Step-by-step explanation:
it's 6
as,
-12 × 6 = -72

Answer:
B
Step-by-step explanation:
To be a function every input must have exactly one output. There are two input values with 2, therefore this makes it not a function.
They are complementary because if you were to put them on top of one another they'd line up. (same degree measurement)
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.

Answer:
D. Reflexive Property
Explanation:
In order to prove that segment AB is congruent to segment ED, you need to first prove that triangle ACB is congruent to triangle ECD.
Reflexive property is not used as a reason to prove since no angles or segments are shared.
Hope this helps!!
Please give me brainliest if it is correct :)
