Answer:

Step-by-step explanation:

You were close to de answer but you rounded in a wrong way

If we calculate $\sqrt{16^{2} + 14^{2}}$ we get 21.2602916255

We need to round to the nearest whole number, it means that we have we only have two options: 21 or 22

We need to remember the rounding rules:

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down

We see that 1 is followed by 2, it means that we have to round the number down, so our answer is 21

Please help!! For each sum or product, determine whether the result is a rational number or an irrational number. Then choose th

Troyanec [42]

1. Rational/The sum of two rationals is always rational
2. Irrational/ the sum of a rational and an irrational is always irrational
3. Irrational/The product of a nonzero rational and an irrational is always irrational
4. Rational/The product of two rationals is always rational

Pretty much all the irrational numbers are the ones with radical signs over them and the rational numbers are the fractions and whole numbers. Once you identify the two numbers to be rational or irrational, you can then find your answer within the second part of the answers.

If r^n=a, then which of the following are true statements? Check all that apply.

Vanyuwa [196]

A. This is correct. When you transfer n to the other side, that would be the reciprocal power of a.

b. This is incorrect, because this contradicts with choice a.

c. This is correct. When a number is raised to a "1/n" fraction, that is equivalent to the nth root of the number.

d. This is incorrect, because it is not equivalent to the given equation.

Thus, the answers are A and C.

Solve x(x-1) (X-5) <=O

lara [203]

Answer:

x <= 0 or 1 = < x <= 5.

Step-by-step explanation:

First we find the critical points:

x(x - 1)(x - 5) = 0

gives x = 0, x = 1 and x = 5.

Construct a Table of values:

x < 0 x = 0 0< x < 1 1 =< x <= 5 x = 5

x <0 0 >0 <0 0

x - 1 <0 -1 >0 <0 0

x - 5 < 0 0 > 0 <0 0

x(x-1)(x-5) < 0 0 >0 <0 0

So the answers are x =< 0 or 1 =< x <= 5.
