Aman invests
$3700
in three accounts that pay
5%,
6%
, and
7%
in annual interest, respectively. he has
3
times as much invested at
7%
than he does at
5%
. if his total interest for the year is
$234
, how much is invested at each rate?

First account $3700 at 7% Interest annually = $259.00
Second account $3700 at 6% interest annually = $222.00
Thirs account $3700 at 5% interest annually = $185.00

He has 3 times as much invested at 7% than he does at 5%.
If his total interest for the year is $234, how much is invested at each rate?
Doesn't make any sense - please rephrase.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

f(-2) = -3f(1) = 6 . . . estimated from f(x) = (x+2)^2-3, which matches points on the graph (-1,-2) and (0, 1)

so the change in y-value for function f is (6 )) = 9.

the table tells us

g(-2) = 1g(1) = 31

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

Iam thinking the answer is a.) knew
