The to this question is that it is a function
So plug in the 5 for x. it would look like 7(5+4). you do PEMDAS and then looks like 7(9) and 7 multiplied by 9 equals 63.
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
Answer:
y = -3/2x -5
Step-by-step explanation:
We want slope intercept form which is y = mx+b
Y+2=-3/2(x+2)
Distribute
y+2 = -3/2x -3
Subtract 2 from each side
y+2-2 = -3/2x -3-2
y = -3/2x -5
