We factor the equation to get:
-(x-25)^2+361
In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361). This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.
B. The x-intercepts are the values of x for which f(x) is 0. This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44. Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.
Answer:
C -1
Step-by-step explanation:
Hello.
To find the diameter you use this equation:
Radias<span>cm x 2/pie
</span>
So it would be 124=π*d
d=124/π
So the answer would be :
d=39.47=39.4 feet
Have a nice day
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
