The dome of the igloo is in the shape of a parabola, and the height of the igloo in inches is given by the function ƒ (x) = a (x - h)2 + k. Use the graph to find an equation for ƒ (x).

Vertex (40, 48)
h = 40 k =48
point (60, 36)
I need help ASAP!

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)) =

The weekly revenue for a company is r = 3p^2 + 60p + 1060, where p is the price of the company's product. what price will result in a revenue of $1200.

Is the figure congruent? yes or no?
