Answer:
$970. 19
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r)^t
where Accrued amount is to be determined
P = principal; $870
r = 3.7% = 0.037
t = number of years = 3
Therefore
Accrued amount = 870 (1 + 0.037)^3
Accrued amount = 870 x 1.037^3
= 870 x 1.1152
= 970. 19
Hence balance of the account at the end of 3 years is $970. 19
since y varies directly with y then
y = kx ( k is the constant of variation )
to find k use y = 3 when x = 2
k = =
equation is : y = x
When x = 1 then y = × 1 =

Answer:
<h2> 2.32dollar/mile</h2>
Step-by-step explanation:
step one:
Given the function
y = 14 +2.31x + 4.50
we can solve for the rate of change by applying differentiation.
step two:
differentiating y which is cost with respect to x which is the miles
dy/dx= 0+2.32+0
dy/dx=2.32
Hence the rate of change of cost in the dollar to a mile is
2.32dollar/mile
