Answer:
f(x)=104x-x^2
Step-by-step explanation:
Let
x = number of tickets sold.
example, 2 tickets cost 2 · 408 = $816
3 tickets cost 3 · 404 = $738.
The cost of buying x tickets= the number of tickets sold × the price of each ticket.
If x tickets are sold, then the price of each ticket is 412-4(x-1)
Then the quadratic function that gives the total cost of buying x tickets is given by
Cost =quantity sold*price
=412-4(x-1)*x
=(412-4x+4)*x
=412x-4x^2+4x
=416x-4x^2
Divide through by 4
=104x-x^2
Therefore, the required quadratic function is
f(x)=104x-x^2
Answer:
<em>A. minus 10,</em>
Step-by-step explanation:
The distance travelled must be positive.
Therefore minus 10 would not be a reasonable answer.
<h3>The temperature drop from the morning to the night is -16.8 F</h3>
<em><u>Solution:</u></em>
Given that,
The temperature in the morning was -4 F
At night the temperature dropped to -12.8 F
To find: temperature drop from the morning to the night be represented
From given,
Morning = -4 F
Night = -12.8 F
Therefore,
Temperature drop from the morning to the night = -4 - 12.8 = -16.8 F
Thus the temperature drop from the morning to the night is -16.8 F
