Radiation machines, used to treat tumors, produce an intensity of radiation that varies inversely as the square of the distance from the machine. at 3 meters, the radiation intensity is 62.5 milliroentgens per hour. what is the intensity at a distance of 2.7 meters? the intensity per hour. (round to the nearest tenth as needed.)

77.2 milliroentgens per hour

Step-by-step explanation:

The first step is to find the constant of proportionality

I ∝ 1/d²

I = k/d²

62.5 = k/(3)²

k = 562.5

The second step is to calculate the intensity at 2.7 meters:

I = 562.5/d²

I = 562.5/(2.7)²

I = 77.2 milliroentgens per hour

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
