For all of the triangles you have to use Sin, Cosin, or Tangent. Sin= opposite/hypotenuse, Cosin=adjacent/hypotenuse, and Tangent= opposite/adjacent.
Question 2-
You have the hypotenuse and you are trying to find the adjacent. Cos(35)=x/51
Multiply the 51 over and now you have 51Cos(35)=x. x=41.77m
Question 3-
Tan(30)= x/24. 24Tan(30)=x. x= 13.856m
Question 4-
Sin(70)=x/18. 18Sin(70)=x. x=16.9 m
Question 5-
Cos(60)= x/30. 30Cos(60)=x. x=15m
Question 6-
Tan(55)=x/6. 6Tan(55)=x. x= 8.568m
Answer:
a = 132 m/s^2
Explanation:
f(t) = t^4 − 2t^3 − 6t^2 + 9t
v = f'(t) = 4t^3 - 6t^2 - 12t + 9
a = f''(t) = 12t^2 - 12t -12
Substitute t = 4 seconds into the equation for a:
a = 12(16) -12(4) -12 = 132 m/s^2
Answer:
720 feet
Explanation:
10 x 6 = 60 seconds which is one minute
so
120 x 6 = 720 feet
