you need to find m and b

m is the slope (rise over run) in this case it is 1 up, then over 2.

and b is the Y intercept. or in other words, the spot where the line cuts through the y-axis(vertical axis). in this case, it is -2.

A cylinder has a height of 17 centimeters and a radius of 13 centimeters. What is its volume?
Use a 3.14 and round your answer the nearest hundredth.

Answers

Answer:

Check explanation

Step-by-step explanation:

There are two ways to solve this, I'm not sure which way is the correct one:

1. Solving with 3.14

V=πr²h

V=(3.14)(13)²(17)

V=(3.14)(169)(17)

V=(3.14)(2873)

V=9021.22

9021.22 rounded to the nearest hundredth is 9021.22

2. Solving with π (I used a calculator to solve with π)

V=πr²h

V=π(13)²(17)

V=π(169)(17)

V=π(2873)

V=9025.79569376

9025.79569376 rounded to the nearest hundredth is 9025.8

The question says to use 3.14 so it can be method 1, but the question also asks to round to the nearest hundredth and method 2 leads me to actually being able to round so it can be suspected that method 2 is the correct way. Whichever you think is best can be chosen and sorry if this isn't a clear answer! I hope it does help.

Answer:

V=9021.22

Step-by-step explanation:

The formula for a cylinder is πr(r)(h)

r=13

h=17

π13(13)(17)

π169(17)

π2873

π=3.14

3.14(2873)

9021.22

V=9021.22

The table below shows the number of skateboards sold at a skate shop each week for five weeks.

w # of weeks 1 2 3 4 5

skateboards sold 22 44 66 88 110

Which equation represents the relationship between w, the number of weeks and s the number of skateboards sold?

s = 22w

s = 22/w

s = w/22

s - w = 22

Answers

Answer:

s = 22w

Step-by-step explanation:

We need to try this equation for all of the numbers in the table.

s = 22w

22 = 22 * 1

s = 22w

44 = 22 * 2

s = 22w

66 = 22 * 3

s = 22w

88 = 22 * 4

s = 22w

110 = 22 * 5

Answer:

A. s = 22w

Step-by-step explanation:

22/1 = 22

44/2 = 22

66/3 = 22

88/4 = 22

110/5 = 22
