Step-by-step explanation:
Answer:
5 th day
Step-by-step explanation:
Given :
1st day :
Time = 30 seconds
Time increases by 20% each day :
2nd day = 20% * 30 = (1.20 * 30) = 36 seconds
3rd day = 1.20 * 36 = 43.2 seconds
4th day = 1.20 * 43.2 = 51.84 seconds
5th day = 1.20 * 51.84 = 62.208
First day Aretha hold a plank for over 1 minute is the 5th day
Given:
amount borrowed $6,100
interest rate 6% - assuming annual interest rate
term - 290 days of a 365 day year.
This is a simple interest computation.
Interest = Principal * interest rate * term
Interest = 6,100 * 6% * 290/365
Interest = 290.79
Total payment at the end of the 290 term would be $6,390.79.
Principal + interest → 6,100 + 290.79 = 6,390.79
Answer:
B. f-1(x) = (5/2) x - 6.
Step-by-step explanation:
f(x) = (2x + 12) / 5
5 f(x) = 2x + 12
2x = 5 f(x) - 12
x = (5 f(x) - 12) / 2 ow replace the x by f-1(x) and f(x) by x:
f-1(x) = ( 5x - 12)/ 2
f-1(x) = (5/2) x - 6.
