velikii [3]

Step-by-step explanation:

Given binomial is: $8x^4 - 2x$

$in \: the \: term \: 8 {x}^{4} \\ coefficient = 8 \\ exponent = 4 \\ \\ in \: the \: term \: - 2x \\ coefficient = - 2 \\ exponent = 1$

A motorboat travels 204 kilometers in 6 hours going upstream. It travels 372 kilometers going downstream in the same amount of t

Arturiano [62]

9514 1404 393

Answer:

boat: 48 km/h
current: 14 km/h

Step-by-step explanation:

The upstream speed is ...

u = (204 km)/(6 h) = 34 km/h

The downstream speed is ...

d = (372 km)/(6 h) = 62 km/h

The speed of the boat in still water is the average of these values:

b = (34 kph +62 kph)/2 = 48 kph

The speed of the water is the difference between the boat's speed and the speed made good:

w = 48 -34 = 14 . . . km/h

The rate of the boat in still water is 48 km/h. The rate of the current is 14 km/h.

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 $E(5,-3)$

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