Answer:
80x
Step-by-step explanation:
If you pay 80 a month then to find the total you have paid after any number of months you would multiply amount times time which in this case is 80
a constant is the a number on its own so in this case there would be none
a coefficient is the number in front of a variable. Since the equation is 80x the coefficient is 80
The answer is 6 pi because you have to divide 18 by 3. That gives you 6.

Answer:
(c) 14.5 cm
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(65°) = BC/BA
BC = BA·sin(65°) ≈ (16 cm)·0.9063 ≈ 14.501 cm
BC ≈ 14.5 cm

<em>Additional comment</em>
As is often the case, a simple estimate is all that is needed to identify the correct answer choice.
You only need to know how the long side of a right triangle compares to the others. In an isosceles right triangle, both legs are √2/2 ≈ 0.71 times the hypotenuse. The long side of a right triangle will never be shorter than that. This means the long side must be greater than about 11.2, and cannot be greater than 16. There is only one answer choice in that range.
