2x^3-2x^2+3x^2-3x-6x+6
2x^3+x^2-9x+6
Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°
Answer:
Wait wait wait this makes no sense?
Step-by-step explanation:
Answer:
B: 57 mph=57 mph
Step-by-step explanation:
A steady pace means constant speed that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)
![v= \frac{x - xo}{t -to}](https://tex.z-dn.net/?f=v%3D%20%5Cfrac%7Bx%20-%20xo%7D%7Bt%20-to%7D)
where x is distance and t time. The subtract is final value minus initial value
We have the distance and time, then
