W^2+5w-66=0
Factor
(w+11)(w-6)=0
w+11=0
w=-11 (not possible - cant have negative length
w-6=0
w=6
L(6)=66
L=11
Width = 6
Length = 11
Answer:
94 or 95
Step-by-step explanation:
91 + 95 + 87 + 83 = 356
356/4 =89
average so far is 89
356 + 94 = 450
450/5 = 90
356 + 95 = 451
451/5= 90.2
I am pretty sure the answer is A because the graph is a cubic function
Since the distance from the two known coordinates are known, you can find the slope of the line (for lack of a better word) to work backwards. there is a +5 unit gap between -21 and -16, so the next number would be -26. So, without havint to do any more work, the answer is B.
Hello.
The further away from the speakers you are t<span>he less intense the sound will be.
</span>
<span> If sound intensity varies inversely with the square of the distance, you can represent this as: </span>
<span>I = 1/d^2 </span>
<span>If you double the distance: </span>
<span>I = 1/(2d)^2 </span>
<span>I = 1/4d^2 </span>
<span>I = 1/4d^2 </span>
<span>so by doubling the distance, you have 1/4th the intensity.

Have a nice day
