Answer:
Depth = 14 ft Length = 20 ft width = 12 ft
Step-by-step explanation:
Given that an architect is designing a swimming pool
Let length = x
width = x-8
Height = x-6
Then volume of swimming pool = base area x height
base area = area of triangle = 
Volume = 
Solving we find that x=20
Verify:
Length = 20: Width = 12: and height = 14
Volume = 1/2 (20)(12)(14) = 1680 ft ^3
sin 30 = .5 and cos 60 = .5
sin 60 = sqrt(3) / 2 and cos 30 = sqrt(3) / 2
answer - cos 60 and cos 30
The formula for the sum of n terms in an arithmetic progression is:
S = n/2 * (2a + (n-1)d)
Here, the common difference, d, is 8 and the first term, a, is 1. Substituting these into the formula, we get:
S = n/2 * (2*1 + 8(n - 1))
S = n + 4n² - 4n
S = 4n² - 3n
The answer is A.
