[Done] Solve the equation on the interval [tex]$0 \leq \theta\ \textless \ 2 \pi$[/tex]. [tex]$2 \sin \theta+1=0$[/tex] What are the solutions to [tex]$2 \sin \theta+1=0$[/tex] in the interval [tex]$0 \leq \theta\ \textless \ 2 \pi$[/tex]? A. The solution set is $\square$ {As} (Simplify your answer. Type an exact answer, using [tex]$\pi$[/tex] as need expression. Use a comma to separate answers as needed.) B. There is no solution.

[Done] Given the polynomial function [tex]$f(x)=2(x+1)^2(x-2)^2(x-3)$[/tex]. i) What is the degree of [tex]$f$[/tex]? ii) Determine the zeros of [tex]$f$[/tex] and their multiplicities. Also, determine whether the graph of [tex]$f$[/tex] crosses or touches the [tex]$x$[/tex]-axis at each zero. iii) Determine its [tex]$y$[/tex]-intercept. iv) Determine the end behavior of [tex]$f$[/tex]. v) Sketch the graph of the polynomial function. Make sure your graph shows all intercepts and exhibits the proper end behaviour.

[Done] Type the correct answer in each box. Use numerals instead of words. A race car is driven by a professional driver at 99 miles per hour. What is this speed in $\frac{\text { kilometers }}{\text { hour }}$ and $\frac{\text { kilometers }}{\text { minute }}$ ? 1 mile = 1.61 kilometers 1 hour = 60 minutes Round your answers to the nearest tenth. The speed is equivalent to $\square$ $\frac{\text { kilometers }}{\text { hour }}$, or $\square$ kilometers per minute
