Answer: The correct option is D.
Explanation:
It is given that the triangle ABC is an isosceles triangle. It is also given that the line BD is the median of triangle ABC.
Since DB is median it means point D divides the line AC in two equal parts.
The The median of an isosceles triangle is always a perpendicular bisector of the opposite side. Since the median is perpendicular on side AC, therefore the sides AB and CB are equal.
In triangle ABD and CBD,
.... (Isosceles triangle)
.... (D is midpoint of AC)
.... (Common Side)
Therefore option D is correct.

Answer:
(a) (5π -11.6) ft²
Step-by-step explanation:
The shaded area is the area of 1/5 of the circle less the area of the triangle with base 5.8 ft and height 4 ft.
shaded area = 1/5(π(5 ft)²) -(1/2)(5.8 ft)(4 ft)
shaded area = (5π -11.6) ft²
8 hours 2 minutes. if you add 8hours to 10:13 you get 6:13 then just add 2 minutes and you will have 6:15 p.m
We have been given graph of a sinusoidal function. We are asked to write function formula for our given graph.
We know that and . We can see that our given function is starting at origin, so our graph is sine function.
We know that general form of sine is , where,
A = Amplitude,
Period:
C = Horizontal shift,
D = Vertical shift.
We have been given that function has no horizontal shift, so the value of C is 0.
We can also see that midline of our function is x-axis, so there is no vertical shift as well that is .
We can see that function goes up to 1 from midline and goes down to from midline, so amplitude of function is 1 that is .
We can see that period of our given function is because it completes one cycle from to
We can see that our function is reflected about x-axis, so our function will be .
Therefore, our required function is .
