Answer:
This is a geometric sequence with a common ratio of -4
Step-by-step explanation:
Take the second term and divide by the first term
-4/1 = -4
Take the third term and divide by the second term
16/-4 = -4
Take the fourth term and divide by the third
-64/16 = -4
This is a geometric sequence with a common ratio of -4
10. How I would solve it, is I would convert them into decimals so it is 7.5/.75.
Answer:
The value of x is 
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of arc DF
we know that
The inscribed angle measures half that of the arc comprising
so

we have

substitute

step 2
Find the measure of x
we know that
---> is a semi circle
we have

substitute

Answer:
student G is in the band
and student B plays the piano and is in the band
B is in the overlap of the two circles which means they fall into both categories
Hope this helped
I messed up before and did students A and B but I fixed it, so sorry that's my bad.
