Answer:
<u><em>105</em></u>
Step-by-step explanation:
<em>a = 5</em>
<em>=> 3a(2 + a)</em>
<em>=> 3(5)(2 + 5)</em>
<em>=> 15(7)</em>
<em>=></em> <u><em>105</em></u>

Step-by-step explanation:
For a. you are asked to evaluate f(0). This is a piecewise function with different domains for each piece of the function. You can only evaluate f(0) in the function that has a domain that allows 0 in it. In the first domain, it says
x < -3. 0 is not less than -3, so 0 is not in that domain, so you will not use that "piece" of the function to evaluate f(0).
In the next domain, it says that x is greater than or equal to -3 and less than 0. Again, 0 is not included in that domain, so we can't use that "piece" of the function to evaluate f(0).
The last domain says that x is greater than OR EQUAL TO 0, so this is where we evaluate f(0):
f(0) = -0 - 4 so
f(0) = -4
When we want to evaluate f(2), we follow the same rules. Find the piece of the function that allows 2 in its domain. That's the middle piece:
f(2) = 2(2) - 6 so
f(2) = -2

Step-by-step explanation:
In a self-service area, cross-contamination can occur when there are bacteria in a kitchen that are transmitted to the food by direct contact. Typically in the culinary, a knife or cutting board is the most common kitchen devices that appear to be tainted by cross contamination. In reality, it's not only bacteria that are transported or relocated from one location to another, but may also be a virus or toxin of some kind or even a cleaning product, so whatever it is, it is considered a cause of cross-contamination if it eventually comes into contact with somebody's food.
