Roller Coaster Crew

Ray and Kelsey have summer internships at an engineering firm. As part of their internship, they get to assist in the planning of a brand new roller coaster. For this assignment, you help Ray and Kelsey as they tackle the math behind some simple curves in the coaster's track.

Part A

The first part of Ray and Kelsey's roller coaster is a curved pattern that can be represented by a polynomial function.

1. Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only. Is there a way for the both of them to be correct? Explain your answer.

2. Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = (x + 2)(x − 1)(x − 2)
g(x) = (x + 3)(x + 2)(x − 3)
g(x) = (x + 2)(x − 2)(x − 3)
g(x) = (x + 5)(x + 2)(x − 5)
g(x) = (x + 7)(x + 1)(x − 1)

3. Create a graph of the polynomial function you selected from Question 2.

Answer:

~300 times

this is because each turn you have a one out of six chance, simply divide 1800 by 6 and voila there's your answer

Answer:

300 times.

Step-by-step explanation:

Looking at this, we have a 6-space spinner. Each number has a 1/6 chance of being landed on. As a result, all we really need to do is divide 1800 by 6 to get 300 times to get a 2, theoretically.

Anthony is practicing kicking field goals for his high school football team. He knows that the field goal is 10 feet off the ground.

Part A: If he stands 40 feet from the field goal, how far must he kick the ball in order to make the extra point?

Part B: Explain how you arrived at your conclusion.

Answers

Answer: The answer is 41.23.

Step-by-step explanation:

You have to find the hypotenuse of the triangle so we are going to use the formula a^2+b^2=c^2.

The first thing we need to do is substitute 40 and 10 in for a and b which would give you 40^2+10^2.

Next you will multiply 40x40 and 10x10 which gives you 1600+100.

Lastly you want to add these together to get 1700 and then you can just search up square root of 1700 and you get 41.23.

Answer:

The speeds are 88 / 9, 92 / 11, and 96 / 13

Step-by-step explanation:

Since we are already given the equation here, we can plug in the given speeds to find the times. Plugging in 45 will give t = 2 + 350 / 45 which is 2 + 70 / 9. 2 = 18 / 9. We get the time is 88 / 9. Plugging in 55 will give t = 2 + 350 / 55 = 2 + 70 / 11. 2 = 22 / 11. The time is 92 / 11. Plugging in 65 will give t = 2 + 350 / 65 = 2 + 70 / 13. 2 = 26 / 13. The time is 96 / 13.

Answer:

88 -- 9, 92 -- 11, 96 -- 13

PHOTOGRAPHY Joseph subscribes to a website for processing his digital pictures. The subscription is $8 and 5-by-7-inch prints are $0.15 each. How many prints does Joseph purchase if the charge for January is $11?
help now i beg i will give brainlist plz

Answers

The answer is 20 prints.

Explanation:
The total cost is $11. Joseph paid $8 for the SUBSCRIPTION (NOT PRINTS) already, so we take away the 8 from 11, equaling in $3 left.
The question is asking for the amount of prints. Now that we only have 3 dollars left, we just divide that by the cost of each print (0.15) to see how many prints can go into that cost.
3 divided by 0.15 is 20. So, Joseph purchased 20 prints.
