<em>Answer:</em>

<em>4289 kilometers squared</em>

<em>Step-by-step explanation:</em>

<em>This is an example of compounding. We start with the basic 4800 kilometers of land. We then find seven percent of the 4800 kilometers and subtract that same seven percent. If we are trying to find the area after twelve years, we must repeat this process twelve times. This does </em><u><em>not</em></u><em> mean that we find seven percent of 4800 then repeat subtracting the same amount. We need to fix the seven percent so that we can get seven percent of the amount we currently have.</em>

<em>With this in mind, we need to write a equation:</em>

<em />cv = cv/107<em>*</em>

<em>*Note that we are trying to find 93% of the current value (cv). We need to divide by 107%, not 7% (would be an illogical divisor). Then, when we divide by 107%, we have the 7% that we need to subtract by. There, we find the needed 93%</em>

<em>Now we can solve.</em>

<em>4800/107 = 45**(1)</em>

<em>4800 - 45 = 4755</em>

<em>4755***/107 = 44**(2)</em>

<em>***As mentioned earlier, we do not continue to subtract 45. We need to adjust to a new current value (cv).</em>

<em>4755 - 44 = 4711</em>

<em>4711/107 = 44**(3)</em>

<em>4711 - 44 = 4667</em>

<em>4667/107 = 44**(4)</em>

<em>4667 - 44 = 4623</em>

<em>4623/107 = 43**(5)</em>

<em>4623 - 43 = 4580</em>

<em>4580/107 = 43**(6)</em>

<em>4580 - 43 = 4537</em>

<em>4537/107 = 42**(7)</em>

<em>4537 - 42 = 4495</em>

<em>4495/107 = 42**(8)</em>

<em>4495 - 42 = 4453</em>

<em>4453/107 = 42**(9)</em>

<em>4453 - 42 = 4411</em>

<em>4411/107 = 41**(10)</em>

<em>4411 - 41 = 4370</em>

<em>4370/107 = 41**(11)</em>

<em>4370 - 41 = 4329</em>

<em>4329/107 = 40**(12)****</em>

<em>****Meaning that this is the last year</em>

<em>4329 - 40 = 4289</em>

<em>Your answer is 4289 kilometers squared.</em>

<em>Hope this helped.</em>

The function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)

<h3>How to write a function of the length z in meters of the side parallel to the wall?</h3>

The given parameters are:

Perimeter = 210 meters

Let the length parallel to the wall be represented as z and the width be x

So, the perimeter of the fence is

P = 2x + z

This gives

210 = 2x + z

Make x the subject

x = 1/2(210 - z)

The area of the wall is calculated as

A = xz

So, we have

A = 1/2(210 - z) * z

This gives

A = z/2(210 - z)

Rewrite as

A(z) = z/2(210 - z)

Hence, the function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)

In a right angle,the altitude to a 6ft hypotenuse.Find the length of the altitude and each leg.
Nuetrik [128]

Answer:a=3.6 and b=4.8

Step-by-step explanation:(a^2)+(b^2)=(c^2)

Where c is hypotenuse is equal to 6. A right triangle is also known as a 3,4,5 triangle where the 2 legs are 3 and 4 and hypotenuse is 5. Find the factor in size difference by dividing your hypotenuse of 6 by the hypotenuse of 5 you get 1.2. Now multiply the 3 and 4 by 1 2 to get your answers of 3.6 and 4.8.

To check work simply plug in your legs as a and b

(3.6^2)+(4.8^2)=(6^2)

(12.96)+(23.04)=(36)
