Answer:
Standard Form. more ... A general term meaning "written down in the way most commonly accepted" It depends on the subject: • For numbers it means "Expanded Form" (such as 125 = 100+20+5), but in Britain it means "Scientific Notation"
Step-by-step explanation:
Step-by-step explanation:
Area of the shaded region = area of the outer square - area of the inner square
= 22×22 - 15×15 sq ft
= 484 - 225 sq ft
= 259 sq ft
Answer: 8
Step-by-step explanation:
are you in elementary school
For that case, we factor the numerator and denominator:
Numerator:
We rewrite the term of the medium as a sum of two terms whose product is:
And the sum is:
+7
Those numbers are 6 and 1.
We factor the maximum common denominator of each group:
So:
Denominator:
So, we have:
Simplifying we have left:
Answer:
Option A
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
