Answer:
Step-by-step explanation:
- The function f(x) shows the number of cell tower users after "x" years from the year 2010.
- Then, the dependent varible of the function f(x) are the number of cell tower users after x years from 2010, and the independent variable of this function, "x", are the years that have passed since 2010, included 2010.
- This means that the independent variable should take the values of the years from 2010, which represent the domain (values that x variable can take), that are all the years between 2010 and 2019 (which is the present year).
Answer:
D $359.60
Step-by-step explanation:
We start by calculating the per-person cost for a full car and for a full minibus.
For a car with 4 members, the cost per person is:
A car with 3 members will cost per person:
For the minibus (10 people) the cost per person is:
The full car is cheaper per person, but if we fill 4 cars with 4 people each, there is one person left, and it will cost an additional $50.
This option will cost:
As a 3-person car is considered full and have discount, we can arrange 2 cars with 4 people (8 people total) and 3 cars with 3 people (9 people total), and then complete the team of 17.
This would have the cost:
The third option, would be use the minibus (10 people) and 2 cars: one with 4 people and the other with 3. This would have a cost of:
As this are the best options, the lowest cost is $359.60.

Answer:
29.7
Step-by-step explanation:
Right now you have three values:
a=45
c=23
B=36°
(note: a side is opposite of its corresponding angle in a triangle)
Since you need to find b and you have the other 2 sides and b’s corresponding angle, you use the law of cosines. The formula law of cosines, in this problem, will be:
b^2 = (a^2) + (c^2) - 2ac(cosB)
Now you just substitue in your values:
b^2 = (45^2) + (23^2) - 2(45)(23)(cos 36°)
Simplify the equation:
b^2 = 2025 + 529 - 2070(cos36°)
b^2 = 2554 - 1674.6652
b^2 = 879.3348
Now you take the square root so you can get rid of the square on b:
b = 29.7 (rounded to the nearest tenth)
