Since this is a 30-60-90 triangle, the sides are in this proportion-
Shortest side (opposite of 30 degree angle)-x (v)
Longest side (opposite of 90 degree angle)-2x
Medium Side (opposite of 60 degree angle)- x(square root of 3)
So 23 is in the 2x proportion. x is v so solve for v like this-
23=2v
Divide 2.
v=11.5
Since v is x and x(square root of 3) is u, solve-
11.5*square root of 3
So-
v=11.5
u=11.5(square root of 3)
Yes, you are correct. I just put it in decimal form. :)

The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).

<h3>What is the parabola?</h3>

It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.

The function f(x) = 5x² + 40x

Then add and subtract 80, then we have

f(x) = 5x² + 40x + 80 – 80

f(x) = 5(x² + 8x + 16) – 80

f(x) = 5(x + 4)² – 80

The vertex of the parabola will be at (–4, –80).

More about the parabola link is given below.

Karmin will make $18.4 for working an hour after the increase.

Step-by-step explanation:

Step 1:

First, we need to determine how much Karmin made an hour.

Karmin's hourly rate $= \frac{480}{30} = 16.$

So Karmen made $16 every hour that she worked. She worked for 30 hours and earned $480.

She will get a 15% increase in her hourly rate this month.

Step 2:

We need to determine how much 15% of $16 is.

15% of $16 $= \frac{15}{100} (16) = 0.15 (16)= 2.4.$

So her 15% increase amounts to $2.4.

So the hourly rate for this month $16 + 2.4 = 18.4.$

So Karmin will make $18.4 for working 1 hour.
