Step-by-step explanation:
In order for the whole expression to be negative, either (x⁵)
or (y⁴) or (z²) must be negative.
But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.
So (y⁴) and (z²) are always positive. The expression can be
negative if 'x' is negative, because (x⁵) will then be negative.
None of the proposed requirements is appropriate, so the
final answer is E. None .
Step-by-step explanation:
The domain of f(x) is all values of x for which f(x) is defined.
For f(x) to be defined, the expression under the radical must be non-negative.
Therefore, the domain is x ≥ 0, or in interval notation, [0, ∞).
Answer:

Step-by-step explanation:
Since the fractions have the same denominator, all we have to do is subtract the numbers in the numerator:
15 - 3 = 12
The difference of the two fractions is . To simplify this answer, divide both the numerator and the denominator by 4:
12/4 = 3
20/4 = 5
The difference in simplified form is .
I hope this helps. :)
Answer:
Anna farms apples every year with her family. One year, she harvests the apples from 4 trees. Each tree held 14 apples. How many apples did she harvest? The answer is 56 apples.
Step-by-step explanation:
The answer is 56 by the standard rules of multiplication. I personally solved it by doubling 14, then doubling the result. And we must not forget to label our answer as "apples."
