Question 1

Question Ball TossThrow the ball at a number then answer that question.Question 1As a fundraiser, the band is selling cookies. The cost to make each cookie can be written as c(x) = 0.25x + 0.5 and the functions that represents the amount they sell the cookie for can be written as s(x) = 2x. What function represents the profit, P(x), for each function? A)P(x) = 0.5x + 1 B)P(x) = 0.5x2 + x C)P(x) = 2.25x + 0.5 D)P(x) = 1.75x - 0.5 Question 2Which explicit rule describes the sequence below? 1, 7, 13, 19, 25an = 6n +1an = -6n + 1an = 6n -5an = -6n + 5

Question 3You are planning a vacation. The hotel you are going to stay at charges $129 per night. This can be represented by the function p(h) = 129h. The car rental company charges a $50 insurance fee plus $79 per day. This can be represented by the function p(c) = 50 + 79c. Write a function p(v) to represent the total charges for your hotel and car rental. A)p(v) = 258v B)p(v) = 50 + 208v C)p(v) = 129(79v + 50) D)p(v) = 50(129h + 79c) Question 4Find the 10th term in the sequence

none of the above

Question 5Find the sixth term of the geometric sequence

a)b) c)d)

Question 6Determine the common ratio and find the next three terms of the geometric sequence1, -2, 4, -8, r = 2, a5 = 16, a6 = 32 a7 = 64 r = -3, a5 = -11, a6 = -14, a7 = -17r = -2, a5 = 16, a6 = -32 a7 = 64r = 3, a5 = -5, a6 = -2, a7 = 1

Question 7Adam earns $75 per week mowing lawns. This can be represented by the function f(x) = 75x. Each week he deposits this money into his bank account. At the beginning of January his bank account had a balance of $500 in it. Adam also makes a $45 withdrawal each week. The withdrawals from his account can be represented by the function f(x) = 500 - 45x. Write a function that can be used to represent his bank balance after n months, including his monthly deposit and withdrawal. A)f(n) = 500 - 30n B)f(n) = 500 + 30n C)f(n) = 12(500-30n) D)f(n) = 500 - (75n-45n) Question 8Question 9Which explicit rule describes the sequence below? 1, 7, 13, 19, 25an = 6n +1an = -6n + 1an = 6n -5an = -6n + 5

Question 10Write an explicit rule for the sequence 4, 12, 36, 108,

Question 11A function that can be used to model the cost of producing x t-shirts is c(x)= 10 + 7x, and the function that can be used to model the amount of money to be made from selling x t-shirts is m(x) = 20x.

Write a function p(x) to represent the total profit of selling x number of shirts. Question 12Which sequence is not geometric? Explain why. 3,6, 12, 24,.7,5, 3,1,.1,2,4,8,..27,9,3,1,.
