Answer:
the X variable
Step-by-step explanation:
it's the same as any other function
Answer: -20, 48
Step-by-step explanation: 5 x -4 = -20 6 x 8 = 48
Let X(t)=the position function with respect to time, t.
We're given:
X(0)=12 (from graph)
v(0)=0
X(2.5)=7
There is enough information to construct X(t).
In general,
X(t)=kt^2+v(0)(t)+x0
where initial velocity=v(0)=velocity at time 0 = 0 (given)
x0=initial position at time 0 = 12 (from graph)
Substituting values, the position equation is
X(t)=kt^2+12
Substituting given value X(2.5)=7 => 7=k(2.5^2) + 12
Solve for k to get k=(12-7)/6.25 = -4/5
The position equation now becomes
X(t)=-4t^2/5+12
For t=25,
X(25)=-4(25^2)/5+12=-500+12 = 488 m
Wow this is gonna take me a while
The value of the first 5 =5,000 which is equal to 5 thousand because it is in the thousands place
the value of the second 5=500 which is equal to 5 hundred because it is in the hundreds place
Hope this helps!! :D
