Answer:
Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed. I don't know exactly how to interpret the rest of the question. If r is a positive rational number and p is some positive real number, then sqrt(r^2 p) / sqrt(p) is always rational, being equal r. Possibly your question refers to situtions in which sqrt(c) is not uniquely determined, as for c negative real number or complex non-real number. In those situations a discussion is necessary. Also, in general expressions the discussion is necesary, because the denominator must be different from 0, and so on.

Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given the points
Finding the slope between the points using the formula
We know that the point-slope of the line equation is
substituting and (-39,49) in the equation
Now writing the equation in slope-intercept form
where m is the slope and b is the y-intercept
∵
Where
and the y-intercept i.e.
Therefore, the equation in the slope-intercept form will be:
Hello! So, with Adian having a goal to lose 5% of his body weight, that means he will still have 95% of it left. The variable "w" represents the current amount of his weight. Multiplying by 1 will still give you his weight. Suppose he weighs 200 pounds. You plug in that as "w". Then, you would multiply that number by 5% (0.05) to see how much he would need to lose. 200 * 0.05 is 10. 200 - 10 is 190. Multiplying any number by 1 will get you to the same number. B and C are out, because they are basically the same equation, even when the "w" in answer choice C is distributed. A is out, because it shows the way the problem would be set up. D does not represent, because 1 is not his weight and it does not give a realistic answer on how much he needs to lose and weigh. Therefore, the answer is D.
Answer:
B) 194.7 m
Step-by-step explanation:
You use the radius value in the formula 2(pi)r.
2(pi)31 = 194.7
