Answer:
(a) 
(b) L reaches its maximum value when θ = 0 because cos²(0) = 1
Step-by-step explanation:
Lambert's Law is given by:
(1)
(a) We can rewrite the above equation in terms of sine function using the following trigonometric identity:
(2)
By entering equation (2) into equation (1) we have the equation in terms of the sine function:
(b) When θ = 0, we have:
We know that cos(θ) is a trigonometric function, between 1 and -1 and reaches its maximun values at nπ, when n = 0,1,2,3...
Hence, L reaches its maximum value when θ = 0 because cos²(0) = 1.

Add $9.40 two times what ever you get multiply that 15 and there’s your answer
The answer is 46 when its rounded off
Answer:
(-4,1)
Step-by-step explanation:
First, subtract 1-5. (When you move left or down you subtract. When you move right or up you add.) Left and right affect the x-axis
Second, subtract 4-3. Up and down Affect the y-axis
It would look like this:
(1,4)
=(1-5,4-3)
=(-4,1)
Answer:
P(marks ≥ 20) = 0.4
Step-by-step explanation:
Marks gotten by the 5 students are;
15, 14, 20, 17, 25
Marks more than or equal to 20 are 2 in number namely 20 and 25.
Thus, probability of getting marks more than or equal to 20 is;
P(marks ≥ 20) = 2/5
P(marks ≥ 20) = 0.4
