Answer:
A 8
Step-by-step explanation:
g(2)= x+2x2 = 8
Answer:
x = 13
Step-by-step explanation:
Combine like terms:
3/5x (x + 2 ) = x - 4
3/5x + 6/5 = x - 4
<u>-x -x</u>
-2/5x + 6/5 = -4
<u>- 6/5 -6/5</u>
-2/5x = -26/5
divide everything by -2/5
Your final answer should be 13.
You can double-check by substituting 13 into the original equations.
Answer:
506
Step-by-step explanation:
The count is multiplying by 1.5 each day, so after 4 days, it will have multiplied by 1.5^4 = 5.0625
Then the count is predicted to be ...
100·5.0625 ≈ 506.25
The count will be 506 after 4 days.
Since the rate is constant, the growth of the height of the helicopter follows a linear pattern. The helicopter has an initial quota of 40ft, so that would be the constant term. The linear terms's coefficient is the rate of growth, so 21 ft/s. So, if is the number of seconds passed from when the observation started, we have
Which means that, if , the height is
The answer is A.1.06^5t/1.06^2t
