The intensity of light that falls on an object is given by the formula I = P/d

In the formula, d is the distance from the light source,

P is the power in lumens, and I is the intensity of light in lumens per square meter.

An object being photographed is 3 meters from a 72-lumen light source.

What is the intensity in lumens per square meter?

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
