1st) 275+70-50 Lastly: Subtract -350 - 295 = - 55
275+70 = 345 The answer is - 55
345 - 50 = 295
The equation will be of the form:
![A(t)= A_{0} e^{rt}](https://tex.z-dn.net/?f=A%28t%29%3D%20A_%7B0%7D%20e%5E%7Brt%7D)
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
![40=320e^{3r}](https://tex.z-dn.net/?f=40%3D320e%5E%7B3r%7D)
Rearranging and taking natural logs of both sides, we get:
![ln\ 0.125=3r](https://tex.z-dn.net/?f=ln%5C%200.125%3D3r)
![r=\frac{ln\ 0.125}{3}=-0.693](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bln%5C%200.125%7D%7B3%7D%3D-0.693)
The required model is:
Answer:
i think it is Rewrite in Standard Form y=2x+5. y=2x+5 y = 2 x + 5.
