The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x²+180x . The cost, in dol
tresset_1 [31]

We use the profit concept, and doing this, it is found that if 150 televisions are sold, the profit is $50,700.

-------------------------------------------

Profit is given by revenue subtracted by cost.

In this question:

  • Revenue: R(x) = 3x^2 + 180x
  • Cost: C(x) = 3x^2 - 160x + 300

Thus, the profit of selling x televisions is:

P(x) = R(x) - C(x)

P(x) = 3x^2 + 180x - (3x^2 - 160x + 300)

P(x) = 3x^2 + 180x - 3x^2 + 160x - 300

P(x) = 340x - 300

-------------------------------------------

For 150 televisions, we have P(150), so:

P(150) = 340(150) - 300 = 50700

If 150 televisions are sold, the profit is $50,700.

A cylindrical plastic pipe’s length is 12 cm and it’s radius is 2.5 cm. To the nearest tenth, what is the volume of the pipe?
NemiM [27]

Answer:

V = 235.6 cm³

Step-by-step explanation:

the formula for the volume of a cylinder of radius r and length h is

V = πr²h.  

Here, r = 2.5 cm and h = 12 cm, so the volume is:

V = π(2.5 cm)²(12 cm) = 75π cm³

To the nearest tenth, this volume would be V = 235.6 cm³
