The question is incomplete. Here is the complete question.
Part A
The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.
Express the toy's value t, in dollars, as a function of time w in weeks after purchase.
Part B
Write an expression to represent the toy's value 10 days after purchase
Answer and Step-by-step explanation: An exponential function is of the form: 
<u>Part</u> <u>A</u>
Translating to the question, the toy's value as a function of time is
To determine constants a and b, we use points given by graph.
First, (0,5) to find a:
a = 5
Now, (3,10) to determine b:
![b=\sqrt[3]{2}](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B3%5D%7B2%7D)
b = 1.26
The toy's value as a function of time in weeks is 
<u>Part</u> <u>B</u>
Since, the function is in weeks:
1 week = 7 days
w weeks = 10 days
Replacing w:
Expression that represents toy's value after 10 days is .
Hi there!
Let r be the number of matches that Rebecca's team won.
We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.
Using this given information, we can create the following equation.
If you wish to solve this, we can subtract both sides by 9 to get the following value for r.
Have an awesome day! :)

Answer:
66528 km
Step-by-step explanation:
1 sec = 3*105
60 sec = 1 min = 3*60*105 km
3.25 min-?
3 .25×60×105
Answer:
3 units
Step-by-step explanation:
Since the y-coordinate is the same. Therefore, there is a straight horizontal line between the two points. So, again, since the y-coordinates are the same, we can subtract C(x) (the x-coordinate for point C) from D(x) (the x-coordinate for point C)
C(x) = 3.5
D(x) = 0.5
3.5 - 0.5 = 3
Therefore, the distance between the two points is 3 units
Answer:
B=29
Step-by-step explanation:
you have on the right hand side 
which is equal to 
so B=49
