I got the answer as to be C
Given two points:
A(x₁,y₁) and B(x₂,y₂) the midpoint would be:
M((x₁+x₂)/2 , (y₁+y₂)/2)
In this case:_
A(-2,6) and B(4,-2); the midpoint would be:
M((-2+4)/2 , (6-2)/2)=(1,2)
Answer: the midpoint of AB is (1,2)
Answer:
y= 2x-1
Step-by-step explanation:
is this what you are asking for?
The value of expression when n = 3 is 22
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
We have to find the value of expression when n = 3
<em><u>Substitute n = 3 in given expression</u></em>
Thus the value of expression when n = 3 is 22
Answer: perimeter = 62
Step-by-step explanation:
To determine the length of the unknown sides of the triangle, we would apply the sine rule which is expressed as
a/SinA = b/SinB = c/SinC
Therefore
AB/Sin 40 = 19.5/Sin 49
ABSin49 = 19.5Sin40 = 19.5 × 0.64
0.755AB = 12.48
AB = 12.48/0.755
AB = 16.5
The sum of the angles in a triangle is 180°. Therefore,
A = 180 - (40 + 49) = 91°
BC/Sin 91 = 19.5/Sin 49
BCSin49 = 19.5Sin91 = 19.5 × 0.9998
0.755BC = 19.5
BC = 19.5/0.755
BC = 25.8
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = a + b + c
Where
a, b and c represents the length of each side of the triangle.
Perimeter of triangle = 25.8 + 16.5 + 19.5 = 62
