Answer:
A) 0.106
Step-by-step explanation:
8e^3x + 4 = 15
Subtract 4 from each side
8e^3x + 4-4 = 15-4
8e^3x = 11
Divide each side by 8
8/8e^3x = 11/8
e^(3x) = 11/8
Take the natural log of each side
ln(e^(3x)) = ln(11/8)
3x = ln(11/8)
Divide by 3
3x/3 = 1/3 ln(11/8)
x = 1/3 ln(11/8)
x =.106151244
To the nearest thousandth
x = .106
Answer:

Step-by-step explanation:
We have been given an expression
. We are supposed to combine like terms for our given expression.
We can see that
are like terms as both of these terms have x variable.
Similarly,
are like terms as both are constant.
Upon combining like terms, we will get:


Therefore, our required expression would be
.
Answer:
6:15
Step-by-step explanation:
Multiply the car by 2: 300 meters x 2 = 600 meters
30 seconds x 2 = 60 seconds.
The car also traveled 600 meters in 60 seconds, so the speed of the vehicles are the same.
No vehicle was faster.
