Answer:
5.5 seconds
Step-by-step explanation:
The function that gives the height of the object after t seconds falling is:
h = -16t^2 + 484.
To find the time when the object reaches the ground, we just need to use the value of h = 0 in the equation, and then find the value of t:
0 = -16t^2 + 484.
16t^2 = 484
t^2 = 30.25
t = 5.5 seconds
So the object will reach the ground after 5.5 seconds
Step-by-step explanation:
= 2x - 9y + 4x + 11y
First of all combining like terms
So
= 2x + 4x - 9y + 11y
= 6x + 2y
Now putting values
= 6 (-2) + 2(4)
= - 12 + 8
= - 4
Answer:
Step-by-step explanation:
Thus, 
It C. and if you need the equation for the area of a parallelogram its A=BH
X+ y = 44
x - y = 6
—————
2x = 50
x = 25
y = 44-x = 19
