Answer:
hello and thank u for asking questions
the correct answers are...
A. is correct because an obtuse angle is an angle that measures over 90°
B. is incorrect because the acute angle is less than 90°
C. is correct because a reflex is "Reflex angles are angles measuring greater than 180 degrees and less than 360 degrees. The measure of a reflex angle is added to an acute or obtuse angle to make a full 360 degree circle"
D. is incorrect because if it is less than 2 but greater than 4 that does not make any sence
hopes this help pls mark brainiest and have a great and wonderful rest of your day
The better deal would be 1 gallon for three dollars because i gallon of milk is more than 2 quarts
Answer:
A. neither a relation nor a function
Step-by-step explanation:
A relation between two sets is a collection of ordered pairs containing one object from each set.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Quadratic equations are not functions. Quadratic equations are not a function because they touch two points that is on the same y-axis. Furthermore, if they are two points that have the same x axis, then it is not a function either. It doesn't have a relation either because there are two outputs that are the same by the x axis for 3x^2 - 9x + 20. Those are x = 1 and x = 2. For proof, you can plug both of them in.
3(1)^2 - 9(1) + 20 = 14
3(2)^2 - 9(2)+ 20 = 14
Both answers have 14 as the y-axis/output. This proves that this quadratic equation is not a relation either. Therefore, this equation is neither a relation nor a function.
Use a protractor. Place the whole on the dot of the angle and you should know how to do the rest.
