Answer: Liza invested $15000 at 3% and $30,000 at 4%
Step-by-step explanation:
Let x be the amount invested by Liza at 3% interest then the amount she invested in 4% interest will be 2x.
We know that the compound interest with principal P is give By
, where n is the number of period.
Now, interest earned in 3% (in decimal 0.03) account in 1 year is given by:-
Similarly, interest earned in 4% (in decimal 0.03) account in 1 year is given by:-
According to the question,
Also, 2x=2(15000)=30000
Therefore, Liza invested $15000 at 3% and $30,000 at 4% .
The answer is 7

Answer:
x > -1
Step-by-step explanation:
p = (f o g)(x) = log ((x+4)-3)
p = log (x+1)
so that p has a value,
the value of x + 1 mus be greater than 0
x + 1 > 0
x > -1
so the domain is x > -1
Domain = {x | x > -1, x must real number}
