Select the correct answer.
What is the average rate of change of Ax), represented by the graph, over the interval [0, 2)?
A.2
B.1
C.0.5
D.-0.5

The average rate of change for the interval [0,2] is 2.

Step-by-step explanation:

In order to find the points to complete the rate of change look at your graph. The intervals (0 and 2) are the x intercepts. If you look at the graph the y intercepts for 0 is 4, and the y intercept for 2 is 8. Then you use the slope formula, y2-y1/x2-x1, 8-4 is 4 and 2-0 is 2, four divided by two is two.

cosine

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
