Since the height is different on both ends, we can assume that the wall is a trapezoid. Knowing that, we can replace the measures we know in the formula and our onky variable is the length of the wall - we only need to isolate it. A= ((b+B)h)/2 26.4=((2+2.4)h)/2 52.8=4.4h h=12

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

Answer:

12.5%

Step-by-step explanation:

percent change is calculated as

$\frac{change}{original\\}$ x 100

change = 32 − 28 = 4 pages

$\frac{4}{32}$ x 100% = $\frac{100}{8}$ % = 12.5 %
