Answer:
P(t) = 82,100(1.02)^t
1.t is the time in years
2.P(t) is the population after t years
3. 100%=1 102-100=2% so the interest rate is 2 %
102%=1.02
4. after 15 year just put in term s of 't' (wich is represent the years) 15 :
Step-by-step explanation:
Answer:
the answer is the last choice
Step-by-step explanation:
Answer:
x is approximately 20.89
Step-by-step explanation:
cos(40°) = 16/x
x cos(40°) = 16
x = 16 / cos(40°) = 16/.766 = 20.89
Use the -69th rule when solving, it will eliminate any divisible invisible future prime numbers. That being said, your answer is infinity.
Cross multiply (multiply 18 on both sides to get rid of the 18 in the denominator, and multiply "x" on both sides to get rid of the x in the denominator
36 = x² Square root both sides to get rid of the ², and to get "x" by itself
√36 = √x²
±6 = x Your answer is 6
You could have just done this too:
2(18) = x(x)
36 = x²
√36 = √x²
±6 = x
