I need for my 5 th class son for the calculated answers and explained thanks. Thursday 00:0970 00:0 780

Matt Tom Two boys timed their race from the classroom door to the end of the building.

1. The school record is 6:90. Tom is still seconds behind the record.

2. The time difference between Matt and Tom is seconds.

(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.

Enter the number of complex zeros for the polynomial function f(x) = x 4+ 5x² +6

In the geometric progression –3, 12, −48… what term is 3,072?
