I think the answer is 0.399
the "9" is repeated.
Answer:
A
Step-by-step explanation:
Given
3![(1.5)^{t}](https://tex.z-dn.net/?f=%281.5%29%5E%7Bt%7D)
When the culture was created t = 0, thus
3
= 3 × 1 = 3
That is there were initially 3 bacteria in the culture → A
Answer:
GH = 6.3 units
Step-by-step explanation:
Assuming that 1 box represents 1 unit, the coordinate pair of G = (-2, -3), while H = (0, 3).
Distance between G and H = ![d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%28x_2%20-%20x_1%29%5E2%20%2B%20%28y_2%20-%20y_1%29%5E2%7D%20)
Let,
![G(-2, -3) = (x_1, y_1)](https://tex.z-dn.net/?f=%20G%28-2%2C%20-3%29%20%3D%20%28x_1%2C%20y_1%29%20)
![H(0, 3) = (x_2, y_2)](https://tex.z-dn.net/?f=%20H%280%2C%203%29%20%3D%20%28x_2%2C%20y_2%29%20)
![GH = \sqrt{(0 - (-2))^2 + (3 - (-3))^2}](https://tex.z-dn.net/?f=%20GH%20%3D%20%5Csqrt%7B%280%20-%20%28-2%29%29%5E2%20%2B%20%283%20-%20%28-3%29%29%5E2%7D%20)
![GH = \sqrt{(2)^2 + (6)^2}](https://tex.z-dn.net/?f=%20GH%20%3D%20%5Csqrt%7B%282%29%5E2%20%2B%20%286%29%5E2%7D%20)
![GH = \sqrt{4 + 36} = \sqrt{40}](https://tex.z-dn.net/?f=%20GH%20%3D%20%5Csqrt%7B4%20%2B%2036%7D%20%3D%20%5Csqrt%7B40%7D%20)

Answer:
The correct options are:
x= -1.1
x= 2.4
x = 6
Step-by-step explanation:
The roots of any polynomial can easily be determined by the graph. To find the roots from the graph, we just have to see the values of x, for which the value of whole polynomial becomes 0.
We can see in the graph that there are three points where the value of polynomial becomes 0. that are
At x= -1.1
At x= 2.4
At x = 6
Thus, these are the roots
