26
Step-by-step explanation:
Use the Pythagorean Theorem: 
Answer:
y = -3x + 1
Step-by-step explanation:
slope = -3
y = mx + b
7 = -3(-2) + b
7 = 6 + b
1 = b
y = -3x + 1
The rates are equivalent because both of them do 30 jumping jacks a minute.

Step-by-step explanation:
Answer:
Step-by-step explanation:
1) y = (cos x) / x is neither, since cos x is even and x is odd. Expressions such as this are neither even nor odd. /
2) y = (sin x) / x is even, since sin x and x would either both be positive at the same time or negative at the same time. Recall that (-) / (-) is positive, just as (+) / (+) is positive.
