Answer: I think the answer is D
Step-by-step explanation:
that's very interesting!! is there more to your question that we can answer?
Answer:
![Y'(t) = 0.025e^{-0.001t}](https://tex.z-dn.net/?f=Y%27%28t%29%20%3D%200.025e%5E%7B-0.001t%7D)
Step-by-step explanation:
The derivative of a constant multiplied by a function is the constant multiplied by the derivative of the function.
So
![(a*f(x))' = a*f'(x)](https://tex.z-dn.net/?f=%28a%2Af%28x%29%29%27%20%3D%20a%2Af%27%28x%29)
If we have an exponential function, in the following format:
![f(x) = e^{ax}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20e%5E%7Bax%7D)
The derivative is:
![f'(x) = a*e^{ax}](https://tex.z-dn.net/?f=f%27%28x%29%20%3D%20a%2Ae%5E%7Bax%7D)
In this problem, we have that:
![Y(t) = 25e^{-0.001t}](https://tex.z-dn.net/?f=Y%28t%29%20%3D%2025e%5E%7B-0.001t%7D)
The derivative is
![Y'(t) = -0.001*25e^{-0.001t} = 0.025e^{-0.001t}](https://tex.z-dn.net/?f=Y%27%28t%29%20%3D%20-0.001%2A25e%5E%7B-0.001t%7D%20%3D%200.025e%5E%7B-0.001t%7D)
Answer:
X=9 and Y=81
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
start by setting angle a equal to angle b
next add 21 to the opposite side
then subtract 2x from the opposite side
finally you're left with x=8
