Answer:

#3: 81

Step-by-step explanation:

I haven't done this type of math in a while so I'm unsure about #1 and #2, but #3 is 81.

3^4 = 3 × 3 × 3 × 3

3^4 = 9 × 3 × 3

3^4 = 27 × 3

3^4 = 81

A particular type of cell increases by 75% in number every hour. Find the number of cells present at the end of 12 hours if ther
prisoha [69]

We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.

We will use exponential growth formula to solve our given problem.

y=a\cdot (1+r)^x, where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

75\%=\frac{75}{100}=0.75

Upon substituting initial value a=4 and x=12 in above formula, we will get:

y=4\cdot (1+0.75)^{12}

y=4\cdot (1.75)^{12}

y=4\cdot 825.0050068497657776

y=3300.020027

y\approx 3300

Therefore, there will be approximately 3300 cells at the end of 12 hours.
