Consider the function f(:1:) : 2 (cos (a: g) + 2) . Determine its amplitude, period, and midh'ne. Enter the exact answers. For the number 71', either choose 11' from the bar at the top or type in Pi (with a capital P). Ampliude: A = Number Period: P : B E" Midline: y = Number For the function (x) = 2cota determine its stretching factor and phase shift, and then graph it for two periods. Enter the exact answers. Stretching factor = Number Phase shift: Using your answers for the stretching factor and phase shift, select the correct graph of the function f(x) =2cotr. 107 -2 -21 -21If a loading ramp is placed next to a truck, at a height of 7 feet, and the ramp is 19 feet long, what angle does the ramp make with the ground? Round your answer to one decimal place. The ramp makes an angle of Number degrees with the ground. Use basic identities to simplify sing a + cos x sinx. Enclose arguments of functions in parentheses. For example, sin (2x). Remember that writing sin(x) to the fourth power as sin (a) is just a mathematical shorthand. You should write it as (sin (a) )4, which is what Mobius expects. sing x + cos x sin x =Rewrite sin (a: + %) in terms of sin :I: and cos :12. Enclose arguments of functions in parentheses. For example, sin (23:). sm(m+%)= | lam
