Answer:
$116.84 Exactly
Step-by-step explanation:
I would say C because it does not have a 90° angle, but the rest has at least 1 90° angles.
Answer:
[(2 + √3)/4] = 0.9330127
Step-by-step explanation:
We know that
cos (pi/12) ^ 2 =
cos (pi/12)* cos (pi/12) =
[(√6 + √2)/4]*[(√6 + √2)/4] =
(0.9659)*(0.9659) = 0.9330127
[(2 + √3)/4] = 0.9330127
Answer:
B. For any two real numbers, the first is non-negative, the second is negative, and the difference is positive.
Step-by-step explanation:
To answer this question, I'll analyse the mathematical statements one at a time
The analysis is as follows:
∀x -> This means real number x
∀y -> This means real number y
(x ≥ 0) -> Such that real number x is greater than or equal to 0. In other words, x is positive
∧ -> and
(y < 0)-> y is less than 0. In other words, y is negative
So, there are two real numbers: x and y
→ (x – y > 0) -> Their difference is greater than 0. In other words, their difference is positive
When the analysis above is compared to the list of given options; the option that match is B.
Hence, option B answers the question.
