If the moon is directly over the beanstalk, how many days after the beanstalk was planted would the beanstalk reach the moon? (T

olchik [2.2K]

Answer:

28.23 days

Explanation:

Length of magic beanstalk=4 feet

Height increasing exponentially and double each day.

We have formula

$y=a(b)^t$

Where t=Time (in day)

We have a=4

When t=1 then y=8

$8=4b^1$

$b=\frac{8}{4}=2$

$b=2$

Distance between moon and earth=y=238,900 miles= $238900\times 5280 feet$

Substitute the values

$238900\times 5280=4(2)^t$

$\frac{238900\times 5280}{4}=2^t$

$315348000=2^t$

$ln(315348000)=tln 2$

$t=\frac{ln315348000}{ln 2}$

$t=28.23 days$
