WILL GIVE BRAINLIEST!! 2) Match the graph with its function. Which is an example of growth/decay?
1 answer:
The exponential growth is:
And its graph is the first one.
The exponential decay is:
And its graph is the second one.
<h3>How to identify the exponential equations?</h3>
The general exponential equation is of the form:
Where A is the initial value and b is the base.
- If b > 1, then we have an exponential growth.
- if 1 > b > 0, then we have an exponential decay.
Here the two functions are:
As you can see, the base for the first one is smaller than 1, then it is an exponential decay (and it has a decreasing graph, so the graph of this one is the second graph).
For the second function, we have the base b = 1.25, which is larger than 1, so it is an exponential growth, and its graph is an increasing graph, which is the first one.

Answer:
Nina would have total expenses and sales $156 after selling 4 necklaces.
Step-by-step explanation:
Let <em>x</em> represent the amount of necklaces made and sold.
The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing <em>x</em> necklaces can be represented as:
Each necklace sells for $39. Hence, the total profit after selling <em>x</em> necklaces can be represented as:
To break even, the total cost and profit must be equivalent. Hence:
Solve for <em>x: </em>

<em />
Hence, the break even, Nina would need to sell four necklaces.
And the total expenses/profit would be:
In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.
