Find the distance between each pair of points. Leave your answers in simplest radical form.

Oksanka [162]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

1. (6, 8), (5, 5). Substitute:

$d=\sqrt{(5-6)^2+(0-8)^2}=\sqrt{(-1)^2+(-8)^2}=\sqrt{1+64}=\sqrt{65}$

2. (-3, -2), (-5, 3). Substitute:

$d=\sqrt{(-5-(-3))^2+(3-(-2))^2}=\sqrt{(-2)^2+5^2}=\sqrt{4+25}=\sqrt{29}$

The graph shows the influence of the temperature T on the maximum sustainable swimming speed S of Coho salmon. (b) Estimate the

Alex17521 [72]

From the graph it appears that S′(5) 2 ≈ and S′(25) 2 ≈ − . The important thing is that they do have opposite signs. The first means that at about 5ºC the Coho gains about 2 cm/sec while at 25ºC it loses about 2 cm/sec in maximum sustainable speed.

Which of the following proportions could be used to find x?

OLga [1]

$\frac{x}{2}$ = $\frac{6}{1.5}$

The 2 right triangles are similar and so the ratios of corresponding sides are equal

The corresponding sides are x and 2, 6 and 1.5, hence

$\frac{x}{2}$ = $\frac{6}{1.5}$
