Find the magnitude of the vector.<br> (-2,-7)

nevsk [136]

Answer:

$\sqrt{53}$

Step-by-step explanation:

$\begin{pmatrix}-2&-7\end{pmatrix}\\=\sqrt{\left(-2\right)^2+\left(-7\right)^2}\\\\$

Then you need to simplify:

$=\sqrt{2^2+\left(-7\right)^2}\\=\sqrt{2^2+7^2}\\=\sqrt{4+7^2}\\=\sqrt{4+49}\\=\sqrt{53}$

Solve for x. Give your answer in simplest radical form

Tasya [4]

Use the Pythagorean Theorem to find the length of the side marked "x."
x^2 + (10 mi)^2 = (13 mi)^2. Thus, x^2 + 100 mi^2 = 169 mi^2.
Next, x^2= (169-100) mi^2, or x^2 = 69 mi^2. Find the positive square root of both sides of this equation. What is it?

This is really simple i just need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Svetach [21]

It will stay the same.

$\frac{2(4)}{4} = 2$
$\frac{2(3)}{3} = 2$
$\frac{2(2)}{2} = 2$
$\frac{2(1)}{1} = 2$
No matter what you multiply 2 by, dividing it by the same number cancels it out, always leaving you with 2.
