Simplify and write the trigonometric expression in terms of sine and cosine: sinx + cotx cosx=1/f(x)

Step-by-step explanation:

cot(x)=cos(x)/sin(x)

sin(x) + cos(x) * cos(x)/sin(x) = 1/f(x)

(sin^2 + cos^(x))/sin(x) = 1 / f(x)

1 / sin(x) = 1 / f(x)

Taking the reciprocal of both sides, we get

sin(x) = f(x)

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
