Period would be the distance between 2 peaks
looking at the graph there is a peak on x= 1 and then a peak on x= 4
4-1 = 3 so the peak is 3
the amplitude is the midpoint between the highest point and lowest point
on the graph
the high point is y=1 and the low point is y = -2
1 + -3 = 3 spaces, midpoint = 3 / 2 = 1.5 so the amplitude = 1.5
the answer is the first one.
The answer is A.
if you need proof go to google and ask "is 2 irrational?"
Answer:
45
Step-by-step explanation:
As a first rough estimate: divide 390 by 10, obtaining 39.
Another reasonable approximation could be obtained by dividing 450 by 9 and 360 by 9, obtaining 50 and 40. Since 390 is roughly halfway between 360 and 450, estimate that the quotient is approx 45 (halfway between 40 and 50).
24.15
41.4 divided by 12 is 3.45
Multiply that by 7 to get your answer
