Answer:
Δx= 184.12 ft
Step-by-step explanation:
The equation you need to use is velocity as a function of displacement.
v = the speed at which the car is travelling,
and
v_o is the original speed (in this case zero).
The change in x (displacement) is how far the car travels. You will be solving for a (acceleration).
solving we get
a= 12.19
now put this acceleration value into the second case when v= 67mi/h
⇒Δx= 184.12 ft
Answer:
300
Step-by-step explanation:
3 would be extremely low
30 would be low
300 would be about right
3,000 lets not talk about this

Answer:
B. 498
Step-by-step explanation:
First, you figure out what 12 x 40 equal: 12 x 40 = 480.
Then, You figure out what 12 x 1.5 equals: 12 x 1.5 = 18.
Finally, you just add the two together: 480 + 18 = 498.
Hope this helps!!!
Answer:
C. 8 ft.
Step-by-step explanation:
start by identifying your a (1), b (6), and c(-112). you plug them into the quadratic formula or by using this calculator https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php. the two solutions will be x = 8 and x = -14, but of course the reasonable answer is 8 and none of the choices are -14.
