You should get photo math it’ll answer it for you and show you how
Answer:
I think that if u times it i will be 80 s and 320 f
Step-by-step explanation:
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, 3)
Step-by-step explanation:
This is an increase of 8 in the y coordinate, so the answer is (-4, -5 + 8) or (-4, 3).
Answer:
Step-by-step explanation:
50 gallons(8 pints/gallon) = 400 pints
400 pints(4 drops/pint) = 1600 drops red dye
400 pints(3 drops/pint) = 1200 drops blue dye
