Answer:
the second one it shows it going up
The practical domain is all real numbers from 4 to 9, inclusive.
The practical range is all real numbers from 49.6 to 111.6, inclusive.
These are the correct options.
Explanation:
Given function is f(t) = 12.4t
Let us assume that Nate works 'x' hours so 4<x<9
And multiplying the hours with his earnings we get the range.
4*12.40=49.6 and 9*12.40=111.6. Let the amount earned be represented by y
Hence, domain can be represented as 4<x<9 and range can be represented as 49.6 < y < 111.6
The time it would take for the bacteria to reach 1119 is 5.83 hours
<h3>Calculations and Parameters:</h3>
Given the function:
- Initial amount= 50
- amount after 3 hours= 80
To find the exponential growth;
80 = 
If there is a constant growth, then to get to 1119:
1119= 
3.8 = 0.533*t
t= 5.83 hours
Therefore, it would take 5.83 hours for the bacteria to increase to 1119.

Answer:
20
Step-by-step explanation:
Vertical angles are always equal to each other. So the answer is
3x + 4 = 73 - 9 Are you sure this is what the question is?
3x + 4 = 64 Subtract 4 from both sides
<u> -4 -4</u>
3x = 60 Divide by 3
3x/3 = 60/3
x = 20
