The set of points P(0, 3), Q(2, 0), R(4, -3) are collinear and the line has a slope of _____.

Anon25 [30]

If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

PQ → (0, 3), (2, 0).

Substitute:

$m=\dfrac{0-3}{2-0}=\dfrac{-3}{2}=-1.5$

QR → (2, 0), (4, -3).

Substitute:

$m=\dfrac{-3-0}{4-2}=\dfrac{-3}{2}=-1.5$

CORRECT :)

<h3>Answer: m = -1.5.</h3>

Each part of a race is 1/10 mile long. Marsha finished 5 parts of the race.

sesenic [268]

So if you wanna know how long Marsha did you should multiply 1/10 by 5 so you will have: 5/10 which is equal to 1/2 mile :)))
i hope this is helpful

Find the diamter of a circle if its area is 706.9mm²

Masteriza [31]

Answer:

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

<em>r</em><em> - radius</em>

<em />

We have

$A=706.9\ mm^2$

Substitute:

$\pi r^2=706.9$ <em>divide both sides by π</em>

$r^2=\dfrac{706.9}{\pi}$ <em>use π ≈ 3.14</em>

$r^2\approx\dfrac{706.9}{3.14}\\\\r^2\approx225\to r=\sqrt{225}\\\\r= 15\ mm$

The diameter <em>d = 2r</em>.

Therefore

$d=2(15)=30\ mm$

A right triangle has side lengths a, b, and c as shown below.

Musya8 [376]

Answer:

$\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}$

Step-by-step explanation:

Given that

A right triangle has side lengths a, b, and c

Because you did not attached photo of the right triangle so I will assume that:

Side a is the adjacent (A)
Side b is the opposite (O)
Side c is the hypotenuse (H)

(Please have a look at the attached photo)

To solve for the trigonometric functions of x, we need to recall the ratios they represent as shown below.

$\sin x = \frac{O}{H}\\\cos x = \frac{A}{H}\\\tan x = \frac{O}{A}$

EX: the sine of x is equal to the side opposite of angle x over the hypotenuse. Hence, we have the expressions of the trigonometric functions as shown below:

$\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}$

Hope it will find you well
