Answer:8. 4.2*10^–3 and 7. No

Step-by-step explanation: To find the answer for question #8, move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal. For question #7 the same thing for question #8 must be move to the decimal so there is one non-zero digit to the left of the decimal point.

WE has endpoints at<br>W(10, 2) and E(5, -3).<br>How long is WE?

s2008m [1.1K]

Answer:

$WE=5\sqrt{2}$

Step-by-step explanation:

Distance between two points:

The distance between $(x_1,y_1)$ and $(x_2,y_2)$ is given by $=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2$

Hence distance between $W(10,2)$ and $E(5,-3)$

$WE=\sqrt{(5-10)^2+(-3-2)^2}=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}\\\\WE=\sqrt{50}=5\sqrt{2}$

Cubic stack would mean all the sides are the same length.

The length of the side is given as 3 yards.

Volume = 3^3 = 3 x 3 x 3 = 27

Volume = 27 cubic yards.
