Where the pic or question?
1). 2x-1=5 (cause x can really be anything) solve the equation to get x=3 or in this case, triangle = 3.
2). Using the info from above, we get the equation 3+x=1.
Solving this equation we get, x (square) =-2.
3). Using all the info from the above problems we get the equation: 3-2*-2=x
Solving that we see that x (star) equals 7.
In conclusion:
Triangle=3
Square=-2
Star=7
Those are two different types of measurments :) are you sure you typed it correctly?
Given:
The growth of a sample of bacteria can be modeled by the function
![b(t)=1001.06t](https://tex.z-dn.net/?f=b%28t%29%3D1001.06t)
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
![b(t)=1001.06t](https://tex.z-dn.net/?f=b%28t%29%3D1001.06t)
where, b is the number of bacteria and t is time in hours.
Substituting t=3, we get the number of total bacteria after 3 hours.
![b(3)=1001.06(3)](https://tex.z-dn.net/?f=b%283%29%3D1001.06%283%29)
![b(3)=3003.18](https://tex.z-dn.net/?f=b%283%29%3D3003.18)
Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.
![b(3)\approx 3003](https://tex.z-dn.net/?f=b%283%29%5Capprox%203003)
Therefore, the number of total bacteria after 3 hours is about 3003.
The total surface area of the cylinder would be 748 sq inches. I have attached a picture of the work in case you need it. I hope this helps. :)
