Answer:
Step-by-step explanation:
The deceleration experimented by the car is the product of kinetic coefficient of friction and gravitational constant:
The initial speed is computed from the following kinematic expression:
Answer:
it has infinitely many solutions
30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
The distance: use absolute value
Between x and 8: x-8
The distance between x and 8: | x-8 |
“is no more than” means it can be that or be less than that, so use ≤
The distance between x and 8 is no more than 4
| x-8 | ≤ 4
8 as that means what two of the same number makes up , in this case 64. 8x8=64
