Food poisoning occurs when bacteria like salmonella and listeria grow on food. these microorganisms grow at an exponential rate. when an initial population of 100 bacteria are left at 98.6f, they will grow at a rate of y=100(8)^h. which graph could be used to calculate the number of bacteria after a certain number of hours?

The third graph is correct

Step-by-step explanation:

The exponential growth function is given as;

y=100(8)^h

To determine which graph represents the above function, we can evaluate the value of y when h = 0, 1, and 2 .

When h = 0, y=100(8)^0 = 100

when h = 1, y=100(8)^1 = 800

when h = 2, y=100(8)^2 = 6400

Therefore, the graph should be exponential and have these set of points;

(0, 100) , (1, 800), (2, 6400)

The third graph meets the criteria

Step-by-step explanation:

Note that y=100(8)^h = 100 at time h = 0.  The correct graph is the one that shows y = 100 at h = 0.  That's the second graph.  The graph through (0, 1000) is incorrect.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
