Help me please I don’t know what to do

To find an inverse function first replace f(x) with y

f(x) = 8*sqrt(x)
y = 8*sqrt(x)

Then, simply switch the places of the x and y.

x = 8sqrt(y)

Now solve for the new y by squaring both sides (to get rid of the root)

x^2 = 64y

divide to get

y = x^2/64. This is the inverse function or option C.

2.6pi is the circumference
circumference is 2pi*r
so 2.6pi=2pi*r
2.6=2r
r=1.3
The radius should be 1.3 meters

4(5x-6)=2(8x+10) how to solve

Pavel [41]

Hello! :)

Answer:

$\boxed{X=11}$

*The answer must have a POSITIVE sign!*

Step-by-step explanation:

Expand with distributive property: a(b+c)=ab+ac

4*5=20

6*4=24

20x-24

2*8=16

2*10=20

16x+20

20x-24=16x+20

First, you add by 24 both sides of an equation.

20x-24+24=16x+20+24

20x=16x+44

You subtract by 16x both sides of an equation.

20x-16x=16x+44-16x

4x=44

Then, you divide by 4 both sides of an equation.

4x/4=44/4

Divide by the numbers from left to right.

44/4=11

<u><em>X=11 is the final answer</em></u>

Hope this helps!

Have a nice day! :)

1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2)<br> what is v?

Irina-Kira [14]

Answer:

The value of v is 3/4.

Step-by-step explanation:

First, you have to convert mixed number into improper fraction :

$1 \frac{1}{2} \\ = \frac{2 \times 1 + 1}{2} \\ = \frac{3}{2}$

In order to find the value of v, you have to substract 3/4 to both sides :

$\frac{3}{2} = v + \frac{3}{4}$

$\frac{3}{2} - \frac{3}{4} = v + \frac{3}{4} - \frac{3}{4}$

$v = \frac{3 \times 2}{2 \times 2} - \frac{3}{4}$

$v = \frac{6}{4} - \frac{3}{4}$

$v = \frac{3}{4}$
