A group of yeast cells grows by 75% every 3hrs. At 9am, there are 200 yeast cells [9 marks].
vodomira [7]

a) The exponential function that models the number of cells is: A(t) = 200(1.75)^{\frac{t}{3}}

b) There will be 1292 cells after 10 hours.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^{\frac{t}{n}}

In which:

  • A(t) is the amount after t hours.
  • A(0) is the initial amount.
  • r is the rate of change, as a decimal.
  • n is the time it takes to change.

For this problem, the parameters are:

A(0) = 200, r = 0.75, n = 3.

Hence the equation is:

A(t) = A(0)(1 + r)^{\frac{t}{n}}

A(t) = 200(1 + 0.75)^{\frac{t}{3}}

A(t) = 200(1.75)^{\frac{t}{3}}

The number of cells after 10 hours is:

A(t) = 200(1.75)^{\frac{t}{3}}

A(10) = 200(1.75)^{\frac{10}{3}}

A(10) = 1292.

Complete the table for each value of m. an the table be used to show that the expression are equivalent? explain
kirill [66]

Answer and Step-by-step explanation:

<u>m_| 2(3m + 7) |_6m + 14_|</u>

<u>1    |      20       |       20     |</u>

<u>2   |      26       |       26     |</u>

<u />

<u />

<u />

<u>This table can be used to show that the expression are equivalent because every time the variable was plugged in, the output was the same for both equations.</u>

<u />

<u>Also, the first equation is the undistributed version of the second equation.</u>
