24% of 32k is equal to 7,680.

So she paid of $7,680 in taxes.

Answer:

4( -1 -11 )+2 (17)

-14

Step-by-step explanation:

This one requires more abstract thinking than you'd expect!

So essentially you want to count up how many -11's there are, -1's and 17's.

There are four -11's and four -1's, and two 17's.

So that means 4 x -11 + 4x-1 + 2x17 = The Total Sum of Subscribers

We can "factor out" a 4 from the -11 and -1.

4( -1 - 11) + 2(17)

So then you'd solve that and get

-14

A spin balancer rotates the wheel of a car at 500 revolutions per minute. If the diameter of the wheel is 26 inches, what road s

natta225 [31]

Answer:

c. 52 rad/s

Step-by-step explanation:

Final question does not correspond with available option. The real question is: What is the angular speed in radians per second?

At first we assume that spin balance rotates at constant rate and convert given angular speed, measured in revolutions per minute, into radians per second:

$\omega = \left(500\,\frac{rev}{min} \right)\cdot \left(2\pi\,\frac{rad}{rev} \right)\cdot \left(\frac{1}{60}\,\frac{min}{sec} \right)$

$\omega \approx 52.360\,\frac{rad}{s}$

Which corresponds to option C.

which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 – 10x 2? righ

irina1246 [14]

Answer:

$5$ units to the right and $23$ units down

Step-by-step explanation:

we have

$f(x)=x^{2}$

This is a vertical parabola open upward with vertex at point $(0,0)$

$g(x)=x^{2} -10x+2$

Step 1

Convert the function g(x) into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$g(x)-2=x^{2} -10x$

Complete the square. Remember to balance the equation by adding the same constants to each side

$g(x)-2+25=x^{2} -10x+25$

$g(x)+23=x^{2} -10x+25$

Rewrite as perfect squares

$g(x)+23=(x-5)^{2}$

$g(x)=(x-5)^{2}-23$

The function g(x) is a vertical parabola with the vertex at point $(5,-23)$

Step 2

Find the rule of the translation

$(0,0)-------> (5,-23)$

$(x,y)-------> (x+5,y-23)$

That means

The translation is $5$ units to the right and $23$ units down

A fast food restaurant was selling 7 boxes of chicken nuggets for $25.90.

mash [69]

The food with a higher unit price is chicken nuggets because when you multiply 7 and 25.90 you get 181.3. When you multiply 3 and 11.07 you get 33.21. The answer is chicken nuggets.
