Answer:

<em>− 2sin(b) / cos(2b)</em>

Step-by-step explanation:

DIFFERENTIATE W.R.T. B is a different method entirely

We simply add together the numerators and set with 2cos

then keep this number and add to sinb and square it.

then repeat initial 2 + cosb ^2 but instead of multiplying its add.

Then set the whole division to -sin (2b) squared then +1

<em> − 2cos(b)(3(sin(b))^2+(cos(b))^2) / −(sin(2b)) ^2 +1 </em>

Zolol [24]

Since a sphere's surface area is 4πr², we then need to find r as a function of time t, which is 9t (since it increases by 9 every second)+0 (the initial value)=9t. Plugging it in, we get 4π(9t)²=4π*36t²=144πt²

You want to have your carpet cleaned in your living room which measures 12’ by 14’. Company A charges $2.75 per square foot and

Sonja [21]

Answer: Company B

Step-by-step explanation:

First we must calculate the area of the carpet. Variable A represents area.

$14*12=A$

$A=168$

So the area of the carpet is 168 square feet.

To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.

$168*2.75= Company A\\$

Company A charges, $462, while Company B will charge $450 for the one room.

This means Company B has the better price.
