Answer:

Step-by-step explanation:

Given that the fish population in a certain part of the ocean (in thousands of fish) as a function of the water's temperature (in degrees celsius) is modeled by: p(x)=-2(x-9)^2+200.

To find maximum number of fish, we use derivative test

p(x)=-2(x-9)^2+200\\p'(x) =4(x-9)\\p"(x)=4>0

Since second derivative is positive,

there will not be any maximum but only minimum

2(x-9) =0x=9

Minimum when x=9 and minimum population

p(x) =200

Maximum when x -infinity

Alex

The decrease is 8.7%

Step-by-step explanation:

Old price = $23000

New price = $21000

Difference = New price - Old price

Difference = 21000 - 23000 = -2000

The negative sign indicates the decrease.

Percent\ decrease=\frac{Difference}{New\ value}*100\\\\Percent\ decrease=\frac{2000}{23000}*100\\\\Percent\ decrease=\frac{200000}{23000}\\\\Percent\ decrease=8.69\%

Rounding off to nearest tenth;

Percent decrease = 8.7%

The decrease is 8.7%

Keywords: difference, percentage
