Question:This probably gets asked a lot, sorry!
I am a sophomore retaking Algebra 1. It is so stressful for me already.. I am trying my best.
Answers:use perhaps the Riemann's dzeta function
Question:Is there a math calculator that does algebra factoring and shows the work?
Answers:Indeed, it is known as one's brain
Question:1. The length of a rectangle is 5 cm more than 4 times its width. If the area of the rectangle is 76 cm^2, find the dimensions of the rectangle to the nearest thousandth.
2. The height h in feet of an object after t seconds is given by the fraction h = -16t^2 + 30t + 8. How long will it take the object to hit the ground? Round answer to the nearest thousandth.
Answers:the first is a word problem; you set up two equations and solve simultaneously:
if the length is 4 * the width + 5 cm, you have one equation:
l = 4w + 5
and if the area is 76 cm^2, its length * width is 76, so you set up the other equation:
l * w = 76.
this means that:
w = 76/l
substitute this into the first equation:
l = 4(76/l) + 5.
you can solve for l:
l^2 - 5l -304 = 0
you need the quadratic equation to solve this, and you come up with
l= 20.1, w = 3.78
the other problem just needs the quadratic equation for.
either as a calculator program or:
also, you can approximate through factoring, but the answer is:

Java Fraction Calculator :Okay, this was around one hour of work with JAVA netbeans. I was only programming java in the past 2 1/2 months, so I'm good... I think and I hope. The minigame was around 15 minutes and I think it may still contain some bugs
