Answer:
The answer is D
Step-by-step explanation:
This is because each x maps to one, and ONLY ONE, y value. The other choices had x values map to more than one y value, so they aren't functions.
I belive the answer is no. Tell me if im doing this wrong, but the square root of 380 is a decimal number.
The answer is d because A = pi times r squared and 10 divided by pi round to the nearest hundredth is 3.18
An investigator doesn't change the value of a variable parameter because it changes by itself since a variable parameter is factors that change or vary throughout the experiment. Hope this answers the question. Have a nice day. Feel free to ask more questions.
first is proportional. y is 1 and 1/4 times x
second is not proportional.
reason? divided any y value by its corresponding x value and you'll keep getting 1.25, or 1 and 1/4. and the second one is not proportional because dividing the y values by their corresponding x value will give different answers.
maybe im wrong maybe im right you choose to trust me or not.
