Plug in 1.5 for x, to start off. It is then simplified to : 3*(1.5)* y - 5y
Then plug in -3 for y, it's then simplified to : 3*(1.5)* -3 - 5 * (-3)
First, multiply 1.5 times 3, and that will get you 4.5. The multiply 4.5 with -3, and that will get you -13.5. Moving on, subtract -13.5 from the 5 that is being multiplied to -3, which is -15. In conclusion, -13.5 subtracted from -15 would be -28.5. Hope this helps!
Answer:
The intensity becomes one fourth when the distance is doubled.
Step-by-step explanation:
The statement is
Intensity of light varies inversly as the square of the distance
So we get
Now for distance 12in let the intensity be
So we get
...(1)
For distance 24in, let the intensity be
We get
....(2)
Dividing (1) by (2) we get
Hence the intensity becomes one fourth
