Perimeter = 2w + 2l = 2(12) + 2(10) = 44
Answer:
The models are different.
Step-by-step explanation:
Yelania and Audrey took two cards which are 4,-6 and 4,6 respectively.
They do not lie on the same points as the sum of Yelania's cards=4-6=-2 and the sum of Audrey's cards=4+6=10.
Both -2 and 10 lie differently on the number line.
Therefore, the models are different from each other.
Answer:
factor of 6 and 5
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The graph shows it clearly.
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.
