Answers

Answer:

Chubby ran a distance of 6,283 m

Step-by-step explanation:

The length of one run is simply equal to the circumference of the circle

Mathematically, C = pi * d

C = 22/7 * 20 = 62.83 cm

So if one rotation is a distance of 62.83 cm, then 100 rotations will be a distance of;

62.83 * 100 = 6,283 m

What is the range and domain of a function?

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

Given a number line with arrows.

If a number is included then it is given in the middle bracket [ ] while if it is not included then it is given in the small bracket ().

Since in the given number line,

The line is coming through -∞ and at 2 not up to

So,

(-∞,-2) will be correct.

Now,

The right-hand sideline is going from 2 to 5(not included)

So,

[2,5) will be correct.

Hence "(-∞,-2) and [2,5) will be the correct representation of the given number line".

the rileys are replacing the carpet on their outdoor deck. the deck is a regular hexagon with radius 9ft. the cost for the carpet and installation is $3.75/ft^2. what will it cost to replace the carpet? Have to show work on how i got the answer

Answers

Hexagon radius = side = r =9 ft.

Hexagon Area = (3√3)/2 * r²

∴ Area = (3√3)/2 * 9² ≈ 210.444 ft²

The cost for the carpet and installation is $3.75/ft²

∴ The total cost = Area * cost per ft²
= 210.444 * 3.75
= $ 789.166
