100x12= (10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10X12)= 700
Answer:
The percent error in the speeds are 7.1428 %.
Step-by-step explanation:
The percent error of any value is found by,
![error percent = (\frac{|(reading value)-(correct value)|}{correct value})(100)](https://tex.z-dn.net/?f=error%20percent%20%3D%20%28%5Cfrac%7B%7C%28reading%20value%29-%28correct%20value%29%7C%7D%7Bcorrect%20value%7D%29%28100%29)
<em>Here, the reading value is 60 mph and the correct value is 56 mph.</em>
Hence inserting this value in above equation, we get
![error percent = 7.1428 %](https://tex.z-dn.net/?f=error%20percent%20%3D%207.1428%20%25)
<em>Hence, the percent error in the speeds are, 7.1428 %.</em>
Answer: y<2
Step-by-step explanation:
Since we can say a functions could be added to the system without changing the solution set if after including it to the system the feasible region of entire system is not affected.
Here, the solution to the system of inequalities is,
y≤ 0.5x+2
y>3x-3
Since after ploting these two enequslties in the graph we get our feasible region.
When we include y > 2 in the system there is no solution of the system.
Therefore it affects the system.
Now when we include y < 2 in the system the solution or feasible region remain same.
Therefore it does not affect the system.
When we include y > 3 in the system there is no solution of the system.
Therefore it affects the system.
When we include line y=3 in the system then the system has no solution.
Therefore, it affects the system.
Thus, second Option is correct.
Answer:
70

Answer:
The answer is
<h2>1225</h2>
Step-by-step explanation:
4x² + 5 - 6x³ + 3x⁴ - x
x = - 4
Substitute the value of x into the expression
That's
4(-4)² + 5 - 6(-4)³ + 3( 4 )⁴ - - 4
Simplify
4(16) + 5 - 6( -64) + 3( 256) + 4
64 + 5 + 384 + 768 + 4
We have the final answer as
<h3>1225</h3>
Hope this helps you
