Answer:
is an extraneous solution: True
is the only solution: True
Step-by-step explanation:
The given logarithmic equation is: 
Apply the property 
to the LHS to get: 
We rewrite the corresponding indicial expression to get:
Simplify the RHS to get:
Take square root to get:
Since the domain of the logarithmic function is positive real numbers, the only solution is
Perimeter is 29.165
Each line is equal to the square root of (x2-x1)^2 + (y2-y1)^2
The area of the portion of the windshield cleaned by the 10-in wiper blade is 106.85in² .
We have been provided that the Length of blade is 15 inches and the Angle of rotation = 98°
We are required to calculate the area of the portion of the windshield cleaned by the 10-in wiper blade.
We have to solve this by using area of a sector.
Area of a sector = ½r²θ
where θ is in radians.
So, angle of rotation (98°) must first be converted to radians
Converting 98º to radians, we get
98×π/180 = 49π/90
The area of the region swept out by the wiper blade
= (area of the sector where r = 15 and θ = 49π/90) - (area of the sector where r = (15-10) and θ = 49π/90).
So, Area = ½×15²×49π/0 - ½×5²×49π/90
= ½×49π/90(15²-10²)
= 49π/180× (225 - 100)
= 49π/180 × 125
= 1225π/36
Area = 106.8472in²
=106.85 in²
Hence, the area of the portion of the windshield cleaned by the 10-in wiper blade is 106.85in²
