Answer:
Penelope's account balance at the end is $850.70.
Step-by-step explanation:
Penelope has $1,459.75 in her bank account.
To pay her bills, she writes 4 checks for $200.25, $359.45, $125, and $299.35.
Adding all these we get -
After all the bills her balance left = dollars
Now, she deposits $375 into her account.
So, her new balance will be = dollars.
Therefore, Penelope's account balance at the end is $850.70.
Given:
On a graph, points are at (0, 15), (1, 17), (3, 18), (4, 20) and (6, 22).
To find:
The range of x-values extrapolation occurs.
Solution:
Consider the below figure attached with this question.
From the graph or given points it is clear that the x-values are 0, 1, 3, 4, 6.
It means the x-values are from 0 to 6.
So, the range of the x-values is or
.
The required compound inequality for the range of x-values is .
Therefore, the correct option is D.
Answer:
The inverse function is
Step-by-step explanation:
The given function is .
This function is only invertible on the interval, .
To find the inverse on this interval, we interchange and
.
We now make the subject to get,
But the given interval is , This implies that,
.
