Answer:

8i

Step-by-step explanation:

<em>When a quantity is raised to a fractional power, you need to root it to the power of the denominator. </em>

<em>For example, </em><em>(-64)^(1/2)  =  √(-64) </em>

<em>Since you are taking the root of a negative, you will need to put an </em><em>i</em><em> (imaginary) in your answer.</em>

Count by ones from 368 to 500. Change for a larger unit when necessary.
stepan [7]
We can figure out how many numbers there are from 368 to 500 by subtracting.

500 - 368 = 132

Now, we need to get it in word form. This can be done by looking at the place value of each number.. So your answer would be:

1 hundred, 3 tens, and 2 ones.

A car is towed using a force of 1600N. The rope used to pull the car makes an angle of 25∘ with the horizontal. Find the work do
mezya [45]

Answer: 2900185 Joules

Step-by-step explanation:

Force used to tow the car is 1600N

Angle(α)= 25

Displacement = 2km

Recall that 1km= 1000m

Therefore 2km= 2000m

Workdone= FdCos α

W= 1600 * 2000 * cos 25

W=2900184.919

W= 2900185 Nm(when approximated to the nearest integer)

Since 1J = 1Nm

Work done = 2900185 J
