The central 50 percent of data around average
Answer:
b) 3w² = 243
Step-by-step explanation:
area = L x w
L = 3w
substitute for L:
243 = 3w x w = 3w²
3w² = 243
F(x) = -4x - 5
Subtitute the value of x to the equation:
f(-1) = -4 · (-1) - 5 = 4 - 5 = -1
Answer: 77.31°
explanation: you’ll have to round it on your own it confuses me
Answer:
See below
Step-by-step explanation:
<u>Question 7</u>
- The rate of change in Health Club A is 12 as given in slope-intercept form
- The rate of change in Health Club B is 21 as given by an increase of $21 per month
- The rate of change in Health Club C is 15 as given by (70-40)/(3-1)=15
- The rate of change in Health Club D is 20 as given by "$20 each month for x months"
- Therefore, Health Club B has the greatest rate of change of $21 per month
<u>Question 8:</u>
- The initial value of Health Club A is 60 as given in slope-intercept form
- The initial value of Health Club B is 0 as given by $0 for 0 months
- The initial value of Health Club C is 25 as given by y=mx+b --> 40=15(1)+b --> b=25
- The initial value of Health Club D is 20 as given by "A customer pays a one-time fee of $20"
- Therefore, Health Club A has the greatest initial value (or y-intercept) of $60
