Answer:
229.2
Step-by-step explanation:
Remark
There's a lot in this question. The x is not just any x. It is defined and limited by its relationship with the sine function.
The Sin is defined as Opposite over Hypotenuse in a right triangle. The 670 is the Hypotenuse. You know that by the definition of Sine.
So one thing you should always keep in mind: the x because of where it is in the definition, will always be smaller than the Hypotenuse. So you should get a value less than 670.
Formula
Just as you have it
Sin(20) = x / 670
Solution
Multiply both sides by 570
670 * sin(20) = x
sin(20) = 0.3420
x = 670 * 0.3420
x = 229.2
Imagine he second side is x so the first side is (x-3) and the third side is (x+4)
So x + (x-3) + (x+4) = 34
3x+1 = 34
3x=33
X=11
So longest side is (x+4) so 11+4=15

The question is not properly formated, here is the correct format
<em>The revenue function is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=274−4x, find the revenue if 12 units are sold. Round to two decimal places.</em>
<em />
Step one
given the following expression
Revenue
Unit price
Required
the revenue when 12 units were sold
let us find the unit price for 12 units
Hence the unit price is$ 226
Revenue is $2712
