The population of the bacteria after 7 hours is 230 bacteria.
An exponential function is given by:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the population of bacteria after x hours.
Given that he starts his experiment with 200 bacteria, hence
a = 200
The bacteria grow at a rate of 2% per hour, hence:
b = 100% + 2% = 1.02
The exponential equation becomes:
y = 200(1.02)ˣ
After 7 hours:
y = 200(1.02)⁷ = 230
The population of the bacteria after 7 hours is 230 bacteria.

Answer:
False
Step-by-step explanation:
y = 2x + 1
Substitute the point (4,3) into the equation and see if it is true
3 = 2(4) +1
3 =8+1
3 =9
This is false, so the point is not a solution
Ans is 392 mm and approx 400mm as perimeter of semi circle is pi r which is 22/7*16 + 40 mm which is the total of the two side of the triangle given.
