If the interest is compounded continuously, what interest rate do you need for a 5000 investment to double in 10 years

Mathematics

velikii [3]3 years ago

Answer:

rate = natural log (Total / Principal) / Years

We need 5,000 to become 10,000 in 10 years so,

rate = natural log (Total / Principal) / Years

rate = natural log(10,000 / 5,000) / 10

rate = natural log(2) / 10

rate = 0.69314718056 / 10

rate = .069314718056 which equals

rate = 6.9314718056 per cent

214 people used a public swimming pool. $1.50 for kids and $2.25 for adults. The receipt totaled to $390 How many children and h
zysi [14]

Answer:the number of kids that used the public pool that day is 122

the number of adults that used the public pool that day is 92

Step-by-step explanation:

Let x represent the number of kids that used the public pool that day.

Let y represent the number of adults that used the public pool that day.

214 people used a public swimming pool. This means that

x + y = 214

1.50 for kids and $2.25 for adults. The receipt totaled to $390. This means that

1.5x + 2.25y = 390 - - - - - - - - - -1

Substituting x = 214 - y into equation 1, it becomes

1.5x

1.5(214 - y) + 2.25y = 390

321 - 1.5y + 2.25y = 390

- 1.5y + 2.25y = 390 - 321

0.75y = 69

y = 69/0.75 = 92

Substituting y = 92 into x = 214 - y, it becomes

x = 214 - 92 = 122
