Answer:
option B is true.
Step-by-step explanation:
We are given that two functions
f(x)= and g(x)=sin x and a line x =
We have to find the area of the region bounded in the first quadrant by x= and two functions
We know that the area bounded by two functions
=Integration of region(Upper curve- lower curve)
Therefore, function of sec square x is upper curve and function of sin x is lower function
Therefore, limit of x changing from 0 to
Hence, the area of the region bounded in the first quadrant and two functions is given by
Therefore, option B is true.
EF and BC in the trapezoid below are parallel. if ED=35, BC=63, and DC=28
Find the length of BD if EF = 45. Not all figures are rendered to scale.
A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.
The base angles and the diagonals of an isosceles trapezoid are equal. The intersection point of the diagonals is collinear to the midpoints of the two opposite sides. Opposite sides of an isosceles trapezoid are of the same length or congruent to each other.
