The ball will hit the ground at 2 seconds.
Step-by-step explanation:
Given that,
The path of the ball = h(x)=−2x2+1x+6
Here,
x is the time while h is the height of ball.
When the ball will hit the ground, the height will become zero. Therefore,
h(x)=−2x2+1x+6
0 =−2x2+1x+6
or
2x2 -1x - 6 = 0
This is a quadratic equation, hence by applying quadratic equation formula:
here,
a = 2
b = -1
c = -6
Putting these values in formula, we get
x = 2, -3/2
As the time cannot be negative. Therefore, the ball will hit the ground at 2 seconds.
6(f)^0.5
is this what you meant?
There is a 50/50 chance she does or doesnt take a red marble out the back so its most likely 40 times because of how there are other 2 colors and she is putting back the marbles in the bag
Answer:
i believe itd be 66 dollars :D
hope this helps !!
Step-by-step explanation:
x - 18 = 48
add 48 and 18 and get the answer = $66
To answer the question above, directly substitute the given price which is $100 to all the x's of the given equation,
C = 0.765x + 0.06 (0.765x)
C = (0.765) ($100) + 0.06 (0.765) ($100) = 81.09
Thus, Chris would have to pay only $81.09.
