A triangle has sides of lengths \( 30,39,54 \mathrm{~m} \). Largest angle \( =\square_{2 \text { decimal places }} \)

Simplify the following \( \frac{2^{a+1}-2^{a-1}}{2^{a}} \) \( \frac{x^{2}-x+1}{x^{3}+1} \div \frac{2 x}{2 x+2} \)

3ny ther stadert on the text Question 14 Find the dertiative of \( h(x)=9^{(\cos s)} \)

Convert the complex number from polar form to rectangular form, \( a+b i \). \[ 3.1\left(\cos \frac{3 \pi}{4}+i \sin \frac{3 \pi}{4}\right) \]

Find the principal needed now to get the given amount; that is, find the present value. To get \( \$ 1000 \) after \( 1 \frac{1}{4} \) years at \( 4 \% \) compounded daily The present value of \( \$ 1000 \) is \( \$ \square \). (Round to the nearest cent as needed.)
