An array is a visual drawing to be used in multiplication problems. For example; 1 × 2 is 2 and you draw it or visualize it like; 00
So the answer to your question would be...
000000000
000000000

000000000
000000000
000000000
000000000
000000000
000000000
000000000

The top is the array of how it would look like to your answer tour question. Also, another way to do this is (2 + 5) × 9 = 63 
And yasss your answer is 63.... ALSO

***!!! PLEASE give this a THANKS! ALSO the BRAINIEST ANSWER/QUESTION! :) :D =P =) =D

28. sylvia researched changes in the deer population in her state's parks during her lifetime
kifflom [539]

Using an exponential function, it is found that it will take 24 years for the current population of 4800 deer to reduce to 600.

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

An exponential function is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the rate of change, as a decimal.

In this problem, considering the initial value of 4800, and that the population halves every 8 years, the equation is given by:

A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}

The population will be of 600 when A(t) = 600, hence:

A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}

600 = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}

\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{600}{4800}

\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{1}{8}

\left(\frac{1}{2}\right)^{\frac{t}{8}} = \left(\frac{1}{2}\right)^3

Hence:

t/8 = 3.

t = 24.

It will take 24 years for the current population of 4800 deer to reduce to 600.
