Answer:
y = 33.75 m/s.
Step-by-step explanation:
The graph of the rocket's velocity with respect to time looks as follows :
...(1)
Where x is time in seconds
We need to find the velocity of rocket after 15 seconds. Put x = 15 in equation (1).
Hence, the speed of the rocket after 15 seconds is 33.75 m/s.
Y= -3x+8
y= 3x+2
both points meet at points ( 1 , 5 )
solve algebraically:
-3x+8=3x+2
+3 +3
_________
8=6x + 2
-2 -2
_________
6/6= 6x/6
x=1
y=3(1)+2
y=3+2
y=5
points: (1,5)

is buying 3 books in a trilogy set for $24.81.
He will save $6.69 by buying the trilogy set instead of buying individual
books.
Each book costs the same amount
Let’s find out how much does each of the
3 books cost when purchased individually.
=> 3 books costs = 24.81 dollar in which he saved 6.69 dollar compare to
buying individual.
=> 24.81 + 6.69 = 31.5 dollars
=> 31.5 dollars / 3 = 10.5 dollars = the individual price of the books.

Answer:
Step-by-step explanation:
Volume of first container = 48 cm³
πr²h = 48 cm³
Second container:
height = (2/3)h
Volume of second container=
=(2/3)* first container's volume {πr²h = 48 cm³}
= 32 cm³
