Answer:

P(t) = 27000 * (1/9)^(t/4)

Step-by-step explanation:

This problem can me modelled with an exponencial formula:

P = Po * (1+r)^t

Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.

In this problem, we have that the inicial population/value is 27000, the rate is -8/9 (negative because the population decays), and the time t is in months, so as the rate is for every 4 months, we use the value (t/4) in the exponencial.

So, our function will be:

P(t) = 27000 * (1-8/9)^(t/4)

P(t) = 27000 * (1/9)^(t/4)

Someone please solve with work. Much appreciated!! A rectangular sheet of metal is 250 cm wide and has a diagonal of 472cm. Find

Lorico [155]

The length of rectangular sheet is 400.35 cm

The area of rectangular sheet is 100087.5 square centimeters

Solution:

Given that,

Width of rectangular sheet = 250 cm

Diagonal of rectangular sheet = 472 cm

To find: length and area of rectangular sheet

The figure is attached below

Consider the rectangle ABCD

CD is the length = ?

BC is the width = 250 cm

BD is the diagonal = 472 cm

The diagonal BD and length and width forms a right angled triangle with diagonal as hypotenuse

We can use Pythogoras theorem to find length

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

By above definition for right angled triangle DCB,

$BD^2=BC^2 + CD^2$

$472^2 = 250^2 + CD^2\\\\222784 = 62500 + CD^2\\\\CD^2 = 222784 - 62500\\\\CD^2 = 160284\\\\\text{Take square root on both sides }\\\\CD = \sqrt{160284}\\\\CD = 400.35$
