The answer is D. x=0 and x=4 because a way to determine the answer is by inputting all the choices for x they have and if any of them has the answer then choose that one
Answer:
x ≈ 14.4
Step-by-step explanation:
using the cosine ratio in the right triangle
cos59° = 
= 
( multiply both sides by 28 )
28 × cos59° , then
x ≈ 14.4 ( to the nearest tenth )
4.2x - 1.4y = 2.1
-1.4y = -4.2x + 2.1
y = (-4.2/-1.4)x + 2.1/-1.4
y = 3x - 1.5 <==
In general, you're calculating the magnitude of average velocity. In fact, speed is a vector, and as such it also has a direction and orientation.
So, if you compute the average speed, you're assuming that you went directly from point A to point B, which is basically never the case.
If, instead, you actually moved on a straight line from point A to point B, then the two quantities are the same.
Answer:
4/5 in one hour
Step-by-step explanation:
15 minutes is 1/4 of an hour so all you need to do is multiply one 1/5 by four
tell me if im wrong plz
