Which equation represents a quadratic function with a leading coefficient of 2 and a constant term of –3?

Step-by-step explanation:

General form. A quadratic function is of the form where ∈ R or C and ≠ .

We obtain an equation when

⇒ is an quadratic equation.

Solution.

Given, , but b is not given

Thus the quadratic function with leading coefficient and constant term is given by

∴ the required quadratic equation is

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
