Answer:
The best way to know weather the formula y=x⁴-4x³+3x² is growing or not, is by graphing it.
As you can see in the attached picture:
Therefore, the polynomial grows in the intervals stated before.
For this case what we must do is find the unit rate of grams of fat for every tablespoon of the powder.
We have then:
Substituting values we have:
Then, rewriting we have:
Answer:
There are grams of fat are there for every tablespoon of the powder
Answer:
The adult tickets are <u>400</u> and the children tickets are <u>300</u>.
Step-by-step explanation:
Given:
At a carnival, 700 tickets were sold for a total amount of $5500. An adult ticket cost $10 and a children's ticket cost $5.
Now, to find the number of adult tickets and the number of children's tickets sold.
<em>Let the number of adult tickets be </em><em />
<em>And let the number of children tickets be </em><em />
So, the total number of tickets sold:
Now, the total amount of tickets:
Substituting the value of from equation (1):
<em>Subtracting both sides by 3500 we get:</em>
<em /><em />
<em>Dividing boths sides by 5 we get:</em>
<u />
<u>The number of adult tickets = 400.</u>
Now, substituting the value of in equation (1) we get:
<u>The number of children tickets = 300.</u>
Therefore, the adult tickets are 400 and the children tickets are 300.
