What is the equation of the line, written in slope-intercept form? Show how you determined the equation.

kondor19780726 [428]

The equation of a line is defined by: y=mx+b

Step 1: Find the slope (rise over run) so, the rise is 15.7 and the run is 6. 15.7/6=2.62

y=2.62x+b

Step 2: Find the b value (y intercept) - this is where the line goes through the y axis. In this case, it's 15.7

Step 3: add the slope and the b value together - y=2.62x+15.7

What is There are fourteen whole snack bars on a plate. There are five friends.

AleksandrR [38]

Carl is incorrect. Dave ate a higher fraction of snack bars, by 0.2 snack bars.

Carl had .5 left of a snack bar.

Dave had .3 left of a snack bar.

Tony had .5 left of a snack bar.

Gary had .0 left of a snack bar.

Tryone had .7 left of a snack bar.

If we add the above snack bars, there is a total of two remaining snack bars, meaning they only ate 12 of 14 snack bars.

Which of the following equations is an example of inverse variation between

Romashka [77]

For this case we have that by definition, a direct variation is given by:

$y = kx$

Where:

k: It is the constant of proportionality of the variables.

On the other hand, we have that the inverse variation is given by:

$y = \frac {k} {x}$

Where:

k: It is the constant of proportionality of the variables.

In this way, the correct option is: $y = \frac {9} {x}$

ANswer:

Option A

A standard piece of paper is 0.05 mm thick. Let's imagine taking a piece of paper and folding the paper in half multiple times.

tatyana61 [14]

Answer:

(a) $g(n)=0.05\cdot 2^n$

(b) $g^{-1}(n)=\log_{2}20g(n)$

Step-by-step explanation:

Part A

The paper's thickness = 0.05mm

When the paper is folded, its width doubles (increases by 100%).

The thickness of the paper grows exponentially and can be modeled by the function:

$g(n)=0.05(1+100\%)^n\\\\g(n)=0.05\cdot 2^n$

Part B

$g(n)=0.05\cdot 2^n\\2^n=\dfrac{g(n)}{0.05}\\ 2^n=20g(n)\\$Changing to logarithm form, we have:\\\log_{2}20g(n)=n\\$Therefore:\\g^{-1}(n)=\log_{2}20g(n)$

Part C

If the thickness of the paper, g(n)=384,472,300,000 mm

Then:

$g^{-1}(n)=\log_{2}20g(n)\\g^{-1}(n)=\log_{2}20\times 384,472,300,000\\=\dfrac{\log 20\times 384,472,300,000}{\log 2} \\g^{-1}(n)=42.8 \approx 43\\n=43$

You must fold the paper 43 times to make the folded paper have a thickness that is the same as the distance from the earth to the moon.
