Answer:
log_e(x)=ln(x)
Step-by-step explanation:

it's something predefined
because e is an important constant, it's the natural log
Answer:
Mass of planet B is larger than A by 500 times
Step-by-step explanation:
Mass of planet A= 8*10^24
Mass of planet B= 4* 10^27
Larger Mass= Mass of planet B
Mass of planet B/Mass of Planet A= 4* 10^27/8*10^24
=1*10^(27-24)/8
=(1*10^3)/2
=1/2*10^3
=1000/2
Therefore by, 500 times.
Answer:
Option- one is correct.
The given system of equations have one solution that is (7,-21)
Step-by-step explanation:
Given system of equations are


Now to the solution:
To solve the given system of equations using substitution method.
That is substitute equation(1) in equation (2) we get
(here y=-3x)

(adding the like terms)

Therefore x=7
Now substitute x=7 in equation (1) we get



Therefore the solution is (7,-21)
Therefore Option- one is correct.
The given system of equations have one solution that is (7,-21)
Saying m is multiple choice questions, that equation would be:
14m+24=16m+14
subtract the 14 from each side to get:
14m+10=16m
subtract the 14m from each side to get:
10=2m
divide each side by 2 to get the answer:
5=m
multiple choice questions are worth 5 points.
The answer would be $280.00.
