Q2 Question 2 - Combining Functions 1On most state highways, the fine for speeding depends on the speed of the car. On a certain state highway, the fine for driving 70 mph is $25 and the fine for driving 85 mph is $100. On this particular road, when a car brakes suddenly, the function S(d) = √ (under the square root) 40d can be used to approximate the speed of a car (in mph) when it leaves a skid mark of length d feet on the road.
a) Using the information provided, write a linear equation that represents the fine for speeding, F,
as a function of the speed in mph on the state highway.
Part b) Find (F x S)(d) and explain what this function can be used for in context of the problem.

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)) =
