What is the slope of (0,2) and (-8,-8)?
Doss [256]

Answer: 1.25

Step-by-step explanation:

Step 1: Slope is calculated as y2 - y1/ x2 - x1

Step 2: identify the coordinates, from the stated question, y2 = -8; y1= 2

x2= -8; x1=0

Step 3: slot in the values into the formula

slope= -8 - 2/ -8 - 0

slope = -10/ -8

slope= 1.25

A 12​-tooth gear on a motor shaft drives a larger gear having 42 teeth. If the motor shaft rotates at 700 ​rpm, what is the spee
nata0808 [166]

Answer:

203 rpm

Step-by-step explanation:

The speed of the larger gear can be calculated using the following equation:

v = \omega*R  

<u>Where</u>:

ω: is the angular velocity of the motor = 700 rpm

R: is the gear ratio

The gear ratio is the following:

R = \frac{n_{(a)}}{n_{(b)}}  

<u>Where:</u>

n(a): is the number of teeth on the small gear = 12 teeth  

n(b): is the number of teeth on the larger gear = 42 teeth

The gear ratio is:

R = \frac{12}{42} = 0.29

Now, the speed of the larger gear is:

v = \omega*R = 700 rpm*0.29 = 203 rpm

Therefore, the speed of the larger gear is 203 rpm.

I hope it helps you!
