Answer:
$14.5
Step-by-step explanation:
Given data
Cost for the visit=442.25 Rubles
exchange rate
3 USD= 91.5 Rubles
but 1 USD= 91.5/3
= 30.5
Therefore if 1 USD is 30.5 Rubles
Then xUSD is 442.25 Rubles
cross multiply
30.5x= 442.25
divide both sides by 30.5
x= 442.25/30.5
x=14.5USD
The cost of the attraction is $14.5
The real estate agent has a commission rate of 33.3%
if youy divide 240000 by 7200 then you would get 33.33333333
which would mean she has a (1/3) commission rate. hope this helps you out!

Given that a polynomial function P(x) has rational coefficients.
Two roots are already given which are i and 7+8i,
Now we have to find two additional roots of P(x)=0
Given roots i and 7+8i are complex roots and we know that complex roots always occur in conjugate pairs so that means conjugate of given roots will also be the roots.
conjugate of a+bi is given by a-bi
So using that logic, conjugate of i is i
also conjugate of 7+8i is 7-8i
Hence final answer for the remaining roots are (-i) and (7-8i).
