Final answer:
False, you can use named ranges in formulas. 'Suggestion' is closest in meaning to 'hypothesis'. False, the graph of an object speeding up is not a straight line.
Step-by-step explanation:
The answer to the first question is b. False. In certain spreadsheet programs, you can indeed use column and row titles within formulas to refer to related data by name. This feature is known as using named ranges and is particularly useful for making formulas easier to read and maintain.
For the second question, the word closest in meaning to hypothesis is d. suggestion. A hypothesis is a proposed explanation for a phenomenon, made as a starting point for further investigation.
Regarding the third question, b. False is the correct answer. The position vs time graph of an object that is speeding up shows a curve that gets steeper over time, not a straight line. A straight line would indicate a constant speed, not acceleration.
