Answer:
9 times
Step-by-step explanation:
Area = length x breadth
area of picture not enlarged = 3 x 5 = 15in²
If length is tripled it becomes , 3 x 3 = 9in
If width is tripled, it becomes , 5 x 3 = 15in
Area of enlarged picture = 9in x 15in = 135in²
amount by which enlarged image is larger = 135in² /15in² = 9
Answer:
15 if b is supposed to the side length, √15 if b is the base which is a square.
Step-by-step explanation:
Rewrite using the formula for the standard form
The answer is y-4x^2 + 12x + 9
The answer would be 14, because 1.75 x 8= 14
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.
</span>
Have a nice day
