Answer:

d. 16

Step-by-step explanation:

AB and AD are tangents from external point A to the circle with center C.

Since, tangents drawn from external point to a circle are congruent.

\therefore \: AB = AD \\  \therefore \: 7x + 4 = 3x + 68 \\ \therefore \: 7x - 3x = 68 - 4 \\  \therefore \: 4x = 64 \\  \therefore \: x =  \frac{64}{4}  \\  \huge \red{ \boxed{\therefore \: x = 16}}

Find the partial derivatives of the function w=4r2+6s2+
lyudmila [28]

The partial of w with respect to r is 8r.  That with respect to s is 12s.</span>
