Answer:
11
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
g(x) = 3x +2
g(3) = 3·3 +2 = 9 +2
g(3) = 11
S must equal 1, because without the variable, 55=55<span />
Answer:
Option A
Step-by-step explanation:
we start with 12 red marbles out of 25 marbles, that's the probability for the first.
in the second step we have one red marble less, wich also means one marble less overall
and so on
can be reduced by 1320 (step by step) to
Answer: 1.4 m/s
Explanation: the acceleration equation is a = change in velocity/change in time.
Plug the values in and you get 5.6/4
Divide and get 1.4 m/s
Answer:
Step-by-step explanation:
The wind speed can be found using the Law of Cosines. It will be the unknown side of a triangle with sides 6 and 5 and included angle 30°.
s^2 = 6^2 +5^2 -2·6·5·cos(30°) ≈ 9.038476
s ≈ √9.038476 ≈ 3.0064 . . . . m/s
The direction of the wind can be found from the Law of Sines, which tells us the relationship of the internal angle A to velocity vector a is ...
sin(A)/a = sin(30°)/3.0064
A = arcsin(5/3.0064·sin(30°) ≈ 56.26°
To find the desired angle, we must add 180° to this value.
The wind is blowing 3.0 m/s in direction 236.3°.
