Start by writing a formula, where
is Brad's purchase price and
is the original price.

Subtract
from both sides.

Multiply both sides by
.

Answer:
2 < AB < 18
Step-by-step explanation:
Answer:
7 4/5
Step-by-step explanation:
2 2/5 = 12/5
3 1/4 = 13/4
12/5 x 13/4 = 156/20 = 7 16/20
7 16/20 / 4 = 7 4/5
True
Note that:

The graph of sine and cosine functions are very similar. They only have a shift in the x -axis.
That is, sin x = cos (90 - x)
Since there is a great similarity between the sine and cosine graphs, and the secant graph is an inverse of the cosine graph, the graph of sine can be used to construct the graph of the secant function
Mathematically:
since sec x = 1 / cos x
and, cos x = sin (90 - x)
therefore, sec x = 1 / sin (90 - x)
The graphs of the sine and secant functions are attached to this solution
