Step-by-step explanation:
Given data
Cost of merchandise= $750
Discount= 15%
Let us find the amount of the discount
=15/100*750

Area of circle is given as:

Where 
To find radius of a circle circumscribing an equilateral triangle, we use the expression

Where, a is the length of sides of the equilateral triangle. Therefore:-
We can then proceed and calculate the area of the circle as follows:-

*The attached picture illustrates what the circumscribed equilateral triangle looks like
Answer:
0.64 seconds.
Step-by-step explanation:
When it hits the ground h(t) = 0.
0 = -16t^2 + 4t + 4
-4(4t^2 - t -1) = 0
t = [-(-1) +/- sqrt (1 - 4*4*-1)] / 8)
t = 0.64, -0.39
answer is 0.64 seconds.
