Answer:

A. -f(1/2 x)

Step-by-step explanation:

Reflextion about the x-axis is

f(x) -> -f(x)

and horizontal dilation is

f(x) -> f(-x/b) where b is the factor of dilation.

so the proper answwer is

A. -f(1/2 x)

a company has two packaging machines in a unit, each with a different daily capacity. the capacity of machine 1 is defined by th
Licemer1 [7]

The required function C (m ) which represents the combined capacity of the two machines is c(m) = 2m^2 + 104m + 1704

What are functions?

  • A connection between a collection of inputs and outputs is known as a function.

The given functions are:

f(m) = (m+40)^2 + 10 \\and\\g(m) = (m+12)^2 - 50

C(m) = f(m) + g(m)

Expanding the two square brackets in the following manner to calculate that sum:

f(m) = (m+40)^2 + 10 = m^2 + 80m + 1600 + 10 = m^2 + 80m + 1610\\g(m) = (m+12)^2 - 50 = m^2 + 24m + 144 - 50 = m^2 +24m + 94

f(m) + g(m) = 2m^2 + 104m + 1704

Therefore, function C (m ) which represents the combined capacity of the two machines is c(m) = 2m^2 + 104m + 1704

A circle in the standard (x,y) coordinate plane has
Otrada [13]

Given:

Center of a circle is at point C(-1,2).

AB is the diameter of the circle.

Coordinates of the point A are A(2,6).

To find:

The coordinates of point B.

Solution:

Let the coordinates of point B are (a,b).

If AB is the diameter of the circle, then A and B are end points of diameter of the circle and the center C is the midpoint of AB.

Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

Point C = Midpoint of AB

(-1,2)=\left(\dfrac{2+a}{2},\dfrac{6+b}{2}\right)

On comparing both sides, we get

\dfrac{2+a}{2}=-1

2+a=-1\times 2

a=-2-2

a=-4

Similarly,

\dfrac{6+b}{2}=2

6+b=2\times 2

b=4-6

b=-2

Therefore, the coordinates of point B are (-4,-2).
