Answer:
Domain = 1 to 7
Range = 4 to 28
Step-by-step explanation:
Given that:
Number of wheels used is a function of number of cars manufactured.
Number of wheels present = 28
1 car uses 4 wheels
2 cars use 8 wheels.
3 car uses 12 wheels
and so on.
Let the function be of the form:
Domain of the function is the value of 
that can be given as valid input to the function.
Range of the function is the value of 
that can be output of the function.
Let be the number of cars manufactured.
Then value of is nothing but times 4.
We are given that maximum value of can be 28.
Therefore, maximum value of input can be 7.
Minimum number of wheels can be 4 to make a minimum of 1 car.
Therefore domain is 4 to 28 and range is 1 to 7.
Find area
area=pir^2
d/2=r=50/2=25
A=pi25^2
a=pi625
aprox pi=3.141592
a=1963.495
that is how many square feet
multiply that by 120
1963.495 times 120=$235,619.4
Answer:
Uh that's great- you missed something I'm sure
Step-by-step explanation:
So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4. So she's 75% of the time effective.
Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.
Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.
so, which fraction is highest 3/4, or 2/3 or 2/3? neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.
so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.
notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
