Find the coordinates of P such that P divided the line segment from A(1, 3) to B(8,4)
into a 4:1 ratio.

(Suggestion: graph points A and B on paper)
a) P17, 1)
b) P(-4.6, 2.2)
c) P(1.8, 8.6)
d) P(6.6, 3.8)

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.

700 miles the train takes 5 hours to a travel the distance at what unit rate is the train traveling?

D. in a discrete probability distribution, the sum of the probabilities for the discrete variables will be > 1. true or false
