Jet001 [13]

Answer:

the profit will be $172

Step-by-step explanation:

The function given is:

p(x) = 2(x-9)^2 + 100

Where x is the price of the each shirt.

if each shirt is sold for $15,  hen x = 15.

the profit will be:

p(15) = 2(15-9)^2 + 100

p(15) = 2(6)^2 + 100

p(15) = 2(36) + 100

p(15) = 72 + 100

p(15) = 172

So, the profit will be $172

Quadrilateral DXHW∼quadrilateral LSCT
Alex777 [14]

Answer:

HW → CT

∠ X → ∠ S

∠ D → ∠ L

DW → LT

Step-by-step explanation:

The quadrilateral DXHW is similar to quadrilateral LSCT.

So, side HW of the quadrilateral DXHW matches with the CT side of the quadrilateral LSCT.

And angle ∠ X of the quadrilateral DXHW matches with the angle ∠ S of the quadrilateral LSCT.

Again, angle ∠ D of the quadrilateral DXHW matches with the angle ∠ L of the quadrilateral LSCT.

Finally, side DW of the quadrilateral DXHW matches with the LT side of the quadrilateral LSCT. (Answer)
