Trevon is making payments on a computer that costs $1548. If he makes 12 equal payments, how much is three of his payments?
1 answer:
Answer:
The answer is 387. Let's see why.
Step-by-step explanation:
The computer costs $1548. And all the 12 payments are <u>equal.</u>
To find one payment we need to divide the total cost to the number of payments.
Each one of the payments is $129.
To find three payment we simply follow:
129 . 3 = <u>387</u>
Another solution can be;
Since we are looking for 3 of the payments we can divide it to the total payment
which equals to
And we can find the answer by multiplying it with the cost which gives;

Answer: option d. x = 3π/2
Solution:
function y = sec(x)
1) y = 1 / cos(x)
2) When cos(x) = 0, 1 / cos(x) is not defined
3) cos(x) = 0 when x = π/2, 3π/2, 5π/2, 7π/2, ...
4) limit of sec(x) = lim of 1 / cos(x).
When x approaches π/2, 3π/2, 5π/2, 7π/2, ... the limit →+/- ∞.
So, x = π/2, x = 3π/2, x = 5π/2, ... are vertical asymptotes of sec(x).
Answer: 3π/2
