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>

Answer:
I believe it is 2s
Step-by-step explanation:
a variable is a symbol which functions as a placeholder, so in this case, the placeholder is "s"
Answer:
Hello your question is incomplete below is the complete question
option B is correct
f(x) = 1 if x ≤ 0
-2 if x > 0
Step-by-step explanation:
The Rule of the piece-wise-defined function is :
from the given figure attached it can be seen that as : x ≤ 0 , y = 1
while for x > 0 , y = -2
therefore option B is correct
f(x) = 1 if x ≤ 0
-2 if x > 0
Answer:
x=110
Step-by-step explanation:
Since the sum of the interior angles of a trapazoid is 360, all you have to do is add the angles given and subtract that by 360, which gets you 110.
