Answer:
B. W,V,Z
Step-by-step explanation:
Collinear points are two more points in the same plane that lie in a straight line.
From the diagram, Z is the intersection of the two diagonals of quadrilateral VXWY.
The points V, Z and W lie along the same diagonal, hence they are collinear.
The point y, Z, and X also lie along the same diagonal, these are also collinear.
The correct choice is B
Solve for x:
x^2 + 4 x + 25 = 0 I ssume that's the notation.
Subtract 25 from both sides:
x^2 + 4 x = -25
Add 4 to both sides:
x^2 + 4 x + 4 = -21
Write the left hand side as a square:
(x + 2)^2 = -21
Take the square root of both sides:
x + 2 = i sqrt(21) or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
x = i sqrt(21) - 2 or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
Answer: x = i sqrt(21) - 2 or x = -i sqrt(21) - 2
Find s8 for the following geometric sequence: 3, –6, 12,
–24. = –255
Answer:
Circ=37.704, Area= 112.112
Step-by-step explanation:
Circumference= pi *Diameter
Taking pi=3.142, Diameter=12
Circ=3.142*12=37.704
Area= pi * r^2
Area= 3.142*6*6=112.112
