About Stephen King Expertise I can help with all word problems for any math (including college math). I can show how to set up the problem, and how I came about that solution. Some word problems rely on many facets of math to solve, and it`s important for someone to realize that.
Experience I'm a math major currently going for my Bachelor's degree. I was involved in the Excel program at Oregon State University, a program to advance students' understanding of math.
Question Hi there Stephen. How are you doing today? This problem is giving me trouble. I was wondering if you can help me. Here it is:
The height, in feet, above the ground of a ball thrown straight up with an initial velocity of 160ft/sec was given by using the formula:
h(t) = -162t2 + 160t + 4
where t stood for the number of seconds after the ball had been thrown. Fine the values of t for which the height of the ball was 260 feet.
Answer Hey Damon.
Ok, I'm not sure which math you're taking, but using Calculus will yield that there is no solution. The maximum height that the ball goes is approx 43.5 ft. So the ball never got to the height of 260 feet.
If you're not in Calculus, think of it like this: plug in values in for t, from 1 on up. You'll see that because of the t^2 value, and the negative sign in front of the 162 that the ball will never go that high.
You can also graph the function on a graphing calculator and see that the heighest the ball goes is nowhere near 260 feet.
