Answer:
12.8
Step-by-step explanation:
h(t) = -3t2 + 12t +96
Alicia wants to know when the drone will land on the ground.
1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the
equation
h(t) =
2) How many minutes after takeoff does the drone land on the ground?
minutes
The function can be written as: h(t) = - 3(t² - 4t - 32). As per quadratic equation, after take off, the drone will land on the ground after 8 minutes.
A quadratic equation is an equation that contains a variable with highest degree of 2.
Given, the height of the drone t minutes after take off is modeled by
h(t) = - 3t² + 12t + 96 = - 3(t² - 4t - 32)
Therefore, the function can be written as: h(t) = - 3(t² - 4t - 32)
Therefore, we can write the equation as:
t² - 4t - 32 = 0
⇒ t²- 8t + 4t - 32 = 0
⇒ t(t - 8) + 4(t - 8) = 0
⇒ (t + 4)(t - 8) = 0
Hence, (t + 4) = 0 and (t - 8) = 0
Therefore, t = -4, 8.
As 't' can't be negative, therefore, t = 8.
Therefore, after take off, the drone will land on the ground after 8 minutes.

Answer:
h(t) = -3(t-8)(t+4). and 8 minutes
Step-by-step explanation:
Answer:
1/2 × base times height
1)2×13×4
13×2
26cm2
Step-by-step explanation:
Area = (b×h) ÷ 2
=(18.7cm × 4cm) ÷ 2
=74.8cm ÷ 2
=37.4 cm2
Hope it helps :)
The first question's answer is:
0<-100x^2+350x-150
The second question "Look at the factorization shown below.
0 < –100x2 + 350x – 150
0 < –50(2x2 – 7x + 3)
0 < –50(2x – 1)(x – 3)
