Answer:
6
Step-by-step explanation:
<u>3x12</u> = <u>36</u>
(4+2) 6
simplify
36/6=6
The value is indeed 6 and there shouldn't be a variable because if there is, then there should be a variable in the question.
No this isn’t a function because it doesn’t pass the vertical line test.
Answer:
$20
Step-by-step explanation:
So since there are 4 three bagels in a dozen, and each three bagels are 5 dollars then you multiply 5 times 4.
You can also find how much it is for 1 bagel by divided 5 dollars by 3 bagels. Multiply that by 12.
Hope this helps! (^-^)
1/(sin(90 + θ)cos(360 - θ)) - tan²(-θ)
Note:
sin(90 + θ) = cosθ Cosine and Sine are complementary.
cos(360 - θ) = cosθ Cosine positive in 4th quadrant.
tan(-θ) = -tanθ Negative angle concept.
1/(sin(90 + θ)cos(360 - θ)) - tan²(-θ) = 1/(cosθcosθ) - (-tanθ)²
= 1/(cos²θ) - tan²θ
= (1/cosθ)² - tan²θ
Note: 1/cosθ = secθ
= (secθ)² - tan²θ
= sec²θ - tan²θ
= 1
Note that 1+ tan²θ = sec²θ is a Trigonometric identity.
That means: sec²θ - tan²θ = 1
Hope this explains it.
