Please help! The radius of a sphere is claimed to be 3.0 inches, correct to within 0.01 inch. Use linear approximation to estima
Vilka [71]

Answer:

0,36π inches³ or simply 1.13 inches³

Step-by-step explanation:

In this case, first, we need to calculate the volume of the sphere with the formula:

V = 4πr³/3

Replacing the data we have:

V = 4π(3)³/3

V = 36 in³

Now that we have the volume we need to calculate the resulting error. In this case, using linear approximation we have to use the derivates of V and r, so we have the following:

If V = 4πr³/3

Then the derivate of V (dV) would be:

dV = 4π*3*r²/3 dr

Where dr is the error of radius so:

dV = 4π*r² dr

Solving for dV:

dV = 4*3.14*(3)²*(0.01)

dV = 1.13 in³

So at the end, we just report the volume of the sphere as

V = 36 ± 1 in³

dV =

Hank and Lynn are both paying off car loans. • Hank paid $2,000 up front when he bought his car, and he pays $200 each month. •
8090 [49]

Answer:

Yes

Step-by-step explanation:

<h3>Hank</h3>

Hank paid $2,000 upfront when he bought his car, and he pays $200 each month.

<u> This relation is:  </u>

  • H(x) = 2000 + 200x

This is proportional but not directly proportional.

<h3>Lynn</h3>

Lynn did not pay any money upfront when she bought her car, and she pays $275 each month.

<u>  This relation is:  </u>

  • L(x) = 275x

This is directly proportional.

<u>So the answer is:</u>

Yes, the relationship between the number of months and the total amount paid is proportional for both Hank's and Lynn's loans.
