The standard form of a circle is:
Your center is and your radius is
Plug them into the equation and you get
The correct answer is D.
Problems a through c are asking you what the values would be at those values.
What will the value of be at ? Let's look at the graph.
It seems at , , meaning that
Let's do the same for the others.
At ,
At ,
For the last question, it is giving us the value and asking us which values would give us that.
At , .
*Note* this function is continuous to the right, meaning that there is another point where .
Hope this helps.
頑張って!
Answer:
Correct answer is C.
Step-by-step explanation:
m + 3s = 50
the total number of questions is 20. since the paper is made of only multiple choice and short answer questions, the sum of the multiple choice and short answer questions should be 20.
since multiple choice is 'm' and short answer is 's'
then m + s = 20
but theres no option for that
if we take the number of points
points for 1 multiple choice question - 1
then points for m number of multiple choice questions = 1 * m = m
points for 1 short answer - 3
then points for s number of short answer question = 3 * s = 3s
then total number of points = m + 3s
and the total number of points = 50
therefore
m + 3s = 50
this is the correct answer C.
I’m pretty sure it’s the first one
