A 40­acre field produces 600 bushels of wheat. At the same rate, how many bushels will a 75­acre field produce? A)   5 bushels B
wariber [46]
Since 40 acres of land produces 600 bushels
so the bushels produced by 1 acres of land is 600/40=15
So bushels produced by 75 actes of land = 75×15=1125 bushels

Express the illuminance on the floor as a composite function of t for 0 < t < 8.
GrogVix [38]
The formula for illuminance is given by
E = I / d^2
This formula only holds true for one-dimensional illuminance
The problem asks for the illuminance across the floor. We need to use two variables, x and y.
From Pythagorean Theorem
d^2 = x^2 + y^2
and from Trigonometry
x = d cos t
y = d sin t

The function for the illuminance can be represented by the composite function
E = I cos² t / x²
and
E = I sin² t / y²

The boundary of these functions is:
<span>0 < t < 8
So, the value of t must be in radians and not in degrees</span>
