If the mean of 4, y, 8 and 10 is 7. Find Y?
6
10
7
9
Correct answer is A
\(\frac{4 + y + 8 + 10}{4}\) = 7
22 + y = 4 x 7
22 + y = 28
y = 28 - 22 = 6
Integrate \(\frac{2x^3 + 2x}{x}\) with respect to x
\(\frac{2x^3}{3}\) - 2x + k
x3 + 2x + k
\(\frac{2x^3}{3}\) + 2x + k
x3 - 2x + k
Correct answer is C
\(\int\) \(\frac{2x^3 + 2x}{x}\) = \(\int\) \(\frac{2x^3}{x}\) + \(\frac{2x}{x}\) = \(\int\) (2x2 + 2) dx
\(\frac{2x^2+1}{2 + 1}\) + 2x + k
= \(\frac{2x^3}{3}\)+ 2x + k
