c = price of 1 child ticket.

"A family of two adults and four children pay £43.50. for entry."

2a + 4c = 43.5

"Another family of five adults and three children pay £65."

5a + 3c = 65

We have a system of simultaneous equation in two unknowns.

2a + 4c = 43.5

5a + 3c = 65

Let's solve the system by the method of elimination. We need to add multiples of the two equations in a way that one variable will be eliminated (add to zero).

Let's eliminate the variable a. Multiply both sides of the first equation by -5  Multiply both sides of the second equation by 2. Then add them.

      -10a - 20c = -217.5

+     10a +   6c = 130

----------------------------------

                -14c = -87.5

                     c = 6.25

Now substitute 6.25 for c in the first original equation and solve for a.

2a + 4c = 43.5

2a + 4(6.25) = 43.5

2a + 25 = 43.5

2a = 18.5

a = 9.25

Answer: One adult ticket costs £9.25, and one child ticket costs £6.25.
