Facts:
Bottles sold daily: 140 million
Each bottle: ~0.25 meters
Equator : 40 million meters

140 mil. Bottles * 0,25 m = 35 million meters

35<40 ( equator) which means you can't circle it not even once with the bottles sold in US in one day!

So 40:35= 0,875

That means we can circle only 87.5% of the Equator!

Info: you need 160 million bottles to circle the Equator once.

The sides of a polygon are 3, 5, 4, and 6. The shortest side of a similar polygon is 9. Find the ratio of their perimeters.
Rainbow [258]
The given polygon has a perimeter of 3 + 5 + 4 + 6 = 18
A similar polygon has sides that are 3 times as big ot 9 + 15 + 12 + 18 = 54

The ratio is 18/54 or 1/3

A phone company uses the equation y = 0.15x + 10 to find y, the monthly charge for a customer sending x text
olasank [31]

Hey!

---------------------------------------

Solution:

77.50 = 0.15x + 10

77.50 - 10 + 0.15x + 10 - 10

67.50 = 0.15x

0.15x = 67.50

0.15x/0.15 = 67.50/0.015

x = 450

---------------------------------------

Check:

77.50 = 0.15(450) + 10

77.50 = 67.50 + 10

77.50 = 77.50

---------------------------------------

Answer:

450 text messages can be sent when the monthly charge is $77.50!

---------------------------------------

Find the intercepts and asymptotes, use limits to describe the behavior at the vertical asymptotes. (37 and 39)
n200080 [17]
39)
Its always best to factorise where you can, in most questions it tends to be a necessary step and even if its not, it usually makes things easier;
In this case, you can factorise the denominator:
h(x) = \frac{x \ - \ 1}{ x^{2} \ - \ x \ - \ 12} \\\\ = \frac{x \ - \ 1}{(x \ - \ 4)(x \ + \ 3)}

To get y-intercept/s, set x = 0 and solve:
h(0) = \frac{(0) \ - \ 1}{((0) \ - \ 4)((0) \ + \ 3)} \\\\ =  \frac{-1}{-12} \\\\ =  \frac{1}{12}
y-intercept: (0, 1/12)

To get x-intercept/s, set y = 0 and solve:
\frac{x \ - \ 1}{(x \ - \ 4)(x \ + \ 3)} = 0 \\\\ x \ - \ 1 = 0 \\\\ x = 1
x-intercept: (1, 0)

To find the asymptotes, it is necessary for us to have factorised the denominator so its a good thing that I did so at the beginning;

To get the vertical asymptote/s, set the denominator equal to 0, then just rearrange to get x:
(x \ - \ 4)(x \ + \ 3) = 0 \\ x \ - \ 4 = 0 \\ x = 4 \\ and \\ x \ + \ 3 = 0 \\ x = -3
vertical asymptotes: x = 4  and  x = -3

There are no horizontal asymptotes.
