Solving the expression $\frac{5^{-2}5^3}{5^{-1}}$ we get 25

Step-by-step explanation:

We need to rewrite the expression $\frac{5^{-2}5^3}{5^{-1}}$ without exponents

Solving:

$\frac{5^{-2}5^3}{5^{-1}}$

Using exponent rule: $a^{-1}=\frac{1}{a}$

$=\frac{5^3}{5^{-1+2}}$

$=\frac{5^3}{5^{+1}}$

$=\frac{125}{5}$

$=25$

So Solving the expression $\frac{5^{-2}5^3}{5^{-1}}$ we get 25

PLS ANSWER ASAP FIRST ONE TO DO SO GETS BRAINLIEST

Answer:

Carmen can make $10\frac{5}{16}$ full servings.

Step-by-step explanation:

Given : Carmen mixes $3\frac{1}{2}$ cups of water with $3\frac{3}{8}$ cups of juice to make punch.

Total quantity of punch Carmen made = total cup of water + cup of juice she mixes

Total quantity of punch Carmen made = $3\frac{1}{2}+3\frac{3}{8}$

Solving , we get,

Total quantity of punch Carmen made = $\frac{7}{2}+\frac{27}{8}$

taking LCM(2,8) = 8 , we get,

Total quantity of punch Carmen made = $\frac{28+27}{8}=\frac{55}{8}$

Also, given She pours $\frac{2}{3}$ cup servings of punch.

Thus, $\frac{2}{3}$ cup of mixture makes 1 serving cup.

Using unitary method,

In unitary method we first find the value of a single quantity and then multiply it with the desired quantity.

1 cup of mixture makes $\frac{3}{2}$ serving cup.

$\frac{55}{8}$ cup makes = $\frac{3}{2}\times\frac{55}{8}$

$\frac{55}{8}$ cup makes = $\frac{165}{16}=10\frac{5}{16}$

Thus, She can make $10\frac{5}{16}$ full servings.

All i need to know is if its a function or not (I will give branliest for a good explanation)

tankabanditka [31]

Answer:

It's fine. It is a function. The language can be very convoluted. Put simply a domain value cannot have 2 different range values.

Step-by-step explanation:

The confusing part I think, is probably the fact that -1 and 1 both have an answer of 5.

That's fine. Parabolas do that and they are functions. Two different xs can have the same value. The thing that eliminates functions is when the x value (the domain) has two different y values (the range values). Then you don't have a function.

To try and make it clearer if 1 pointed at both 3 and 5 you would not have a function.
