I put a picture of the lines graphed on the graph.
I hope this helps and have a great day.
Answer:
(a)Jacob: 256 dandelions
(b)Jessica: 256 dandelions
Step-by-step explanation:
Jacob discovers that the growth over t weeks can be defined by the function:
![f(t)=8\cdot 2^t](https://tex.z-dn.net/?f=f%28t%29%3D8%5Ccdot%202%5Et)
Jessica finds that the growth function over t weeks is defined by the function:
![g(t)=2^{t+3}](https://tex.z-dn.net/?f=g%28t%29%3D2%5E%7Bt%2B3%7D)
After 5 weeks:
Number of Jacob's dandelions
![f(t)=8\cdot 2^t\\=8\cdot 2^5\\=8*32\\=256](https://tex.z-dn.net/?f=f%28t%29%3D8%5Ccdot%202%5Et%5C%5C%3D8%5Ccdot%202%5E5%5C%5C%3D8%2A32%5C%5C%3D256)
Similarly,
Number of Jessica's Dandelions
![g(t)=2^{t+3}\\=2^{5+3}\\=2^8\\=256](https://tex.z-dn.net/?f=g%28t%29%3D2%5E%7Bt%2B3%7D%5C%5C%3D2%5E%7B5%2B3%7D%5C%5C%3D2%5E8%5C%5C%3D256)
After 5 weeks, Jacob and Jessica will have an equal number(256) of Dandelions.
You can not "solve" this, so to speak, rather simplify this expression. Take the "2" and multiply that by the "a" and the "3" in the parentheses. You will then have the simplified answer of: 2a times 6.
Hope that helps!
