- 3(z+5)=12arrow_forwardIron Sports have been tracking the sales of boxing bags fora number of weeks. Due to problems with production, Iron Sports produce less boxing bags. This results in sales decreasing by 10% each week. In the first week, the company earns $1500 from the sale of boxing bags. (a) How much money does the company earn from boxing bag sales in week 3? $ (b) Which formula could be used to find the total of this sequence for 4 weeks? a(1-r") Sn = [2a + (n – 1)d] S. = 1-r 1-r A 8 of 13 回MOOKO回口回E Select the correct answer: (c) Determine the total amount of money earned from boxing bag sales after 4 weeks. Give your answer to 2 decimal places. $ (d) After how many weeks will the total money earned from boxing bag sales be greater than twice the amount of money earned in the first week? 回RODROO和回 Complete the following: Total money earned > 回回口回券回回口口口E n = weeks.arrow_forward7. Find K when, P(x) = 3x³ - 7x² + kx - 2 D(x) = x + 2 R=-64 8. Find K when, P(x) = 2x³-x² - kx - 6 D(x) = x - 2 R = -20 9. Find K when, P(x) = x³ - kx² - 7x + 10 D(x) = x - 2 R = - 12 10. Find K when, P(x) = kx² - 2x + 1 D(x) = x + 2 R = 25arrow_forward
- 3) Personal taxes Suppose that the percent of total personal income that is used to pay personal taxes is given by y = 0.034x² – 0.044x + 12.642 where x is the number of years past 1990 (Source: Bureau of Economic Analysis, U.S. Department of Commerce). (a) Verify that x = 7 is a solution of 14 = 0.034x² – 0.044x + 12.642. (b) Find the year or years when the percent of total per- sonal income used to pay personal taxes is 14.arrow_forward4.
