Answer:

b

Step-by-step explanation:

It can only be b because the graph is steadily decreasing (negative slope). if it's raining, the temperature is above freezing, and then the rain would turn to snow if the temperature dropped below freezing. So that matches the graph.

For a, total rainfall in a day, the total would keep going up, so it would have a positive slope.

For c, the speed of the car would be at 0 at the beginning when in's at the stop sign, and the graph is starting out well above 0.

For d, the graph would have to go up then down to represent the hill.

<h3><u>Answer:</u></h3>
  • Option B
<h3><u>Step-by-step explanation:</u></h3>

This is because it is the most suitable option than other graphs. Let's verify all options.

  • Option A => This does not do anything with the graph.
  • Option B => This is the most reasonable option because it states that the weather changes from rainy to snowy. As the graph decreases, the temperature changes.
  • Option C => This graph is halfway correct, but halfway incorrect. This is because if the speed of the car increases, the graph should increase. However, this graph shows the line decreasing. Hence, this does not do anything of the graph.
  • Option D => This graph is halfway correct, but halfway incorrect. This is because if the speed of the bike increases, the graph should increase. However, this graph shows the line decreasing. Hence, this does not do anything of the graph.

Step 1

Revenue (sometimes referred to as sales revenue) is the amount of gross income produced through sales of products or services. This, in the context of the question, means that the revenue generated from the sales of tickets is given by the function below. We are now required to find the price that tickets will be sold at in a day based on the function that will make the revenue to be equal to $0.

The revenue is given by the function;

\begin{gathered} f(p)=150p-5p^2 \\ f(p)\text{ is the revenue and should be equal to 0 according to the question.} \\ p=\text{ The price of tickets for the day for the revenue to be 0} \end{gathered}

To solve this problem or to find this price at which tickets will be solved to give us zero revenue, we must equate the given function for the revenue to 0 and find the value of p, the price of the tickets that make the function to be equal to 0.

For the theatre to make $0 in revenue, this means f(p)=0.

Therefore, we will equate f(p) to 0

Step 2

Equate f(p) to 0

\begin{gathered} 0=150p-5p^2 \\ p(150-5p)=0----(\text{factorize)} \\ p=0 \\ 0r \\ 150-5p=0 \\ 150=5p \\ \frac{5p}{5}=\frac{150}{5} \\ p=30 \\ p=0\text{ or 30} \end{gathered}

Therefore the revenue to be zero, the price of the ticket will be $0 or $30 but the question asked us how high the ticket price will be to get a revenue of 0. Both 0 and 30 gave us revenue of 0 but $30 is higher therefore, the answer will be $30.

Check;

\begin{gathered} 150p-p^2=0 \\ \text{If the price of tickets=0} \\ 150(0)-5(0^2)=0 \\ \text{If p=30} \\ 150(30)-5(30^2)=4500-4500=0 \end{gathered}

Both give us 0 revenue but $30 is higher and the right answer.

Step 3

The equation you can write for revenue of $700 is;

\begin{gathered} 700=150p-5p^2 \\ 5p^2-150p+700=0_{} \end{gathered}

Answer:

50

Step-by-step explanation:

180-(x+80) + 180-(2x+20) = 180 -70

180-x-80 + 180-2x-20 = 110

100-x + 160-2x = 110

260 - 3x = 110

-3x = -150

x = <u>50</u>
