Answer:

A) -15

Step-by-step explanation:

The average rate of change of f(x) on interval [a, b] is given by ...

(f(b) -f(a))/(b -a)

Here, you have ...

f(x) = -2^x +70

[a, b] = [2, 6]

so the average rate of change is ...

(f(6) -f(2))/(6 -2) = ((-2^6 +70) -(-2^2 +70))/4 = (-64 +4)/4 = -16+1

average rate of change = -15

Answer:

$\displaystyle A=\dfrac{1}{2}\int_\pi^{\frac{7\pi}{6}}{(\cos{\theta}+\sin{2\theta})^2}\,d\theta$

Step-by-step explanation:

The shaded area is the area of the curve bounded by θ = π and θ = 7π/6.* A differential of area in polar coordinates is ...

dA = (1/2)r^2·dθ

So, the shaded area is ...

$\displaystyle\boxed{A=\dfrac{1}{2}\int_\pi^{\frac{7\pi}{6}}{(\cos{\theta}+\sin{2\theta})^2}\,d\theta}$

_____

* We found these bounds by trial and error using a graphing calculator to plot portions of the curve.
