Answer:
y= 18x+50
x=number of weeks
Step-by-step explanation:
x=number of weeks
y=spanish clubs account balance
18 is your slope (every week they get 18 more dollars)
50 is your y intercept or your starting balance
I believe the answer is 18 gallons.
6/9-4/9=2/9
Best Answer: Eighteen.... yes, I read it right. *sigh*
First convert 2/3 into ninths.
2/3 = 6/9
Therefore 2/9 is equal to 4 gallons...
Therefore 1/9 is equal to 2 gallons...
9 multiplied by 2 gallons is 18 gallons.
Answer:
f(x) = 3x^3 +10x^2+4x-8 =( -2, 2/3)
The tree died about 3357 years ago.
Explanation:
The half life of carbon - 14 is given by
where 
Substituting these values in the above equation, we get,
Taking In on both sides of the equation, we get,
Since, only 66% of Carbon - 14 remains after the time T.
Thus, we have,
Taking In on both sides of the equation, we get,
Thus, the tree died about 3357 years ago.
