Jerome's average balance checking account pays simple interest of 7.2% annually and he made $5.28 in interest last month. what was jerome's average balance last month? $880.00 (apex answer)

Yes, the Average balance on the last month is $ 880.

Step-by-step explanation:

Let P be the balance on last month in his account,

Here, the annual rate of interest = 7.2 %,

Hence, the monthly rate of interest, r = = 0.6 %

Also, the interest for one month with this rate of interest = $ 5.28

And, Time, t = 1 month

Thus, By the formula of simple interest,

Hence, the balance on the last month = $ 880.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
