Help please with this math question
Vanyuwa [196]
To solve this question, simply use the formula to find the volume of the cylinder,

V = Pi r^2 • h

V = 3.14 • 4^2 • 4.

Then compare the value for volume to the closest number on the number line. Is it in between 2 numbers, exactly one number on the number line or very close to one number as in the number line.

Inverse for f(x)=1/2x+3
Semenov [28]

Answer: f^{-1}(x)=2x-6

Step-by-step explanation:

To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.

y=\frac{1}{2}x+3        [switch x and y]

x=\frac{1}{2}y+3        [subtract both sides by 3]

x-3=\frac{1}{2} y        [multiply both sides by 2]

y=2x-6

Now, we know that  f^{-1}(x)=2x-6.

Answer:

\large\boxed{f(4)=-1292}

Step-by-step explanation:

f(n)=-5f(n-1)-2\\\\f(1)=10\\\\f(2)=-5f(2-1)-2=-5f(1)-2\\\text{put}\ f(1)=10:\\f(2)=-5(10)-2=-50-2=-52\\\\f(3)=-5f(3-1)-2=-5f(2)-2\\\text{put}\ f(2)=-52\\f(3)=-5(-52)-2=260-2=258\\\\f(4)=-5f(4-1)-2=-5f(3)-2\\\text{put}\ f(3)=258\\f(4)=-5(258)-2=-1290-2=-1292
