Answer:
B) The population is increasing by 102.2% each year.
A) 720,500 represents the initial amount of people in January 1980 and 1.022 represents the increase factor that multiplies to the amount.
Step-by-step explanation:
1.022 times 100 equals 102.2% (a number in the decimals place times 100 give you the percent).
Sin J = cos K
sin J = cos (90 - J)
So, K = 90 - J
Therefore, 60 deg, 30 deg satisfy the condition sin J = cos K.
