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

Answer:
= 42
Step-by-step explanation:
The n th term I obtained in your previous question, that is
= 4n + 2
To find the 10 th term substitute n = 10 into the formula
= 4(10) + 2 = 40 + 2 = 42
Answer:
The equation of the perpendicular line would be y = -5/2x + 7
Step-by-step explanation:
In order to find this line, we must first find the slope of the original line. We do this by solving for y.
2x - 5y = 6
-5y = -2x + 6
y = 2/5x - 6/5
This shows us a slope of 2/5. TO find the perpendicular slope, we use the opposite and reciprocal. This means we negate 2/5 to get -2/5 and then we flip it to get -5/2. Now that we have this, we can use the slope and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 2 = -5/2(x - 2)
y - 2 = -5/2x + 5
y = -5/2x + 7
