By the product and chain rules,
f'(x) = g(h(x)) + x g'(h(x)) h'(x)
Then
f'(3) = g(h(3)) + 3 g'(h(3)) h'(3)
f'(3) = g(4) + 3 g'(4) (-2)
f'(3) = g(4) - 6 g'(4)
f'(3) = 2 - 6(3)
f'(3) = -16
2. By the secant rules,
BC² = DC*(DC +diameter)
Substituting the given information, you have
8² = 4*(4 +2*radius)
64 = 16 +8*radius
48/8 = radius = 6
radius = AB = 6
3. By the Pythagorean theorem,
AC² = BC² +AB²
Substituting the given information, you have
12² = 9² +AB²
144 -81 = AB² = 63
AB = √63 = 3√7
radius = AB = 3√7
Answer:

Answer: 3. $19.95 + $5.99y
Step-by-step explanation:
Answer:
8 x 3 = 24, 24 divided by 2 = 12
I got 3(base of triangle) from subtracting 4 from 7.
12 x 2 = 24(area of two triangles)
16 x 4 = 64(area of long rectangle below)
I got 16 by the given length below, and i got the height from the middle which is the height that says 4.
Add both given areas:
24 + 64 = 88 square inches is your area.
