Answer:
The point of diminishing returns (x , y ) is (11, 21462)
Step-by-step explanation:
From the question we are told that
The function is 
Here R(x) represents revenue (in thousands of dollars) and x represents the amount spent on advertising (in thousands of dollars).
Now differentiating R(x) we have

Finding the second derivative of R(x)

at inflection point 
So 
=> 
substituting value of x into R(x)


Now the point of diminishing returns (x , y ) i.e (x , R(x) ) is
(11, 21462)
Answer:
0
Step-by-step explanation:
Since displacement is the distance between the journey starting point and the final point if they both are the same the difference becomes zero and hence the displacement.
Displacement = final point - initial point
(<em>both</em><em> </em><em>are</em><em> </em><em>same</em><em>)</em>
<em>=</em><em> </em>same - same
= 0
Step-by-step explanation:
x+30°=180°{ straight angle}
x=180-30
x=150°

Yes it is possible if it doesn't have parentheses
Answer:
RST= 105 degrees
Step-by-step explanation:
it would be 2(5x+15) + 2(4x+3) =360
10x+30+8x+6=360
18x=324
x=18
so RST=5x+15=5(18)+15=105
