Answer:
Approximately 10.39 ft.
Step-by-step explanation:
First, draw a short diagram to understand the sides of the right triangle.
The 12 foot ladder leaning against the building would be the hypotenuse and because the bottom of the ladder is 6 feet from the house, that would be the bottom leg. We are trying to figure out the leg to the left (the top of the ladder from the ground.
To solve this, we must use the converse of the Pythagorean Theorem. To do this, we can set up the following equation.
12^2 - 6^2
144 - 36 = 108
Then we must find the square root of 108, which is approximately 10.39 feet.
Answer:
gof(x) = x²+8x+15
Step-by-step explanation:
gof(x) = g(f(x))
f(x) = x + 4 and g(x)=x²-1
Substituting
gof(x) = g(f(x)) = g(x + 4) = (x+4)²-1
gof(x) = x²+8x+16 -1 = x²+8x+15
That is if f(x) = x + 4 and g(x)=x²-1, gof(x) = x²+8x+15
