The scale of a map says that 4 cm represents 5 km. What actual distance (in kilometers) is represented on the map as 1 centimeter? Write in decimal form.

Tori examined the pattern of exponents in the table. based on the pattern, which statements are true? check all that apply.

(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.

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots
