Shown in the figure, all the measurements of each sides is different, so it is only a quadrilateral. Square has four equal sides and angles, rhombus has only four equal sides, and a parallelogram whose opposite sides are parallel.
<u>Answer:</u>
<em>Picture 1 (Rhombus)</em>
<em>Picture </em><em>2</em><em> </em><em>(Square)</em>
<em>Picture 3 (Parallelogram)</em>
<em>Picture 4 (Quadrilateral)</em>

Answer:
Options (B) and (E)
Step-by-step explanation:
Area of ΔABC =
=
= 42 in²
Area of trapezoid ADEC =
[Here, and
are the parallel sides and 'h' is the height of the isosceles trapezoid given]
=
= 96 in²
Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC
= 42 + 96
= 138 in²
Therefore, Options (B) and (E) are the correct options.
Answer:
(27.55, 7.22), (-11.3, 3.21).
Step-by-step explanation:
When is the tangent to the curve horizontal?
The tangent curve is horizontal when the derivative is zero.
The derivative is:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that
, given by the following formulas:
In this question:
So
Then
So
Enter your answers as a comma-separated list of ordered pairs.
We found values of t, now we have to replace in the equations for x and y.
t = 3.35
The first point is (27.55, 7.22)
t = -2.685
The second point is (-11.3, 3.21).
