Answer:
18.67 m/s²
Step-by-step explanation:
a = ∆v/ t
a= v - u/t
a = 2.8 - 0 / 0.15
a = 2.8 / 0.15
a = 18.67 m/s²
First distribute 3 to (x-4). that gives you 3x-12. Now your equation is x-2=3x-12. Now you subtract x from 3x. now you're equation is -2=2x-12. then add 12 to the left. You're final answer is 10.
You can eliminate D right away. The sine is NEVER greater than one. That's because the denominator of the fraction is always the hypotenuse.
The definition of the sine is
Sin(x) = Opposite / hypotenuse.
Sin(x) = 10/26 = 5/13 The fraction reduces.
The answer is B
