Answer:

Proportional

Step-by-step explanation:

Proportional functions can be written as $y=kx$ , where $k$ is some constant of proportionality. Plugging in (x,y) pair into this function will yield a constant of proportionally of $k=\frac{3}{2}$ and since this constant is maintained through all the coordinate pairs in the table, the table is proportional.

NikAS [45]

Step-by-step explanation:

$y = log_2 x^2 \\ \therefore y = \frac{log x^2}{log2}\\ (By\:change\:of\:base\:law) \\ \\ \therefore y = \frac{2log x}{log2}\\\\ differentiating \: both \: side \: w \: r \: t \: x. \\ \\ \frac{dy}{dx} = \frac{2}{log2} \bigg(\frac{d}{dx} log x \bigg) \\ \\ \therefore \frac{dy}{dx} = \frac{2}{log2} \bigg( \frac{1} {x} \times \frac{d}{dx} x \bigg) \\ \\ \therefore \frac{dy}{dx} = \frac{2}{log2} \bigg(\frac{1}{x} \times 1\bigg) \\ \\ \huge \red{ \boxed{\therefore \frac{dy}{dx} = \frac{2}{xlog2}}}$

Answer:

$\large \boxed{\$10000.00}$

Step-by-step explanation:

We can use the formula for continuously compounded interest.

$\begin{array}{rcl}A & = & Pe^{rt}\\13231.30& = & Pe^{0.035 \times 8}\\& = &Pe^{0.28}\\& = & P\times 1.3231298\\P & = &\dfrac{13231.30}{1.3231298}\\\\&=&\mathbf{10000.00}\\\end{array}\\\text{The initial deposit was $\large \boxed{\mathbf{\$10000.00}}$}$
