Step-by-step explanation:

The triangle is a right triangle.

We can use trigonometric functions to solve.

$\sf sin(\theta)=\frac{opposite}{hypotenuse}$

$\sf sin(60)=\frac{5.2}{KL}$

$\sf KL=\frac{5.2}{sin(60)}$

$\sf sin(90-60)=\frac{3}{KL}$

$\sf KL=\frac{3}{sin(90-60)}$

I NEED HELP WITH ALL OF THESE PLEASE! I HAVE A TEST AND I NEED HELP ASAP

Studentka2010 [4]

So what you do for distributive property is take #1 for example: 3(2x + 10) = 54. When there’s a parenthesis, you take the outside number which is the 3 times the numbers inside the parenthesis. So after doing that first step you should get 6x + 30 = 54. Now you want to get rid of the 30 so you do 30-30=0 but you have to do it on the other side as well. So subtracting 30 on both sides you should have 6x = 24. Now you want to get x by itself. The opposite of multiplying is dividing so you divide 6 from 6x. So the same on the other side. You get your answer x=4 if you did everything correct

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the

sineoko [7]

Answer:

x = $34.45

Step-by-step explanation:

Solution:-

The company makes a profit of $y by selling widgets at a price of $x. The profit model is represented by a parabola ( quadratic ) equation as follows:

$y = -10x^2 + 689x -6775$

We are to determine the profit maximizing selling price ( x )

From the properties of a parabola equation of the form:

$y = ax^2 + bx + c$

The vertex ( turning point ) or maximum/minimum point is given as:

$x = -\frac{b}{2a} \\\\x = - \frac{689}{2*(-10)} = \frac{689}{20}\\\\x = 34.45$

The profit maximizing selling price of widgets would be x = $34.45.
