Let set C = {even numbers between 1 and 99} and set D = {0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130}. What is CAD? (2 points)
O {10, 20, 30, 40, 50, 60, 70, 80, 90}
{10, 20, 30, 40, 50, 60, 70, 80, 90, 100}
{all even numbers between 1 and 99>
{numbers between 0 and 100 that are evenly divisible by 10}

What is the result of the following division?

Select the correct answer. what is the exact value of sin (157.5°)? a. 'sqrt(2 - sqrt(2))/2 b. *"-"'sqrt(2 + sqrt(2))/29 c.'sqrt(2 + sqrt(2))/4" d. "-"sqrt(2 + sqrt(2))/4)

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
