Answer: None of the above
Step-by-step explanation:
Since the quadrilateral is inscribed inside the circle, where the four vertices are on the circle itself, this means that the opposite angles add to 180 degrees.
Angle I and Angle D are opposite angles. They add to 180 degrees
(angle I) + (angle D) = 180
(45 degrees) + (angle D) = 180
(angle D) + 45 = 180
(angle D) + 45 - 45 = 180 - 45 ... subtract 45 from both sides
angle D = 135
The measure of angle D is 135 degrees
The frequency of the periodic function is given by: 0.0796.
<h3>What are the period and the frequency of a function?</h3>
- The period of a function is given by the <u>distance between it's repetitions</u>.
- The frequency of a function is found <u>dividing one by the period</u>.
From the graph, we have that the period is of 4pi hours, hence the frequency is:
f = 1/4pi = 0.0796.

Answer:
D and E
Step-by-step explanation:
x² = 15 ( take square root of both sides )
x = ± ![\sqrt{15}](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D)
that is
x =
, x = - ![\sqrt{15}](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D)
The ratio of interest can be found for collinear points by considering only one of the coordinates. Let's look at the x-coordinates.
(Tx -Mx)/(Dx -Mx) = (1-(-3))/(9-(-3)) = 4/12 = 1/3
Then the ratio of interest is MT:MD = 1:3.
