Question 1195069: I need help with this please:
The military is performing missile tests. A new missile is launched from the ground and it's path can be modelled by the quadratic equation y=-4(x-10)^2+400, where y is the missile's height in meters and x is the time in seconds. 10 seconds later, a second heat-seeking missile is launched to intercept and explode the first missile before it reaches the ground. The second missile's path can be modelled by the quadratic equation y=2(x-20)^2+300, where y is its height in meters and x is its time in seconds. At what time and height should the second missile reach and explode the first missile.

Question 1195454: The military is performing missile tests. A new missile is launched from the ground and it’s path can be modelled by the quadratic equation
y=-4(X-10)^2 +400 , where y is the missile’s height in meters and x is the time in seconds. 10 seconds later, a second heat-seeking missile is
launched to intercept and explode the first missile before it reaches the ground. The second missile’s path can be modelled by the quadratic equation
y= -2(x-20)^2+300
, where y is its height in meters and x is its time in seconds. At what time and height should the second missile
reach and explode the first missile?

Question 1195453: A football is kicked straight up into the air. Its height above the ground is approximated by the relation y=25x - 5x^2
,where y is the height of the ball in meters and x is the time in seconds.
There are two times when the football is 27.5 m in the air, on the way up and on the way down.
Joe realizes that using the equation
y= 27.5
, he can determine the two times the ball is 27.5
meters in the air. Algebraically or graphically determine these two times.
