Vince borrows $900 to buy a couch. he will pay off the loan by paying 1.5% simple interest for 2 years. vince incorrectly calculates the amount he will pay back using the expression below. 900 + 900(1.015 • 2) what is the correct amount vince will pay back altogether? explain the error in vince’s expression.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
