Use the “equal temper” scale with the 12 semitones A, A#, B, C, C#, D, D#, E, F, F#, G, and G# and the frequency of A is 440 Hz. On a piano keyboard, the distance between two white keys that are side by side is a whole note if there is a black key between them, and it is a semitone if there is no black key between them. A black key (such as the one between C and D) is called a sharp. The black key between C and D is denoted by C#. Remember that the change in frequency P( f ) between any two consecutive semitones is 100 cents.
A whole tone is a frequency ratio of 10:9. That is,

- i circled the correct answer and i did most of the question but i cant figure out how to add both residues to get the correct answer could you please show me how to do itarrow_forwardQuestion 3 Starting at the point (0, −2,0), I walk up the hill z = 4-x² — y². The projection of my path on the xy plane is the line y = 2x-2. (a) At what point on my path is my altitude (the z-value) the greatest? (b) What is the slope m of my path (taking the z-axis to be vertical) when I am at the point (1, 0, 3)? [Hint: Parametrize my path (take x to be t).]arrow_forwardI circled the correct, could you explain using stokearrow_forward
- Use Euler's method to numerically integrate dy dx -2x+12x² - 20x +8.5 from x=0 to x=4 with a step size of 0.5. The initial condition at x=0 is y=1. Recall that the exact solution is given by y = -0.5x+4x³- 10x² + 8.5x+1arrow_forwardFind an equation of the line tangent to the graph of f(x) = (5x-9)(x+4) at (2,6).arrow_forwardFind the point on the graph of the given function at which the slope of the tangent line is the given slope. 2 f(x)=8x²+4x-7; slope of the tangent line = -3arrow_forward
