The keys are (from left to right) Access, Silence/Learn , and Repeat.

Orion Access keys: Access, Silence/Learn, and Repeat

Each of the Orion Access keys has multiple functions depending on how they are pressed, tapped, long pressed, or used in combination with the Access key. The following sections explain the use of the three Orion Access keys.

3.1.1 Access Key (A)

Tap the Orion A key followed by an Access Mode key to get the modified functionality for that particular key. For example Access followed by Repeat activates the spell mode.

· Holding the A key with a long press enters Orion settings which allows you to change settings such as speed and/or volume. Pressing and holding the A key again turns off Orion settings. Pressing a non-Orion settings key also exits the Orion settings. See Orion Settings for more accessibility information.

3.1.2 Silence/Learn Key (S/L)

Tapping the S/L key silences whatever is currently being spoken.
Pressing the A key followed by the S/L key turns off access functionality until one of the Orion Access keys is pressed or the calculator is turned off and on again. This is a good mode to use when an instructor would like to use the calculator without speech.

· Holding this key with a long press switches the calculator to Learn mode.

3.1.3 Repeat Key (↺R)

Tapping the ↺R key repeats the last spoken text.
Pressing the A key followed by the ↺R key spells out the last spoken text.
Press and hold the ↺R key to read the entire screen.

3.1.4 Learn Mode

The Orion TI-30XS is equipped with a Learn mode designed to assist you with locating keys and confirming their functionality. Learn mode can be used at any time.

NORM displays results with digits to the left and right of the decimal, as in 123456.78.

SCI expresses numbers with one digit to the left of the decimal and the appropriate power of 10, as in 1.2345678∗10⁵ (which is the same as 123456.78).

Note: In some restricted environments (for example function table, data editor, and the 2nd [recall] menu), the TI-30XS calculator may display E instead of ∗10ⁿ.

ENG displays results as a number from 1 to 999 times 10 to an integer power. The integer power is always a multiple of 3.

Note: ×10ⁿ is a shortcut key to enter a number in scientific notation format. The result displays in the numeric notation format set in mode.

FLOAT 0123456789 Sets the decimal notation mode.

FLOAT (floating decimal point) displays up to 10 digits, plus the sign and decimal.

0123456789 (fixed decimal point) specifies the number of digits (0 through 9) to display to the right of the decimal.

CLASSIC MATHPRINT™

CLASSIC mode displays inputs and outputs in a single line.

MathPrint mode displays most inputs and outputs in textbook format.

Note: The Orion TI-30XS has the ability to display math in both Classic and MathPrint™ mode. Classic mode displays input and output on a single line on screen and is fully accessible. Due to the difficulty in accessing information not on the screen, MathPrint mode is not accessible. When the Orion accessibility is muted, MathPrint mode still works and can be used by visual users of the calculator. If the MathPrint mode is active, a message is announced indicating that MathPrint is not supported and instruction is given to change to Classic mode.

Problem

Find angle A of the right triangle below. Then calculate angle B and the length of the hypotenuse c. Lengths are in meters. Round results to one decimal place.

The right triangle ABC has a right angle labeled C, positioned at the lower-left side of the triangle. Angle A is at the top-left and angle B at the lower-right side. The lengths of the sides are AC=3, CB=7, and AB=lower case c.

Right triangle ABC: right angle labeled C, positioned at the lower-left side
of the triangle; angle A positioned at top-left; angle B positioned at bottom-right. Side lengths: AC=3, CB=7, and
AB=lower case c.

Reminder:

tan A = 7/3 therefore m∠A = tan^-1 (7/3)
m∠A + m∠B + 90° = 180°
therefore m∠B = 90° − m∠A

c = √3²+7²

3.25 Probability

prb

This key displays two menus: PRB and RAND.

PRB contains the following options:

nPr	Calculates the number of possible permutations of n items taken r at a time, given n and r. The order of objects is important, as in a race.
nCr	Calculates the number of possible combinations of n items taken r at a time, given n and r. The order of objects is not important, as in a hand of cards.
!	A factorial is the product of the positive integers from 1 to n. n must be a positive whole number ≤ 69.

RAND contains the following options:

rand	Generates a random real number between 0 and 1. To control a sequence of random numbers, store an integer (seed value) ≥ 0 to rand. The seed value changes randomly every time a random number is generated.
randint(	Generates a random integer between 2 integers, A and B, where A ≤ randint ≤ B. Separate the 2 integers with a comma.

Examples

nPr	8	Result = 8
	prb, 1	Result = PBR 1:
	3, enter	Result = 336
nCr	52, prb, 2, 5, enter	Result = 2598960

clear, 15, down arrow, clear, 3, down arrow, down arrow, enter	Result = x=15

After searching close to x = 18, the point (18, 324) appears to be the vertex of the parabola since it appears to be the turning point of the set of points of this function. To search closer to x = 18, change the Step value to see points closer to (18, 324).

Problem

A charity collected $3,600 to help support a local food kitchen. $450 will be given to the food kitchen every month until the funds run out. How many months will the charity support the kitchen?

Reminder: If x = months and y = money left, then y = 3600 - 450x.
