Answer:

-10

Step-by-step explanation:

So first you would locate -8 on the number line. (It's to the left of 0.) Then you subtract 2. This means you are basically going left 2 places.

(-8)-2=-10

By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.

That gives us point (3,5) as the top of the parabola. So there you go, answer A.

An accountant gets paid $150 for each tax return she prepares and her goal is to earn $6,750 preparing tax returns during this t
kolbaska11 [484]

Answer: 42

Step-by-step explanation:

First you have to subtract 450 from 6750 to get 6300

Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450

Third you have to do 6300 / 42 to get 150 so if you times 150x 42 equals 6300.

First find the area of the rectangle  by multiplying the length and width of the rectangle, so 12 x25=300. Then find the area of the triangle, which is length x height/ 2. So 8 x 25=200/2=100. Then add the two answers together to get 400.

If A(3,4) and B(10,4) are the end points of a diameter of circle "O", what is the area of the circle O
ikadub [295]

Answer:

\large\boxed{\dfrac{49\pi}{4}}

Step-by-step explanation:

The formula of an area of a circle:

A=\pi r^2

<em>r</em> - radius

We have the endpoints of a diameter of a circle.

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substitute the coordinates of the given points A(3, 4) and B(10, 4):

d=\sqrt{(10-3)^2+(4-4)^2}=\sqrt{7^2+0^2}=\sqrt{7^2}=7

Therefore we have the length of the diameter: <em>d = 7</em>

We know: <em>d = 2r.</em> Therefore

r=\dfrac{7}{2}

Substitute to the formula of an area:

A=\pi\left(\dfrac{7}{2}\right)^2=\dfrac{49\pi}{4}

<em>There is no such answer in the answers to choose.</em>

<em>Apparently you have some error in the coordinates of the endpoints.</em>
