Mathematics
1 answer:
Wewaii [24]3 years ago
8 0

For this case we have a function of the form y = f (x), where:

f (x) = - x ^ 2 + 1

We must evaluate the function for x = -3

Then we have to replace:

f (-3) = - (- 3) ^ 2 + 1\\f (-3) = - 9 + 1

Different signs are subtracted and the sign of the major is placed:

f (-3) = - 8

ANswer:

f (-3) = - 8

A truck with 36-in.-diameter wheels is traveling at 55 mi/h.
bagirrra123 [75]

Answer:

The wheels make 512 revolutions per minute

Step-by-step explanation:

Diameter of truck = 36 in

Speed = 55 mi/h

Revolutions per minute =?

Radius r = diameter / 2

r = 36/2

r = 18 inches

Speed = 55 mi/h

1 mile = 63360 inches

55 miles = 55*63360 inches

55 miles = 3484800 inches

1 hr = 60 minutes

Speed = 3484800 inches/60 minutes

Speed = 58,080 inches/min

The formula used to calculate the revolutions per minute is:

revolutions = speed/Circumference

revolutions = 58,080 / 2*3.14*18

revolutions = 58,080 /113.4

revolutions = 512.16

revolutions = 512 revolutions per minute

So, The wheels make 512 revolutions per minute
