Given the position function s(t), s(t) = t3 - 5t, where s is measured in meters and t is in seconds, find the velocity and accel

Fantom [35]

Answer:

Step-by-step explanation:

given s(t) = t³ - 5t then

v(t) = s'(t) = 3t² - 5 and

v(3) = 3(3)² - 5 = 22 m / s, and

a(t) = v'(t) = 6t, then

a(3) = 6 × 3 = 18 m / s²

Solve the problem.

Answer:

The population reaches 42,336 fish in 2258

Step-by-step explanation:

Given:

$P = 0.62x^2 - 0.043x + 3$

To Find:

Time taken to reach 42,336 = ?

Solution:

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
