Answer:

The first graph

Step-by-step explanation:

Personally, I use the acronym HAY and VAX to remember this rule. This means that horizontal lines always correlate with y and vertical lines always correlate with x. A horizontal equation (y=#) is valid, so to say, whereas vertical (x=#) is undefined. It is undefined because there are multiple values of y for the same value of x. You can remember this with the following scenario: A person will always be able to walk in a straight line without getting injuries, but if a person tries to walk up the wall, they will fall and can break their bones, making their body "undefined"

1.) A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone? A.) 2cm
OLEGan [10]
Part A)
we know that 
[volume sphere]=(4/3)*pi*r³------> (4/3)*pi*3³--------> 113.04 cm³
[volume cone]=113.04=pi*r²*h/3------> h=[V*3]/[pi*r²]
r=6 cm
h=[V*3]/[pi*r²]---------> [113.04*3]/[pi*6²]---------> 3
h=3 cm

the answer part A) is h=3 cm

Part B)
[volume cylinder]=pi*r² *h---------> pi*1²*21------> 65.94 cm³
[volume cone]=65.94 cm³=pi*r²*h/3
h=7 cm
r=√[(V*3)/(pi*h)]---------> √[(65.94*3)/(pi*7)]---------> 3 cm

the answer Part B) is r=3 cm

Which statement describes the behavior of the function f (x) = StartFraction 3 x Over 4 minus x EndFraction?
katovenus [111]

f(x)=\frac{3x}{4-x}

First Method: Using Graph

Finding the limits as x approaches infinity and negative infinity is one way to solve this problem. As x reaches infinity, simply follow the graph line (colored purple) to the far right to find its limit. If we trace it, we can see that the Y value never exceeds -3 (orange), indicating that the limit is equal to -3 as x approaches infinity. You'd do the same with negative infinity, the limit is -3. We may now say the following:

\lim_{x \to \infty} (\frac{3x}{4-x})=-3 \\ \lim_{x \to -\infty} (\frac{3x}{4-x})=-3

And that's the answer to your question.

Second Method: Using Mathematics

I'm not sure if this solution is suitable for your stage, but you can solve this problem using L'Hopital's rule:

\lim_{x \to \infty} (\frac{3x}{4-x}) =\frac{\infty}{-\infty}\\=^L   \lim_{x \to \infty} (\frac{3}{-1}) = -3\\\\ \lim_{x \to- \infty} (\frac{3x}{4-x}) =\frac{-\infty}{\infty}\\=^L   \lim_{x \to- \infty} (\frac{-3}{1}) = -3

Two quantities, x and y, are directly proportional. If x is doubled, what happens to y?
vagabundo [1.1K]

Answer:

y is also doubled.

Step-by-step explanation:

Direct proportionality between x and y means that

y \propto x

or

y=cx,

which indicates a linear relationship between  x and y because they are related by a constant.

Therefore, if x is doubled, then the new value of y is y_{new}

y_{new}=c(2x)

y_{new}=2(cx)

y_{new}=2y

The new value of y is 2 times the previous; therefore, y is doubled as x is doubled.
