Answer:
1012
Step-by-step explanation:
Given:
pitch 'p' = 460 vibrations per second
wavelength 'w'= 2.2m
'k' represent constant of variation
'k' can be determined by taking the product of pitch and wavelength
k= p.w
k= 460 x 2.2
k= 1012
Therefore,
the constant of variation is 1012
The Answer is: B.29
Because 6.5x4= 26 since it’s a triangle that is divided by 2 to get 13 once you finish the top half the bottom is a square 4x4=16 so 16+13=29
Slope is found by doing this formula:
So, if we graph the points. We will see that the y value changes
That's our rise.
Then, for the run
The slope would look like this
Our fraction:
That's our slope!
Answer: option a. 5.46
Explanation:
The side lengths of the golden rectangle are in the proportion:
1
--------------------
golden number
The golden numbrer is:
1 + √5
-----------
2
So, the ratio is:
1
--------------
1 + √5
---------
2
And, using the properties of the division of fractions, that is equivalent to:
2
-------------
1 + √5
Since you have the given side t = 9, you can set the proportion, to find the unknown lenght, s:
2 s
--------- = ---------
1 + √5 t
2 s
--------- = ---------
1 + √5 9
And you can solve for s:
s = 9 * 2 / (1 + √5) ≈ 18 / (1 + 2.236) = 18 / (3.236) ≈ 5.56.
Which is the option a. 5.56
