Place a dot on 7 and do < underlined
Answer: k = 55 degrees
Step-by-step explanation:
to find J, subtract 122 from 180, you get 58. The total number of degrees is 180. Since L is given as 67, and 67+58=125. Simply subtract 125 from 180 which is 55 degrees
There's a site called m.a.t.h.w.a.y, and you can type in those functions in order to get the graph ;)
Step-by-step explanation:
The statement is 3 multiplied by 2/3. Here, the first no of 3 and the other one is 2/3.
It can be written as follows :
3 is present at the numerator as well as the denominator. It will cancel out.
So,
=2
So, 3 multiplied by 2/3 equals 2.
Answer:
The jetski is 2.28 dB loud when the person is 41 feet away.
Step-by-step explanation:
Loudness (L) ∝ 1 / Distance² (d²)
Introduce a constant 'K'
L = K (1/d²)
L = K/d²
K = Ld²
Find the K from a previously known information: If a person 8 feet from a jetski hears 60 decibels loud
∴ d = 8 ft , L = 60 db
K = 60(8²) = <em>3840</em>
How loud is the jetski when the person is 41 feet away?
Distance is now 41 ft
since: L = K/d²
∴ L = 3840 / 41²
L = 3840 / 1681
L = 2.28 db
