Use the table of integrals, or a computer or calculator with symbolic integration capabilities, to find the indefinite integral.
nignag [31]

Answer:

-\frac{3}{11}\ln(\cot t + \csc t)+C

Step-by-step explanation:

We are given:  \int \frac{3}{x\sqrt{121-x^2}} dx

We will use integration by parts.

x = 11 \sin t\\dx = 11 \cos t \: dt

\int \frac{3}{x\sqrt{121-x^2}} dx=\int \frac{3* 11 \cos t \: dt}{11 \sin t\sqrt{121-121\sin^2 t}} =\int \frac{3* 11 \cos t \: dt}{11 \sin t*11\cos t}} =\\\\= \frac{3}{11} \int \csc t = -\frac{3}{11}\ln(\cot t + \csc t)+C

What is the volume of A cube with the surface area of 600 in.²
GrogVix [38]

Answer:

1000 in³

Step-by-step explanation:

A cube has 6 square faces

Given the surface area of the cube = 600 in², then

The area of 1 face = 600 ÷ 6 = 100 in²

The area of a square = s² ( where s is the measure of a side ), thus

s² = 100 ( take the square root of both sides )

s = \sqrt{100} = 10

The volume (V) of the cube = s³, so

V = 10³ = 1000 in³
