Answer:

5\sqrt[]{6}

Step-by-step explanation:

\sqrt[]{54}+\sqrt[]{24}

We can rewrite 54 as 6*9 and 9 can be rewritten as 3^2.

24 can be rewritten as 3*8 and 8 can be rewritten as 2^3 or 2^2*2

I'm doing this because that way I can easily take those numbers out of the square (2) root.

Let's rewrite our square roots.

\sqrt[]{6*3^2}+\sqrt[]{3*2^2*2}

3 cancels the square in the first square root, and same does 2 squared in the second square root.

3\sqrt[]{6}+2\sqrt[]{3*2}

Solve;

3\sqrt[]{6}+2\sqrt[]{6}

When you have square roots with equal value inside, you can add the numbers outside of it.

3+2(\sqrt[]{6})

5\sqrt[]{6}

Find the coordinates of the midpoint of the segment.<br> MN with endpoints M (4, 10) and N(-2,-6)
Georgia [21]

Answer:

The answer is

<h2>( 1 , 2)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M  = ( \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

M (4, 10) and N(-2,-6)

The midpoint is

M = ( \frac{4 - 2}{2}  , \:  \frac{10 - 6}{2} ) \\  = ( \frac{2}{2}  \: , \:  \frac{4}{2} )

We have the final answer as

<h3>( 1 , 2)</h3>

Hope this helps you

A 10 foot ladder is leaning up against a building. If the ladder makes a 46° angle
Gnesinka [82]

Answer:

7.193 ft

Step-by-step explanation:

    |\

    |   \

    |      \

    |         \

h  |            \      10 ft

    |               \

    |                  \

    |            46°   \

    ---------------------

For the 46° angle, h is the opposite leg. The hypotenuse is 10 ft. The sine is the trig ratio that relates the opposite leg to the hypotenuse.

sin A = opp/hyp

sin 46° = h/10

h = 10 sin 46°

h = 7.193

Answer: 7.193 ft
