suppose a set of 10 beads were laid in a line where each successive bead had a diameter that was 3/4 of the diameter of the previous bead. If the first bead had a diameter of 24mm, determine the total length of the line of the beads. Express your answer to the nearest millimetre.

Sketch the graph y= 1/3x-6, outlining the steps used.

when an object is dropped from the top of a 75 ft tall building, the object will be h feet above the ground after t seconds,where t = $\frac{1}{4}\sqrt{75-h,}h\le75$‍14 √75−h,h≤75. How far above the ground will the object be after 1 s? Later verify answers.
