Yeah youre good because
.80 times 14 is 11.2
The period is the distance between one peak and the next peak ( the two highest points)
One peak is at x= 0, the next peak is at x = 5 then the third peak is at x = 10.
Subtract to find the distance: 10-5 = 5 and 5-0 = 5 so the period is 5.
The amplitude is the distance from the centerline to the peak. First find the highest and lowest points to finch the center:
Highest = 3 lowest = -2. The distance between the highest and lowest is 5 so the centerline would be 5/2 = 2.5
The amplitude would be the distance from center to peak which would be 2.5
The answer is:
Period = 5, amplitude = 2.5
Answer:
slope = 1
Step-by-step explanation:
slope = (y2 - y1)/( x2-x1)
slope = -2-3/-3-2
slope = -5/-5
slope = 1
1. write the division as a fraction
9+n/2>16 → 9+1/2n>16
2. multiply both sides of the inequality by 2
2x9+2x1/2n>2x16
3. multiply the numbers and reduce the numbers with greatest common divisor 2 (remove number 2, the common factor from equation)
18+n>32
4. move constant to the right by adding its opposite to both sides
18+n-18>32-18
5. eliminate the opposites
n>32-18
6. subtract the numbers
n>14
hope this helped!
