Answer:
The equation for height is given as
S= -16t2 +V 0 t
Also given
V0 = 128 ft/s
Substituting 192 = -16t2 +128t
Which is simplified as
t2 -8t +12 =0
Which gives t = -2 sec and t= 6 sec ( -2 can be ignored)
Using S = -16 *6*6 +128 *6 = 192 ft

20 is the greatest common factor cause it goes into 20 once and 40 twice
Answer:
the point of interception is where the graphs meets
in this case we will solve using substition method
x + 5y = 8 .... 1
-x + 2y = -1 .....2
solve for the equation
x = 8 - 5y ...... 3
solve the equation in equation 2
-x + 2y = -1
-(8-5y ) + 2y = -1
-8 +5y + 2y = -1
7y = -1 + 8
7y = 7
divided by 7 on both sides
y = 1
solve the value of y in equation 3
x = 8 - 5y
x = 8 - 5(1)
x = 8 -5
x = 3
the point of interception (3 ; 1)
In simplest form the fraction 60/78 reduces to 10/13
Answer:
50
