Answer:
t = In2/ r
Step-by-step explanation:
Given the formula : A = Pe^rt
For investment to double ;
Final amount (A) = 2 * initial investment (p)
A = 2p
Hence,
2p = pe^rt
2 = e^rt
Take the In of both sides
In2 = rt
Divide both sides by r
In2 /r = rt /r
In2/ r = t
t = In2/ r ; Hence, the proof
Answer:
12 chocolates
Step-by-step explanation:
Represent the original number of chocolates by c.
Then (1/4)(2/3)c = 2
Solving this for c, we multiply both sides by 4: (2/3)c = 8
and then multiply both sides by (3/2): c = (3/2)(8) = 12
Originally the box contained 12 chocolates.
Answer:
0.5625 ft^2
Step-by-step explanation:
area of square = side * side
A = s^2
A = (0.75 ft)^2 = (0.75 ft)(0.75 ft) = 0.5625 ft^2
