Answer:

The answer is x=-2 and x=4

Step-by-step explanation:

The attachment 1 is the graph of f(x), the attachment 2 is the graph of g(x)

Mergin the two functions, you will have this

Wichh shows you that the 2 graph intersect when x=2 and x=4

It is more straight to solve the equation

\frac{-x^{2} }{2} = -x-4

zvonat [6]

Answer: a) 124,596, b) 2142691552.

Step-by-step explanation:

Since we have given that

Number of distinguishable balls = 24

Number of boxes = 6

(a) In how many different ways can this be done?

^{24}C_6\\\\=134,596

(b) In how many different ways can this be done if box 1 must get 12 balls, box 2 must get 7 balls, box 3 must get 5 balls, and boxes 4, 5, and 6 must be empty?

Number of ways would be

\dfrac{24!}{12!7!5!}=2142691552

Hence, a) 124,596, b) 2142691552.

Genesis throws a ball up in the air. The graph below shows the height of the ball hh in meters after tt seconds. Find the interv
Juli2301 [7.4K]

We conclude that the interval in which the function decreases is (1.5, 3]

<h3>In which interval is the ball's height decreasing?</h3>

The ball is decreasing when the graph, reading from left to right, is going downwards.

Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.

And we can see that the vertex is at x = 1.5

And we also see that the graph of the function ends at x = 3.

Then we conclude that the interval in which the function decreases is (1.5, 3]
