I don't think this is a mathematical question, but I will be glad to answer :)

The people in the Pacific Northwest able to survive by hunting and gathering because they need food, so they would hunt the animals, and they gathered material to make shelter.

Answer:

the first cell next to 3 (time hours x) is 300

the point is (3, 300)

the second cell is 1000

the point is (10,1000)

the values for the second table should be the same if they have the same unit rate which is 100 watts per hour

Step-by-step explanation:

If there is 100 watts perhour just multiply the number of hours by this unit

The curve with the equation y=8x^2 + 2/x has one turning point.

anyanavicka [17]

Answer:

(1/2, 6).

Step-by-step explanation:

Turning points in a graph may exist whenever the derivative equals 0. Hence, let’s differentiate and then solve our function.

We have:

$\displaystyle y=8x^2+\frac{2}{x}$

Take the derivative of both sides with respect to x:

$\displaystyle y^\prime=16x-\frac{2}{x^2}$

Simplify:

$\displaystyle y^\prime=\frac{16x^3-2}{x^2}$

We will now set this equal to 0 and solve for x. Hence:

$\displaystyle \begin{aligned} 0&=\frac{16x^3-2}{x^2} \\ 0&=16x^3-2 \\ 2&=16x^3 \\ \frac{1}{8}&=x^3 \\ \frac{1}{2}&=x \end{aligned}$

Hence, the graph turns at x=1/2. This is the x-coordinate.

Then it follows that the y-coordinate will be:

$\displaystyle{\begin{aligned} y&=8(\frac{1}{2})^2+\frac{2}{\frac{1}{2}} \\ y&=8(1/4)+2(2) \\ y&=2+4 \\ y&=6\end{aligned}$

Hence, our coordinate Is (1/2, 6).
