A sphere has a radius of 2x + 5. Which polynomial in standard form best describes the total surface area of the sphere? Use the
faust18 [17]
Start with the given formula for the surface area of a sphere.

S = 4 \pi r^2

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.

S = 4 \pi (2x + 5)^2

S = 4 \pi (4x^2 + 20x + 25)

S = 16 \pi x^2 + 80 \pi x + 100 \pi

What is an equation of the line that passes through (2,2) and is parellel to the line y=7x
laila [671]

Answer:

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

Step-by-step explanation:

Given:

a line y=7x

To Find:

Equation of line passing through ( 2, 2) and is parellel to the line y=7x

Solution:

y=7x     ...........Given

Comparing with,

y=mx

Where m =slope

We get

Slope = m = 7

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.

Now the equation of line in slope point form given by

(y-y_{1})=m(x-x_{1})

Substituting the points and so we will get the required equation of the line,

(y-2)=7(x-2)=7x-14\\\\y=7x-12......Equation\ of\ line

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12
