13. When a diabetic takes long-acting insulin, the insulin reaches its peak effect on the blood sugar level in about three hours. This
effect remains fairly constant for 5 hours, then declines, and is
very low until the next injection. In a typical patient, the level of
insulin might be modeled by the following function on the right.
401 +100
Osts3
220 3 f(t) =
-801 + 860 8 60
10 Here, f(t) represents the blood sugar level at time t hours after the time of the injection. If a patient
takes insulin at 6 am, find the blood sugar level at each of the following times.
a. 7 am
b. 11 am
c. 3 pm
d. 5 pm

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
