Answer: Add 9 to both sides to complete the square

Step-by-step explanation:

The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:

(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.

(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)

How fast is the apple traveling when the kinetic energy is 32 joules?

Daniel [21]

Answer

The apple is traveling at 8 meters per second

Explanation

We have the equation that relates the kinetic energy with the velocty:

$K=\frac{v^2}{2}$

Then, to find thevelocity when the apple has 32, we replace K = 32 j:

$\begin{gathered} 32=\frac{v^2}{2} \\ 32\cdot2=v^2 \\ 64=v^2 \\ v=\sqrt{64}=8 \\ \end{gathered}$

Thus, the speed of the apple is 8meter per second

Midpoint segment plaese help shcolor in training

Paladinen [302]

Same as any other midpoint of line segment or two points, it is the average of the two points x and y coordinates...

mp=((x1+x2)/2, (y1+y2)/2)

mp=((-6+16)/2, (-9+5)/2)

mp=(10/2, -4/2)

mp=(5, -2)
