Answer:
Step-by-step explanation:
Part A
To keep it simple, I will use v instead of vi, x instead of triangle x and t instead of triangle t.
The equation becomes: x = vt + 1/2at^2
Solve for a:
x = vt + 1/2at^2
x - vt = 1/2at^2
(x - vt)*(2/t^2) = 1/2at^2*(2/t^2) = a
a = 2(x-vt)/t^2
or writing in the right format
a = 2(Δx - viΔt) / Δt^2
Answer:
I'm pretty sure it's a
Step-by-step explanation:
Step 1:
Line up respective variables in column.
.................(1)
.................................(2)
Step 2:
We need to multiply first equation with -2 so that the coefficient of b becomes equal and opposite of -8.
*2
...................(3)
Step 3:
Add equation (2) and (3)
The b terms will cancel out and we are left with only a terms.
-11a = 22
dividing both sides by -11
a=-2
Step 4:
plug this value of a in equation (1) to find value of b,
b=-9
Answer : a=-2 and b =-9

The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.
