Find the derivative of f(x)= -12x^2+9x
dexar [7]

Answer:

- 24x + 9

Step-by-step explanation:

Differentiate each term using the power rule

\frac{d}{dx} ( ax^{n} ) = nax^{n-1}

Given

f(x) = - 12x² + 9x, then

f'(x) = (2 × - 12)x + (9 × 1) x^{0}= - 24x + 9

The figure below shows a trapezoid, ABCD, having side AB parallel to side DC. The diagonals AC and BD intersect at point O.
Harlamova29_29 [7]

Answer:

<em>Length of BO is </em><em>three times the length of DO.</em>

Step-by-step explanation:

In trapezoid ABCD, CD\ ||\ AB

In ΔCDO and ΔABO,

  1. m\angle CDO=m\angle ABO (Alternate interior angles)
  2. m\angle DCO=m\angle BAO (Alternate interior angles)

So, \Delta CDO\sim \Delta ABO according to Angle-Angle similarity.

Therefore, the ratio of corresponding sides will be same.

\Rightarrow \dfrac{OD}{OB}=\dfrac{OC}{OA}

\Rightarrow \dfrac{OD}{OB}=\dfrac{OC}{3\cdot OC}

\Rightarrow \dfrac{OD}{OB}=\dfrac{1}{3}

\Rightarrow OB=3\cdot OD
