-3 + y = 0
All you need to do is add 3 to both sides so that the -3 cancels out on the left side. Doing this will also leave you with the variable y on the left side.
and tell me what you believe the answer is<span />

A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rat

oksano4ka [1.4K]

<u>Answer-</u>

<em>The insect population at the end of week 11 is </em><em>1730</em><em>.</em>

<u>Solution-</u>

A population of insects grows exponentially.

The general form of exponential function is,

$y=ab^x$

Where,

a, b are constants.

Putting the data given in the table, in the the equation in order to get the values of a, b

At (0, 20)

$\Rightarrow 20=ab^0$

$\Rightarrow a\cdot (1)=20$

$\Rightarrow a=20$

Now the exponential function becomes,

$y=20b^x$

At (1, 30)

$\Rightarrow 30=20b^1$

$\Rightarrow 20b=30$

$\Rightarrow b=\dfrac{30}{20}$

$\Rightarrow b=\dfrac{3}{2}$

Now the equation becomes,

$y=20(\frac{3}{2})^x$

For calculating the number of insects at the end of the 11th week, putting x=11, so

$y=20(\frac{3}{2})^{11}$

$=1729.95 \approx 1730$
