Answer:
Quadrilateral FSHB∼quadrilateral KTWJ.
Step-by-step explanation:
Given two quadrilaterals we have to prove these two similar.
The two quadrilaterals are similar if the corresponding sides of these are proportional then only the quadrilateral are proportional i.e
∴ 
If the above condition satisfied then the quadrilateral are similar.
Let us find these ratios
All ratios are equal.
Hence, the corresponding sides and angles of these two quadrilaterals are proportional implies that these two are similar i.e quadrilateral FSHB∼quadrilateral KTWJ.
It's 77.472 , but since you probably need too round it will be 77.5
The sketch of the parabola is attached below
We have the focus
The point
The directrix, c at
The steps to find the equation of the parabola are as follows
Step 1
Find the distance between the focus and the point P using Pythagoras. We have two coordinates;
and
.
We need the vertical and horizontal distances to find the hypotenuse (the diagram is shown in the second diagram).
The distance between the focus and point P is given by
Step 2
Find the distance between the point P to the directrix
. It is a vertical distance between y and c, expressed as
Step 3
The equation of parabola is then given as
=
⇒ substituting a, b and c
⇒Rearranging and making
the subject gives

Answer:
42 minutes is the median amount of time
Step-by-step explanation:
The Median is the middle value of data set.
If there is "odd" number of numbers, and there are n numbers, the median is:
(n/2) + 1 th number
If there is "even" number of numbers, and there are n numbers, the median is:
Average of n/2th and (n/2) + 1 th number
Here, we have 5 numbers, so the median would be:
(5/2) + 1 th number
That is
3rd number
But, we need to arrange the numbers from least to greatest. Lets write it:
19, 23, 42, 56, 67
The third number is 42, this is the median
