Ascientist runs an experiment involving a culture of bacteria. she notices that the mass of the bacteria in the culture increases exponentially with the mass increasing by 260% per week.

what is the 1-week growth factor for the mass of the bacteria?

what is the 1-day growth factor for the mass of the bacteria?

by what percent does the mass of bacteria increase by each day?

if the mass of the bacteria instead increased by 474% per week, by what percent would the mass increase by each day?

why can't you?

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

using pemdas, (order of operations) you'll see the answer is 24.
