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
Answer:
left 1 unit, up 5 units
Step-by-step explanation:
To answer the question:
<em>Which translation maps the graph of the function f(x) = x² onto the function g(x) = x² + 2x + 6?</em>
we need to find the vertex of g(x), as follows:
- x-coordinate of the vertex (h): -b/(2a) = -2/(2*1) = -1
- y-coordinate of the vertex (k): y = (-1)² + 2(-1) + 6 = 5
Therefore, g(x) can be rewritten as:
g(x) = a(x - h)² + k
g(x) = (x + 1)² + 5
which is the equation of f(x) = x² translated 1 unit to the left and 5 units up.
C=10
Here’s how you solve it!
First multiply both sides by 2
Your equation will then look like this:
3c➕46=76
Then move your constant to the other side and when you do this you also have to change the sign
3c=76-46
Then subtract 76 and 46 which is 30
3c=30
Then you divide both sides by 3
c=10
Then you are left with your answer:
c=10
