Principal Harris has decided to install lockers for each of the 550 students at High Tech High. The lockers are to be numbered 1 – 550. When High Tech High students return from summer vacation next year, they decide to celebrate the lockers by working off some energy. The first student goes to all the lockers and opens them. The second student goes to every second locker and shuts it. The third student goes to every third locker and changes the state of it (If it was open close it, if it was closed open it). This pattern continues all the way up to the 550th student. 

Answer the following questions:

1. Look at the first 10 lockers. After the first 10 students, which ones are still open? 

2. Now look at ALL of the lockers. After everybody has been marching around the school, which lockers are closed and which ones are open? 

3. If the students were not in order when they went marching, would the same lockers still be closed/open?

A small company is a selling a new board game, and they need to know how many to produce in the future 

After 12 months , they sold 4 thousand games , after 18 months they sold 7 thousand games , and after 36 months they sold 16 thousand games. 

Could this information be reasonably estimated using a single linear model ?

If so use the model to estimate the number of games sold after 48 months . If not explain your reasoning

Mr. Saldariega has a vacant lot in his backyard. He wants to make as many rectangular gardens as possible such that the length of each garden is 2 m longer than its width. He also wants the garden to have a maximum area of 48 m².

a. If we let w be the width, what is the expression of the length in terms of w based on the problem?

b. If the formula for the area of a rectangle is A = lw, express the quadratic inequality in terms of width (w).

c. What is the solution set of the quadratic inequality?

d. Based on the solution set, how many rectangular gardens he can make if the length must be in whole number?​

I am working in Eureka Math Algebra 1 module 3 lesson 9 and my teacher gave me this word problem:

Sequences are functions. The domain is the set of all term numbers (which is usually the positive integers), and the range is the set of terms of the sequence. For example, the sequence 1, 4, 9, 16, 25, 36, … of perfect squares is the function:

let : {positive integers} → {perfect squares} Assign each term number to the square of that number.

a. What is (4)? {Type your answer as f(4)= with no spaces}

and i can’t figure out to do it.
