A ladder that is 21 feet long is propped against a building. The bottom of the ladder was placed 4 feet from the base of the building. How high up on the building does the ladder reach? Round the answer to the nearest tenth of a foot
Answers
Answer:
20.62 feet
Step-by-step explanation:
The ladder propped against a building forms a right angle triangle
Height of the ladder (hypotenuse) = 21 feet
Base of the ladder from the building (adjacent) = 4 feet
Height of the building (opposite) = x feet
Hypotenuse ² = opposite ² + adjacent ²
21² = x² + 4²
21² - 4² = x²
441 - 16 = x²
425 = x²
x = √425
= 20.62 feet
Answer: 20.62 ft or rounding it to 20.6 ft

Find the x and y Intercepts
Answers
Answer:
x-intercept(s): (3,0)
y-intercept(s): (0,−2)
Step-by-step explanation:
Answer:
x=3 and y=-2
Step-by-step explanation:
2x - 3y = 6
cancel out the y
2x - 3(0) = 6
2x = 6
divide both sides by 2
x = 3
2x - 3y = 6
cancel out the x
2(0) - 3y = 6
-3y = 6
divide both sides by -3
y = -2

f(x)= √x+3. Find the inverse of f(x) and it's domain
Answers
Step-by-step explanation:
f(x) = √x + 3
y = √x + 3
√x = y - 3
x = (y - 3)²
Hence inverse of f(x) = (x - 3)² and its domain is x >= 3.
The required domain of the inverse function F(x)= (x-3)^2 is given by ≥3
f(x)= √x+3
What is inverse function?The inverse function can be defined as the transverse of function.
F(x) = y
y = √x + 3
x= (y - 3)^2
or
for inverse function
F(x) = (x-3)^2
The domain of function is given by greater and equal to 3
The required inverse function is F(x) = (x-3)^2 and its domain is greater and equal to 3.
