Answer:
43.82 mph
266.67 feet
Step-by-step explanation:
Given :
S = √30fl
S = speed of car
f = drag Coefficient
l = Length of skid mark
If f = 0.8 ; l = 80 feets
s = √30fl
s = √(30*0.8*80)
s = √1920
s = 43.817
s = 43.82 mph
B.)
s = 80 mph
f = 0.8
s = √30fl
80 = √30*0.8*l
80 = √24l
Square both sides
80² = 24l
6400 = 24l
l = 6400/24
l = 266.67 feets
The answer would be 8.36x10^8
The answer you are looking for is 45
Answer:
4
Step-by-step explanation:
6,12,18,14,30,35 only four numbers that are between 15-35
(-4,0)
(2,0)
(2,0)
You set the equation equal to zero and you get -4,2,2 and if u plug this numbers in to get y then you get 0
