5 In 1980, the average cost, C, of having a book published by Priced For Inflation
Publishing Company was $800. In 2000, the cost was about $1800. Write a Linear
Function that represents the cost of tuition as a function of the number of years, t,
since 1980. Utilize your Function to predict the cost in 2020.*

C(t) = 50t + 800; 2020 =
$2,800
t(C) = 50C + 800; 2020 =
$2,800
C (t) = 800t + 50; 2020 =
$780
C (t) = 800t + 50; 2020 = $850

Asegment in the complex plane has a midpoint at 7 – 2i. if the segment has an endpoint at 11 – 3i, what is the other endpoint?

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.

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)) =
