Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3
Answer: Dist = 8.94, midpoint = (1,6)
Step-by-step explanation:
Basically, the Distance between the points is the hypotenuse of a right triangle, whose legs are parallel to the x and y axes.
Leg 1 = x2 - x1 = 5 - -3 = 8
Leg 2 = y2 - y1 = 8-4 = 4
Hypotenuse = (8^2 + 4 ^2) ^ .5 = (64+16)^.5
Sqrt(80) = 8.94
The midpoint is aligned with the midpoint of each leg
X = 5 - 8/2 = 1
Y = 8 - 4/2 = 6
So (1,6) is the midpoint
Answer:
Quick Market
Step-by-step explanation:
You need to set up the problem in fraction form or 3/1.05 and 5/1.15
Then you need for the numbers to have the same denominator.
After doing that the fraction would look like 114/39.9 for Quick Market and 173.48/39.9 for Stop and Save.
So Quick Market costs less.

Answer:
Area = 40 cm²
Step-by-step explanation:
Area of triangle is derived by the formula,
Area = 
Length of Base = 8 cm
Height of the triangle = 10 cm
Therefore, area of the given triangle = 
= 40 cm²
