3. Lesson 19: List and define the 3 types of parallelograms.

omework Use properties of logarithms to condense the logarithmic expression below. Write the expression as a single logarithm whose coefficient is 1 . Where possible, evaluate logarithmic expressions. \( 79.07 \%, 34 \) of 43 points \( 3 \ln x-4 \ln y \)

Acsignment (1) \( x^{2}+4 x+3=0 \)

Calculate \( \frac{\partial \vec{w}}{\partial \vec{u}} \),if \( \vec{w}=\binom{w_{1}}{w_{2}} \) where \( \left\{\begin{array}{l}w_{1}=x+2 y \\ w_{2}=3 x+4 y\end{array}\right. \) and \( \vec{u}=\binom{x}{y} \)

1) \( (x+5)^{2}= \)

Given that \( \pi \leq \theta<\frac{3 \pi}{2} \) and \( \sin \theta=-\frac{1}{4} \) Find the exact value for \( \cos \frac{\theta}{2} \) Indicate the question number and show your work on paper to upload to immediately after the exam.
