P(x)=f(x)*g(x)
P(x)=(x-400)(1,200-2x)
P(x)=1,200x-2x^2-480,000+800x
P(x)=-2x^2+2,000x-480,000

Answer: Option <span>D. P(x) = -2x2 + 2,000x - 480,000</span>

Answer:

Option (D) is correct.

P(x)=-2x^2+2000x-480000

Step-by-step explanation:

Given : The number of units produced in May is given by function f(x) = x-400

and the manufacturer's profit per unit for May is given by the function g(x) = 1200-2x

We have  to determine the  total profit the manufacturer can earn in May, P(x).

Consider the given data

Since,   The number of units produced in May is given by function f(x) = x-400

and the manufacturer's profit per unit for May is given by the function g(x) = 1200-2x

Total profit that the manufacturer can earn in May is given by the product of number of units produced with the profit per unit.

that P(x)=F(x)\cdot G(x)

Substitute the values, we get,

P(x)=(x-400)\cdot(1200-2x)

Simplify, using FOIL method \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd

=x\cdot \:1200+x\left(-2x\right)+\left(-400\right)\cdot \:1200+\left(-400\right)\left(-2x\right)

We get,

P(x)=-2x^2+2000x-480000

Thus, Option (D) is correct.

rjkz [21]

Answer:

84 cm²

Step-by-step explanation:

Surface area of the polyhedron = the sum of the areas of each parts of the net = area of 2 triangles + area of each of the 3 rectangles

Area of 2 triangles:

Base = 4 cm

Height = 3 cm

Area of the 2 triangles = 2(½*base*height)

= 2(½*4*3) = 4*3 = 12 cm²

Area of rectangle with the following dimensions:

Length = 6 cm

Width = 4 cm

Area = length * width = 24 cm²

Area of rectangle with the following dimensions:

Length = 6 cm

Width = 5 cm

Area = length * width = 30 cm²

Area of rectangle with the following dimensions:

Length = 6 cm

Width = 3 cm

Area = length * width = 18 cm²

Surface area of the polyhedron = 12 + 24 + 30 + 18 = 84 cm²

The diagram below shows part of the graph of the quadratic function f(x)=a(x-h)(x-k) with the condition h&lt;k. Point P is the m
Valentin [98]

Answer:

see explanation

Step-by-step explanation:

(a)

The zeros are x = 1 and x = 5, thus the factors are (x - 1) and (x - 5)

f(x) = a(x - 1)(x - 5)

To find a substitute (0, 15), the coordinates of the y- intercept into the equation.

15 = a(0 - 1)(0 - 5) = a(- 1)(- 5) = 5a ( divide both sides by 5)

a = 3

Thus h = 1, k = 5, a = 3 and

f(x) = 3(x - 1)(x - 5)

(b)

The axis of symmetry is a vertical line with equation x = c ( c is a constant )

The axis of symmetry passes through the midpoint of the zeros

x = \frac{1+5}{2} = \frac{6}{2} = 3

Equation of axis of symmetry is x = 3

(c)

The axis of symmetry passes through P, with x- coordinate x = 3

Substitute x = 3 into the function for corresponding value of y

f(3) = 3(3 - 1)(3 - 5) = 3(2)(- 2) = - 12

Coordinates of  P = (3, - 12 )
