Correct Answer: D. ( \(\frac{-1}{2}\), \(\frac{15}{2}\) )

Explanation

Given Data: x\(_1\) = -3, x\(_2\) = 2, y\(_1\) = 5, y\(_2\) = 10

coordinates of the mid-point of the line = (\(\frac{x_1 + x_2}{2}\) , \(\frac{y_1 + y_2}{2}\))

(\(\frac{-3 +2}{2}\) , \(\frac{5 + 10}{2}\))

= \(\frac{-1}{2}\)) , \(\frac{15}{2}\))

Correct Answer: A. Constituency

Correct Answer: A. 9

Explanation

\(\int^3_0(px^2 + 16)\) = 129

\(\frac{px^2 + 1}{0 + 1} + 16x|^3_0 = 129\)

\(\frac{px^3}{3} + 16x|^3_0 = 129\)

(\(\frac{p(3)^3}{3} + 16(3)\)) - 0 = 129

9p + 48 = 129

9p = 129 - 48

\(\frac{9p}{9} = \frac{81}{9}\)

p = 9
