Answer:
The cost of 12 trading cards are less than $12 so we can say that unit price of the card is lesser than $1.
Unit price per card is $0.46.
Step-by-step explanation:
Given:
Cost of 1 package of trading card = $5.52
Number of trading card in a package = 12
We need to explain how can we tell that the unit price per card is less than $1.
Also We need to unit price per card.
Solution:
Now we can see that;
Cost of 1 package of trading cards is $5.52
And we know that;
1 package contains 12 trading cards.
It means that;
Cost of 12 trading cards is $5.52.
From above we can say that;
If the cost of 12 trading cards were $12 or more than $12 than we would say that unit price of the card is $1 or greater than $1 respectively.
But the cost of 12 trading cards are less than $12 so we can say that unit price of the card is lesser than $1.
Now we will find the unite price per car.
12 trading cards =$5.52
1 trading card = Cost of 1 trading card.
Using Unitary method we get;
Cost of 1 trading card =
Hence Unit price per card is $0.46.
Answer:
The function is decreasing in the following intervals
A. (0, 1)
C. (2, pi)
Step-by-step explanation:
To answer this question, imagine that you draw lines of slope m parallel to the function shown at each point.
-If the slope of this line parallel to the function is negative for those points then the function is decreasing.
-If the slope of this line parallel to the function is positive for those points then the function is increasing.
Observe in the lines drawn in the attached image. You can see that they have slope less than zero in the following interval:
(0, 1) U (2, pi)
Therefore the correct option is:
A. (0, 1)
C. (2, pi)
