12. Both sides of the equation are equal and if 18 is half of 36 then 6×2 will give you the value of X
Answer:
The equation of the new function is y=5/3x+4
Step-by-step explanation:
y=5/3x
Shifted up (+) 4 units:
y=5/3x+4
Should take 8 minutes. I'm not totally sure; Pretty sure somebody else will get this right if I'm not.
Answer:
732.21 m
Step-by-step explanation:
Given the time taken by cadet to cross an obstacle and swing back to where he started = 5.5 seconds
The formula for a complete oscillation(to and fro) period is
<h2>T = 2π * √(L/g)</h2>
where:
<em>T is the period of oscillations</em><em> - time that it takes for the pendulum to complete one full back-and-forth movement.</em>
<em />
<em>L is the length of the pendulum </em>
<em />
<em>g is the acceleration of gravity, which</em><em> is equal to 9.81 m/s^2 </em>
5.5 = 2 π √(L / 9.81)
5.5/2π = √(L / 9.81)
8.64 = √L / 9.81
8.64 ² = L / 9.81
74.64 = L / 9.81
L = 74.64 * 9.81
L = 732.21 m
