D) 111
Step-by-step explanation:
Sloane kicked a soccer ball off the ground at a speed of 48 feet per second. the height of the ball can be represented by the function h(t) = −16t2 48t, where t is the time in seconds. how many seconds did the ball travel before returning the ground? t = 0.33 seconds t = 3 seconds t = 16 seconds t = 48 seconds
Considering the function for it's height, it is found that the ball traveled for 3 seconds before returning to the ground.
What is the function for the ball's height?The height of the ball after t seconds is given by:
h(t) = -16t² + 48t.
It is at the ground at the instants of t for which:
h(t) = 0.
Hence:
-16t² + 48t = 0
-16t(t - 3) = 0.
We want t different of 0, hence:
t - 3 = 0 -> t = 3.
The ball traveled for 3 seconds before returning to the ground.

The value of a motorcycle each year follows the sequence $12,000 $9,600, $7,680, $6,144
Which formula represents the recursive definition of the sequence where n represents the number of years?
The recursive definition of the geometric sequence is given by:
A. [tex]a_n = (0.8)a_{n-1}[/tex]
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The basic recursive relation is given as follows:
[tex]a_n = qa_{n-1}[/tex]
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, considering the given sequence, the common ratio is given by:
[tex]q = \frac{6144}{7680} = \frac{7680}{9600} = \frac{9600}{12000} = 0.8[/tex]
Hence option A is correct.

The values of the motorcycle follows a geometric sequence
The recursive definition of the sequence is (a) [tex]a_{n} = 0.8a_{n-1[/tex]
How to determine the recursive definition?The values are given as:
$12,000 $9,600, $7,680, $6,144
Calculate the common ratio using:
r = a2/a1
So, we have:
r = 9600/12000
Divide
r = 0.8
Recall that:
r = a2/a1
So, we have:
a2/a1 = 0.8
Multiply both sides by a1
a2 = 0.8a1
Rewrite as:
[tex]a_{2} = 0.8a_{2-1[/tex]
Substitute n for 2
[tex]a_{n} = 0.8a_{n-1[/tex]
Hence, the recursive definition of the sequence is (a) [tex]a_{n} = 0.8a_{n-1[/tex]

Answer:
t = 3 seconds
Step-by-step explanation:
You can think of this as a quadratic and find the zeros. i will use x and y to make it easier.
y = -16x^2 + 48x
y = (x)(-16x+48)
y = (-16)(x)(x-3)
This means your zeros are at x = 0 and x-3 = 0, so 0 and 3.
0 is when the ball leaves the ground, so 3 is when it returns.

30th percentile = 105 90th percentile = 176
Answer:
30th percentile = 105 90th percentile = 176
Step-by-step explanation:
Arrange the data set in order from smallest to largest:
100, 100, 105, 113, 129, 132, 146, 152, 176, 200
30th percentile
r = number of data values = 10
q = percentile = 30
q/100 = 30/100 = 0.3
q/100 × r = 0.3 × 10 = 3
Therefore, count the 3rd number in the ordered set.
⇒ 30th percentile = 105
90th percentile
r = number of data values = 10
q = percentile = 90
q/100 = 90/100 = 0.9
q/100 × r = 0.9 × 10 = 9
Therefore, count the 9th number in the ordered set.
