A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria. How many bacteria will there be on
spayn [35]

In this question, it is given that

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.

And we have to find number of bacterias on day *.

For that we use the following formula

N(t) =N_{0} (1 +r)^t

N(0)= 420, r = 0.18 , and \ t = 8days

Substituting these values in the formula, we will get

N(8)= 420(1+0.18)^8
\\
N(8)=1579

THerefore on day 8, number of bacterias are 1579.

I need some helppp people

We can observe that the function describing the graph is linear and so the equation is of linear nature:

y=mx+n

Numbers m and n have special names. m is called the slope, n is called y-intercept.

From the graph one can tell that the line intercepts y-axis at y = -1 that means n = -1. What about the slope you say?

The slope can be calculated using two points' coordinates that lie on the line:

m=\frac{\Delta y}{\Delta x}=\frac{-1-5}{0-5}=\frac{6}{5}

Now our line has an equation,

y=\frac{6}{5}x-1

Hope this helps.
