Arc with endpoints that are the endpoints of a diameter is called a semicircle and has a measure of 180 degrees. Adjacent arcs are two arcs on the same circle which d<span>o not overlap and s<span>hare a common end point. Hope this answers the question.</span></span>
Answer:
I hope this helps
Step-by-step explanation:
About 5 minutes: 60/4=15 then 15*3=45 and so 45/9 is 5 about 5 minutes an application

It is important to notice firs of all that the train with no stop acceleration and them no stop acceleration would have a faster travel between stops. given this is safe to assume that there is a period during while the train is not accelerating nor decelerating. To find the time that is speed is constant
let's assume non-stop accelerating and decelerating and the time lost (subtraction of both) is the time the train had constant speed:
assuming same time accelerating a decelerating we have that the distance is
x = voT + 1/2aT^2 (initiial speed = 0) (0.25 miles = 1320 feets)
1320 = 1/2 (8)(T/2)^2
T/2 = 18.17 seg
T = 36.34 seg
time of constant speed
T = 41 -36.34 = 4.66 seg
maximum speed
v = v0 + aT (initial speed = 0)
v = 8(18.17) (time accelerating)
v = 145.36 feets/sec
distance at full speed
x = v*t
x = 145.36*4.66 = 677.38 feets
Answer:
4/7
Step-by-step explanation:
9 - 1 = 8
8/14 = 4/7
