Find the remainder when

1 answer:

6 0

Dividing f(x) by 2x + 5 leaves the same remainder as division by x + 5/2. By the remainder theorem, it is equal to f (-5/2), so the remainder here is

f (-5/2) = 8 (-5/2)³ + 4 (-5/2)² - 13 (-5/2) + 3 = -129/2

Rotatation could be done to left or right.

110 + 60 = 170 degrees => Rotation to the right side.

110 - 60 = 50 degrees= > Rotation to the left side.

We can see in the choices that 170 degrees is the right choice.

How can you find the number of inches in one mile

tamaranim1 [39]

You convert it to feet. There are 5,280 feet in a mile. Then convert it to inches. 5,280 feet multiplied by 12 (since there are 12 inches in a foot) is 63,360.

So... 1 mile= 5,280 feet
5,280 feet= 63,360 inches
and so
1 mile= 63,360 inches
