Step-by-step explanation:
( secA + 1)( sec A - 1)
Using the expansion
( a + b)( a - b) = a² - b²
Expand the expression
We have
sec²A + secA - secA - 1
That's
sec² A - 1
From trigonometric identities
<h3>sec²A - 1 = tan ²A</h3>
So we have the final answer as
<h3>tan²A</h3>
As proven

Step-by-step explanation:
The function we have is:
This is a linear function.
We can find the slope (the rate of change) of this function, by comparing it to the general slope-intercept equation:
Where m is the slope (rate of change) and b is the y-intercept of the line.
By comparison, we see that m an b are:
Since we are asked for the value of the rate of change, the answer is the value of m:
which is option A.
Answer:
A. 34.95
