Answer:

(x + 4)^2 + (y – 9)^2 = 25

Step-by-step explanation:

The standard form for a circle is

$(x - h)^{2} + (y - k)^{2} = r^{2}$ where (h, k) is the center and r is the radius

In your case, h = -4 and k = 9 and r = 5

So, (x + 4)^2 + (y – 9)^2 = 25

The cost to manufacture t shirts can be represented by the function c(x)=10.5x complete the following statement about the functi

Advocard [28]

For this case we have:

Cost of manufactures of T-shirts $C(x)=10.5x$

where x represents the number of T-shirts

Part A:

Substituting $x = 8$ in the total cost equation you have to:

$C (8) = (10.5) (8)\\\\C (8) = 84\\$

Thus, the cost of 8 shirts will be $C (8) = 84\\$

Part B:

If $x = 12$ then

$C (12) = (10.5) (12)\\\\C (12) = 126\\$

Thus, the cost of 12 shirts will be $C (12) = 126\\$

Answer:

$C (8) = 84\\\\C (12) = 126\\\\$
