Answer:
First statement is correct
Step-by-step explanation:
Segment AB is tangent to circle C because
Answer:x=−8 and y=8
Step-by-step explanation: Do you want it solved step by step?
![ln(T- \frac{20}{200})=-0.11t \\ e^{ln(T- \frac{20}{200})}=e^{-0.11t} \\ T- \frac{20}{200} =e^{-0.11t} \\ T-0.1=e^{-0.11t} \\ T=e^{-0.11t}+0.1](https://tex.z-dn.net/?f=ln%28T-%20%5Cfrac%7B20%7D%7B200%7D%29%3D-0.11t%20%5C%5C%20e%5E%7Bln%28T-%20%5Cfrac%7B20%7D%7B200%7D%29%7D%3De%5E%7B-0.11t%7D%20%5C%5C%20T-%20%5Cfrac%7B20%7D%7B200%7D%20%3De%5E%7B-0.11t%7D%20%5C%5C%20T-0.1%3De%5E%7B-0.11t%7D%20%5C%5C%20T%3De%5E%7B-0.11t%7D%2B0.1)
Then, now that we have solved for T, we can evaluate and solve for t=20 minutes.
Answer:
y= -5x+15
Step-by-step explanation:
the point-slope formula is
![y-y_{1}=m(x-x_{1} )](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%20%29)
where m= slope
plug the given point (4,-5) and slope m=-5 into the formula
![y-(-5)=-5(x-4)](https://tex.z-dn.net/?f=y-%28-5%29%3D-5%28x-4%29)
simplify and distribute
![y+5=-5x+20](https://tex.z-dn.net/?f=y%2B5%3D-5x%2B20)
subtract 5 from both sides
![y=-5x+15](https://tex.z-dn.net/?f=y%3D-5x%2B15)
