Look at this set of ordered pairs: \[ \begin{array}{l}(3,14) \\ (17,-2) \\ (9,13) \\ (17,9)\end{array} \] Is this relation a function? yes no

A population of 30 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain up to 600 deer. Absent constraints, the population would grow by \( 60 \% \) per year. Estimate the population after one year \( p_{1}=\square \) Estimate the population after two years \( p_{2}=\square \) Question Help: D Post to forum

1. Choose the correct answer from the given ones : \( \begin{array}{llll}\text { 1 If } X=\{2\}, Y=\{3,4\} \text {, then } n\left(X^{2}\right) \times \mathrm{n}(\mathrm{Y})=\ldots \ldots \ldots \ldots \\ \begin{array}{llll}\text { (a) } 1 & \text { (b) } 2 & \text { (c) } 3 & \text { (d) } 4\end{array}\end{array} \).

3 The middle proportional between the two numbers 3 and 12 is ............. \( \begin{array}{llll}\text { (a) } \pm 3 & \text { (b) } \pm 4 & \text { (c) } \pm 6 & \text { (d) } \pm 12\end{array} \)

\[ S_{n}=1^{3}+2^{3}+3^{3}+\cdots+n^{3} \] Calcule \[ S_{35} \]

\( \frac{21}{35}=\frac{}{100} \)
