K^(-4) or 1/k^4 (Those are two different ways to write the same answer)
Answer:
6.157
Step-by-step explanation:
A=πr^2=π·14^2≈615.75216
1)
The answer is B, y=4x because the y column is always 4 times the x column
2)
Domain = (1,2)
Range = (5,6,7,8)
Function = there is no function because the x value has multiple y values associated with it
3) No
4) yes
5) Tia is correct because the y values are half of the x values
X = y * 1.07
X = cost after tax
y = item before tax added
