Answer:

The answer is the option A \frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}

Step-by-step explanation:

we know that

The measure of \pi radians is equal to 180\°

so by proportion

Find the measure in radians of  45\°

\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{45}\frac{radians}{degrees}\\ \\x=(45/180)*\pi \\ \\x=\frac{\pi}{4}

Find the measure in radians of  90\°

\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{90}\frac{radians}{degrees}\\ \\x=(90/180)*\pi \\ \\x=\frac{\pi}{2}

therefore

In radian measure the angles are

\frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}

F(x) = x2 + 10<br> What is the average rate of chan<br> hange of f over the interval [-2, -1]?
Readme [11.4K]

The average rate of change is given by [f(b) - f(a)]/(b - a), where a and b represent the interval [a, b].

Let a = -2

Let b = -1

[(-1)^2 + 10 - ((-2)^2 + 10)]/(-1 -(-2))

[1 + 10 - (4 + 10)]/(-1 + 2)

[1 + 10 -4 -10]/(1)

[1 - 4]/(1)
