A cherry falls from a tree branch that is 9 feet above the ground.
miss Akunina [59]
The cinematic equation is:
 h (t) = (1/2) * a * t ^ 2 + vo * t + h0
 Where,
 a: acceleration
 vo: initial speed
 h0: initial height
 Substituting values:
 h (t) = (1/2) * (- 32) * t ^ 2 + (0) * t + 9
 h (t) = - 16t ^ 2 + 9
 For t = 0.2 we have:
 h (0.2) = - 16 * (0.2) ^ 2 + 9
 h (0.2) = 8.36 feet
 To touch the ground we have:
 -16t ^ 2 + 9 = 0
 16t ^ 2 = 9
 t = root (9/16)
 t = 0.75 s
 Answer:
 
The height of the cherry after 0.2 seconds is:
 
h (0.2) = 8.36 feet
 
the cherry hits the ground at:
 
t = 0.75 s

What is the 50th term of the arithmetic sequence 3, 7, 11, 15, ... ?
zysi [14]

Answer:

B. 199

Step-by-step explanation:

We are given an Arithmetic sequence : 3, 7, 11, 15, ...

We are supposed to find the 50th term .

So, first consider the formula of nth term in Arithmetic mean:

a_{n} = a+(n-1)*d

where

a is first term of sequence

n is term position

d is common difference

a_{n}= the term you are supposed to find

Now,

a = 3 ( first term )

n = 50 th term ( given )

d = 7-3 = 11-7 = 4(common difference

Substitute these value in the formula given above

⇒a_{50} = 3+(50-1)*4

⇒a_{50} = 3+(49)*4

⇒a_{50} = 3+196

⇒a_{50} = 199

Hence ,The 50th term of given arithmetic sequence is 199

So, OPTION B is correct .
