Question details

ENTERING NUMERICAL ANSWERS This question asks for a number answer. Acceptable answers include whole numbers, integers (negative numbers), and decimal values. (These questions will normally require you to do calculations by hand or with a computer before you enter a final answer.) In special cases, you may need to enter DNE for Does not exist, oo for infinity, or -oo for negative infinity If your answer is not an exact value, youll want to enter at least 3 decimal places unless the problem specifies otherwise Try it out: Enter the number 45.3759 below exactly (no rounding) Preview Enter the number 45.3759 rounded to the nearest hundredth (two decimal places) Preview Enter the result of 45.3759 : 0 PreviewENTERING FRACTIONS, REDUCED FRACTIONS AND MIXED NUMBERS This question asks for a fraction, a reduced fraction, and a mixed number Enter fractions like 2/3 for . For this type, the fraction does not need to be reduced, sois considered the same as For a reduced fraction answer, be sure to reduce your fraction to lowest terms. If reduced, and would be marked wrong is the correct answer, - is not 10 For both fraction and reduced fraction type problems, improper fractions are OK, likebut mixed numbers will not be accepted. For a mixed number problem, enter your answer like 5 1/3 for 5 Improper fractions will not be accepted. Also, be Try it here. Use the Preview button to see how the computer is interpreting what you typed. A) Enter 26 B) Enter in reduced form: 13 Preview(Does NOT have to be reduced to lowest terms) 9 Preview MUST be reduced to lowest terms) 18 C) Enter 13 + Preview as a mixed number. (Make sure you reduce, if necessary.) 18This question asks for a number or a calculation. You can enter whole numbers, negative numbers, or decimal numbers. If you enter a decimal value, be sure to give at least 3 decimal places Alternativelv, vou can enter mathematical expressions. Some examples Enter To get sqrt(4) V4 2 5-3 312 log(100) log(100)2 Note that for functions like log and sqrt, you must use parentheses. log(100) is good, but log100 and log 100 will not work. Try it here. Use the Preview button to see how the computer is interpreting what you typed. Enter Preview Enter Preview Preview 2*- 5 Enter log(4) PreviewENTERING ALGEBRAIC EXPRESSIONS OR EQUATIONS This question asks for an algebraic expression. With these types of questions, be sure to use the variables indicated. In your answer, you can also use mathematical expressions for numerical calculations Examples To get 3a2 5Notice the symbol for powers Type Comment 3x 2+5 || Notice vou need parentheses around the numerator and denominator sqrt(x-5)V-5Be sure to put parentheses around the input: sqrt(x+3) is OK, but sqrtx+3 or sqrt x+3 is not. Parentheses keeps the r 7 together as the power You may need nested parentheses Fractions are automatically formatted vertically when previewed Unless the problem gives specific directions, any algebraically equivalent expression is acceptable. For example, if the answer was (2)(z +3), then ( 3) ( + 2) and (3+z)(2+z) would also be acceptable Try it here. Use the Preview button to see how the computer is interpreting what you typed. A) Enter the expression 525x4 Your input Preview 8y 2 n_ B) Enter the expressio Your input C) Enter the expression w2 +5yw+I Your input Preview Preview

ENTERING COORDINATE POINT ANSWERS Some questions ask for ordered pairs to give the coordinates of a point on a plane Enter these answers as youd write the ordered pair: (x, y) For example, the point where 3 and y-5 would be written: (3,5) If the question asks for several points, list each point separated with commas, like: (1,2), (3,4) Try it now. Enter the points shown on the graph below Points
