A certain forest covers an area of 2100 km^2. Suppose that each year this area decreases by 5.25%. What will the area be after 6

Neko [114]

Answer:

The area after 6 years is $1519.49km^2$

<em></em>

Step-by-step explanation:

Given

$a = 2100$ --- Initial Value

$r = 5.25\%$ --- Rate

Required

Determine the area after 6 years

Because the area reduces,, the following formula will be used to solve the question.

$y = a*(1 - r)^t$

Here

$t = 6$

So, we have:

$y = 2100*(1 - 5.25\%)^6$

Convert percentage to decimal

$y = 2100*(1 - 0.0525)^6$

$y = 2100*(0.9475)^6$

$y = 1519.47866516$

$y = 1519.49$ -- approximated

<em>The area after 6 years is </em> $1519.49km^2$ <em></em>

Find the distance of each segment AB and CD. You may leave in radical form. A (3, 4) B(1, 0) and C (-1, 2) D (-2, 5)

Whitepunk [10]

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

AB

$\sqrt{(1-3)^2+(0-4)^2}$

$\sqrt{4+16}$

$\sqrt{20}$

$2\sqrt5$

CD

$\sqrt{(-2-(-1))^2+(5-2)^2}$

$\sqrt{1+9$

$\sqrt{10}$

Hope this helps.

頑張って!
