Your friend just purchased a new hybrid for $25,236. she received $3,110 for her trade in and used that money as a down payment for the new hybrid car. she financed the vehicle at 12% apr over 48 months. she received a stipend from school and paid off the loan after making 30 payments. use the actuarial method formula and the table above to determine the amount of unearned interest given that her monthly payment is $582.74. a. $1,402.00 c. $933.59 b. $1,230.72 d. $582.74 the answer is c

sine

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
