For each alphabet, you're giving it a value. So, since A is the first letter of the alphabet, its value would be 1. Since B is the second letter of the alphabet, its value would be 2, and so on.

What you have to do for A is to find the total number by adding each value from your name. In example, if your name was Bob, it would be 19 (2 + 15 + 2)

For B you just have to write two 3-letter words that would make up 20. An example can be DIG (4 + 9 + 7 = 20)

In part A, if a's value is 1 then b is 2 and so on so the first letter of your name will have a number, and for part b you tale 3 letters that make up a word and the number after also equals 20.

Suppose the sound wave has the form y=7cos(3x-pi/6) for x in the interval [pi/6 , 7pi/18]. Express x as a function of y, and sta
Vesnalui [34]

Answer:

x = ⅓ acos(y/7) + π/18, [-7, 7/2]

Step-by-step explanation:

y = 7 cos(3x − π/6)

Solving for x:

y/7 = cos(3x − π/6)

acos(y/7) = 3x − π/6

acos(y/7) + π/6 = 3x

x = ⅓ acos(y/7) + π/18

The domain of x is the same as the range of y.

When x = π/6:

y = 7 cos(3π/6 − π/6)

y = 7 cos(π/3)

y = 7/2

When x = 7π/18:

y = 7 cos(21π/18 − π/6)

y = 7 cos(π)

y = -7

So the domain of x as a function of y is [-7, 7/2].

The formula P=2(l + w)relates the perimeter P, in decimeters, with the length and width of a rectangle.
Degger [83]

Answer:

3. w=P/2-L

Step-by-step explanation:

<u>Given formula:</u>

  • P=2(l + w)

<u>Solving for w:</u>

  • P=2(l + w)
  • P/2 = 2(l + w)/2
  • P/2 = l + w
  • P/2 - l = l + w - l
  • P/2 - l = w
  • w = P/2 - l

<u>Correct answer choice is:</u>

  • 3. w=P/2-L
