Answer:
49
Step-by-step explanation:
So for a, the y-intercept would be positive 2 (first equation) and the slope would be 3/1. When you graph the y-intercept, which you have to do first, you can use the slope to figure out the line. The same thing would happen with the second equation. -8 is the y-intercept and -2/1 is the slope. (Negative slope would be, in this case, down 2 right 1)
Answer:
K1/K2=4
Step-by-step explanation:
The kinetic energy of a rotating sphere is given by:

The moment of inertia of a solid sphere is given by

The initial kinetic energy is therefore


The final kinetic energy is given by

Therefore the relation K1/K2 if R2 = 0.5R1

The text says nothing about the final angular velocity just the collapse of the collapse of the radius

Domain is the x and range is y so your domain is 2,3,4,5 and your range is 0 and 4
Answer
-8, -7, -2, 3, 5
Explanation
Positive numbers go up as they increase.
Negative numbers go up as they decrease.
