f(d) = 11(1.01)^d
Part A:
f(d) = 11.79
11.79=11(1.01)^d (1.01)^d = 11.79/11 (1.01)^d = 1.071818 d = log 1.071818 /log 1.01
d = 6.97
Part B:
y- intercept is obtained when domain = 0
d = 0 ⇒ f(0) = 11(1.01)^0 = 11*1 = 11
f(d) = 11
Part C:
Average rate of change
A.f/Ad=
(f(7)-f(2))/(7-2) = (11(1.01)^7-11(1.01)^2)/5 = 0.57/5 =

Step-by-step explanation:
Answer: The net change to her banking account balance is $83.22.
Step-by-step explanation:
Hi to answer this question we have to analyze the information given:
She spent $36.50 plus 8% tax. ( to calculate the tax amount we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Finally, adding to the total cost.
64.42 +18.8 = $83.22
