It is not appropriate because it isn't reflective of the points on the right side and its deviation from the points, which has an obvious positive correlation, is too great to be a line of best fit. To make it better, make it less steep and start the line close to the origin.

Answer:

Plot the following points on the graph

$(-1, \frac{1}{2})$ , (0, 1), (1, 2), (2, 4), (3, 8)

Step-by-step explanation:

If the equation for the line is y = $2^{x}$ , whatever the power/exponent "x" equals, then y is equal to however many times 2 is multiplied by x.

For example, if our domain is {-1, 0, 1 , 2, 3}

then we would plug in each x value into the exponent to find the y-value in order to plot the points to solve the problem.

If x = -1, then y = 1/2. **If there is an a negative exponent it would get turned into a positive fraction with the denominator as the positive version of that number.

$y = 2^{-1} = \frac{1}{2^{1} } = \frac{1}{2}$

If x = 0, then y = 1

**When the exponent is 0, the number automatically equals 1.

If x = 1, then y = 2.

If x = 2, then y = 4

If x = 3, then y = 8

So you would plot the following coordinates on the graph:

$(-1, \frac{1}{2})$

(0, 1)

(1, 2)

(2, 4)

(3, 8)

Calculate the volume of the cylinder, where a = 18 and b = 11. Use 3.14 for pi and round your answer to the nearest tenth.

cupoosta [38]

Answer:

Volume of cylinder $=2797.7$

Step-by-step explanation:

Let $a$ be diameter and $b$ the height of the cylinder

$Then\ radius(r)=\frac{diamater\ (a)}{2}\\\\r=\frac{18}{2}\\\\r=9$

Volume of cylinder $=\pi\times(radius)^2\times(height)$

$=\pi\times(9)^2\times11\ \ \ \ \ \ (\pi=3.14)\\\\=3.14\times9\times9\times11\\\\=2797.74\\\\\approx2797.7$

Mrs. Jones bought three 2-kilogram packages of flour. How many grams of flour did she buy?

Makovka662 [10]

It is given that, Mrs. Jones bought three 2-kilogram packages of flour.

And

$1 kilogram = 1000 grams$

And three 2 -kilogram packages means she bought 6 kilogram flour .

So we need to convert 6 kilogram flour into grams.

If,

$1 kilogram = 1000grams, \\ than, \\ 6 kilograms = 6*1000=6000 grams$

So she bought 6000 grams of flour .

Find the inverse of the function y = x^2 + 12x

PilotLPTM [1.2K]

Answer:

y=x\\

x=y^{2} + 12y\\

y^{2} + 12y -x = 0\\

Delta = (12^{2}) - 4.1.(-x) = 144 +4X = 36.(4+x)

\sqrt{Delta} = 6 . \sqrt{(4+x)} \\

y' = \frac{-12 + 6.(\sqrt{(4+x)}}{2} = -6 + 3.\sqrt{(4+x)}\\

y" = -6 - 3.\sqrt{(4+x)}\\\\

y' = 3.\sqrt{(4+x)} - 6\\

y''= -3.\sqrt{(4+x)} - 6\\

Answer:

The answer to your question is: y = 8x

Step-by-step explanation:

As both lines are parallels, then the slope is the same.

From the line given, get the slope

m = 8

Point (0, 0)

(y - y1) = m(x - x1)

(y - 0) = 8(x - 0)

y = 8x
