What number must you add to the expression below to complete the square? x^2-20x?

1 answer:

5 0

We have that
x²<span>-20x
</span><span>Group terms that contain the same variable
</span>(x²-20x)
Complete the square
(x²-20x+10²)------> (x-10)²

the answer is
the number must be 100

Help Link (little green guy on the left) defeat Ganon and save Zelda. Find the distance from Link to the Green Soldier so Link c

kenny6666 [7]

Answer:

5 Units.

Step-by-step explanation:

In the attached diagram, Link is at (0,1) and Ganon is at (4,4)

To find the distance between the two, we use the distance formula $Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$(x_1,y_1)=(0,1), (x_2,y_2)=(4,4)$

Distance between Link and Ganon $=\sqrt{(4-0)^2+(4-1)^2}$

$=\sqrt{4^2+3^2}\\=\sqrt{16+9}\\=\sqrt{25}$

=5 Units

The distance between the two is 5 Units.

Give the radian measure of an angle drawn in standard position that corresponds with the ray containing the coordinate point (−1

Sergeu [11.5K]

Answer:

The radian measure of the angle drawn in standard position that corresponds with the ray containing the coordinate point $(-12, -3\sqrt{2})$ is approximately $1.108\pi$ radians.

Step-by-step explanation:

With respect to origin, the coordinate point belongs to the third quadrant, which comprises the family of angles from $\pi\,rad$ to $\frac{3\pi}{2}\,rad$ . The angle in standard position can be estimated by using the following equivalence:

$\theta = \pi\,rad + \tan^{-1} \left(\frac{3\sqrt{2}}{12} \right)$

$\theta \approx \pi \,rad + 0.108\pi \,rad$

$\theta \approx 1.108\pi\,rad$

The radian measure of the angle drawn in standard position that corresponds with the ray containing the coordinate point $(-12, -3\sqrt{2})$ is approximately $1.108\pi$ radians.
