Answer:
Step-by-step explanation:
Given that a rock is thrown vertically upward from the surface of an airless planet. It reaches a height of 
where t is expressed in seconds
The rock goes upto a height where the velocity becomes 0 and then it starts falling down by gravity
Velocity at time t = s'(t) = 
This becomes 0 when t =15 seconds
Hence at 15th second the rock starts falling and upto
s(15) =
metres high it goes
The time taken to reach highest point is = 15 seconds.
Hi there!
To solve this problem, we need to simplify.
5x + 32 = 4 - 2x
7x + 32 = 4
7x = -28
x = -4
Hope this helps!
Find Slope: 0
1 - 1
------
-5 - - 8
It Has A Zero Slope (Neither)
11/2 * -11/4 = (11*-11) / 2*4 = -121 / 8
= -15 1/8 answer
-2 1/4 * -4 1/2
= -9/4 * -9/2
= 81/8
= 10 1/8 answer
