Answer:
The rocket will take 9.25 seconds to return to ground
.
Solution:
Given:
Initial velocity = 148 ft per seconds
Height "h" after "t" seconds is given by equation:
To find:
Time taken by rocket to return to ground =?
Solution:
The time taken by rocket to return to ground can found by substituting h(t) = 0 in the given equation.
Taking t outside
t(-16t + 148) = 0
Zero product property. The zero product property states that if a⋅b = 0 then either a or b equal zero. This basic property helps us solve equations like (x+2)(x-5) = 0
So for above equation we get,
t =
t = 9.25
When t = 0 , the rocket would not left the ground. So ignore t = 0
So t = 9.25
Answer: The speed was 4.1 MB/sec.
We first find the amount that was transferred within the first 125 seconds:
549-36.5=512.5
Now we divide this by 125, the number of seconds:
512.5/125 = 4.1
The speed of the transfer is 4.1 megabytes per second.
It took 235 seconds for the drive to be completely filled.

Step-by-step explanation:
Answer:
Mean = 2.95
Median = 3
Step-by-step explanation:
The mean of the number of visits of 40 adults to the gym is
The median of the data is the average number between 20th and 21th terms (because 40 is even number, so the middle term is the average between two middle terms).
20th term = 3 visits
21th term = 3 visits
Hence, median is 3 visits
