You are to make four straight-line moves over a flat desert floor, starting at the origin of an xy coordinate system and ending at the xy coordinates (-154 m, 76 m). The x component and y component of your moves are the following, respectively, in meters: (20 and 60), then (bx and -70), then (-20 and cy), then (-60 and -70). What are (a) component bx and (b) component cy

Step-by-step explanation:

What are (a) component bx and (b) component cy

(c) What is the the magnitude of the overall displacement?

(d) What is the angle (relative to the positive direction of the x axis)?

1(a) component bx

b)component cy

2) Magnitude

we use pythagoras theorem to solve the magnitude of the resultant vector

lastly we use the following trigonometry to solve for θ

= -26.3° going clockwise from the negative x direction

However, it is in the 2nd quadrant , thus from positive x-direction , it would actually be 152°

32

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
