Question

Given that P = (5, 9) and Q = (13, 12), find the component form and magnitude of PQ.
helppp please

Answer 1

first, PQ = vector q - vector p = (13,12) - (5,9) = (8,3)
the magnitude of PQ = absolute(x^2+y^2)
just put x=8 and y=3

Answer 2

can i ask anither question. Two forces with magnitudes of 150 and 75 pounds act on an object at angles of 30° and 150° respectively. Find the direction and magnitude of these forces. Round to two decimal places in all intermediate steps and in your final answer.

Answer 3

do i use the law of cosines?

Answer 4

i think you can use the law of cosine

Answer 5

to find c\[^{2}\] and what angle would i use?

Answer 6

?

Answer 7

ahm wait i need to check it first
