The top of a ladder is placed against the side of a house. The ladder is 15 feet long and the wall is 12 feet high. How far from the wall will the base of the ladder by positioned if the top ladder meets the top of the wall?

Answers

Answer:

9 ft

Step-by-step explanation:

The ladder is 15 feet long

The wall is 12 feet high

Therefore the distance between the base of the wall and the ladder can be calculated by applying phythagoreans theory

c^2= a^2 + b^2

15^2 = a^2 + 12^2

225= a^2 + 144

225-144= a^2

a^2= 81

a= 9 ft

Answers

Answer:

green line:

rise= -6

run= 3

rise/run = slope

therofore the slope = -6/3 = -2

blue line:

rise=3

run=6

rise/run = slope

therofore the slope = 3/6 = 1/2

Answer:

- 2 and [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (0, - 1) ← 2 points on the green line

m = [tex]\frac{-1-5}{0+3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2

Repeat with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (6, 0) ← 2 points on the blue line

m = [tex]\frac{0+3}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Since the product of the slopes = - 2 × [tex]\frac{1}{2}[/tex] = - 1

Then the lines are perpendicular

90-x=180
Subract 90 from 180
So there for x is 90

Directions: if l || m solve for x and y

Answers

Answer:

x = 24

y = 15

Step-by-step explanation:

Since, angles (3x - 29)° and (6x - 7)° is a pair of consecutive exterior angles,

Therefore, (3x - 29)° + (6x - 7)° = 180°

9x - 36 = 180

9x = 180 + 36

x = [tex]\frac{216}{9}[/tex]

x = 24

Therefore, (3x - 29)° = 3(24) - 29

                                  = 43°

Since, angles (3x - 29) and (8y + 17) is a linear pair.

(3x - 29)° + (8y + 17)° = 180°

43° + (8y + 17)° = 180°

8y + 60 = 180

8y = 120

y = 15

Therefore, x = 24 and y = 15 will be the answer.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second.
Equation:
y=-16x^2+267x+107

Answers

Answer:

The rocket will reach the maximum height after 8.34 seconds.

Step-by-step explanation:

We need to take the derivative of the function and set it to 0.

[tex]y' = -32x + 267 = 0\\32x = 267\\x = 8.34[/tex]

The maximum height of the rocket at x = 8.34375 will be 1,220.89.

What are the maxima and minima of a function?

For the maximum value of the function if f''(x) < 0 and for the minimum value of the function if f''(x) > 0.

The maximum and minimum value of the function is at f'(x) = 0.

A rocket is sent off from a pinnacle. The level of the rocket, y in feet, is connected with the time after send-off, x like a flash, by the given condition.

The equation is given below.

y = -16x² + 267x + 107

Differentiate the function and put it zero to get the value of time that is 'x' will be given as,

y' = 0

(d/dx)(-16x² + 267x + 107) = 0

-32x + 267 = 0

32x = 267

x = 8.34375

Then the maximum height of the rocket at x = 8.34375 will be given as,

y = -16(8.34375)² + 267(8.34375) + 107

y = -1,113.89 + 2,227.78 + 107

y = 1,220.89

The maximum height of the rocket at x = 8.34375 will be 1,220.89.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Let the total cost be y,
According to the given condition,
Total cost = 7 + 2t
where 2t is the total cost of the toys purchased.
y = 7 + 2t
