Answer:
It Is O. 8
Step-by-step explanation:
Because you are suppose to round the number to the one in front of the other number
Answer:
the range of a function is the set of results solutions or output values (y)to the equation for a given input. to be honest a function only has one result for each domain.
Step-by-step explanation:
R there answer choices?
The population will reach 540 000 in 30.8 yr.
The formula for population growth is
<em>P</em>_<em>t</em> = <em>P</em>_0 × e^(<em>rt</em>)
540 000 = 270 000 × e^(0.0225t)
e^(0.0225t) = 2
0.0225t = ln2
t = (ln2)/0.0225 = 30.8

I believe your answer is:
![y = 7x - 3\leftarrow \text{No.}\\\\y = 150x \leftarrow \text{Yes.}](https://tex.z-dn.net/?f=y%20%3D%207x%20-%203%5Cleftarrow%20%5Ctext%7BNo.%7D%5C%5C%5C%5Cy%20%3D%20150x%20%5Cleftarrow%20%5Ctext%7BYes.%7D)

Here’s why:

⸻⸻⸻⸻
Since y = 7x - 3 does not pass the origin, it is not proportional. However, y = 150x does, so it is proportional.
