1.Given the linear inequality x+2y≤12, what error was made when graphed? 2.The point (5, 4) is not a solution to the inequality. Why? Explain your reasoning using the graph and using algebra.

(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.

Analyze the graph of the cube root function shown on the right to determine the transformations of the parent function. then, determine the values of a, h, and k in the general equation. y=a3x-h+k h= . k= done 000000l o 7 of 8

1) prove that 731^3−631^3 is divisible by 100 2) prove that 99^3−74^3 is divisible by 25
