I need help with 25 please, will give brainliest and 20 points!!

The domain is the set of all integers from 0 to 14

The range is the set of all multiples of 5 between 0 and 70

Step-by-step explanation:

Domain and Range of a Function

The Domain of a Function  is the set of values the input variable x takes.

The Range of a Function  is the set of values the function takes when x moves into the function's domain.

Coach Harper can buy softballs at $5 each but he has a limit of $72 to spend on them. This situation is written as the following inequality:

5x ≤ 72

Where x is the number of softballs coach Harper can buy. Solving:

x ≤ 72/5

x ≤ 14.4

Since the number of balls must be an integer quantity and cannot be negative:

0 ≤ x ≤ 14

This means the maximum number of softballs coach Harper can buy is 14.

Thus, the domain is the set of all integers from 0 to 14

When 0 balls are bought, $0 are spent

When 1 ball is bought, $5 are spent

When 2 balls are bought, $10 are spent

Following that sequence with the maximum number of softballs:

When 14 balls are bought, $70 are spent

Note the cost can only be a multiple of 5 between 0 and 70, thus the range is the set of all multiples of 5 between 0 and 70.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
