Use a multiple regression model with dummy variables as follows to develop an equation to account for seasonal effects in the data. qtr1 = 1 if quarter 1, 0 otherwise; qtr2 = 1 if quarter 2, 0 otherwise; qtr3 = 1 if quarter 3, 0 otherwise. if required, round your answers to three decimal places. for subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (example: -300) if the constant is "1" it must be entered in the box. do not round intermediate calculation.

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test
