An auditorium has 15 rows of seats. Each row except the first has the same number of seats. The first row has 12 seats. On one occasion, 230 people were seated in the auditorium, and there were still empty seats. On another occasion, 240 people came to the auditorium, but there were not enough seats for all of them. How many seats are in the auditorium?

hreryryrranswer:

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2
