Answer:
5x^4 - 37x^3 - 6x^2 + 41x - 6
Step-by-step explanation:
Let x be the number of ordinary cars
Let y be the number of SUV's
The difference between the number of ordinary cars and the number of suvs is 17.
So x-y=17 ----> first equation
The number of ordinary cars is larger than the number of sport utility vehicles by 77.3%.
ordinary cars = SUV + 77.3% of SUV
x = y + 0.773y
x = 1.773y
Now we solve for y
We plug in x=1.773y in first equation
1.773y - y=17
0.773y = 17
y = 21.9922
Number of SUV's = 22
For this case we have the following equation:
v = v0 + at
Where, we have the following values:
v0 = 20 meters / second
a = 1.5 meters / second2
t = 4 seconds
Substituting values we have:
v = 20 + (1.5) * 4
v = 26 meters / second
Answer:
The car's final velocity is:
v = 26 meters / second
Is the answer 15? If not are there any options?
