Answer:
f(2) =30
Step-by-step explanation:
f(1)=15
f(n)=f(n-1)*n
Put in n=2
f(2)=f(2-1)*2
= f(1) *2
= 15*2
=30
Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21
Answer:
12 ft
Step-by-step explanation:
If he travels 5/2 miles in 15 mins, then in 1 min he will travel 5/2 ÷ 15 = 1/6 miles and it will take him 15 ÷ 5/2 = 6 mins to travel 1 mile.
