Answer:
The value of 4 is an input of the function
Step-by-step explanation:
Let
x -----> the independent variable or input value
y ----> the dependent variable or output value
we know that
Looking at the graph
The domain (input values) of the linear function is equal to the interval
[1,∞)

All real numbers greater than or equal to 1
The range (output values) of the linear function is equal to the interval
(-∞,3]

All real numbers less than or equal to 3
therefore
The value of 4 is an input of the function
Start by multiplying 8 and 5 to get the hours worked each week.
Next multiply that by 6 to get how many hours she'll work in 6 weeks.
length = 1/2 w+9
perimeter= 60 =2(l+w)
substitute in for length
60 = 2(1/2 w +9 +w)
60 = 2 (3/2 w +9)
distribute
60 = 3w + 18
subtract 18 from each side
42 = 3w
divide by 3 on each side
14 = w
length = 1/2 w + 9
length = 1/2 (14) +9
7 + 9
16cm
Answer: 
Step-by-step explanation:
From the given picture, the radius of the base of the cylinder = 5.5 ft.
The height of the cylinder = 5 ft.+6 ft.=11 ft.
We know that the surface area of a cylinder is given by :-

Hence, the surface area of the given cylinder =
