Answer:

355

Step-by-step explanation:

3 $x^{3}$ -5 $y^{2}$ =3*5³-5*2²

3*5³-5*2²=3*125-5*4

3*125-5*4=375-20

375-20=355

If X = 13 units, Y = 12 units, and Z = 15 units, what is the volume of the rectangular prism shown above?

Basile [38]

Volume of the Rectangular prism is 2340 square units

Step-by-step explanation:

Given:

X = 13 units,

Y = 12 units,

Z = 15

To Find:

The volume of the rectangular prism = ?

Solution:

The volume of the rectangular prism = $X \times Y \times Z$

On substituting the values,

Volume of the Rectangular prism = $13 \times 12 \times 15$

Volume of the Rectangular prism = 2340 square units

A water wheel has a radius of 4 feet and the bottom of the wheel is 1 foot from the ground. one plank is painted white and it st

Sliva [168]

The correct option is 9 feet.

The height from the ground the white plank after the motion is 9 feet.

<h3>What is rotational motion?</h3>

Anything that spins or moves in a circular route is said to be in rotational motion. It's also referred to as angular motion and circular motion. The motion can be uniform (— in other words, the velocity v remains constant) and non-uniform, but it must be circular.

Now, according to the question;

The wheel's radius is 4 feet.

The height of a bottom of a wheel from the ground equals 1 foot.

π/3 radians is the angle where the wheel is rolled.

The following relationship describes the height of a revolving wheel.

f(t) = A·sin(B·t + C) + D

Where,

D = Mid line = 4 + 1 = 5 feet

B·t = π/3

C = 0

amplitude; A = 4

Substituting the values in the function;
