If \( y = \frac { 3 } { 4 } x ^ { 2 } - \frac { 1 } { 3 } \) is changed to \( y = \frac { 3 } { 4 } x ^ { 2 } + 8 \) , which description of the change in the graph is correct? A. The change makes the graph narrower. B. The change inverts the graph. C. The change shifts the graph's axis of symmetry. D. The change moves the graph up the \( y \) -axis. 

construct a \( \triangle A B C \) such that : \( A B=6 \mathrm{~cm}, B C=4 \mathrm{~cm} \) and \( C A=5.5 \mathrm{~cm} \)

b) Triangle C is equilateral and has side length \( x \mathrm{~cm} \). The ratio of the perimeter of rectangle A to the perimeter of triangle C is \( 5: 4 \). Work out the value of \( x \).

16 Un terreno mide 180 m de largo por 160 m de ancho. El agricultor decide dividirlo en parcelas cuadradas iguales del máximo tamaño posible. a. ¿Cuánto medirán los lados de cada parcela? b. ¿Cuántas parcelas quedarán?

Example 5 : (Applications) A ball is thrown 6.4 m into the air. The ball falls, rebounds to \( 60 \% \) of its previous height, and falls again. If the ball continues to rebound and fall in this manner, fin the total distance the ball travels until it hits the ground for the fifth time.
