Consider the following system of equations. 1.75x + 1.25y = 2.75
7x + 5y = 9

What is the solution to the system?

Since 11 ≠ 9, there is no solution.

Since 0 = 0, there are infinitely many solutions.

There is one solution, x = 0 and y = 0.

There are two solutions (11, 0) and (0, 9).

(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.

Which of the following parabolas opens down?

There are four paths from the cabin to the lake. in how many ways can you walk from the cabin to the lake back?
