Answer:

20.78

Step-by-step explanation:

sin a = perpendicular/ hypotenuse

where a is the base angle

here a = 60

sin 60 = 18/ x

since,

$\sin(60) = \ \frac{ \sqrt{3} }{2}$

$\frac{ \sqrt{3} }{2} = \frac{18}{x}$

√3 x = 36

x = 36/ √3

x = 36/ 1.732

x = 20.78

Which point is a reflection of T(-6.5, 1) across the x-axis and the y-axis?

drek231 [11]

First, start off with the x-axis. -6.5, 1 becomes 6.5, 1. This is because point T is 6.5 to the left of the x-axis line, so our new point would be 6.5 to the right of the x-axis line. Same thing for the y-axis, (6.5, 1) would become (6.5, -1).

Determine the value(s) for which the rational expression 2x^2/6x is undefined. If there's more than one value, list them separat

Dmitry [639]

Answer:

Step-by-step explanation:

Hello, dividing by 0 is not defined. so

$\dfrac{2x^2}{6x}$

is defined for x different from 0

This being said, we can simplify by 2x

$\dfrac{2x^2}{6x}=\dfrac{2x*x}{3*2x}=\dfrac{1}{3}x$

and this last expression is defined for any real number x.

Thank you
