The equation of line that has slope 8 and passes though (2,7) is: $y=8x-9$

Step-by-step explanation:

Given

Slope of line = 8

passes through (2,7)

Equation of line in slope-intercept form is given by:

$y = mx+b$

Putting the value of slope

$y = 8x+b$

Too find the value of b, putting (2,7) in the equation

$7 = 8(2) + b\\7 = 16+b\\b = 7-16\\b = -9$

Putting b=-9 int he equation

$y=8x-9$

Hence,

The equation of line that has slope 8 and passes though (2,7) is: $y=8x-9$

Keywords: Equation of line, slope

The Sunny Days Apartment building has a cylindrical, above ground pool in the yard. The radius of the pool is 1.5 times its heig

dezoksy [38]

Answer:

5.54 feet.

Step-by-step explanation:

Let h be the height of the pool and r be the radius of the pool.

We have been given that volume of cylindrical pool in Sunny Days Apartment building is 1200 cubic feet.

We have been given that the radius of the pool is 1.5 times its height. We can represent this information in an equation as:

$r=1.5*h...(1)$

$\text{Volume of cylinder}=\pi r^2h$

Substituting equation (1) in volume formula we will get,

$\text{Volume of cylindrical pool}=\pi (1.5h)^2*h$

Substituting the given volume of pool in formula we will get,

$1200=\pi (1.5h)^2*h$

$1200=\pi*2.25*h^2*h$

$1200=\pi*2.25*h^3$

Let us divide both sides of our equation by 2.25 pi.

$\frac{1200}{2.25\pi}=\frac{\pi*2.25*h^3}{2.25\pi}$

$169.7652726=h^3$

Let us take cube root of both sides of our equation.

$\sqrt[3]{169.7652726}=h$

$5.537=h$

$h=5.537\approx 5.54$

Therefore, the height of the pool is approximately 5.54 feet.
