Answer:

I think the answer is 50 .

Step-by-step explanation:

this is what I did

Pythagoras therome: a^2 +b^2 = c^2

So I did 30^2 +40^2 = 2500

square root of 2500 is 50

So I think the option is 50

Answer:

$x^\frac{5}{3} y^\frac{1}{3}$

Step-by-step explanation:

This question is on rules of rational exponential

where the exponential is a fraction, you can re-write it using radicals where the denominator of the fraction becomes the index of the radical;

<u>General expression </u>

$a^\frac{1}{n} =\sqrt[n]{a}$

Thus $\sqrt[3]{x} =x^\frac{1}{3}$

<u>Applying the same in the question </u>

$\sqrt[3]{x^5y} =x^\frac{5}{3} y^\frac{1}{3}$

= $x^\frac{5}{3} y^\frac{1}{3}$

laiz [17]

Answer:

Step-by-step explanation:

|((experimental - theoretical) / theoretical)| x 100

5.5 - 5.62 / 5.62 = -.0213

|-.0213| = .0213

.0213 x 100 = 2.13

Option C: -3 is the average rate of change between $x=-1$ and $x=1$

Explanation:

The formula to determine the average rate of change is given by

Average rate of change = $\frac{y_2-y_1}{x_2-x_1}$

We need to find the average rate of change between $x=-1$ and $x=1$

Thus, from the table, we have,

$x_1=-1$ , $y_1=5$

$x_2=1$ , $y_2=-1$

Thus, substituting these values in the formula, we get,

Average rate of change = $\frac{-1-5}{1+1}$

$=\frac{-6}{2}$

$=-3$

Thus, the average rate of change between $x=-1$ and $x=1$ is -3.

Hence, Option C is the correct answer.
