Phillipa is a scientist who grows yeast cells. She starts her experiment with 700 yeast cells and notices the growth rate of the
musickatia [10]

Answer:

  1. 700 initial cells
  2. 2486 cells after 25 hours

Step-by-step explanation:

#1 There are 700 yeast cells when Phillipa starts her experiment. (This value is given in the problem statement.)

__

#2 For this, we must assume the time period that is associated with the 5.2% growth. (The problem statement does not specify it.)

The general form of the equation for exponential growth is ...

  f(t) = (initial value)×(growth multiplier in time period)^(number of periods)

When the growth (or decay) rate is indicated as a percentage (r), the "growth multiplier in time period" is generally ...

  growth multiplier = 1+r

Here, the value of "r" is 5.2% = 0.052, so the growth multiplier in the time period is ...

  1 + 0.052 = 1.052

__

As we said, the time period is not specified. Since the only time period mentioned in the problem is 25 hours, we might reasonably assume that the 5.2% growth occurs in one hour. Then the cell population is ...

  f(t) = 700×1.052^t . . . . . . for t in hours

After 25 hours, ...

  f(25) = 700×1.052^25 ≈ 700×3.55135 ≈ 2485.9 ≈ 2486

The number of yeast cells present after 25 hours is about 2486.

Sonbull [250]
Your wording amounts to the equation
4*sqrt(x)+2=-16
4*sqrt(x)=-18
sqrt(x)=-9
but square roots are nonnegative so no solution exists.
