Answer:
m∠CDE = 60°
Step-by-step explanation:
Given that the arc at the center = 2 times the arc at the circumference, we have;
Angle at the center = arc CE = 120°
Whereby the angle at the circumference is given as m∠CDE and it is opposite the circle arc CE
We note that m∠CDE is the acute angle between chord DC and DE
Therefore, we have;
Angle at the center = 120° = 2 times the arc at the circumference = 2 × m∠CDE
120° = 2 × m∠CDE
m∠CDE = 120/2 = 60°
Therefore the angle of m∠CDE is equal to 60°.
It is decreasing at B. (ln9/3,∞)

Answer: No from what i did I got (2,0) for x and got (0,10) for y
Step-by-step explanation:
we can proceed to model the cost of Billy's Boat Rental Company
let y be the cost
let x be the number of rentals
y=105+9.5x----1
Also, the cost of Billy's Boat Rental Company
y=14.75------2
the question is <em> "How many times does a person have to rent a boat for the cost to be the same amount at both rental companies"</em>
we have to equate the two cost and solve for x
105+9.5x=14.75
105-14.75+9.5x=0
90.25+9.5x=0
9.5x=-90.25
divide both sides by 9.5 we have
x=-90.25/9.5
x=9.5
Approximately 10 times
