Here is a way my class does this. We basically copy the graph and points on some tracing paper (you can find this in the art shop if you have time) and rotate the tracing paper 90* counter or 90* clockwise and there is your answer :)

Using the technique in the model above, find the missing sides in this 30°-60°-90° right triangle. Hypotenuse = 12 Long =

aleksandrvk [35]

When using the 30° - 60° - 90° method, the side lengths will always be x and x√3 for the legs and 2x for the hypotenuse.

Because the hypotenuse is 12, the equation is:
2x = 12

And now you find x to get the length of the shortest leg.
2x = 12
x = 6

Now that we know the length of x, you just add √3 in order to find the longest leg.

Therefore, the length of the longest leg would be 6√3.

If u(x) = x^5 - x^4 + x^2 and v (x) = -x^2 which expression is equivalent to ( u/ v) (x)

yawa3891 [41]

Answer:

$(u/v)(x)=-x^{3}+x^{2}-1$

Step-by-step explanation:

You have the following functions:

$u(x)=x^{5}-x^{4}+x^{2}\\v(x)=-x^{2}$

Therefore $(u/v)(x)$ indicates that you must divide both functions, as you can see below:

$(u/v)(x)=\frac{x^{5}-x^{4}+x^{2}}{-x^{2}}$

Simplify it. Therefore, you obtain:

$(u/v)(x)=\frac{x^{5}-x^{4}+x^{2}}{-x^{2}}\\\\(u/v)(x)=-x^{3}+x^{2}-1$
