Answer:
Step-by-step explanation:
H=7+30t-16t²
20=-16t²+30t+7
0=-16t²+30t-13
T=(-30±√(900-4(16)13))/-32
T=0.68 s or T=1.2 s
Answer:
Option (2)
Step-by-step explanation:
Let the savings of Joel = $y
And the savings of Matt = $x
They jointly save at least $50 to buy a special present.
Therefore, equation for this condition will be,
x + y ≥ 50 --------(1)
Joel saves twice as much as Matt.
Equation for this condition will be,
y = 2x ------ (2)
By substituting the value of 'y' in the equation,
x + 2x ≥ 50
Therefore, Option (2) will be the answer.
