Citrus2011 [14]

Answer:

1385

Step-by-step explanation:

1) the difference is d=25-8=42-25=17;

the sequence given in the condition is arithmetic one (linear relationship).

2) in order to calculate the value of the 82d term:

a(n)=a(1)+d*(n-1), where n - number of required term (it is 82), then

a(82)=8+17*(82-1)=8+1377=1385.

Dana is purchasing a new car that costs $24,650. Although Dana will be financing her car, she must pay sales tax, title, and tag

telo118 [61]

Dana must pay $1238.75 upfront.

Step-by-step explanation:

Given,

Cost of car = $24,650

Sales tax = 3.5%

Amount of sales tax = 3.5% of cost of car

Amount of sales tax = $\frac{3.5}{100}*24650$

Amount of sales tax = $\frac{86275}{100}=\$862.75$

Amount of title and tag fees = $376

Total upfront amount = Amount of sales tax + Amount of title and tag fees

Total upfront amount = 862.75+376 = $1238.75

Dana must pay $1238.75 upfront.

Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading c

antoniya [11.8K]

Answer:

Wikipedia defines polynomials as "an expression consisting of variables and coefficients."

You would think that F(x) would not be a polynomial, but you could think of it like this:

F(x) = 0x + 1050

So, yes, I suppose constant terms by themselves are polynomials, it's just that they only have one term and would not really be called a poly-nomial.

You should probably research some more just in case.
