A glass cylinder is completely filled with 24x^5y^8 cubic inches of salt solution. The jug has a base area of 4x^5 square inches
xz_007 [3.2K]
We know that

volume of a cylinder=area of the base*height
area of the base=4x^5  in²
height=<span>24x^5y^8/ 4x^5 in
volume=</span>24x^5y^8 in³

height=24x^5y^8/ 4x^5 ------> (24/4)*(x^5/x^5)*(y^8)------> (6)*(1)*(y^8)-----> 6y^8

the answer is
B: 6y^8

Passes through the points (−4, 2) and (12, 6)?
svlad2 [7]

<u>I'll assume you need to find the equation of the line that passes through those points.</u>

Answer:

\displaystyle y-2=\frac{1}{4}(x+4)

Step-by-step explanation:

<u>Equation of a Line:</u>

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

The given points are (-4,2) and (12,6), thus:

\displaystyle y-2=\frac{6-2}{12+4}(x+4)

Operating:

\displaystyle y-2=\frac{4}{16}(x+4)

Simplifying, the equation in point-slope form is:

\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}
