What is greater 0.7 or 3/5
steposvetlana [31]
The answer would be 0.7 since we can say that 3/5 of 100 makes 60 while 0.7 is 70 which means that 0.7 has more.

The curve y = |x|/ 5 − x2 is called a bullet-nose curve. find an equation of the tangent line to this curve at the point (2, 2).
diamong [38]
We have the following curve:

y=\frac{\left | x \right |}{5-x^2}

So we need to find <span>an equation of the tangent line to this curve at the point (2,2). So let's find out if this point, in fact, belongs to the curve:

</span>If \ x=2 \\ \\ y=\frac{\left | 2 \right |}{5-2^2}=\frac{\left | 2 \right |}{5-4}=2. 
<span>
We also know that:

</span>\left | x \right |= \left \{ {{x \ if \ x \ \geq 0} \atop {-x \ if \ x\ \textless \ 0}} \right.<span>

Given that the point is:

</span>(2,2)\ that \ is: \\ x=2\ \textgreater \ 0

Then we will say that:

\left | x \right |=x

Therefore:

y=\frac{x}{5-x^2}

Computing the derivative:

y=\frac{x}{5-x^2} \\  \frac{dy}{dx}= \frac{(1)(5-x^2)-(-2x)x}{(5-x^2)^2}=\frac{5+x^2}{(5-x^2)^2}

So the derivative solved for x=2 is in fact the slope of the line at the point (2,2), then:

\frac{dy}{dx} |_{x=2}=\frac{5+x^2}{(5-x^2)^2}|_{x=2}=\frac{5+2^2}{(5-2^2)^2}=9 \\ \\ \therefore m=\frac{dy}{dx} |_{x=2}=9

Finally, the tangent line is:

y-y_1=m(x-x_1) \\ \therefore y-2=9(x-2) \\ \therefore \boxed{y=9x-16}

<em>This is shown in the figure below.</em><span>

If 2s +10r = 2(2s-5r) = 42, then what is the value of r?
Lesechka [4]
R=7/5
You can list two equations:
2s+10r=42 and 4s-10r=42.
Then try to delete S, you will get r
