Answer:
f(4)=2(x)^2-5(4)+4
Step-by-step explanation:
f(x) is basically just y, but it is also telling you what the value of x is. So if f(4) then that means that x is 4, so you can just replace x with 4 and simplify. Hope this helps :)
Answer:
Subtract 60 from the sum of 8e and 20 when e=7
8e +20
8(7) + 20
56+20=76
76-60=16
A computer drawing program generally has more steps compared to using a compass and straightedge, although not by much. In a computer drawing program, you can erase an error within a click of a button, compared to having to manually perfect and erase your work when using a compass and straightedge. Also, you immediately have access to an online drawing program as long as you have Internet connection and a computer compared to having to go out and buy a new compass and straightedge. Other than that, they're generally the same despite being different mediums.
Hope this helps!

Answer:
r
Step-by-step explanation:
Since r is not given, the length we can be find using the Law of Sines using is length r.
The Sine formula or the Law of Sines
q/Sine Q = r/Sine R
q=9.5
r is the unknown
9.5/Sine 18° = r/ Sine 135°
