Mumz [18]

Answer:

AB is A

BC is B

AC is D

Step-by-step explanation:

To find the length of each side, use the formula for the distance between coordinate pairs.

We can find the distance using the distance formula:

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

AB

We then substitute (-3,6) as $(x_1,y_1)$ and (2,1) as $(x_2,y_2)$ .

$d=\sqrt{(2--3)^2+(1-6)^2} \\d=\sqrt{(2+3)^2+(-5)^2} \\d=\sqrt{25+25}\\d=\sqrt{50}$

BC

We then substitute (2,1) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9-2)^2+(5-1)^2} \\d=\sqrt{(-7)^2+(4)^2} \\d=\sqrt{49+16}\\d=\sqrt{65}$

AC

We then substitute (-3,6) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9--3)^2+(5-6)^2} \\d=\sqrt{(12)^2+(-1)^2} \\d=\sqrt{144+1}\\d=\sqrt{145}$

PLS HELP!

polet [3.4K]

Answer:

B.) y=csc x

Step-by-step explanation:

The cosecant function has a minimum magnitude of 1, so its range excludes any values in the range -1 < y < 1.

y = csc(x) . . . has a range that does not include -0.8
