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.

Step-by-step explanation:
Each friend will receive 7 pieces of candy after dividing it equally.
" Division is the method of distributing or sharing any group of items equally."
According to the question,
Total pieces of candy = 35
Total number of friends= 5
Division of candy between 5 friends
Number of candy each friend will received = 35 ÷ 5
= 7pieces
Hence, Each friend will receive 7 pieces of candy.

so the answer is 7
Given:
The coordinates of the point A and B are (-5,-1) and (4,1)
The point P on the directed line segment from A to B such that P is One-fourth the length of the line segment from A to B.
Thus, we have;
and
We need to determine the coordinates of the point P(x,y)
x - coordinates of the point P:
The x - coordinates of the point P can be determined using the formula,
Substituting the values, we get;
Thus, the x - coordinate of the point P is
y - coordinate of the point P:
The y - coordinate of the point P can be determined using the formula,
Substituting the values, we get;
Thus, the y - coordinate of the point P is
Therefore, the coordinates of the point P is
Hence, Option C is the correct answer.
Answer:
The answer is C
Step-by-step explanation:
b. What height will the ball be at the top of the third path?
Answer:
Step-by-step explanation:
The initial height of the ball is 0.5 m
Each curved path has 52% of the height of the previous path, i.e the height of the ball after one bounce will be,
The height of the ball after 2 bounces will be,
Hence the series becomes,
This is the case of Geometric Progression.
But as it is given that the initial height will be given by n=1, so the rules for finding the height f(n) after n bounces would be,
Putting n=3, we can get the height of the ball of the third path,
