Answer:

$\boxed {\tt 9^{5}}$

Step-by-step explanation:

When multiplying exponents, the base stays the same and the exponents are added.

$a^x*a^y=a^{x+y}$

We are given the expression:

$9^2*9^3$

The base is 9, and it will stay the same. The exponents, 2 and 3, must be added.

Exponents: 2, 3
Add them: 2+3=5

$9^{2+3}$

$9^5$

The answer to 9²*9³ is 9⁵

When a figure is translated on a coordinate grid, what conclusion can you draw from the pre-image and image?

Ilia_Sergeevich [38]

Answer:

The side lengths remain the same, and the position of the figure changes.

Step-by-step explanation:

A translation is a slide of a figure. A figure can be slid vertically, horizontally or diagonally.

Think of sliding a game board across a table. The lengths of the sides of the board do not change; the angles formed by the sides of the board do not change; and the way the board is turned does not change. This means the only correct option would be the last one.

A car tire with a radius of 16inches is turning at a rate of 120 revolutions per minute. Find the exact linear speed of the tire

anygoal [31]

Answer:

The speed of the tyre of the car is 1002.24 feet per minute .

Step-by-step explanation:

Given as :

The radius of the car wheel = r = 16 inches

Since 12 inches = 1 feet

So, 16 inches = $\frac{1}{12}$ ×16 = 1.33 feet

The number of revolution of the wheel = 120 revolution per minute

Let The speed of the wheel = s feet per minute

The circumference of wheel = 2 × $\pi$ × radius

where $\pi$ = 3.14

or, circumference = 2 × 3.14 × 1.33

Or, Circumference = 8.352 feet

Now , Speed = circumference of wheel × number of revolution

or, Speed = 8.352 feet × 120 revolution per minute

∴ Speed = 1002.24 feet per minute

Hence The speed of the tyre of the car is 1002.24 feet per minute . Answer
