A rubber ball is dropped onto a hard surface from a height of 8 feet, and it bounces up and down. At each bounce it rises to 90

Setler [38]

A. 8 feet * 0.9 = distance after first bounce
h(n) = 8 * 0.9^n

b. 8 * 0.9^14 = 1.83 feet to 2 d.p.
1.83 * 12 = 21.96 inches

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across

nasty-shy [4]

Answer:

Domain is $[0,18]$

Average rate of change of bacteria per minute is -3333.33.

Step-by-step explanation:

Domain is the possible values of $x$ .

From the graph, it's clear that the $x$ values ranges from 0 to 18 as the end points of the graph are $(0,60)$ and $(18,0)$

So, domain of the function is $[0,18]$ .

Now, average rate of change is negative as there is bacteria decay.

Average rate of change is given as the negative ratio of y intercept to the x intercept.

Here, x-intercept is 18 and y-intercept is 60000.

So, average rate of change is given as,

$R_{avg}=-\frac{60000}{18}=-3333.33$

Therefore, average rate of change of bacteria per minute is -3333.33.

What is the solutions to the equation?

Hi,

Solving:

$x^{3} + 3x^{2} - 4x - 12 = 0 \\ {x}^{2} \times (x + 3) - 4x - 12 = 0 \\ {x}^{2} \times (x + 3) - 4(x - 3) = 0 \\ (x + 3) \times ( {x}^{2} - 4) = 0 \\ x + 3 = 0 \\ {x}^{2} - 4 = 0 \\ \\ (results) \\ x1 = - 3 \\ x2 = - 2 \\ x3 = 2$

Hope this helps.
