In which quadrant does the terminal side of the angle -230° lie?
quadrant i
quadrant ii
quadrant iii
quadrant iv

The Given angle is -230° i.e negative 230°

Therefore lies in second quadrant which is between -180° to -270°

Step-by-step explanation:

For angle to move in ANTICLOCK WISE ( positive angles):

In anticlockwise the terminal side of the angle is moving from first quadrant to second quadrant then to third quadrant then to fourth quadrant and so on.

Quadrant I = 0 to 90°

Quadrant II = 90° to 180°

Quadrant III = 180° to 270°

Quadrant IV = 270° to 360°

For angle to move in CLOCK WISE ( negative angles):

Here, the negative sign tells us we're moving in a clockwise direction, so from the positive x-axis, down into fourth quadrant then to third quadrant then to second quadrant then to first quadrant and so on.

Quadrant IV =  0 to -90°

Quadrant III = -90° to -180°

Quadrant II  = -180° to -270°

Quadrant I   = -270° to -360°

The Given angle is -230° i.e negative 230°

Therefore lies in second quadrant which is between -180° to -270°

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
