Answer:
the earth spins 1,600 km per hour so times 4 is 6,400 and convert that to a fraction i'm not sure if this is right
Step-by-step explanation:
Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like <em>f(x)=</em> <em>23y-5 </em>(that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise. <em />
Answer:
-2
Step-by-step explanation:
17.8 + f =
17.8 + (-19.8)
= -2
Answer:
b) AC
Step-by-step explanation:
Exterior angle C is the sum of interior angles A and B. If angle A is 70, then angle B is 120-70 = 50. Angle C is the supplement of its exterior angle, so is 180-120 = 60.
The smallest angle is B, so the opposite side, AC, is the shortest side.
