Step-by-step explanation:
remember, tan = sin/cos.
of course, one solution is x = 0. sin(0) = 0, tan(0)=0).
for the general solution we look at x <> 0.
3×sin(x) = 2×tan(x) = 2×sin(x)/cos(x)
3 = 2/cos(x)
3×cos(x) = 2
cos(x) = 2/3
x = 48.1896851...°
Answer:
2500 kg
Step-by-step explanation:
Given:
• Force produced by the truck = F = 15,000 Newtons Acceleration of the truck = a = 6 m/s²
To find:
Mass of the truck if force is 15000 newtons and acceleration is 6 m/s²
Formula:
Force = Mass Acceleration
Substituting the above values:
15000N Mass×6
Mass = 15,000/6
Mass = 2500 kg
1/2 = 0.5
Proof:
1/4 + 1/4 = 2/4 = 1/2 = 0.25 + 0.25 = 0.50
