Answer:

The population reaches 42,336 fish in 2258

Step-by-step explanation:

<u>Given</u><u>:</u>

P =  0.62x^2 - 0.043x + 3

<u>To Find:</u>

Time taken  to reach 42,336 = ?

<u>Solution:</u>

According to the question  x is the number of years after which the population .

Then

42336 = 0.62x^2 - 0.043x + 3

0 = 0.62x^2 - 0.043x + 3- 42333

0.62x^2 - 0.043x -42333 = 0

Solving using quadratic formula

x =\frac{ -b\pm \sqrt{b^2 -4ac}}{2a}

x =\frac{ -(-0.043)\pm \sqrt{(-0.043) -4(0.62)(42333)}}{2(42333)}

x =\frac{ -(-0.043)\pm \sqrt{(0.001849) -0.10664}}{84666}

x=261.337                    x=−261.268

Neglecting the   negative value we get

x = 261.337

x =  261 approx

261 years after  1997  =  2258

4 = -7s - 10<br><br> how do you get -2? please show your work
andreyandreev [35.5K]
First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped

I Have To Find The Mode And Median.Explain What To Do Please
Pani-rosa [81]
To find the mean, add all the numbers, then divide by the amount of numbers there are. I'll do the first one as example.
6+5+6+9+9+11=46. 
46 divided by 6 = 7.66
To find the median, put all the numbers in order from biggest to smallest. 
5, 6, 6, 9, 9, 11.
Since there is an even amount of numbers, you have to add the two middle numbers (6,9) and divide by two. 
6+9= 15
15 divided by 2 = 7.5
To find the mode, you just have to find the most common number. In this case, there are two most common numbers (6,9) so the answer would be both. 
5,6,6,9,9,11
Answer:
Mean: 7.66
Median: 7.5
Mode: 6,9

If f(x) = 2(x - 1) and g(x) =-2x^2<br> find (fºg)(-4)
vladimir1956 [14]

Answer:

- 66

Step-by-step explanation:

Evaluate g(- 4) then substitute the value obtained into f(x) , that is

g(- 4) = - 2(- 4)² = - 2 × 16 = - 32, then

f(- 32) = 2(- 32 - 1) = 2 × - 33 = - 66
