Use the four-step procedure for solving the following variation problem. The height that a ball bounces varies directly as the height from which it was dropped. A tennis ball dropped from 11 inches bounces 8.8 inches. From what height was the tennis ball dropped if it bounces 64 inches? The tennis ball needs to be dropped from the height of it bounces 64 inches. (Type an integer or a decimal.)

Graph the parabola. \[ y=(x+2)^{2}+4 \] Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.

Elsa løper ei løype som er \( 1,75 \mathrm{~km} \) kortere enn den William loper, Tariq løper \( 15,95 \mathrm{~km} \), og det er 2,43 lenger enn William. Hvor langt løper Elsa og William?

Graph the parabola. \[ y=(x-1)^{2}+5 \] Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.

1.3 \( a \times a \times a \times a \) canbe expressed as. (a) \( 4 \times a \) (b) \( 4^{a} \) (c) \( 9 / 4 \) (d) \( a^{4} \) 14 The HCF of 40 and 60 . (a) 10 (b) 5 (c) 20 (d) 12

Solve the inequality. Express the solution set in set-builder notation and interval notation. Graph the solution set on a real number line. \( \frac{1}{2}(n-4)>n+5 \)
