Answer:
There is no angle E in the quadilateral presented in the question. Also, the angles he used are not on opposite side.
Step-by-step explanation:
To classify a quadrilateral is a parallelogram, a quadrilateral with both pairs of opposite sides must be parallel or congruent, that is in a quadrilateral ABCD, angle AB must equal CD and angle AD must equal BC.
Hence, when Felix said quadrilateral ABCD is a parallelogram because of BE = DE. His error was that "there is no angle E in the quadrilateral presented in the question and the angle he used are not on opposite side"
Answer:
The vertex form parabola y = 2( x+4)² -37
Step-by-step explanation:
<u>Step(i):-</u>
Given parabola equation j(x) = 2x² + 8x -5
Let y = 2x² + 8x -5
⇒ y = 2(x² + 2(4x)+(4)²-(4)²) -5
By using (a + b)² = a² +2ab +b²
y = 2(x+4)²- 32 -5
y = 2 ( x-(-4))² -37
<u><em>Step(ii):-</em></u>
The vertex form parabola y = a( x-h)² +k
The vertex form parabola y = 2(x+4)² -37
A triangular prism is composed of 2 triangles and 3 rectangles.
1 triangle has 2 right triangle, for a total of 4 right triangles.
Area of a right triangle = ab/2 = (3.5m * 2m)/2 = 7/2 = 3.5m²
3.5m² x 4 right triangles = 14 m² total area of the triangle bases.
Rectangle: length = 11 m ; width = 4m
Area of a rectangle = L * W = 11m * 4m = 44m²
44m² x 3 rectangles = 132 m² total area of the rectangle faces
<span>Surface area = 132 m² + 14 m² = 146 m²

Answer:
Step-by-step explanation:
There are 4 tens.
There are 48 cards that are not a 10. The probability of drawing 1 of the 48 is
P(~10) = 48/52 which is quite high as you might imagine.
