Answer:

a) 11

c) 18

d) -25

Step-by-step explanation:

Substitute: 3|-2| + 5|-1|

Absolute value is positive: 3(2)+5(1)

Simplify: 6+5

Simplify: 11

Substitute: 4|-2| +8-(-2)

Absolute value is positive: 4(2)+8-(-2)

Simplify: 8+8+2

Simplify: 18

Substitute: -3|-5|+2(-5)

Absolute value is positive: -3(5)+2(-5)

Simplify: -15-10

Simplify: -25

Answer:

$n_{tot}=44rev$

Step-by-step explanation:

In order to solve this problem we can make use of the following formula:

$\theta=(\frac{\omega_{f}+\omega_{0}}{2})t$

where θ is the total angle the basket has turned, ω is the angular velocity and t is the time.

Generally theta is written in radians and omega is written in radians per second. Now, since the revolutions are directly related to the radians and they want us to write our answer in revolutions, we can directly use the provided speeds in the formula, so we can rewrite it as:

$n=(\frac{f_{f}+f_{0}}{2})t$
