Answer:

Wheel1 = 147inches , wheel 2 = 113inches

Wheel 1 will travel 147 revolutions.

Step-by-step explanation:

Finding the circumference of both wheels

Wheel 1 = 2 pi r = 2 × 3.142 × 23.4 = 147.05 inches. To the nearest inches = 147inches

Wheel 2 = 2 pi × r = 2 × 3.142 × 18 = 113.11inches . To the nearest inches = 113inches.

I rotation = 1 revolution

In 1 rotation, wheel 1 will travel= 147 × 1 = 147 revolutions.

Answer:

16 inch

Step-by-step explanation:

Wheel I has diameter 23.4.

Wheel ll has diameter 18.0

  • Diameter of Wheel 1 to the nearest inch = 23 inch
  • Diameter of Wheel 2 to the nearest inch = 18 inch

The distance which each wheel will travel is determined by the circumference of the wheel.

Circumference of a Circle =\pi d

Distance Traveled by Wheel 1 in One Rotation =23\pi

Distance Traveled by Wheel 2 in One Rotation =18\pi

Therefore, the distance which Wheel 1 travels further =23\pi-18\pi=5\pi =15.7 inch

The distance farther is 16 inch to the nearest inch.

For f(x) = x3 – x2, which gives an output of 48?<br> O f(-8)<br> O fl-4)<br> O f(4)<br> O f(8)
Misha Larkins [42]

Answer:

f(4)

Step-by-step explanation:

The output is the value of f(x) for a given value of x ( the input )

Substitute the given values of x into f(x) to determine the output, that is

f(- 8) = (- 8)³ - (- 8)² = - 512 - 64 = - 576 ≠ 48

f(- 4) = (- 4)³ - (- 4)² = - 64 - 16 = - 80 ≠ 48

f(4) = 4³ - 4² = 64 - 16 = 48

Thus f(4) gives an output of 48
