Yes you can do thatUsing TI-83https://www.calculatorti.com/calculator-help/5816/can-i-play-games-on-a-rugelar-old-ti-83?show=5817#a5817Sat, 08 Jun 2024 00:39:24 +0000Answered: Y= x^2 -10x -53
https://www.calculatorti.com/calculator-help/5814/y-x-2-10x-53?show=5815#a5815
I assume that you are trying to find the roots of "y = x^2 - 10x - 53".<br />
<br />
The correct way to solve this one is to "complete the square".<br />
But, on a TI-84 Plus, you can either graph it and see where it crosses the x axis by using the trace function, or you can use the "Apps" button for 9:PlySmlt2 to get to the Polynomial and Simultaneous Equation solver. Use the Polynomial Solver to get approximations of x1=13.83176 and x2=-3.831676.<br />
An "exact" answer can be found by either completing the square, or buying a calculator that has a CAS (Computer Algebra System) built-in, like the TI-89 or one of the other advanced TI models.<br />
To complete the square, start by setting the x expression equal to zero, and moving the constant term to the other side.<br />
x^2 - 10x = 53<br />
Next, take the x coefficient (-10 in this case), divide it by 2 and square the result to get 25. Add the 25 to both sides.<br />
x^2 - 10x + 25 = 53 + 25<br />
At this point you've got a perfect square on the left side. x^2 - 10x + 25 can be replaced by (x - 5)^2. On the right side, just add them together to get 78.<br />
(x - 5)^2 = 78<br />
Subtract 78 from both sides to get:<br />
(x - 5)^2 - 78 = 0<br />
You now have the difference of two squares on the left side (assuming you know the square root of 78) and can re-write as:<br />
((x - 5) + sqrt(78)) ((x - 5) - sqrt(78)) = 0<br />
This means the roots are:<br />
x = 5 - sqrt(78) or x = 5 + sqrt(78)Using TI-84 Plushttps://www.calculatorti.com/calculator-help/5814/y-x-2-10x-53?show=5815#a5815Thu, 16 May 2024 21:06:36 +0000Answered: how to factor polynomials
https://www.calculatorti.com/calculator-help/5810/how-to-factor-polynomials?show=5812#a5812
It's difficult to "factor" a polynomial on a TI-84. But you can find the "roots" of a polynomial via a couple of different methods.<br />
<br />
1. Graph the polynomial. The points where it crosses the x-axis are the "real roots" of the polynomial. Let's graph y=x^2+x-6 and you see it cross the x-axis at x=2 and x=-3. That means two of the factors are (x-2) and (x+3).<br />
<br />
2. If it's a newer TI-84 Plus, it will have an APP (under the 'APP' key) named "PlySmlt2" which includes a polynomial root finder. You can use that to find the roots, and turn those into factors.Using TI-84 Plushttps://www.calculatorti.com/calculator-help/5810/how-to-factor-polynomials?show=5812#a5812Sun, 21 Apr 2024 16:35:08 +0000Answered: Find the center of mass of y= x^2 and y= x+2

https://www.calculatorti.com/calculator-help/5727/converting-a-ti-83-program-to-ti-89?show=5781#a5781
<p>No. The "asm" for the TI-83/84 machines is actually machine language for the Zilog Z-80 microprocessor which those calculators are based on. The "asm" for the TI-89 is built around the Motorola MC68000 processor which is a completely different machine/architecture. There is no good way to translate from one to the other without a complete re-write of the entire program.</p>

https://www.calculatorti.com/calculator-help/5802/why-isnt-1-2sin-7pi-6-0?show=5806#a5806
I don't own a TI inspire CX II, but I'm going to guess the difference lies in "rounding error". On my TI-84 Plus, when I enter "sin(7PI/6)" it returns "-.5". If it returns anything else, you probably are seeing a "rounding error" somewhere in the sin() function. For all practical purposes, any computer that gives a floating point answer with an exponent of less than -7 can be considered to be zero.Using TI-83https://www.calculatorti.com/calculator-help/5802/why-isnt-1-2sin-7pi-6-0?show=5806#a5806Wed, 13 Mar 2024 06:00:39 +0000Answered: solve for the hole 5(x-2)(x+2)/-4(x-5)(x+2)

You've presented a rational expression of "(5(x-2)(x+2)) / (4(x-5)(x+2))". I assume by "hole", you mean places where the domain is not defined. In this case, the expression is not defined if the denominator is equal to zero. This denominator is equal to zero whenever (x-5)=0 or (x+2)=0, or whenever x=5 or x=-2.Using TI-83https://www.calculatorti.com/calculator-help/5800/solve-for-the-hole-5-x-2-x-2-4-x-5-x-2?show=5805#a5805Wed, 13 Mar 2024 05:44:31 +0000Answered: does the ti-83 plus come with games

https://www.calculatorti.com/calculator-help/5756/11x-%E2%88%92-20y-5?show=5780#a5780
That's a very nice linear equation in "Standard Form". It's arranged so that the x variable is first with a positive coefficient, the y variable is second and the constant term is on the right side of the equation by itself.<br />
<br />
I'm not certain what you want to do with it, but we can put it in "slope-intercept" form where we simply solve it for "y".<br />
<br />
In this case start by adding "-11x" to both sides to get:<br />
11x - 20y -11x = 5 - 11x<br />
next, combine the like x terms on the left side:<br />
<br />
11x - 11x -20 y = 5 - 11x<br />
-20y = 5 - 11x<br />
divide both sides by -20 to get:<br />
y = 5/-20 -11x/-20<br />
y = (11/20)x - 1/4<br />
This shows that it is a linear equation with a slope of 11/20 and a y intercept of 1/4.<br />
Since it's in slope/intercept form you can enter it in the graph editor using the [y=] key as:<br />
y1 = 11x/20 -1/4<br />
and then press the [GRAPH] key to graph the equation.Using TI-83https://www.calculatorti.com/calculator-help/5756/11x-%E2%88%92-20y-5?show=5780#a5780Wed, 22 Nov 2023 05:30:55 +0000Answered: 1.21=(1.1)^n
https://www.calculatorti.com/calculator-help/5752/1-21-1-1-n?show=5778#a5778
<p>To solve the following:<br>
1.21 = (1.1)^n<br>
You know that the inverse of exponentiation is the logarithm, so take the log (base 10) or ln (base <em>e</em>) or whatever base of both sides. For fun we'll take it to base 10.</p>
<p>log(1.21) = n * log(1.1)<br>
now divide both sides by log(1.1) to get:<br>
log(1.21)/log(1.1) = n<br>
Use your calculator to divide log(1.21) by log(1.1) and find the result "2", So...<br>
n = 2<br>
The trick here is to know that when you take the log(a^n) you get n * log(a). You can then divide by log(a) to get "n" by itself.</p>TI-83 Programshttps://www.calculatorti.com/calculator-help/5752/1-21-1-1-n?show=5778#a5778Mon, 20 Nov 2023 04:56:13 +0000Answered: 3x^4 – 5x^2 – 2 = 0

In this case, the order of the polynomial tells you whether it is even or odd. The polynomial:<br />

https://www.calculatorti.com/calculator-help/62/f-x-4x5-%E2%88%92-240x3?show=5775#a5775
First, your expression "4x5 - 240x3" makes no sense unless you're actually using exponents. If so, then the proper way to write it out in here and on your TI-89 is:<br />
f(x) = 4*x^5 - 240*x^3<br />
<br />
If that's the case then taking the first derivative of f(x) gives:<br />
<br />
f'(x) = 20*x^4 - 720*x^2<br />
If you factor that, you will find the local maxima and minima of the function at:<br />
f'(x) = (20*x^2) * (x-6)*(x+6)<br />
The zeroes of this function give us the local maxima and minima as (-6,20736), (0,0) (6,-20736)<br />
<br />
To find the inflection points of f(x), take it's 2nd derivative and find the zeros of that function.<br />
f''(x) = 80x^3 + 1440x<br />
factor that into:<br />
f''(x) = (80x)(x^2 - 18) = (80x)(x+sqrt(18))(x-sqrt(18))<br />
So the inflection points occur at x = {-4.2, 0, 4.2}Using TI-89https://www.calculatorti.com/calculator-help/62/f-x-4x5-%E2%88%92-240x3?show=5775#a5775Sun, 19 Nov 2023 06:58:35 +0000Answered: How to write a program that puts a function into Y1

Your question makes no sense unless you've accidentally typed and extra "y" in your equation.<br />
If what you really meant for your equation was "y = 1x - 5", then this is an equation in slope-intercept form with a slope of 1 and a y-intercept of 5. To find the x-intercept, solve the equation for x to get "x = y + 5".

https://www.calculatorti.com/calculator-help/5755/find-the-slope-of-y-intercept-of-the-graph-of-the-equation-y-3x?show=5768#a5768
This is a trick question, right?<br />
The equation is already in slope/y-intercept form of "y = mx + b" where m is the slope and b is the y-intercept. In this case, the slope is 3 and the y-intercept is -6.Using TI-84 Plushttps://www.calculatorti.com/calculator-help/5755/find-the-slope-of-y-intercept-of-the-graph-of-the-equation-y-3x?show=5768#a5768Sat, 18 Nov 2023 05:59:44 +0000Answered: can you port the Shrek movie to a calculator?

Brady,You asked "can you port the Shrek movie to a calculator?"<br />
Answer: There would certainly be copyright restrictions on doing so. Also, the monochrome screen of the TI-84 Plus would produce a lousy picture, and sound would be equally bad given that there are no speakers on the TI-84 Plus calculator.Using TI-84 Plushttps://www.calculatorti.com/calculator-help/5760/can-you-port-the-shrek-movie-to-a-calculator?show=5767#a5767Sat, 18 Nov 2023 05:54:17 +0000Answered: Divide 6x^2 -7x -2 by 2x -1
https://www.calculatorti.com/calculator-help/5761/divide-6x-2-7x-2-by-2x-1?show=5766#a5766
<p>You can graph the answer directly by creating two graphs as:</p>
<p>Y1 = 6x^2 -7x - 2<br>
Y2 = 2x - 1<br>
deselect both of the above and graph the 3rd equation (the answer) as:<br>
Y3 = Y1(N)/Y2(N)<br>
At this point, graphing it doesn't tell you much. But you can use that graph to check the graph of the ACTUAL answer which can be found by simply doing the division to get a 4th equation of:<br>
Y4 = 3x - 2 - 4/(2x-1)<br>
You'll notice that the graphs of Y3 and Y4 match which proves that Y4 is the correct answer.</p>Using TI-84 Plushttps://www.calculatorti.com/calculator-help/5761/divide-6x-2-7x-2-by-2x-1?show=5766#a5766Sat, 18 Nov 2023 05:32:59 +0000Answered: Points of Inflection in f(x)=x^3-15x
https://www.calculatorti.com/calculator-help/5762/points-of-inflection-in-f-x-x-3-15x?show=5765#a5765
I'm assuming that the question is "Given the function "f(x) = x^3 - 15x", what are the points of inflection?<br />
<br />
Points of inflection are the zeros of the 2nd derivative of a function. For this function, the derivatives are:<br />
<br />
f(x) = x^3 - 15x <- original function<br />
f'(x) = 3x^2 - 15 <- 1st derivative<br />
f''(x) = 6x <- 2nd derivative<br />
<br />
Since the 2nd derivative has only one zero solution of "x = 0", the original function has x=0 as the inflection point.Using TI-83 Plushttps://www.calculatorti.com/calculator-help/5762/points-of-inflection-in-f-x-x-3-15x?show=5765#a5765Sat, 18 Nov 2023 05:04:34 +0000Answered: Line ℓ1 has the equation y= – x+5 and line ℓ2 has the equation x+y= – 1. Find the distance between ℓ1 and ℓ2.
https://www.calculatorti.com/calculator-help/5763/line-has-the-equation-and-line-equation-find-distance-between?show=5764#a5764
That's an interesting question. If you re-write both equations in standard form, you find:<br />
<br />
y1(x) = -x + 5<br />
<br />
y2(x) = -x - 1<br />
<br />
Both equations have the same slope (-1), but different y-intercepts (5 and -1). So the vertical distance (along the y-axis) is simply 5 - (-1) = 6.<br />
<br />
But if we're talking about about the shortest distance between them, then we need to find a line perpendicular to them both and see how far apart the intersection points are using the distance formula (Pythagorean Theorem). The perpendicular line will have a slope that is the negative reciprocal of -1 which is a new slope of -(1/-1) = 1. Just for fun we'll pick a y-intercept of 5 to match y1(x) and get a new line of:<br />
<br />
y3(x) = x + 5<br />
<br />
This y3(x) intersects y1(x) at (0,5). To find the intersect of y3(x) with y2(x), we set them equal to each other and solve for x.<br />
-x - 1 = x + 5<br />
-6 = 2x<br />
x = -3<br />
Subsititute for x=-3 in EITHER y3 or y2 and we get y=2, so a pair of points to look between are (0,5) and (-3,2). Find the distance between these two points, and you'll have the distance between the lines.<br />
<br />
Sqrt((0-(-3))^2 + (5 - 2)^2) = Sqrt(3^2 + 3^2) = 3*Sqrt(2) = 4.2426...<br />
<br />
So, the final answer(s) are, Vertical distance between the parallel lines = 6, and perpendicular distance between the parallel lines = 3*Sqrt(2) or approximately 4.2426...Using TI-83https://www.calculatorti.com/calculator-help/5763/line-has-the-equation-and-line-equation-find-distance-between?show=5764#a5764Sat, 18 Nov 2023 00:47:26 +0000(x-1)^3(x+4)^2
