Answer:

<em>The total interest earned after subtracting the monthly $35 </em>

<em>service fee = $975 - $35 = $940</em>

Step-by-step explanation:

Bank fee cost per month = $35

Interest rate per month = 1%

The total amount in the account until the 15th = $100,000

The total amount in the account from the 15th to the 30th = $95,000

Interest Earned?

<em>Interest earned for first 15 days:</em>

                               = $100,000 times 1%/2

                               = $100,000 times 0.001/2

                               = $500

<em>Interest earned from 15th to the 30th:</em>

<em>                                  </em>= $95,000 times 1%/2

                                 = $95,000 times 0.001/2

                                 = $475

Interest earned for <em>first 15 days + Interest earned from 15th </em>

<em>to the 30th =  </em>$500 + $475 = $975

So, the total interest earned after subtracting the monthly $35

service fee = $975 - $35 = $940

The lateral area of a cylinder is 325 pi inch^2. The radius is 13 in. Find the surface area and volume. Please show all work!!!
USPshnik [31]
Answer:

Surface area =  663π in².
Volume = (676/3)π in² ≈ 225.33 π in²

Explanation:


1) We know the radius and the lateral area.

2) With the radius you can find the areas of the top and the bottom.

For that, you use the formula: 

area of the top = area of the bottom = π r² 


∴ π (13 in)² = 169π in² (each)


3) Then, the surface area is the sum of the lateral area and the two bases (top and bottom)

surface area = lateral area + bottom area + top area = 325π in² + 2×169π in² = 663π in².

3) You  can also find the height of the cylinder.

Use the formula: lateral area = 2π r h


∴ h = lateral area / [2 π r]

⇒ h = 325 π / [ 2π (13) ] = 12.5 in


4) With  the height you can find the volume.

Use the formula: V = (4/3) π r³ 

∴ V = (4/3) π (13 in)³ = (676/3)π in² ≈ 225.33 π in²

White raven [17]

Answer:

Down here ↓↓↓↓↓↓

Step-by-step explanation:

13:

It is a function, notice that if you draw a vertical line anywhere, it doesn't pass two points.

Domain : All real numbers (x-values)

Range : 2 (y-values)

14:

Not a function, if you draw a vertical line through one point, it will hit two others.

Domain : -3

Range : 4 , 0, -4

15:

It is a function, no two points in any vertical line.

Domain: All real numbers

Range: All real numbers

16:

Not a function, two points in one line

Domain : -5 ≤ x ≤ 5

Range: -2 ≤ y ≤ 2
