A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following frequencies: C - 262 Hz E - 330 Hz G - 392 Hz Determine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. (Due to rounding the ratio will be approximate.) How many E waves will fit in the length of four C waves? a. 2 b. 3 c. 4 d. 5 Please select the best answer from the choices provided A B C D

true

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
