Answer:
530 in ^2
Step-by-step explanation:
The figure given is a triangle
We use the formula for the area of a triangle
A = 1/2 bh where b is the length of the base and h is the height
The height is perpendicular to the base( at 90 degrees)
A = 1/2 ( 26.5) * ( 40)
= 530 in ^2
H'(x) = 2f'(x)
h'(1) = 2*f'(1) = 2*4
h'(1) = 8
Answer:
33
Step-by-step explanation:
Substiture x for 3
8*3*2-5*3
= 33
