Answer:

19.2873015 (Done by a calculator) <---- could be wrong

Step-by-step explanation:

And fun fact:

Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not perfect square are members of irrational numbers. This means that they can't be written as the quotient of two integers.

Hope it helps!

Answer:

No real solution

Step-by-step explanation:

you cannot take the square root of a negative number, because a negative times a negative is always a positive. (In later math, you will learn there are imaginary numbers which can be the square roots of negative numbers, but that's way in the future of math classes.)

Answer:

$\sin(x) = \frac{opposite \: side}{hypotenuse}$

$\cos(x) = \frac{adjacent}{hypotenuse}$

$\tan(x) = \frac{opposite \: side}{adjacent \: side}$

Answer: Equation Classification : A. Possible and Determined;

B. Possible and undetermined and C. Impossible:

Step-by-step explanation:

A. Possible and Determined: These are equations that admit at least one solution.

Example: 2x = 3 → x = <u>3 </u>

B. Possible and undetermined:

They are equations that have infinite solutions.

Example: x + 2 = x + 2 → The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.

C. Impossible: Has no solution.

Examples:

0x = 4 → Unable to divide 4 by 0.

y = y + 2 → y - y = + 2 → 0 = +2 → There is no equation without unknown.

Answer:

the correlation coefficient of the line of best fit is, 0.98247.

Step-by-step explanation:

Correlation Coefficient are used to find how strong relationship between the data. It expressed its values between +1 and -1. It is represented by r.

* if 0<r<1 indicates a strong positive relationship.

* -1<r <0 indicates a strong negative relationship.

* r=0 indicates no relationship at all.

The formula for this :

$r = \frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2-(\sum x)^2][n\sum y^2-(\sum y)^2]}}$
