A sales team estimates that the number of new phones will sell is a function of the price that it sets. It estimates that if it sets the price at x dollars, it will sell f(x)=3,776-4x phones. Therefore, the company's revenues is x*(3776-4x).

Revenue = 3,776x-4x^2

Step-by-step explanation:

Revenue is given by = price of product * no. of units of product sold.

Given

price of 1 phone = $x

No. of phone sold = 3,776-4x

Revenue = price of 1 phone*No. of phone sold = x*(3,776-4x)

              = 3,776x-4x^2

Thus, given statement is true.

sec ф = 5/3 (quadrant 4)

let x = base

y = perp

z = hypotenuse

sec ф = hypotenuse/base = 5/3

⇒ z = 5 and x = 3

finding y:

z² = x² + y²

5² = 3² + y²

y² = 25-9

y² = 16

y = 4

now finding all other geometric functions of theta:

sin ф = y/z = 4/5

sin ф = -4/5 (sin is negative in the 4th quadrant)

cos ф = x/z = 3/5

cos ф = 3/5 (cos is positive in 4th quadrant)

tan ф = y/x = 4/3

tan ф = -4/3 (tan is negative in 4th quadrant)

cosec ф = z/y = 5/4

cosec ф = -5/4 (cosec is negative in the 4th quadrant)

cot ф = x/y = 3/4

tan ф = -3/4 (tan is negative in 4th quadrant)
