What is the rate of the interest on $560 for two years is $145.60?

The rate of interest is 13%.

Step-by-step explanation:

Given,

Principal (P) = $560

Interest (I) = $145.60

Time (T) = 2 years

To find the rate of interest

Formula

If P principal was invested for T years at r% simple interest, the interest will be I =

So,

Putting the values of P, I, T we get,

145.60 =  

or, r =

or, r = 13%

Hence,

The rate of interest is 13%.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
