Answer: compass and straightedge or ruler
Perpendicular bisector of a line segment
Geometry construction using a compass and straightedge
compass and straightedge or ruler
Step-by-step explanation:
Answer:
80°
Step-by-step explanation:
diameters intersect at centre so measure of arc is the angle at the centre.
so x=80°
4. A graph shows the solutions to be
x = -3/2, -1, 0
The root at -1 has multiplicity 2. That is, the factoring is
x(2x+3)(x +1)² = 0
5. A graph shows the real roots to be
x = -1, 2
Dividing these from the polynomial gives the quadratic
x^2 +3
which has roots
x = ±i√3
The factorization is
(x +1)(x -2)(x² +3) = 0
and the solutions are
x = -1, 2, -(√3)i, (√3)i
The answer is B. If there ever a question similar to this, just put the equation in graphs calculator and see what the graph look like. I hope this is helpful.
