9/20 I think is the rational number
Answer:
B.
Step-by-step explanation:
To answer, lets look at the definitions of each name.
First, a quadrilateral. A quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices, so it basically just has 4 sides, which this figure has, so this figure is a quadrilateral.
Next, a parallelogram. A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. So as long as a figure has 4 sides and at least 2 opposite sides that will never collide, it is a parallelogram. Because our figure has 4 sides and each pair of opposite sides is parallel, this figure is a parallelogram.
Last, a rectangle. A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. So, as long as there are 4 sides and 4 right angles, and 2 of the opposite sides are longer than the other set of opposite sides, it is a rectangle, and this figure fills all the requirements.
So, since the figure is a quadrilateral, a parallelogram, and a rectangle, the answer is B.
Hope this helps :)
Answer:
Equation of tangent is
Step-by-step explanation:
Given:
Equation of curve, y = sec x
Passing through point =
We need to find Equation of tangent to the given curve and at the given point.
First we find the slope of the tangent by differentiating the given curve.
As we know that slope of the tangent, m =
So, consider
y = sec x
Now we find value of slope at given point,
put x = in above derivate
we get
Now using Slope point form, we have
Equation of tangent
Therefore, Equation of tangent is
