Answer:
t = 2 s= 96
t = 3 s = 64
t = 4 s= 32
t= 5 s = 0
t= 6 s = -32
t = 7 s = -64
t = 8 s = -96
t= 9 s = -128
Step-by-step explanation:
We have the equation of the position of the rocket as a function of time t.
The instantaneous velocity of the rocket as a function of time is given by the derivation of the position with respect to time.
So
So
t = 2 s= 96
t = 3 s = 64
t = 4 s= 32
t= 5 s = 0
t= 6 s = -32
t = 7 s = -64
t = 8 s = -96
t= 9 s = -128
No, his mom would not be correct if he can read 1.5 pages for every 1 his friend reads then he could read 10 more pages than his friend because .5*20=10 and 20+10=30Pages
The system of equations can be used to find the cost of a night's stay and the cost of a meal is:
2n + 5m = $395
5n + 11m = $959
<h3>
Simultaneous equations</h3>
Simultaneous equations are two or more groups of equations. These equations have to be solved together at the same time in order to determined the required valued. The two above equations have to be solved in order to determine the cost of a night's stay and the cost of a meal.
