The option that can be used to support the idea that the set of polynomials is closed under multiplication is; Option C: (10x^(0.5) - 8)(5x^(0.5) + 4)
<h3>What is the Closure property under multiplication?</h3>
When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. It is pertinent to note that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Thus, we can also say that the polynomials are closed under multiplication.
Now, looking at the options, we can say that option C is the only polynomial that is closed under multiplication because its' variables and exponents will not change;
(10x^(0.5) - 8)(5x^(0.5) + 4)
The output will retain the same thing.

Answer:
A. $1,110
B. 50 units.
Step-by-step explanation:
A. Substitute 
into the function 
for calculate the time in hours required for the worker to produce 18 units:
Now you need to substitute 
into the function 
to calculate the amount in dollars she will be paid for 74 hours:
She will be paid $1,110.
B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute 
into the function and solve for T (to find the number of hours she requires to work to be paid $3,030)
Now, substitute 
into and solve for x, to calculate the number of units she produces in 202 hours:
She would need to produce 50 units to be paid $3,030
Answer:
8X +8
Step-by-step explanation:
Answer:
20 feet above sea level.
Explanation:
This can be solved by looking at the Rate of Change. It is given that for ONE minute that passes by, her elevation increases by ONE foot.
With this rate, after 20 minutes, the elevation can be shown as:
20 min × 1 foot= 20 feet.
