Answer:
The answer is the attached graph.
Step-by-step explanation:
We have to know about exponential function.
The general Exponential Function is:
Where:
a is any value greater than 0
Properties depend on value of "a"
- When a=1, the graph is a horizontal line at y=1
- It is always greater than 0, and never crosses the x-axis
- It always intersects the y-axis at y=1, that it means, it passes through (0,1)
- Its Domain is the Real Numbers: R
- Its Range is the Positive Real Numbers: (0, +∞)

Answer:
$16.
Step-by-step explanation:
Let t represent the cost of each tree.
We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.
We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be
The total cost of purchasing 8 trees will be .
Since the total cost of the trees including the delivery was $168, so we can get an equation as:
Upon dividing both sides of our given equation by 8, we will get:
Therefore, the cost of each tree is $16.
Answer:
Both sizes are better because they cost Same.
Step-by-step explanation:
Consider the provided information.
A coupon offers $1.00 off the 16
Quantity Price
Pint 16 $3.98
Quart 32 $5.98
If he gets $1 off for the 16-ounce size. The price will be:
3.98-1=2.98
He needs to pay $2.98 for 16-ounce pint.
Now find which one is better by calculating the unit rate.
Therefore, the cost of 1lb would be $0.186
For Quart 32 find the unit rate as shown:
Therefore, the cost of 1lb would be $0.186
Hence, both of the size are better as the unit rate is same.
