What formula is used to find the rate of change
Yuliya22 [10]

Answer:

Average rate of change uses the slope formula (AKA rise over run AKA change in y over change in x AKA y2-y1 over x2-x1). To find y2 and y1, plug the x-values from your interval end points into the function f(x). Say f(1) and f(a). i really hope that helps

Alex invests $2,000 in a company's stock. After a year, the value of Alex's stock has increased to $2,500. What rate of return h
Kay [80]

The rate of interest is 25%

<u>Explanation:</u>

Given:

Principal, P = $2,000

Amount, A = $2500

Time, t = 1 year

Rate of Interest, r = ?

We know:

Amount = P(1+\frac{r}{100})^t

On substituting the value we get:

2500 = 2000 (1 + \frac{r}{100})^1\\ \\\frac{25}{20}= (1+\frac{r}{100})\\

\frac{5}{20} = \frac{r}{100}\\  \\r = \frac{100 X 5}{20} \\\\r = 25

Therefore, the rate of interest is 25%

PLEASE HELP!! I’LL GIVE BRAINLY
LiRa [457]

Being that the triangle has a center of dilation at (0,0) you must contract the points towards (0,0). The scale factor is 1/3 so you must divide the difference in location of the points on the X and Y axis by a scale of 1/3.

1/3 of 9 = 3 , y = 3

1/3 of -6 = -2 , x = -2

by changing these points a new triangle will be formed
