Answer:

Step-by-step explanation:

Here, we want to get the value of angle DEF

we have this as ;

Angle DEF = 1/2 * DOF

1/2 * 150 = 75

This is because angle at the center is twice the angle at the circumference

Given the function f(x) = 5^x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average r

Wewaii [24]

Table of the graph:
x: <em></em>1 2 3
y: 5 25 125

Average Rate of Change = $\frac{y_{2}-y_{1} }{x_{2} - x_{1} }$

Section A = 25-5/2-1 =20/1 =20
Section B = 125 - 25/ 3-2 = 100/1 = 100

So, Section B is 5 times greater than A.
Section B is greater because the slope of two points is greater than points in Section A.
