Answer:
The absolute error = 2 centimeters.
The desirable length = 45 cm
The minimum length = 43 cm.
The maximum length = 47 cm.
Step-by-step explanation:
Katie has been given a project to make a model car that is 45 centimeters long. The teacher has told her that variations in the length of up to 2 centimeters are acceptable.
Therefore, the absolute error = 2 centimeters.
The desirable length = 45 cm
The minimum length = (45 - 2) = 43 cm.
The maximum length = (45 + 2) = 47 cm. (Answer)
no substituion only rea numbersStep-by-stion:
we know that
Angles in a linear pair are supplementary angles
So
Let
A-------> the first angle
B------> the second angle
----> equation 

Substitute the values of A and B in the equation 


therefore
the answer is
the value of x is 
Second option: down on the left, down on the right.
Clearly when x is bigger than one the term -x^38 will dominate the result.
When absolute value of x grows, x^38 becomes a larger positive number and - x^38 a larger negative number. Then both ends of the function tend to negative infinity.
