the area covered by a certain population of bacteria increases according to a continuous exponential growth model. suppose that a sample culture has an initial area of and an observed doubling time of hours. (a)let be the time (in hours) passed, and let be the area of the sample at time . write a formula relating to . use exact expressions to fill in the missing parts of the formula. do not use approximations. (b)what will the area of the sample be in hours

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

the five is the numerator
