The first three surveys have similar results but the last one is significantly different from the others.
It indicates twice as greater number towards English and almost twice as smaller numbers against the Math and Science.
This is likely biased survey.
Step-by-step explanation:
x³ - 4x² - 25x + 100k
= x²(x - 4) - 25(x - 4k)
= (x² - 25)(x - 4k)
= (x + 5)(x - 5)(x - 4k)
Hence the other 2 zeroes are x = -5 or x = 5.
Answer:
sec(60) = 2
Step-by-step explanation:
sec(theta) = 1/cos(theta)
theta = 60o
cos(60) = 1/2 = 0.5
sec(theta) = 1/0.5 = 2
south America = 2.2%
2.2% = 0.022
0.022 = 22/1000 which reduces to 11/500
