For solving this we need the change in distance and the change in time. You said that the change in time is 1.8 seconds and the change in distance is 3.6 meters. ( This is assuming it started at 0 meters and started at 0 seconds )
Since the starting was 0,0 we can toss them out as they add no value. Now since speed is labeled (in this case) m/s, we divide how many meters it traveled over how many seconds it took to travel it.
3.6 / 1.8 = 2
The average speed of the cart is 2 m/s
Answer:
1991
Step-by-step explanation:
I divided 44 by 8 to how many times 362 cars would be made. I got 5.5 and then multiplied that by 362 to see that 1991 cars will be produced.

Answer:
x = 5, x = 11
Step-by-step explanation:
Set f(x) = 0 and solve for x.
0 = (x -8)² -9
9 = (x -8)² . . . . . add 9
±√9 = x -8 . . . . . take the square root
±3 +8 = x . . . . . . . add 8
That is, ...
x = 8 -3 = 5 . . . . lesser x
x = 8 +3 = 11 . . . greater x

u get 3.77
Answer:
-3 + x^2
Step-by-step explanation:
8+x^2-11
First combine the like terms.
so..
8-11 = -3
= -3 + x^2
but we don't know the value of x so we just leave it as it is.
And they both are not like terms so we cant solve them together so you stop there
Hope that helped!
