Given:

\sqrt{2}=1.414

To find:

The value of \sqrt{50}+\sqrt{72}.

Solution:

We have,

\sqrt{50}+\sqrt{72}

It can be rewritten as

=\sqrt{2\times 25}+\sqrt{2\times 36}

=\sqrt{2}\times \sqrt{25}+\sqrt{2}\times \sqrt{36}        [\because \sqrt{ab}=\sqrt{a}\sqrt{b}]

=5\sqrt{2}+6\sqrt{2}

=11\sqrt{2}

Putting \sqrt{2}=1.414, we get

=11(1.414)

=15.554

Therefore, the value of given expression is 15.554.

The question is in the image.
miskamm [114]

Step-by-step explanation:

f(x) = 4x + 1

g(x) = x² - 5

(f+g)(x) = f(x) + g(x)

= (4x + 1) + (x² - 5)

= x² + 4x + (1 - 5)

= x² + 4x - 4

Option → C

What is the slope of these two equations?
Juli2301 [7.4K]

Answer:

8. 0

9. undefined

Step-by-step explanation:

8. 0

> because the y variable is the same for all x-values, this is a horizontal line. Horizontal lines have a slope of 0.

  > <em>Thinking of slope as rise over run: we will always rise 0, and run __ from any two points--0 divided by any number is always 0</em>

9. undefined

> because the x variable is always the same, no matter what y variable we graph, we will have the same outcome. So, this would look like a straight line, which have an undefined slope.

   > <em>If you think of a slope as rise / run; if you go from any two points, there will be a 0 in the denominator--which is undefined</em>

hope this helps!! have a lovely day :)
