1.<br> Y = C/X<br> Solve for x<br><br> 2.<br> C/5 = (F-32)/9 <br> If C=25, solve for F

Arlecino [84]

Answer:

Step-by-step explanation:

y = c/x

multiply both sides of the equation by x:

xy = c

divide both sides by y:

x = c/y

::::::

25/5 = (f-32)/9

5 = (f-32)/9

45 = f-32

45+32 = f

f = 77

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>

Let f(x)=3x-7 and g(x)=2x². Perform the function operation and then find the domain of the result.

olya-2409 [2.1K]

Answer: A

Step-by-step explanation:

$f(x)=3x-7\\g(x)=2x^2$

$(f-g)(x)=3x-7-(2x^2)\\(f-g)(x)=3x-7-2x^2\\(f-g)(x)=-2x^2+3x-7$
