Answer:
(1) Parallelogram A parallelogram is a quadrilateral with two
sets of parallel sides. The opposite or facing sides of a
parallelogram are of equal length, and the opposite angles of a
(2) Square
A square is a regular quadrilateral. This means that is has four
equal sides and four equal angles.
(3) Rhombus A rhombus is a quadrilateral whose four sides all have the same
length. Opposite angles of a rhombus have equal measure. The two
diagonals of a rhombus are perpendicular.
(4) Rectangle
A rectangle normally refers to a quadrilateral with four right
angles.
Parallelogram
Step-by-step explanation:
Known facts:
A line shaft rotating at 250 rpm, a grinder shaft that turns at 1200 rpm diameter of grinder pulley is 5 inches.
1. Proportion equation
350/1200 = 5/x
2. Cross multiply
1200*5=250*x
x=(1200*5)/250 = (24*50*5)/(5*50) = 24
The big wheel diameter is 24 inches

Step-by-step explanation:
If
τ
1
and
τ

are two typologies on non-empty set
X
, then ………………. is topological space.
If you find the discriminant it will tell you the number and types of roots. The discriminant is the value b^2 -4ac.
a = 1
b = 1
c = 1
1^2 - 4*1*1
1-4 = -3
Since this is a negative number there will be 2 complex roots.
