The fraction of the surface area of a pond covered by algae cells double every week. Today, the pond surface is fully covered with algae. This situation can be modelled C= (1/2)^t, where C is the fraction of the surface area covered by algae t weeks ago. When was 25% of the pond covered?

i have no idea just need points sorry

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:

its kinda hard to answer this when we dont have all the information that we need.

answer: i ! the answer is   9000 seconds, also d

hope i
