Answer:
C) About $85
Step-by-step explanation:
Please consider the complete question.
Carl puts $1.10 in his penny bank every day in the month of July (31 days). His total saving at the end of June is $55.00. What is the best estimate at the end of July?
A) about $25
B) about $115
C) about $85
D) about $66
First of all, we will round $1.10 to nearest whole number and round 31 to nearest tens as:


So amount saved in 30 days would be 30 times $1.


Carl's savings at the end of July would be amount saved in June plus amount saved in July that is 
Therefore, the estimate for Carl's saving at the end of July is $85 and option C is the correct choice.

Step-by-step explanation:
the simpliest form is 
Answer:
g (f(2)) = 3
Step-by-step explanation:
f (x) = x2 – 4
g(x) = x + 3
g (f (2)) =?
Find f(2) first
f (x) = x2 – 4
f (2) = 2^2- 4
= 0
Now put this in your g(x)
g(x) = x + 3
g (f(2)) = (f(2)) + 3
And u alredy know f(2) =0, so just put it in
g (f(2)) = 0 + 3
=3
Answer:

Step-by-step explanation:
We have to arrange the functions given in ascending order which have eventually the least value and eventually the greatest value.
So, we get the following table representing the values of the functions for different values of x.
x : 5 10 15
: 23 38 53
: 1027 1048579 1073741827
: 31 106 231
: 15 30 45
: 1024 1048576 1073741824
: 25 100 225
As, can be seen from the table that the ascending order of the functions is given by
.
Hence, the order is
.
