Stacie is choosing between two careers. Working for company A, Stacie will make $45,000 the first year and will receive an addit
fomenos

The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is

S=\frac{n}{2}(2a +(n-1)d)

Where a is the first term, n is the nth term, d is the common difference

On substituting there values,we will get

S =\frac{30}{2}(2*42000+(30-1)1800)

= 15(84000+52200) = 15*136200 =2043000

And for company A, it is

S= \frac{30}{2}(2*45000+(30-1)1500 ) = 15(90000+43500)=2002500

Difference between them =2043000-2002500= 40500

So the correct option is the second option .

FIRST PERSON TO ANSWER GETS BRAINLIEST OR FIVE STARS Define the domain and range of the function.
uysha [10]

Answer:

Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

The domain are the x-values included in the function (the horizontal axis).

The range are the y-values included in the function (the vertical axis).

The two arrows on the ends of the line (pointing upwards and downwards respectively) indicate that the function goes in those direction for infinity. Therefore, if there are an infinite amount of y-values, the range is (-∞, ∞).

While the slope is quite steep, there is still a slope and slowly "expands" the line on the horizontal axis. Because there is no limit to the y-values, the domain will also expand infinitely. Therefore, the domain is also (-∞, ∞).

Sam needs a web designer. Designer A is offering her services for an initial $450 in addition to $105 per hour. Designer B is of
gogolik [260]

Answer:

After 5 hours the two would charge the same amount of money.

Step-by-step explanation:

Designer A:  $450 + ($105/hr)x, where x is the number of hours worked;

Designer B:  $725 + ($50/hr)x

Equating these two formulas, we get:

$450 + ($105/hr)x = $725 + ($50/hr)x

Subtracting $450 from both sides:  ($55/hr)x = $275

Dividing both sides by $55 yields the number of hours worked:

x = $275/$55 = 5

After 5 hours the two would charge the same amount of money.
