Answering your question on "9 students can make a poster in 10 hours. How many students should join them so that they all together can make this poster in 6 hours" its 13 students
30x² - 5 monomial
pls follow me ; )
Answer:
B
Step-by-step explanation:
The area between the curves y = d and y = f(x), between the limits x=a and x=b, is:
∫ₐᵇ (d − f(x)) dx
Alternatively, the area between the curves x = f(y) and x = a, between the limits y = c and y = d, is:
∫ᵈ (f(y) − a) dy
Answer A would give you the area between x = f(y) and the y-axis. It needs to include the − a term to be correct.
The sequence is changing the number -8 is multiplied by by 1 less than the previous number.
The next sequence would be -8 x -1 = 8
The answer would be D.
