t= 2.25 secs

Step-by-step explanation:

Step 1 :

Equation for motion with uniform acceleration is v = u+ at

where v is the final velocity

u is the initial velocity

a is the acceleration due to gravity

and t is the time

Step 2 :

Here , v = 0 because at the highest point final velocity is 0.

u = 72 feet/sec

a = -32 ft/sec^2

We need to find the time t.

Substituting in the equation we have,

0 = 72 -32 * t

=> 32 t = 72

=> t = 72/32 = 2.25 secs

There is a pond on my property that Wildlife and Fisheries stocks. From information provided to me, I can expect my fish populat

An exponential function can either represent growth or decay

The initial value is 200 and the growth factor is 1.190
The number of fish in the pond after 5 years is 436

<u>(a) The initial number of fish and the growth factor</u>

The function is given as:

$P(t) = 200 \times 2^{t/4}$

An exponential function is represented as:

$P(t) = ab^t$

Where

a represents the initial value
b represents the growth factor

So, by comparison: the initial value is 200

The growth factor is then calculated as:

$b = 2^{1/4}$

$b = 1.190$

Hence, the initial value is 200 and the growth factor is 1.190

<u>(b) The number of fish after 5 years</u>

This means that t = 5.

So, we have:

$P(t) = 200 \times 2^{t/4}$

$P(5) = 200 \times 2^{5/4}$

$P(5) = 200 \times 2^{1.125}$

$P(5) = 436$

Hence, the number of fish in the pond after 5 years is 436
