How do you find the solution on a TI 84?

Tell your TI-84 calculator to solve the equation by selecting the “SOLVE” key. Since the word “SOLVE” is in green over the “ENTER” key, you must press the “ALPHA” key followed by the “ENTER” key to solve your equation. The answer is displayed on your screen on the second line, A=6.

How do you solve Pie R 2h?

1 Answer

  1. Divide both sides by π
  2. Divide both sides by h.
  3. Take ±√ both sides.
  4. ±√Vπh=r.
  5. Radius, r , is not a negative value, so just keep the positive.
  6. r=√Vπh.

What is r in I PRT?

Investment problems usually involve simple annual interest (as opposed to compounded interest), using the interest formula I = Prt, where I stands for the interest on the original investment, P stands for the amount of the original investment (called the “principal”), r is the interest rate (expressed in decimal form).

Is a ΠR 2 quadratic equation?

A = πr² in a circle of radius r. Area is quadratic in r because circles are 2-D, while r (the radius) is 1-D.

Can TI-84 Plus solve equations?

The Equation Solver on your TI-84 Plus calculator is a great tool for solving one-variable equations. The Solver is also capable of solving an equation for one variable given the values of the other variables. Keep in mind that the Solver can only produce real-number solutions.

What is ΠR 2h?

The volume V of a cylindrical barrel is given by the formula. V = πr2h, where r is the barrel’s radius and h is the barrel’s height. This formula gives the volume V in terms of r and h.

What is a ti-83/ti-84 calculator used for?

The TI-83/TI-84 calculator is an essential tool for any student in a math or science course. Solving for unknown variables is a common problem that students may run across while taking these courses.

Will this program work on the TI-84 Plus CE?

READ:   How do you come up with an interesting question?

Technically yes, but it isn’t exactly ideal. This program was originally designed for the TI-84 Plus C Silver Edition, but will work on the TI-84 Plus CE as well. I say it “isn’t exactly ideal” because it is slow, and the color scheme isn’t the best.

How to calculate the correlation coefficient between two variables on TI-84?

You can use the following steps to calculate the correlation coefficient between two variables on a TI-84 calculator: Step 1: Turn on diagnostics. First, we need to turn on diagnostics. To do so, press 2nd and then press the number 0. This will take us to the CATALOG screen.
