Sample set d

Use a calculator to perform each division.

328 ÷ 8 size 12{"328" div 8} {}

Type 328
Press ÷
Type 8
Press =

The display now reads 41.

53 , 136 ÷ 82 size 12{"53","136" div "82"} {}

Type 53136
Press ÷
Type 82
Press =

The display now reads 648.

730 , 019 , 001 ÷ 326 size 12{"730","019","001" div "326"} {}

We first try to enter 730,019,001 but find that we can only enter 73001900. If our calculator has only an eight-digit display (as most nonscientific calculators do), we will be unable to use the calculator to perform this division.

3727 ÷ 49 size 12{"3727" div "49"} {}

Type 3727
Press ÷
Type 49
Press =

The display now reads 76.061224.

This number is an example of a decimal number (see [link] ). When a decimal number results in a calculator division, we can conclude that the division produces a remainder.

21 , 996 , 385 , 287 ÷ 53 size 12{"21","996","385","287" div "53"} {}

Since the dividend has more than eight digits, this division cannot be performed on most nonscientific calculators. On others, the answer is 415,026,137.4

4, 558 ÷ 67 size 12{4,"558" div "57"} {}

This division results in 68.02985075, a decimal number, and therefore, we cannot, at this time, find the value of the remainder. Later, we will discuss decimal numbers.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
