Best ResponseYou've already chosen the best response.1So, you have 3 points: (2,1) (3,3) (4,9) what these points mean, is that \(\large\color{black}{ \displaystyle a_2=1 }\) \(\large\color{black}{ \displaystyle a_3=3 }\) \(\large\color{black}{ \displaystyle a_4=9 }\)

Best ResponseYou've already chosen the best response.0the options are an=1/3(27)^n1 an= 27(1/3)^n1 an= 1/3(3)^n1 an= 3(1/2)^n1

Best ResponseYou've already chosen the best response.1yes, it is the third one. (not because of the pattern that i told you, but because of the pattern that you noticed)

Best ResponseYou've already chosen the best response.0Jeff is designing the seating arrangement for a concert in his high school theater. To give everyone a good view, each row must have 5 more seats than the row before it, and the 1st row can only have 12 seats. Help Jeff plan the rest of the seating by solving for how many seats are in row 25. Then explain to Jeff how to create an equation to predict the number of seats in any row. Show your work, and use complete sentences

Best ResponseYou've already chosen the best response.1So, lets do this piece by piece. `each row has 5 more seats than the row before it` \(\large\color{black}{ \displaystyle \left(a_{n+1}\right) =\left(a_1\right)+5 }\) `and the first row can only have 12 seats.` \(\large\color{black}{ \displaystyle a_{1}=12 }\) `help Jeff plan the rest of the seating by solving for how many seats are in row 25` find \(\large\color{black}{ \displaystyle a_{25} }\)

Best ResponseYou've already chosen the best response.1lets, see... based on the first statement we know the common difference is 5. (that is d=5) \(\large\color{black}{ \displaystyle a_{n}=a_1+5(n1) }\) plugging in our information \(\large\color{black}{ \displaystyle a_{25}=12+5(251) }\)

Best ResponseYou've already chosen the best response.1\(\large\color{black}{ \displaystyle a_{25}=12+5(251) }\) \(\large\color{black}{ \displaystyle a_{25}=12+5(24) }\) \(\large\color{black}{ \displaystyle a_{25}=12+5(20) +5(4) }\) \(\large\color{black}{ \displaystyle a_{25}=12+100 +20 }\) \(\large\color{black}{ \displaystyle a_{25}=132 }\)

Best ResponseYou've already chosen the best response.0so how do you create an equation

Best ResponseYou've already chosen the best response.0i guess the answer will be Row one= 12 Row two= 12 + 5 The equation will be: Row n = 12+5(n1) Where n is random number, the row will have 12 seats plus 5 for every row higher than 1. So row 25 will have 12 + 5*(251) 12+24*5=12+120=132 Row 25 will have 132 seats.

Best ResponseYou've already chosen the best response.0Tommy has $350 of his graduation gift money saved at home, and the amount is modeled by the function h(x) = 350. He reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)^x − 1. After combining the two functions, his new function is g(x) = 350(1.04)^x − 1. Using complete sentences, explain what this new function means
