Answer:
cosx = sqrt(15)/4, -sqrt(15)/4
Step-by-step explanation:
cos²x = 1 - sin²sin x
cos²x = 1 - (1/4)²
cos²x = 15/16
cosx = sqrt(15)/4, -sqrt(15)/4
It's between 11 and 12.
8 9 10 -11 12- 13 14 15
Let 'x' represent the number of baskets and let 'y' be the total cost.
Since the paint costs 14.50 and each basket cost 7.25, then we have the following function:

To find the cost of 4 baskets, we can make x = 4 and solve for y:

therefore, the cost of painting 4 baskets is $43.50
