Answer:
5secs
Step-by-step explanation:
Given the equation of the height expressed ad;
h(t) = - 16t^2 + initial height
Given that initial height = 400feet
h(t) = - 16t^2 + 400
The waste will hit the ground at when h(t) = 0
substitute
0 = - 16t^2 + 400
16t^2 = 400
t² = 400/16
t² = 25
t = √25
t = 5secs
Hence it will take the easte 5secs to hit the ground
Answer:
Option A= 250
Step-by-step explanation:
Coterminal angles are angles in standard positions having thesame terminal .
Coterminal angles are always negative and positive.
For example:
The coterminal angle of 30° is-
30 - 360 = -330
30 + 360 = 390
Therefore, -330 and 390 are coterminal.
So, to the question:
The angles between 0 -360 coterminal to -110 is 250.
Prove:
250 - 360 = -110
250 + 360 = 610
Option A is correct

Answer:
15th term =29/3
16th term = 31/3
Step-by-step explanation:
Given an arithmetic sequence with the first term a1 and the common difference d , the nth (or general) term is given by an=a1+(n−1)d .
First we find the 15th term
n=15
a1=1/3
d=1 - 1/3 = 2/3
Solution
1/3+(15-1)2/3
1/3+28/3
(1+28)/3
29/3
Lets find the 16th term
1/3+(16-1)2/3
1/3+30/3
(1+30)/3
31/3
