Answer:
168 is the change in population
Step-by-step explanation:
well if u think about it all u really have to do is take 28×6 and it would help u find the change in population
Answer: bacteria 2
Step-by-step explanation:
Since the growth rates are modeled as : Bacteria 1: y = 4x
And Bacteria 2: y = 4x2
Where y represents the number of bacteria colonies and x represents the number of hours.
Let's plug in for the two models
By assuming x = 2 and x = 3
If x = 2
Bacteria 1 will be y = 8 and bacteria 2 will be y = 16
Based on these models, bacteria 2 is growing faster than bacteria 1 because the growth is exponential
Ok so the best way to solve this problem is to simplify it as small as possible so first with the given equation 6(x+7)+3x you need to use the distributive property on 6(x+7)
This should get you 6x + 42
Then you have to add everything with like terms (or everything with the variable x) So add together 6x + 3x and that should get you 9x
So now you are left with
9x + 42 which is C
Hope this helps :D
Notice, it hits the ground when d = 0, thus

that's when.
as far as its graph, is more or less like the picture below, now, notice that if we put the quadratic in "vertex form", it'd look like

so its vertex is at (0, 55), so just pick one point to the left of the vertex, and one to the right of the vertex, and draw it away
