Now before taking the inverse tangent of both sides, recall that

where

is any integer. This means that when taking the inverse tangent of

, instead of just

, we would end up with

So after doing so in the equation above, we're left with

As

can be any integer, including negative integers, we can simply write

Hello again!
when he invested $4000 at 5% he increased his income from 0 to 200
adding 4% of 3500 increased it by 140
totaling to $340
he has $2500 left. and he needs $160 more income
160 is 6.4% of 2500
so he needs to invest the remaining $2500 at 6.4% to get the last $160
of his income
I hope this helps, and have a nice day!

Answer:
2.75 miles jogged on the fourth day
Step-by-step explanation:
Justin jogged 2 miles on the first day.
On the second day he jogged 75% of 2 miles. To find 75% of 2 miles we need to divide by 100 and multiply by 75.
2 / 100 = 0.02 x 75 = 1.5 miles jogged on the second day. (3.5 miles jogged in total so far)
On the third day he jogged 1.5 miles more than the last day:
1.5 + 1.5 = 3 (6.5 miles jogged so far)
9.25 total miles were jogged, meaning that we will need to subtract 6.5 from 9.25 to get the answer:
9.25 - 6.5 = 2.75 miles jogged on the fourth day
