3/8 divided by 1/4
hope this helped
The vertex form is y=a(x-h)²+k
the vertex is (h,k)
so
y=-1(x-2)²+3
compare to
y=a(x-h)²+k
2=h and 3=k
the vertex is (2,3)

The number of days d, he must use the gym to make the membership worthwhile is at least 21 days
Equation
Non members:
Cost of swimming per day = $5
Cost of exercise per day = $9
Total = $5 + $9
= $14
Members:
Yearly fee = $300
Exercise fee per day = $4
Swimming fee = $0
The number of days d, he must use the gym to make the membership worthwhile = $300 ÷ 14
= 21.42857142857142
Approximately,
21 days

Answer:
x=-0.544727
x=2.294727
Step-by-step explanation:
Given quadratic equation to solve:
To solve, use the quadratic formula
x= -b ± b² - 4ac / 2a
Substitute your values for a, b, & c and solve
x= -7 ± 7² - 4·(-4)·5 / 2·(-4)
x= -7 ± 49 - -80/-8
x= -7 ± 129/-8
Then, reduce the problem
x= -7/-8 ± 129/-8
x=-0.544727
x=2.294727
