Answer:

The answer is: the domain of the function that show the population-growing per day is

\mleft{

$x \geqslant 0$

\mright}

Because the domain is the time, in this cases the days.

A can of tuna has a volume 18pi cm3 and a height of 2 cm. Find the area of the label that wraps around the entire can and does n

Sphinxa [80]

Answer:

The area of the label is $12\pi\ cm^{2}$

Step-by-step explanation:

step 1

Find the radius

we know that

The volume of the cylinder (can of tuna) is equal to

$V=\pi r^{2} h$

In this problem we have

$V=18\pi\ cm^{3}$

$h=2\ cm$

substitute and solve for r

$18\pi=\pi r^{2} (2)$

Simplify

$18=r^{2}(2)$

$r^{2}=9$

$r=3\ cm$

step 2

<em>Find the lateral area of the can</em>

The lateral area of the cylinder (can of tuna) is equal to

$LA=2\pi rh$

we have

$r=3\ cm$

$h=2\ cm$

$LA=2\pi (3)(2)=12\pi\ cm^{2}$

So it started at 180. After 4 more years it’s grown 188 cm to 368. If we estimate that it’ll grow 188 cm in another 4 years that puts our total to around 556. If we estimate and take off a year, it would probably be around 548 cm :)

5. The cost of a notebook increased from $4.30 to $4.58, what is the percent increase?

KonstantinChe [14]

The answer is 6.5
Explanation : 1. Find out the increase number by subtracting 4.58 - 4.30 = 0.28 or 6.51%
2. Divide the increase number 0.28 by 4.30 and multiple by 100 which gives you 6.51162791 .
3. Get rid of all the numbers behind 5 and you can’t round it because 1 is too small. Which then gives you the answer 6.5 :) <3
