How to solve this??? e^(2x) - e^x = 6

Mathematics
1 answer:
Ray Of Light [21]3 years ago
5 0
e^{2x}-e^x=6
(e^x)^2-e^x-6=0
(e^x-3)(e^x+2)=0

e^x=3
e^x=-2

therefore x=\ln3 and x=\ln-2
because \ln-2 doesn't exist, the only solution to your equation is x=\ln3

Alinara [238K]

It was 1.5 times the length of Noah's bike ride as Mai’s bike ride.

The problem we dealing with is related to mixed numbers which are referred to as mixed numbers and could be the whole number, and a proper division spoke together. It for the most part speaks to a number between any two whole numbers.

Since we are providing mai's rate which is  6 3/4  miles and Noah's  rate of 4 1/2 miles, So in  order to find the time the length of Noah's ride is compared to Mal's, we just need to divide the given rates by each other

=> 6 3/4 divided by 4 1/2,  

=> 27/4 divided by 9/2, (The result is an improper fractions)

=> 27/4 X 2/9

=>3/2

=> 1.5

jason wants to choose 9 players for his track team ,there are 12 players to choose from.how many different teams can jason make?
Schach [20]
He could only make one team, considering that if you do 12-9, you are left with 3, and Jason wants to have his team consisted of 9 players. However, if you make 3 teams with 4 players on each team, or 4 teams with 3 players on each team, you could do that as well.
