Answer:
coordinates of B is ( 4,5)
Step-by-step explanation:
If there two points (x1,y1) and (x2,y2) on a plane then coordinates of mid point is given by
m = (x1+x2)/2 , (y1+y2)/2
Given
m = (-1,1)
A= (-6, -3)
we have to point b
let point b be (x,y)
Then m (-1,1) is given by (-6+x)/2 , (-3+y)/2
(-6+x)/2 = -1
-6 + x = 2*-1 = -2
x = -2+6 = 4
also
(-3+y)/2 = 1
=> -3 + y = 2
=> y = 2 + 3 = 5
Thus , coordinates of B is ( 4,5) answer
Answer:
The function will be: f(n) = 2n
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between consecutive terms is same
The sequence according to given information is:
2,4,6...
Here
a_1 = 2
a_2 = 4
a_3 = 6
the common difference will be:

The arithmetic sequence is given by:

Putting the values

Hence,
The function will be: f(n) = 2n
Answer:
C
Step-by-step explanation:
The distance YZ is sqrt(34^2-30^2)=16
Answer:
Statements A and B are both true.
If we have a 13-gon, n=13
Then
Sum-of-interior-angles-n-gon+= (13-2) x 180
Sum-of-interior-angles-n-gon+=(11) x 180
Sum-of-interior-angles-n-gon+= (11) x 180
Sum-of-interior-angles-n-gon+= 1980
Hope this helps!
