Answer:
Answer: 64/3π -16/3)in²
Step-by-step explanation:
Area of segment equals area of sector minus area of isosceles triangle.
=0/360 x πr² -1/2r²sin (0)
Given; the length of chord, d=8√3in.
and the angle of the sector, 0=120
We can use the formula for calculating the length of a chord to find the radius of the circle.
D = 2r sin (0/2)
8√3= 2r (√3/2)
r=8in
Area of the segment= 120/360 x π x 8² - ½ x 8² sin (120)
= (64/3 π- 16 √3)in²
Answer:
- <u>$45</u> (with the assumption made below)
Step-by-step explanation:
The equation is garbled; thus, to explain you I will assume the equation is
Where:
- R(s) is the revenue in dollars, as a function of the number of seats occupied.
- s is the variable that represents the number of seast occupied
- 14 is the rate of change of the revenue per seat occupied (the price of a ticket).
- -325 is the fixed cost of the theater for a performance (the amount of money the theater will lose if none seat is occupied).
Thus, you can predict the revenue when 70 seats are occupied by substituting s with 70.
- R(70) = -325 + 980 = $655
The <em>residual value</em> from a prediction is equal to the real value (observed value) less the preducted value:
- Residual = real revenue - predicted revenue
- Residual = $700 - $655 = $45
