The rule states that

(a^b)^c = a^{bc}

So, in your case, you have

(9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, the points are given as follows:

(-4,-32), (-2,-8), (0,10), (2,8), (4,32).

Using the calculator, the equation is:

y = 7.2x + 2.

Hence the slope is of 7.2.

How many apples?<br> Help me please, thanks so much
Anna71 [15]

The number of Apples that were in the given fruit salad is approximately; 2170 Apples.

<h3>How to work with ratio questions?</h3>

We are given the ratio of apples to oranges as;

A:O = 31:11

Now, we are told that there are 2940 apples and oranges in total.

Thus, the fractions of apples and oranges of the total will be;

Apple fraction = 31/(31 + 11) = 31/42

Orange Fraction = 11/42

Thus;

Number of Apples = (31/42) * 2940

Number of Apples = 2170 Apples

HELP QUICKLY PLEASE!!! for y = 3x - 2x^2 + 5x^3, show how to find the value for y, when x = 3. please show your work.
Brrunno [24]
All you need to do is plug in 3 wherever you see an x!
y = 3(3) - 2(3)^2 + 5(3)^3
y = 9 - 2(9) + 5(27)
y = 9 - 18 + 135
y = -9 + 135
y = 126
Hope this helps!
