Answer:
The equation is,
Step-by-step explanation:
According to the question, the equation is cubic and have roots -1 (with multiplicity of 2) and -2.
So, the equation is,
[Since, when a , b , c are the roots of a cubic equation, the equation is
given by 
]
To get the maximum height, we first determine the time at which this maximum height is attained by differentiating the given equation and equating the differential to zero.
h(t) = -0.2t² + 2t
Differentiating,
dh(t) = -(0.2)(2)t + 2 = 0
The value of t is equal to 5. Substituting this time to the original equation,
h(t) = -0.2(5²) + 2(5) = 5 ft
Thus, the maximum height is 5 ft and since it will take 5 seconds for it to reach the maximum height, the total time for it to reach the ground is 10 seconds.
Answers: maximum height = 5 ft
time it will reach the ground = 10 s
Answer:
58
Step-by-step explanation:
<u>Order of operations:</u>
- Parentheses
- Exponents
- Multiplication-Division
- Addition-Subtraction
<u>Solve:</u>
56-12 / 6+4
56 - (12/6) +4 { No Multiplication but do have Division} (12/6 = 2)
56 - 2 + 4 {Subtraction ⇒ 56-2 = 54}
54 + 4 { Addition ⇒ 54 + 4 = 58}
<u>Answer = </u>58
