When you remove the square root You will have to remove them completely. so that the inside of the square root cannot be removed any more numbers (I'm not good at English but I hope u understand what I want u to know :)))

√32 = √2×2×2×2×2

Match 2 identical numbers one at a time and bring them out. ;

√32 = 2×2√2

√32 = 4√2 correct answer!

find you If you want to check if your square root removal is correct or not. Multiply the answer you have given by itself, for example:

4√2 × 4√2 = 16×√4 = 16×2 = 32 correct!

hope it helps you <3

Which function results in f(x)=13?

ZanzabumX [31]

Answer:

The answer is B

Step-by-step explanation:

plug 2 into x to see

x^2 + 8

2^2 + 8

4 + 8 = 12

3x^2 + 1

3(2)^2 + 1

3(4) + 1

12 + 1 = 13

2x^3 + 5

2(2)^3 + 5

2(8) + 5

16 + 5 = 21

x^2 + x

2^2 + 2

4 + 2 = 6

Built in 2011, the capital gate tower is 150 meters tall (measured vertically from the ground) and makes a 72 degree angle with

Softa [21]

Answer:

Step-by-step explanation:

You can create a right triangle out of this information and then use right triangle trig to solve.

We are given the height of the triangle as the height of the tower which is 150m.

We are given the angle of inclination as the degree the tower makes with the ground which is 72.

From the angle of 72 degrees, which is also known as the reference angle, we have the side across from it (the height) and we are looking for the side adjacent to it (how far from the base of the tower the keys will land). Side opposite the reference angle over side adjacent to the reference angle is the tangent ratio:

$tan(72)=\frac{150}{x}$ and, solving for x,

$x=\frac{150}{tan(72)}$

Make sure your calculator is in degree mode to solve this. Divide 150 by the tan(72) and find that

x = 48.7 m
