This is one of the two tired triangles of trig you should memorize. An isosceles right triangle has its sides in ratio $1:1:\sqrt 2$ . That means the hypotenuse is the square root of two times either side.

$u = \sqrt{2} \times \sqrt{2} = 2$

Answer: C

If you didn't know you could write

$v = \sqrt 2$

$v^2 + v^2 = u^2$

$u^2 = 2 + 2 = 4$

$u = 2$

DOMAIN: RANGE FUNCTION: PLZZ HELP HURRYY‼️‼️‼️

GaryK [48]

Answer:

The input (domain) are usually on the left side of the circle.

Domain = [-2, 0, 3, 4, 6]

The output (range) are usually on the right side of the circle.

Range = [-3, -2, 0, 1, 2, 4]

Since the domain of 3 is pointing at two ranges (3, 4) and (3, -3), the x value repeats.

Functions do not have repeating x values.

The picture shown is not a function.

SOLVE Janet piano teacher charged $12.50 for a 30-minute lesson if Janet has a 4 lesson per month how much will she owe her pian

miskamm [114]

You would multiply 12.50 by 4 because thats how much each lesson is and you go 4 times a month. You then multiply this by 12 because there are 12 months in a year. The answer comes out to $600 a year. Hope this helps. XD
