Use your graphing calculator to produce a sine regression model for the data in the table. Round a, b, c, and d to the nearest 0.001.
a.
y = 0.519 sine (4.974 x minus 3.965) + 0.812
b.
y = 4.974 sine (0.519 x minus 0.812) + 3.965
c.
y = 0.519 sine (4.974 x minus 0.812) + 3.965
d.
y = 4.974 sine (0.519 x minus 3.965) + 0.812

Someone answer asap 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)) =
