To solve this, you need to subtract 28 from both sides, then solve.
y=x^2+3x-28
The x-intercepts are (-7,0) and (4,0)
Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
Answer:
12
Step-by-step explanation:
The rate the jukebox is playing the same song is 8 per 50 songs or in other words 4 per 25 songs. Since we are looking for 75 just multiply 25 and 4 by 3 and you get 12 repeated songs per 75 songs
Answer:
Y-intercept: 59
Step-by-step explanation:
Y=mx+b, in which b stands for y intercept
