Tadeo is a beekeeper. The table shows the weekly number of bees producing honey in a new hive. Which expression gives the number
Afina-wow [57]

The exponential equation that gives the number of bees in week 12 is of:

y = 4(3)^{11} = 708588

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

It is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the rate of change.

In this problem, considering that the initial week is the first, and the value triples every week, the expression for the number of bees after x weeks is given by:

y = 4(3)^{x - 1}

Hence, after 12 weeks, the expression is:

y = 4(3)^{11} = 708588

Which ratio is equivalent to 9/36
balandron [24]

Answer:

1/4

Step-by-step explanation:

Step 1: Find the GCF. List out the factors of the numerator and the denominator. 1, 3, 9 are the factors of 9, while 1, 2, 3, 4, 6, 9, 12, 18, and 36 are the factors of 36. 9 is a common factor of both of them, so the GCF is 9.

Step 2: Divide the numerator and denominator by 9 (the GCF). 9/9 is 1. 36/9 is 4. This means that our fraction is 1/4. The fraction is in simplest form.
