Charlotte drives 64 mph for the first 3 hours of her trip and 92 mph for last 4 hours.

german

Answer:

80 mph

Step-by-step explanation:

$\boxed{\sf Distance=Speed \times Time}$

<u>First leg of trip</u>

Speed = 64 mph
Time = 3 hours

$\implies \sf Distance =64\times 3 = 192\:miles$

<u>Second leg of trip</u>

Speed = 92 mph
Time = 4 hours

$\implies \sf Distance=92 \times 4 = 368\:miles$

$\boxed{\sf Speed=\dfrac{Distance}{Time}}$

To find the average speed:

$\begin{aligned}\implies \sf Average\:speed & = \sf \dfrac{Total\:distance}{Total\:time}\\\\ & = \sf \dfrac{192+368}{3+4}\\\\& = \sf \dfrac{560}{7}\\\\ & = \sf 80\:mph\end{aligned}$

Solve. Find all solutions in [0,2).5 secx cotx+5 secx+ cotx+1=0

Dmitrij [34]

$\begin{gathered} 5sec(x)cot(x)+5sec(x)+cot(x)+1=0 \\ Factoring \\ (cot(x)+1)(5sec(x)+1)=0 \\ cot(x)+1=0 \\ cot(x)=-1 \\ x=cot^{-1}(1) \\ x=\frac{3\pi}{4} \\ \\ 5sec(x)+1=0 \\ 5sec(x)=-1 \\ sec(x)=\frac{-1}{5},\text{ there is no solution} \\ Hence \\ All\text{ solution are }\frac{3\pi}{4}+\pi n,\text{ where n=1,2,3...} \\ \\ \end{gathered}$
