The time taken by Jill and Cheryl to double their money is 12 years and 18 years respectively.
<h3>What is Algebra?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
Jill invested $500 in an account with a compound interest rate of 6%.
Cheryl invests $600 in an account with a compound interest rate of 4%.
The number of years each doubles their money. Using the relation of 72.

where r is the interest rate and t be the time
The time for the Jill will be

The time for the Cheryl will be

<h3>
Answer: -2/3</h3>
==================================================
Explanation:
Use the slope formula to find the slope of line E
m = (y2-y1)/(x2-x1)
m = (10-8)/(4-7)
m = 2/(-3)
m = -2/3
The slope of line E is -2/3
The slope of line F is also -2/3 since parallel lines have equal slopes but different y intercepts.
Answer:
J = 15
Step-by-step explanation:
In order to find what the variable equals, you need to put it alone on one side of the equation. So to get rid of the 5, you have to do the opposite of division, which is multiplication. You multiply 5 and 3 to get 15. This will look like:
15 = J
Usually, there is something left to do on the number side, but in this case, there is nothing and you found your answer!
Explecit formula
hmm, seems to be a geometric sequence
so
an=a1+d(n-1)
d=common differnce
a1=first term
given
a1=firstterm=9.2
and the difference between each tierm is 1.8
an=9.1-1.8(n-1) is da equation
so 4th option
When i do it, with the cone formula w volume, i get 678.567 but that’s none of your choices
