Answer:
(L, W) ≈ (8.33, 4.17)
Step-by-step explanation:
Substituting for L, we have ...
2(2W) +2W = 25
6W = 25
W = 25/6 ≈ 4.17
L = 25/3 ≈ 8.33
The rounded "exact" solution is ...
(L, W) = (8.33, 4.17)
Answer:
Therefore it will take s for the object to reach the ground.
Step-by-step explanation:
Given function is
H(t) = -64 t²+169.
where H is height in feet, and t is time in second.
When the object touches the ground, the height of the object will be zero.
i.e H(t) = 0.
Therefore
H(t) = 0
⇒ -64 t²+169=0
⇒ -64 t²= -169
[ square root both sides]
Time can not be negative.
Therefore
Therefore it will take s for the object to reach the ground.
