Answer:

Step-by-step explanation:

The geometric mean relation says ...

16 = √(8n)

256 = 8n . . . . . square both sides

32 = n . . . . . . . . divide by 8

What is Cos^-1( -sq2/2)? Pleaseee help ASAPOL

Answers

Answer:

s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant

Step-by-step explanation:

Take the integral:

integral cos^(-1)(-(q^2 s)/2) ds

For the integrand cos^(-1)(-(q^2 s)/2), substitute u = -(q^2 s)/2 and du = -q^2/2 ds:

= -2/q^2 integral cos^(-1)(u) du

For the integrand cos^(-1)(u), integrate by parts, integral f dg = f g - integral g df, where

f = cos^(-1)(u), dg = du, df = -1/sqrt(1 - u^2) du, g = u:

= -(2 u cos^(-1)(u))/q^2 + 2/q^2 integral-u/sqrt(1 - u^2) du

Factor out constants:

= -(2 u cos^(-1)(u))/q^2 - 2/q^2 integral u/sqrt(1 - u^2) du

For the integrand u/sqrt(1 - u^2), substitute p = 1 - u^2 and dp = -2 u du:

= -(2 u cos^(-1)(u))/q^2 + 1/q^2 integral1/sqrt(p) dp

The integral of 1/sqrt(p) is 2 sqrt(p):

= (2 sqrt(p))/q^2 - (2 u cos^(-1)(u))/q^2 + constant

Substitute back for p = 1 - u^2:

= (2 sqrt(1 - u^2))/q^2 - (2 u cos^(-1)(u))/q^2 + constant

Substitute back for u = -(q^2 s)/2:

Answer: = s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant

x = -11.6

-(-11.6) + 1.2 = 12.8

Isolate the variable by dividing each side by factors that don’t contain the variable.

Answer:
X= -11.6

Step-by-step explanation:

Step 1 - Subtract 1.2 from both sides.
-x + 1.2 - 1.2 = 12.8- 1.2
-x = 11.6

Step 2: Divide both sides by -1.
-x 11.6

Answers

Answer:

24w - 16u + 48

Step-by-step explanation:

by distributive property you have to distribute the number on the outside to the number inside the parenthesis

Answer:

24w - 16u + 48

Step-by-step explanation:

Ok so,

to distribute means to multiply -8 with all of the numbers inside of the parentheses in order to get rid of it. So it should look like this.

-8 x -3w = 24w

-8 x +2u = -16u

-8 x -6 = 48

Now you just take all of the numbers and put them together which will be

24w - 16u + 48
