Data:
Initial price: $67.000
Price decrease: .30 each year t
The general form of a model of exponential decrease is:
Where P0 is the initial price, r is the rate of decrease and t the number of periods.
Then, for the given situation you get the next equation:
Then, the answer is the option D.
Answer: No
Step-by-step explanation:
The height is 5 units and the length is 7
Use the Pythagorean theorem and you get 8.6
2y(x3+9x-10x2-45) not much to be taken as a common factor
-4x+3+2x-6
The answer is -2x-3
Answer:
A choice
Step-by-step explanation:
sec is defined as 1/cos.
cos is again defined as adjacent to hypotenuse.
We know that adjacent is x and hypotenuse is r.
Therefore:- cos is x/r
Now sec is 1/cos = 1/(x/r)
1 ÷ x/r is 1•r/x
Thus:-
sec is r/x
