Answer:
The answer is below
Step-by-step explanation:
The ramp has the form of a triangle. The height of the ramp is the vertical side of a triangle, the top of the frame is the hypotenuse while the length of the ramp is the base side of the triangle.
Let the hypotenuse be b, length be a and height be c Hence:
b² = a² + c²
b² = 3² + 5²
b² = 9 + 25
b² = 34
b = 5.83 feet
B) The plywood needs to be 5.83 feet long
C) Since the top of the ramp is 10 feet, let us assume the height of the ramp to be 6 feet, hence, the length of the ramp a is:
10² = a² + 6²
100 = a² + 36
a² = 64
a = 8 feet

Answer:
f(-5) = 5
Step-by-step explanation:
Step 1: Define
f(x) = -x² - 7x - 5
f(-5) is x = -5
Step 2: Substitute and Evaluate
f(-5) = -(-5)² - 7(-5) - 5
f(-5) = -25 + 35 - 5
f(-5) = -25 + 30
f(-5) = 5
