Answer:

Step-by-step explanation:

f(x)=x^+4x+2 First, let's evaluate when x=3, x=4 and x=5.

f(3) = 3²+4(3)+2 = 9 + 12 + 2 = 23

f(4) = 4²+4(4)+2 = 16 + 16 + 2 = 34

f(5) = 5²+4(5)+2 = 25 + 20 + 2 = 47

Now, let's find the rate of change.

34 - 23 = 11

47 - 34 = 13

Finally, the average rate of change.

(11 + 13) / 2 = 12

What is the area of sector ghp

Klio2033 [76]

<h2>Explanation:</h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any sector, so I'll help you in a general way and providing my own example.

A sector is a region of a circle between two radii. Suppose you have a central angle $\theta$ degrees, the sector can be found as:

$s=\frac{\theta}{360}\times\pi r^{2}$

Suppose that the radius of the circle is $4cm$ and the central angle is 90 degrees, therefor the sector is:

$s=\frac{\theta}{360}\times\pi r^{2} \\ \\ s=\frac{90}{360}\times\pi (4)^{2} \\ \\ s=\frac{1}{4}\times 16\pi \\ \\ \boxed{s=4\pi cm^2}$
