PLS HELP!!! After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. You notice the rainbow is
the shape of a parabola.
The equation for this parabola is y = -x^2 + 36.

1.) What is the domain and range of the rainbow? Explain what the domain and range
represent. Do all of the values make sense in this situation? Why or why not?

2.) What is the x- and y-intercepts of the rainbow? Explain what each intercept represents.

3.) Is the linear function you created with your table positive or negative? Explain.

4.) What are the solutions or solution to the system of equations created? Explain what it or
they represent.
(Please don’t answer if you don’t know I really need help ) <3 thank you!

step-by-step explanation:

idk

step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck
