Answer: ± 14

Step-by-step explanation: If x^{2} =196 then x= ±\sqrt{196}.

By taking the square root of 196, you can see that x is equal to +14 or -14.

Answer:

14

Step-by-step explanation:

<h2><u>Solve for x</u></h2>

<u />x^{2}  = 196

Find the missing lengths of the sides.
Anarel [89]

Given:

The figure of a right angle triangle.

a=b

Hypotenuse = 9\sqrt{2} in.

To find:

The missing lengths of the sides.

Solution:

In the given right angle triangle both legs a and b are equal, and hypotenuse is 9\sqrt{2} in.

Using Pythagoras theorem, we get

Hyponteuse^2=Base^2+Perpendicular^2

(9\sqrt{2})^2=(a)^2+(b)^2

81(2)=(a)^2+(a)^2                    [\because a=b]

81(2)=2(a)^2

Divide both sides by 2.

81=(a)^2

Taking square root on both sides.

\pm \sqrt{81}=a

\pm 9=a

Side cannot be negative. So,

9=a

Thus, the missing side lengths are a=9 in and b=9 in.

Therefore, the correct option is C.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Yakvenalex [24]

Answer: (C) even

<u>Step-by-step explanation:</u>

A function is even when f(x) = f(-x)

A function is odd when f(-x) = -f(x)


f(x) = -2x⁴ + 3x²

f(-x) = -2(-x)⁴ + 3(-x)²

      = -2x⁴ + 3x²

f(x) = f(-x) so the function is even


-f(x) = -(-2x⁴ + 3x²)

       = 2x⁴ - 3x²

f(-x) ≠ -f(x) so the function is not odd.

Lerok [7]
Liam will only have to pay $211 per month for health care related feed this year because the annual deductibles will only be in effect if he continues to visit his physician and chiropractor regularly. This will put the insurance company at ease that he is at his most healthy state.
