According to the graph what is the value of the constant in the equation below ?

3.2

Step-by-step explanation:

Given Height = constant * width

So constant = Height / width

Now we use the point on the graph and find out constant

Lets take (0.5,1.6)

Here width =0.5  and height = 1.6

Lets check with one more point (1,3.2)

Here width =1  and height = 3.2

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
