Jill's coach used a computer program to help her improve the distance she can throw a softball. The computer gave
a readout of the path of her best throw. The path of this throw was represented by the quadratic equation
y = -0.15x + 1.3x + 4, where x represents the number of feet the ball traveled and y represents the height of the
ball in feet. Use the graphing calculator to graph the equation. At what distance did the ball hit the ground? Round
your answer to the nearest hundredth.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

only 2 outcomes have passed the given condition.

step-by-step explanation:

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
