Answer:
x = -9
Step-by-step explanation:
3×( -3 ) + 4 gives -9 + 4 = 5 hence proved
Z=yn
divide both sides by n to get y by itself
Z/n=yn/n
Cross out n and n, divide by n
Then becomes 1*1*y=y
Answer:
y=Z/n
Answer:
The cost of printing 142 more posters when 18 has already been printed is $5.57.
Step-by-step explanation:
We are given that the marginal cost (dollars) of printing a poster when x posters have been printed is given by the following equation C'(x)=x^-3/4.
The given equation is:
The cost of printing 142 more posters when 18 have already been printed is given by;
Integrating both sides of the equation and using the limits we get;
As we know that , so;
=
=
=
=
= $5.57
Hence, the cost of printing 142 more posters when 18 has already been printed is $5.57.
