Find the distance between each pair of points. Round your answer to the nearest tenth if necessary
vodka [1.7K]
Answer is 5.4 units

Step by step.
I used Pythagorean theorem to find the diagonal (hypotenuse) of the triangle.
We know the height (y) is 5 and the other leg (x) is 2.

a^2 + b^2 = c^2 is the formula.
Substitute the two legs in for a and b.

5^2 + 2^2 = c^2
29 = c^2

Now take the square root of both sides
5.385 = c

Round to nearest tenth = 5.4 units

Hi! I've tried this problem a couple times but am still stumped :( Can you help?!
aniked [119]

ANSWER:

X\text{ = }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix}

EXPLANATION:

Given:

U\text{ = }\begin{bmatrix}{1} & {3} & {-5} \\ {2} & {14} & {11} \\ {-8} & {0} & {5}\end{bmatrix}\text{           V =}\begin{bmatrix}{13} & {1} & {-7} \\ {-6} & {1} & {9} \\ {0} & {15} & {23}\end{bmatrix}

Since U and V are Matrices with equal dimensions(3 x 3 matrix), and

X + U = V.

To solve for X, we have:

X = V - U

\begin{gathered} X\text{ = V - U} \\ X\text{ = }\begin{bmatrix}{13-1} & {-1-3} & {-7-(-5)} \\ {-6-2} & {1-14} & {19-11} \\ {0-(-8)} & {15-0} & {23-5}\end{bmatrix}=\text{ }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix} \end{gathered}X\text{ = }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix}
