Which of the following functions is quadratic?
madam [21]

Answer:

f(x)=3(x-4)(x+3)

Step-by-step explanation:

Quadratic function follows the f(x) = ax^2 +bx+c pattern

f(x)=3(x-4)(x+3) after multiplying out is equal to

f(x)=(3x-12)(x+3) = (3x^2+9x-12x-36) = (3x^2-3x-36)

f(x) = (3x^2-3x-36)

where

a = 3

b = -3

c = -36

What is the area of the composite figure
oksano4ka [1.4K]

Answer:

C

Step-by-step explanation:

To find the area of a composite figure, separate it into the regular parts which make the irregular shape. This shape is composed of a semi-circle and a rectangle. Find the area by finding the area of each shape.

Semi-circle:

The semi-circle has a diameter of 2 + 4 + 2 = 8. The area this figure uses the radius which is half the diameter. The radius is 4. To find the area substitute r = 4 into \pi r^2 = \pi 4^2 = 16\pi. However the semi-circle has a smaller circle cut out of it with radius 2. The area of the smaller circle is \pir^2 = \pi 2^2=4\pi. The semi circle in the shape is the areas subtracted which equals 12π.

Rectangle:

The area of the rectangle is found using A = b*h = 2*5 = 10.

The total area is 12π + 10 meters squared.
