Answer: The answer is B.
Step-by-step explanation:
Angle ABC is a straight angle, which is 180 degrees, so you can rule out answers C and D.
For angle EBG, simply count the measures of the angle on the protractor. From the right, you start at 55. You end at 100. Subtract 55 from 100 to get a measure of 45 degrees.
Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.
Step-by-step explanation:
From my work I believe it should be the third one.
Answer:
f(r) = 2πr
Step-by-step explanation:
You know the formula for circumference in terms of radius is ...
C = 2πr
You are being asked to write this as a function named "f". That will be ...
f(r) = 2πr
