let's firstly, convert the mixed fraction to improper fraction, and then subtract.
Answer:
38.9 square inches.
Step-by-step explanation:
We are asked to find the difference in area covered by a single 3 inch windshield wiper operating with a central angle of 138 degrees compared to a pair of 5 inch wipers operating together each having a central angle of 114 degrees.
We will use area of sector formula to solve our given problem as:
, where, r represents radius and theta represents central angle.
Let us find area of sector with central angle 140 degree and radius 3 inch.
Now, we will find area of sector with central angle 114 degree and radius 5 inch and multiply by 2 as:
Let us find difference of area as shown below:
Therefore, the difference in area covered is approximately 38.9 square inches.
The given expression is
THe given expression is a rational expression, and rational expression should not have 0 in the denominator.
Moreover, the denominator is a square root term, and square root don't have a value for negative number .
Therefore 2x+10 must be greater then 0. That is
Therefore the required domain in set builder form is
