Answer:
A. They're not simalier because two pairs of corresponding angles in the two trapezoids are congurant
Answer:
146°
Step-by-step explanation:
The measure of the arc EF is equal to the angle subtended at the centre.
That is EF = 146°
Step-by-step explanation:
given that
first term (a1) = 100
common ratio = 1/ 2
the series in Geometric Progression
the first five terms are
a1 = 100
a2 = 100/2 = 50
a3 = 50/ 2 = 25
a4 = 25/ 2 = 12.5
a5 = 6.25
Answer:
Step-by-step explanation:
A quadrilateral is a parallelogram when opposite sides are parallel. This will be the case when ...
- one pair of opposite sides are parallel and the same length (choice B)
- each pair of opposite sides is the same length (choice E)
An isosceles trapezoid has one pair of parallel sides and the other pair of opposite sides the same length, so that is not sufficient to describe a parallelogram. (Choices A and C describe this condition.)
A line segment is always congruent to itself, so that fact establishes nothing about a parallelogram. (choice D)
_____
<em>Comment on opposite sides equal</em>
Choice E can also describe an hourglass-shaped figure. We assume here that the quadrilateral is convex, with no sides crossing each other.
The translation of a function f(x) can be described as:
f(x)->f(x-h)+k
when the functions has been translated h units to the right, and k units up.
Compare with
sqrt(x)->sqrt(x-1)+0
we see that h=1, k=0.
Thus it is a horizontal translation of 1 unit to the right. (zero unit up).
