Answer: 1+(-3)
Because you round the numbers, anything below 5 is rounded to 0 and anything 5 or above is rounded up. like 1.2 is 1, and 5.7 is 6.
When angles are restricted to real numbers, Bernhard is correct. The sine function has a range of -1 to 1 (inclusive).
_____
When angles are allowed to be complex numbers, the magnitude of the sine of an angle may exceed 1. In this realm, both Henrik and Bernhard are incorrect.
2cos^2 x + 3sin x = 0
2(1 - sin^2 x) + 3sin x = 0
2 - 2sin^2 x + 3sin x = 0
2sin^2 x - 3sin x - 2 = 0
Let sin x = m, then
2m^2 - 3m - 2 = 0
2m^2 + m - 4m - 2 = 0
m(2m + 1) - 2(2m + 1) = 0
(m - 2)(2m + 1) = 0
m = 2 or m = -1/2
Now, sin x = -1/2
Therefore, x = 1/6(12nπ - π) and 1/6(12nπ + 7π)
Answer:
330
Step-by-step explanation:
The prism is a triangular prism
9 * (12 + 5 + 13) + (2 * 30)= 330
30 being the base area
<span>△RST is a right triangle because RS¯¯ is perpendicular to RT¯¯ .</span>
