Charlie is at an amusement park that has 18 different rides. Each ride costs $1.75. The function C(r) = 1.75r represents the total amount of money that Charlie will spend if he goes on r rides, but he never goes on the same one more than once. What domain and range are reasonable for the function? 1. D : 0 ≤ r ≤ 18
R : 0 ≤ C(r) ≤ 31.5

2. D : 0 ≤ r ≤ 31.5
R : 0 ≤ C(r) ≤ 18

3. D : 1 ≤ r ≤ 18
R : 1.75 ≤ C(r) ≤ 31.5

4. D : 0 ≤ r ≤ 18
R : 18 ≤ C(r) ≤ 31.5

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

yeah i know the problem you need. i am taking it right now. the answer is step 3
