Answer:
cos(2u) = 1 - 2
(32°) = 1 - (2
0.281 ) = 1 - 0.5616 = 0.4384
Hence the correct option is E.) 0.4384
Step-by-step explanation:
i) 2u = 64°
ii) u = 32°
iii) sin(32°) = 0.53
iv)
(32°) =
= 0.2808
v) cos(2u) = 1 - 2
(32°) = 1 - (2
0.2808 ) = 1 - 0.5616 = 0.4384
Hence the correct option is E.) 0.4384
Answer:
176 cm^3
Step-by-step explanation:
The volume of prism is given by:
V = w * h * l = width * height * length
V1 = 2 * 8 * 2 = 32 cm^3
V2 = 3 * 6 * 8 = 144 cm^3
V_t = V1 + V2 = 32 + 144 = 176 cm^3
Did you mean 2.6(3)? If so you would do 2.6 times 3 which is 7.8
