Answer:
The possible length is greater than 29 meters.
Step-by-step explanation:
If the length is x then the width is x - 2 m.
So the perimeter is 2x + 2(x - 2) = 4x - 4 m.
4x - 4 > 112
4x > 116
x > 29 m.
0.9 x 30 = 27

Answer:
The approximate length of the pendulum is 46.08 ft
Step-by-step explanation:
The time (t) of pendulum oscillation is given as;
where;
L is the length of the pendulum
g is acceleration due to gravity = 9.8 m/s² = 32.15 ft/s²
t is the time given as 2.4 π seconds
From the equation above, make L the subject of the formula;
Therefore, the approximate length of the pendulum is 46.29 ft
The closest option is 46.08 ft
Y=-2x+4. is what it simplifies too. there is not enough info to solve
