Step-by-step explanation:

The problem has a misspelling. The word should be "principal" not "principle."

Formula for simple interest:

I = Prt

where I = amount of interest

P = principal

r = annual rate of interest

t = time in years

I = Prt

509.60 = 910.00 * r * 8

910 * r * 8 = 509.6

7280r = 509.6

r = 0.07

The interest rate is 0.07 as a decimal.

To write it as a percent, we multiply the decimal by 100.

0.07 = 0.07 * 100% = 7%

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
