The moon's distance from Earth varies in a periodic way that can be modeled by a trigonometric function. When the moon is at its perigee (closest point to Earth), it's about 363,000 km away. When it's at its
apogee (farthest point from Earth), it's about 406,000 km away. The moon's apogees occur 27.3 days
apart. The moon will reach its apogee on January 2, 2016.
Find the formula of the trigonometric function that models the distance D between Earth and the moont
days after January 1, 2016. Define the function using radians.
D(t)

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)) =

Witch represents the inverse of the function f(x)=1/4x-12
