Answer:
It's Angle ABC because an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle
The slope is 1.3. The whole equation is y=1.3x+4.9
Since there is a common difference of one, this is an arithmetic sequence of the form a(n)=a+d(n-1) which in this case is:
a(n)=15+1(n-1)
All arithmetic sequences have a sum which is equal to the average of the first and last terms time the number of terms, mathematically:
s(n)=(2an+dn^2-dn)/2 (that is just the result of ((a+a+d(n-1))(n/2)) )
Since a=15 and d=1 this becomes:
s(n)=(30n+n^2-n)/2
s(n)=(n^2+29n)/2 so
s(10)=(100+290)/2
s(10)=195 logs
Answer:
68.
Step-by-step explanation:
The common difference d = -19 - (-22) = 3
So the 31st term =
a31 = -22 + (31-1)3
= -22 + 90
= 90 - 22
= 68.
Answer:
A = 3,-1
B = 2, 4
C = -3, 0
D = 1,-1
Step-by-step explanation:
First, you should know that the first number is the x axis, and the second number is the y axis. You ALWAYS find the x axis first. Next, you start from the origin point, 0. 0 is where the two lines meet. Starting from 0, you move the point three spaces to the right, and one down to get to point A. So, the coordinate would be 3,-1. For point B, you would move two points to the right, and 4 down. That brings you to 2,4 the coordinates for point B. Do the same things for C and D. Go three spaces left, and stay there. That would be -3,0. For D, go right 1, and one down. Remember UP and RIGHT = Positive, DOWN and LEFT = Negative. Hope this helped!
