Answer:
x = 0 , 2/3
Step-by-step explanation:
3x^3-x^2=x^2
3x^3-2x^2=0
x^2(3x-2)=0
Now split into two equations:
1)
x^2=0
x=0
2)
3x-2=0
3x=2
x=2/3
Answer:
She would have scored 75 points.
Step-by-step explanation:
Points scored in a basketball game vary directly with shots taken.
This means that this question can be solved by proportions, using a rule of three.
How many would she have scored if she takes 60 shots?
Using a rule of three:
50 points - 40 shots
x points - 60 shots
Applying cross multiplication:
Dividing both sides by 40
She would have scored 75 points.
Add 11 to both sides:
-4=-2t
divide 2 by both sides
2=t

Once you remember the definition of a log, the answer to this question will literally fall out of your pencil.
First, ' Ln ' means 'natural log' ... logs to the base of ' e '.
Definition of the natural log of a number:
In order to get the number, what power do I have to raise ' e ' to ?
OK. What power do you have to raise ' e ' to in order to get 1/e² ?
Isn't 1/e² the same thing as e⁻² ?
So, in order to get 1/e² , you have to raise ' e ' to the -2 power .
In math-speak: Ln(1/e²) = <em><u>-2</u></em> .
