Answer:
The correct option is b: 6 seconds.
Step-by-step explanation:
The formula is:
Where:
t: is the time
h: is the height = 384 ft
When the stone hit the ground, h = 0
To solve the above quadratic equation we need to use the following formula:
(1)
Where:
a: is the coefficient of t² = -16
b: is the coefficient of t = 32
c: is the independent term = 384
By entering the above values into equation (1) we have:
Since we can not take the negative value of time (t₂) equal to -4, the answer is 6 seconds.
Therefore, the stone will hit the ground in 6 seconds. The correct option is b: 6 seconds.
I hope it helps you!
The graphic you are looking for looks like the one shown in the attached figure.Remember that to graph a line you need two points, which you give them. The equation of the line you are looking for in this case will be given by y = 2x + 1
Only choices B and C are in the 3rd quadrant. The point B(-4, -1.5) is not inside the circle or the rectangle.
The appropriate choice is ...
C. (-1.5, -2)
Answer:
The answer would be 15
x = 15
Step-by-step explanation:
6x = 5x +15
Subtract 5x from both sides
x = 15
Try testing now by putting in the value
6(15) = 5(15) + 15
Distributive Property
90 = 75 + 15
Add
90 = 90
Now you know for a fact that this answer is correct.
