Q:
10. The perimeter of a rectangular plot of land is 72 meters and its area is \( 308 \mathrm{~m}^{2} \). What are the
dimensions of the property?
Q:
QUESTION 3
3.1 Given the number pattern \( 2 ; y ; 8 ; \ldots \)
Determine the value of \( y \) if:
3.1.1 The number pattern is linear.
3.1.2 The number pattern is quadratic and \( T_{4}=2+5 y \).
3.2 In a linear number pattern, the \( 19^{\text {th }} \) term is 40 and the \( 7^{\text {th }} \) term is 16 .
Thus, determine the first two terms.
3.3 The general term of a quadratic number pattern is \( T_{n}=n^{2}+2 n-15 \).
Determine which term has a value of 20 .
Q:
9. Use any method to solve the system: \( \left\{\begin{array}{c}x^{2}+y^{2}=9 \\ 9 x^{2}+4 y^{2}=36\end{array}\right. \)
Q:
-11) \( \frac{22^{4} \cdot 8^{4}}{121^{4} \cdot 4^{6}}= \)
Q:
Solve for \( r \).
\( 3^{r}+3^{3-r}=28 \)
Q:
Write the function whose graph is the graph of \( y=(x+4)^{2} \), but is reflected about the \( x \)-axis.
\( y=\square \) (Simplify your answer.)
Q:
If \( f(x)=\left\{\begin{array}{ll}2 x-5 & \text { if }-2 \leq x \leq 4 \\ x^{3}-4 & \text { if } 4<x \leq 5\end{array}\right. \), find: (a) \( f(0) \), (b) \( f(1),(c) f(4) \), and \( (d) f(5) \).
(a) \( f(0)=\square \)
(b) \( f(1)=\square \)
(c) \( f(4)=\square \)
(d) \( f(5)=\square \)
