Diameter AC = 26. Find the length of arc AB. Use 3.14 for pi. Round to the nearest tenth.

since the number of degrees in a straight line is 180, we will subtract 140 from that to get 40 degrees for angle AOB. O being the midpoint of the circle. 40/360=1/9. So the length of AB would be 1/9 of the circumfrence of the whole circle. Circumfrence=13^2pi= about 530.9. 1/9 of this is 58.9  ,

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

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.
