Which expression is equivalent to (1-sin^2x)(sec x)

1 answer:

8 0

(1-sin²x)(sec x)

(1-sin²x) = cos²x (since sin²x +cos²x = 1)

(sec x) = 1/cosx

(cos²x) . (1/cosx) ==>(cos²x)/cosx) ==> ===> cosx

Answer:

f(x) = 6x +1

Step-by-step explanation:

Differences in x-values (first row) are 1, 1, 1.

Differences in y-values (second row) are 6, 6, 6.

The constant ratio of differences (6/1) tells you the function is linear, and has a slope of m = 6/1 = 6.

Using the first point in the form ...

y = mx + b

we have ...

y = 6x + b

7 = 6·1 + b . . . . (x, y) = (1, 7)

1 = b . . . . . . subtract 6

Then the equation can be written ...

y = 6x +1

In functional form, this is ...

f(x) = 6x +1
