Divide the weekly amount by the number of hours worked:
75.20 / 18 = 4.177
Rounded to the nearest cent = $4.18 per hour.
The range is the ouutput from inputing the input
basically
25=k²+2k+1 and 64=k²+2k+1
the values that satisfy both equations (not at the same tim) are the valuess that are the domain
solve each
25=k²+2k+1
minus 25 both sides (or recognize the perfect square trinomial, but anyway)
0=k²+2k-24
factor
0=(k+6)(k-4)
set to zero
k+6=0
k=-6
k-4=0
k=4
k=-6 or 4
64=k²+2k+1
minus 64 both sides
0=k²+2k-63
facor
0=(k-7)(k+9)
set to zer
k-7=0
k=7
k+9=0
k=-9
k=-9 or 7
so the domain has the numbers
-9,-6,4,7
it seems we only want the positive square roots so
answer is {4,7} is the domain

Answer:
58.50
Step-by-step explanation:
First find out how many were vanilla and chocolate
vanilla: 5/6 * 36 = 30
Chocolate = total - vanilla = 36-30 =6
Cost for vanilla = 1.50*30 =45
Cost for chocolate 2.25*6 =13.5
Add the cost together
45+13.50
58.50
