Answer:
2.5
Step-by-step explanation:
The amplitude of a function is the amount by which the graph of the function travels above and below its midline.
The distance from the highest most point to the lowest point vertically is 5, meaning that the midpoint is 2.5 units from either end.
90 seconds = 1.5 minutes
1.5 minutes = 28 revolutions
Revolutions in 1 minute = 28/1.5 = 18.67 revolutions
Revolutions in 4 minutes = 18.67*4
= 74.7 (approx.) revolutions
Answer:(-5,1)
Step-by-step explanation:! X= -3 so -3-4= -7, Y= 7 so 7+2=9, So the coordinates will be (-7,9) I hope that I could help you
Answer:
73.5?
Step-by-step explanation:
I don't know this for sure, but if 7 equals 2 * 3 + 1 (half of one) then if x were the equal 21, then it would be 21 * 3.5, which equals 73.5.
UNLESS, OF COURSE Y isn't 3.5 * x, and is rather five plus X
