Answer:
to be fair, i really dont know this
Step-by-step explanation:
Answer:
- It is a function
- Domain: {-4, -2, 1, 5}
- Range: {-9, -7, -4, 5}
Step-by-step explanation:
A function is defined so that for each input (known as the domain), there is no more than one output (known as the range).
<em>Answer:</em>
<em>There would be 173,535 lionfish after 6 years.</em>
<em>Step-by-step explanation:</em>
<em>Since lionfish are considered an invasive species, with an annual growth rate of 67%, ya scientist estimates there are 8,000 lionfish in a certain bay after the first year, A) to write the explicit equation for f (n) that represents the number of lionfish in the bay after n years; B) determine how many lionfish will be in the bay after 6 years; and C) if scientists remove 1,200 fish per year from the bay after the first year, determine what is the recursive equation for f (n); the following calculations must be performed:</em>
<em></em>
<em>A)</em>
<em>8000 x 1.67 ^ n = f </em>
<em>B)</em>
<em>8000 x 1.67 ^ 6 = X</em>
<em>8000 x 21.691961596369 = X</em>
<em>173,535.692770952 = X </em>
<em>C)</em>
<em>(8000 - 1200 x 1 ^ n) x 1.67 ^ n = f</em>
<em>Therefore, there would be 173,535 lionfish after 6 years.</em>
Answer:
x = -2
Step-by-step explanation:
f(x)= 5(x-2)
since, f(x)= -20
-20 = 5(x-2)
x-2 = -20/5
x = - 4 + 2
x = -2
The answer would be 5,875.00
