Since we can add up the factors of 28 (excluding 28 itself) to get
1+2+4+7+14 = 28
this means that 28 is a perfect number. In the interval from 20 to 30, it is the only perfect number.

Answer: 28

Note: Something like 22 is not a perfect number since
1+2+11 = 14
which isn't 22 like we want. Every number, in the interval from 20 to 30, but 28 has this problem.

Rewrite the exponential expression 25^3/2as a radical expression-<br> plss helpp
Agata [3.3K]

Answer:

\huge\boxed{\sqrt{25^{3}}}

Step-by-step explanation:

When we have a number to a fraction power, we need to note that

  • It's the same as taking the denominator root of the base to the numerator power

Basically, for example, 5^{\frac{1}{2}} is the same as \sqrt{5} since the numerator is 1 (5^1 = 5) and the denominator is 2 (\sqrt{5}).

Applying this same logic to 25^{\frac{3}{2}} -

25^{3}

\sqrt{25^3}

Hope this helped!

Help urgent please.
zhuklara [117]

Answer:

The answer is D


Step-by-step explanation:

Plug any x value for the y values of f(x) and g(x)

Let's do 0 since it is easier.

f(x)=-2(0)-4=-4

g(x)=-2(0)+2=2

So, g(x) is 6 greater than f(x).

Thus, g is most likely moved 6 units up from f.
