What you can use for this case is a function of the potential type.
We have then
y = a (b) ^ x
Where we have:
Walker starts the fund by depositing $ 5
a = 5
Each week the balance of the fund is twice the balance of the previous week:
b = 2
The function is:
y = 5 (2) ^ x
The number of weeks to reach $ 1280 is 8 weeks.
Check:
y = 5 (2) ^ 8
y = 1280
Answer:
An equation can be used to find the number of weeks, x, after which the balance of the fund will reach $ 1,280 is:
y = 5 (2) ^ x
The number of weeks that it takes to reach the class goal is
8 weeks
The decimal form would be 3.6
Answer: C. Rectangles 1 and 3
Step-by-step explanation:
1. By definition, two rectangles are similar if they have equal shape bot do not have equal sizes.
2. You can know it the rectangle 1 and 3 are similar by the following proportions:
Where is the lenght of the rectangle 1, is the lenght of the rectangle 2, is the width of the rectangle 1 and is the width of the rectangle 2.
3. Subtitute values:
4. Then, the rectangle 1 and 3 are similar.
