Answer:
3^2 + x^2 = 9^2
9 + x^2 = 81
x^2 = 72
x = 
, which is about 8.5
Cosine X = 3/9
Cosine X = 1/3
angle x= 70.5
If angle x= 70.5, angle z = 19.5 degrees.
Let me know if this helps!
Step-by-step explanation:
the steeper line is y = 6x + 11 because its gradient 6, is bigger than 3
Answer:
perpendicular
Step-by-step explanation:
Interpreted by text, we have got 2 function; 1 that describes the costs for ther performance and the other demonstrates the revenue.
f(x)= 1000x + 30 000
g(x)= 2500x
Two ways to work out when the school breaks on the
production of the play.
1- set these functions in geogebra and observe where cross each other. This value will be the answer as g goes higher than f
2- solve as an equation=> set f(x)=g(x) and work out the and afterward set the x value in f or g to find out the y coordinate
