The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?

Sometimes questions that involve graphs will ask you to consider the effect of a changing factor or factors. problemâ€‹ statement: right arrow the line labeled d1 in the graph to the right shows the number of cups of lemonade that caroline and emily can sell at their lemonade stand at various prices. caroline and emily have noticed that they sell more lemonade whenâ€‹ it's hotter. click anywhere on the graph to open a window with a control labeled temperature. if you use the slider to change theâ€‹ temperature, the line will shift. change the temperature from 80 degrees to 100 degrees. â€‹question: right arrow at a price ofâ€‹ $0.50, how many more or fewer cups of lemonade do caroline and emily sell when the temperature is 100 degrees than when the temperature is 80â€‹ degrees? â€‹(note: indicate the change in cups of lemonadeâ€‹ sold: fewer will be a negative number and more will be a positiveâ€‹ number)
