The drag force \( F \) on a boat varies jointly with the wet surface area \( A \) of the boat and the square of the speed \( s \) of the boat. A boat v \( 42 \mathrm{ft}^{2} \) traveling at 10 mph experiences a drag force of 210 N . Find the speed of a boat experiencing a drag force of 405 N and havii \( 36 \mathrm{ft}^{2} \).

Add. State the sum in simplest form. \( \frac{a^{2}-6}{15 a^{3} b^{2}}+\frac{3}{10 a b^{2}} \) \( 0 \frac{a^{2}-3}{150 a^{4} b^{4}} \) \( \frac{a^{2}-3}{15 a^{3} b^{2}+10 a b^{2}} \) \( 0 \frac{a^{2}-3}{30 a^{3} b^{2}} \) \( \frac{11 a^{2}-12}{30 a^{3} b^{2}} \)

b. read none of magazine at all c. read exactly one of the magazines. 3. Use Mathematical induction to prove that \( x^{n}+y^{n} \) is divisible by \( x+y \) for odd natural number \( n \geq 1 \). 4. Solve the equation \( z^{6}+1=\sqrt{3} i \) where \( z \in c \).

\( x=3f(x)=\frac{1}{2}x^{2}-\frac{1}{2} \)

2. Find the value of \( x \) if \( 9^{x+1}=27 \)

1.) Resolver la ecuación: \( \left|\frac{1}{\log _{x}(a)}\right|^{\log _{h}(x)}=b^{2 b} \)
