Answer:

Option A

Step-by-step explanation:

The domain of a function is the set of all numbers that has an image in the co domain. It means that those elements are mapped to other elements and give output values.

From the figure we see that all the elements in $x$ are marked to other elements in $f(x)$ . So, the domain would be:

$\{-4, -1, 0, 2, 7\}$

Hence, Option A.

the area of a rectangular volleyball court is 1800 square feet the courts length is twice it width write a system of equations t

Marianna [84]

Answer:

The dimensions of the rectangular volleyball court are 60 ft x 30 ft

Step-by-step explanation:

Let

x ----> the length of rectangular volleyball court

y ---> the width of the rectangular volleyball court

we know that

The area of the rectangular volleyball court is equal to

$A=xy$

$A=1,800\ ft^2$

$1,800=xy$ ----> equation A

$x=2y$ -----> equation B

substitute equation B in equation A

$1,800=(2y)y$

$1,800=2y^2$

Solve for y

Simplify

$900=y^2$

take square root both sides

$y=30\ ft$

<em>Find the value of x</em>

$x=2y$

substitute the value of y

$x=2(30)=60\ ft$

therefore

The dimensions of the rectangular volleyball court are 60 ft x 30 ft

What are the real or imaginary solutions of the polynomial x^4-3x^2=-2x

bagirrra123 [75]

Answer:

x = 0 or 1 or -2

x(x^3-3x+2)=0

x(x-1)^2 * (x+2)0

so x = 0 or 1 or -2

there is no imaginary solutions

If angle p is right angle and angle p and angle q are supplementary then what is angle q

Schach [20]

Right angle (angle p) = 90°
supplementary means total equals 180°
so 90° + q = 180°
subtract 90° from both sides
q = 90°
