The answer is A.

A negative x a negative equals a positive so the square root of a negative value cannot be a negative value.

14 (OM) Radicals and Estimation (2 pts) Without a calculator, estimate the radical and explain how you estimated. Then using a c
Irina-Kira [14]

Q) Without a calculator, we must estimate the value of the following expression:

3-\sqrt[]{38}.

A) I estimate 3 - √38 to be approximately -3.2.

First, we estimate the value of √38. √38 is between √36 and √49, but close to √36 (since 38 is closer to 4 than it is to 9). Since √36 is 6, √38 is probably something like 6.1 or 6.2. Filling 6.2 in the expression and simplifying, we have this:

3-6.2=-3.2.

So, I expect the number 3 - √38 to be close to -3.2.

Using a calculator we find that: 3 - √38 ≅ -3.16, which it is approximately the result that we found.

Answer

Without a calculator we find that 3 - √38 ≅ -3.2.

I literally have no clue how to do this.
timurjin [86]

Answer:

Step-by-step explanation:

Sine is opposite divided by the hypotenuse.

sin(30) = 9/y

1/2 = 9/y

y = 18

Cosine is adjacent divided by the hypotenuse

cos(30) = x/18

\frac{\sqrt{3} }{2}=x/18\\x=9\sqrt{3}=15.6

Whats the radical of 12?
Harrizon [31]

Answer:

2√3

Step-by-step explanation:

So √12 is in radical form. I think what you are asking for is to reduce the expression to its **simplest** readical form.

So 12 = 4*3, √12 = √4 * √3.

So 12 = 4*3, √12 = √4 * √3.

We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.

This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.

Answer: 12.2474487139

Step-by-step explanation:

(I think what you wrote is just the square root of 150? if I read this wrong please let me know so I can correct my answer.)

*If you plug in the square root of 150 into a calculator, you get 12.2474487139
