Work out 6% of $42 which equals to $2.52. The work out what 20% of $42 which is $8.40. Finally add the $8.40 and $2.52 onto $42 to give you your answer of $52.92
Answer:
2a + 2b + 6c.
Step-by-step explanation:
To find this we subtract :-
3a + 5b + 7c - (a + 3b + c)
= 3a + 5b + 7c - a - 3b - c Now combine like terms:
2a + 2b + 6c (answer).
The formula for exponential growth is written as y = a(1 + RATE)^time
where a is the starting value, rate is the percentage of growth written as a decimal and time in this case would be the number of days.
You are given the growth rate as 11% and the starting day was day 1.
Since the table only goes to 10 days, you can use 10 as the time, or use X as an exponent if you need to calculate more than 10 days.
Using all this information, the formula becomes y = 1(1.11)^10 for 10 days or y = 1(1.11)^x for any number of days needed.
Answer:
The choices were typed wrong, but we can find the inverse of each option.
For function 
the inverse is the same function 
, because an inverse of a function is where their composition gives the independent variable as unique result.
If we do that with each function, we have:
; where and , we have
So they are inverse.
For 
its inverse would be 
, because
For 
, its inverse is 
, because
For 
, its inverse is 
, because
There you have all inverses. Basically, if their composition results in 
, that means they are inverse.
