Answer:
the answer is B because 3x4 is 12
The formula is
A=p (1-r)^t
A future value?
P current value 42000
R rate of decreases 0.08
T time 6 years
A=42,000×(1−0.08)^(6)
A=42000 (0.92)^6
A=25,466.91 round your answer to get 25467
Hope it helps!
A) f(x) is decreasing because the base is less than 1.
0.56 is close to 0.5, so its like saying that you are taking half each time, therefore the value is getting smaller.
g(x) is increasing because the base is greater than 1.
you are multiplying by 4 each time, making the value bigger.
B ) The y-intercept is where x=0.
Anything to the '0' power is 1. Therefore the y-intercept is equal to the coefficient in front of each function.
f(x) = 3 , g(x) = 6
C) Just plug in x=4 to each function in a calculator.
f(4) = 0.295
g(4) = 1536
That would be 8 1/6 * 4/7 = 49/6 * 4/7 = 7*4 / 6 = 28/6 = 4 4/6 = 4 2/3
Answer is 4 2/3 hours
If you take 3/4 and times 4 by two you get 8 , if you do the same to 3 you get 6 , you then have 6/8 and that's clearly more than 1/8 .
