A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitutes solutions of the system.
According to the definition, is a parabola is in the standard form of (x-h)^2<span>=4p(y-k), then the directrix is y=k-p. In this case, the parabola function is x^2=8y, so h=0, p=8/4=2, k=0. Plug the values of h, p, k, into y=k-p, the directrix is y=-2.</span>
Answer: 108pi
Step-by-step explanation:
36pi times 3
this is correct btw
Hey there!!
We know:- <em>Vertically opposite angles are equal. </em>
Hence,
Angle 1 = Angle 2
... 6x + 11 = 10x - 9
... 20 + 6x = 10x
... 20 = 4x
... x = 20 / 4
... x = 5
Angle 1 = 6x + 11
... 6 ( 5 ) + 11
... 30 + 11
... 41
<em>Hence, the measure of angle 1 is 41 degrees. </em>
Hope my answer helps!
