The height of the goalpost is 16.45 m.

Given, Anand uses a mirror on the ground to measure the height of his school’s football goalpost.

He walks a distance of 14.75 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center.

He then steps 1.3 meters to the other side of the mirror, until he can see the top of the goalpost clearly marked in the X.

His partner measures the distance from his eyes to the ground to be 1.45 meters.

we are asked to determine the height of the goalpost = ?

As per the rule of reflection in physics,

Angle of incidence = Angle of reflection

As we can see in the picture attached, both the angles (θ) are equal.

m∠ACB = m∠ECD = 90° - θ

m∠ABC = m∠ADC = 90°

Therefore, both the triangles ΔABC and ΔEDC will be similar.

And by the property of similar triangles, their corresponding sides will be proportional.

AB/ED = CB/CD

1.45/ED = 1.3/14.75

ED = 14.75×1.45/1.3

ED = 16.45 m

Hence the height of the goal post is 16.45 m

The solution to the initial value problem in this problem is given as follows:

[tex]y = 0.0022e^{5x} - 0.8853e^{-x}[/tex]

The initial value problem is given as follows:

y''-4y'-5y = 0.

The first step is finding the roots of the characteristic equation, which is given as follows:

r² - 4r - 5.

The equation can be factored as follows:

r² - 4r - 5 = (r - 5)(r + 1).

Applying the inverse Factor Theorem, the roots are given as follows:

These roots are real, hence the format of the solution is given as follows:

[tex]y = Ae^{5x} + Be^{-x}[/tex]

Considering the initial condition at x = 1, we have that:

Ae^(5) + Be^(-1) = 0

Considering the initial condition of the derivative at x = 1, we have that:

5Ae^(5) - Be^(-1) = 2.

Adding the two equations, the condition A is obtained as follows:

6Ae^(5) = 2.

A = 2/(6e^5)

A = 0.0022.

Hence the condition B is:

B = -0.0022e^(5)/e^(-1)

B = -0.8853.

Hence the solution is:

Answer:

153.86

Step-by-step explanation:

to get the area of the circle you take the radius to the power of 2 and then multiply with π
when the radius of circle S is half the radius of circle L and circle L has radius 14 inch, then the radius of S is 7.
area = radius² * π = 7² * π = 49 * π
π is approximately 3.14
so 49*3.14 = 153.86

For given function f(x-3) = x^2- 2x+ 7, the value of f(-1) is 10

For given function f(x-3) = x^2- 2x+ 7 we need to find the value of f(-1)

i.e., we get an equation,

x - 3 = -1

x = -1 + 3

x = 2

Substitute x = 2 in given function,

f(-1) =  (-1)^2- 2(-1) + 7

f(-1) = 1 - (-2) + 7

f(-1) = 1 + 2 + 7

f(-1) = 10

4:3

we are asked to determine the coordinates of the point.

Let the given points (-10,2) be (x₁, y₁) and (-3,-5) be (x₂, y₂) and the ratio be m:n.

Where A is the final amount, P is the principal, r is the rate, and t is the time in years.

The question does not specify whether the interest rate is annual or not, but I will assume it is! To convert 15 months to years, divide it by 12 months!

[tex]\frac{15}{12}=\frac{5}{4}=1.25[/tex]

I also need the percent to be a decimal. To convert a percent to a decimal, divide by 100.

As gradients multiplied we get [tex]\frac{-4}{3}[/tex] the line segments AB and BC are not perpendicular

How to find lines are perpendicular?

Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane. Vertical and horizontal lines, or the axes of the coordinate plane, are perpendicular to one another. Two parallel lines' slopes have negative reciprocal slopes.

To find whether the line segments are perpendicular we have to first find the gradient of AB and BC

Finding the gradient of AB

A(1,3) and B(2,1)

[tex]m_{AB}[/tex]=(1-3)/(2-1)

       = [tex]\frac{-2}{1}[/tex]

       =-2

Finding the gradient of BC

B(2,1) and C(5,3)

[tex]m_{BC}[/tex]=(3-1)/(5-2)

      =[tex]\frac{2}{3}[/tex]

When we multiply the two gradients if we get -1 then the two line segments are perpendicular.

[tex]m_{AB}X m_{BC} = -2X\frac{2}{3}[/tex]

                  = [tex]\frac{-4}{3}[/tex]

As the gradient is not equal to -1 the line segments AB and BC are not perpendicular

The y-intercept is (0, 400), which represents the amount of money the radio station originally had. The x-intercept is (8, 0), which represents the number of weeks it will take for the radio station to have $0 left.

In Mathematics, the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

Similarly, the x-intercept can be defined as the point at which the graph of any function crosses the x-coordinate and the value of "y" is equal to zero (0).

For the y-intercept, x = 0 and we have the following:

y = 400 - 50x

y = 400 - 50(0)

y = 400.

For the x-intercept, y = 0 and we have the following:

y = 400 - 50x

0 = 400 - 50x

50x = 400

x = 400/50

The solution of the inequalities is x < - 3 / 2 or x > 48 / 5

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Inequality expression always have the symbols <, >, ≤ and ≥.

Therefore, let's solve the inequalities.

12x + 7 < - 11 or 5x - 8 > 40

12x + 7 < - 11

subtract 7 from both sides of the inequalities.

12x + 7 - 7 < - 11 - 7

12x < - 18

divide both sides by 12

x < - 18 / 12

x < - 3 / 2

5x - 8 > 40

add 8 to both sides of the inequalities

5x - 8 + 8 > 40 + 8

5x > 48
