Answer:
574.5 A) 52.5 B) 294 C) 341.25 D) 599.5
Step-by-step explanation:
3*104+2.5*105=312+262.5=574.5
A) 0.5*105=52.5
B) 2.8*105=294
C) 3.25*105=341.25
D) 5.5*109=599.5
Answer:
u=2
Step-by-step explanation:
8u-21 = 2u-9
+21 +21
8u= 2u + 12
-2u -2u
6u= 12
divide by 6, u=2 !!
Answer:
...so cos t = cot t can only happen when cos t is 0 or sin t is 1. (But sin t = 1 only happens when cos t = 0, so cos t = 0 is enough.)
arccos(0) is pi/2, plus or minus any multiple of pi.
Step-by-step explanation:
cotθ = cosθ
cosθ/sinθ = cosθ
sinθ = 1
θ = π/2
pi also = to 3.14 etc.
