Answer:
<h3>Given</h3>
- g varies jointly with h and j
- g = 4 when h = 1/2, j = 1/3
<h3>To find</h3>
- Value of g when h = 2 and j = 3
<h3>Joint variation:</h3>
- g = khj, where k- coefficient
Use given values of h and j, and find the value of k:
- 4 = k*(1/2)(1/3)
- 4 = (1/6)k
- k = 4*6
- k = 24
The equation is now:
Find the value of g when h is 2 and j is 3:
<u>Correct choice</u> is D
Answer:
sin trigonometry ratio
Step-by-step explanation:
Given
See attachment for triangles
Required
Explain why
From the attached diagram, both triangles are similar triangles because
(1) the second triangle is a dilation of the first triangle by a ratio of 1.5
i.e
(2) They have angle 30 degrees, and have their right angles located at the same point
In the first triangle, the sine of 30 degrees is represented as:
This gives:
In the second triangle:
So:
By comparison:
Hence:
Well, we know the angle θ terminal location, is at -3,2, so the adjacent side is -3 and the opposite side is 2, so it looks like the picture below, therefore
The answer is (2,-2). This is because when you set the x value over the y value, it does not simplify to the same ratio, and all of the others do. Take a look at my work...
Answer:
<u>Step-by-step explanation:</u>
sin is an odd function and cos is an even function.
To convert a sin graph to a cos graph, shift the sin graph units to the right --> C =
