Answer:
Step-by-step explanation:
x + x + 10 + 3x = 180
5x + 10 = 170
5x = 170
x = 36°
3(36)= 108° the largest angle
36.4/(312312*1.065)
36.4/332612.28=0.00 (2dp)
If you meant 312
36.4/(312*1.065)
36.4/332.28=0.10 (2dp)
Hope this helps :)
(480 - 400) / 400 = 80 / 400 = .2 * 100 = 20%.
480 + .10 * 480 = 480 + 48 = 528
(528 - 480) / 480 = .1 * 100 = 10%
(x - 480) / 480 = .10
x/480 - 480/480 = .10
x/480 - 1 = .10
x/480 = 1.10
x = 1.10 * 480
= 528
Answer:
See below
Step-by-step explanation:
1. During which time period is Kelly's heart rate increasing? (1 point)
2. Using math, determine the exact rate of change for the increase (warm‐up). Explain how you got your answer. (3 points; 1 point for answering the question, 2 points for explaining your answer)
-
Rate of change = Change in y / change in x
- (115 - 65)/(15-0) = 50/15 = 3.33
3. During which time period did Kelly's heart rate remain constant? (1 point)
4. Using math, determine the exact rate of change for this time period. Explain how you got your answer. (3 points; 1 point for answering the question, 2 points for explaining your answer)
-
ROC = (115 - 115)/(35 - 15) = 0
5. During which time period did Kelly's heart rate decrease? (1 point)
6. Using math, determine the exact rate of change for the decrease (cool down). Explain how you got your answer. (3 points; 1 point for answering the question, 2 points for explaining your answer)
-
ROC = (70 - 115)/(45 - 35) = - 45/10 = -4.5
7. Explain why your rate of change for the cool down period was a negative value. (2 points)
- Negative rate indicates drop in heart rate during cool down
The correct answer is number 3.
