Now change matrix b to a 3 x 3 matrix and enter these values for b:
b = 1.2 1.4 3.1
[2.2 1.1 5.6]
3.7 4.2 6.7
then select a • b to calculate the product:
77 39 −33
1.2 1.4 3.1
[2.2 1.1 5.6=c11 c12 c13]
3.7 4.2 6.7
c11 =
c12 =
c13 =

Asailor is looking at a kite. if he is looking at the kite at an angle of elevation of 36and the distance from the boat to the point where the kite is directly overhead is 40 feet, how high is the kite?

Which is the solution to the inequality? 2 3/52 1/15 b< 3 2/15 b> 3 2/15

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.
