Answer:
The ball will take 2.6 seconds to hit the ground again.
Step-by-step explanation:
Sam kicks a soccer ball from the ground. The height of the ball (in feet) can be modeled with the function, h(t) = −16t(t − 2.6), where t is the time in seconds after the ball is kicked.
So, the ball will be at ground when h = 0 = - 16t(t - 2.6)
⇒ t = 0 or t = 2.6.
Therefore, the ball will take 2.6 seconds to hit the ground again. (Answer)
Using Pathogorean Theorem.....
40 = the square root of 24^2 + 32^2
40 = the square root of 576 + 1024
40 = the square root of 1600
40 = 40
0 / 6 is equal to 0 because anything that divides 0 will always be zero but never if the problem is 6/0
Answer:
<em> f ( x ) = - 2x^2 + 3x + 1</em>
Step-by-step explanation:
If f (x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;
− ∞ < x < ∞, while y > − ∞
Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;
If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;
<em>Solution; f ( x ) = - 2x^2 + 3x + 1</em>, where the degree is 2, the LCM ⇒ - 2
2 lines I think, not sure though
