Below are sample questions representative of the exercises included on this worksheet and related TRIG.4 Model with mathematics using trigonometric functions skill assessments:

Problem 1Difficulty: Mastery

A tide app needs a model for the next 24 hours. High tides are at t = 2.5 and t = 14.9, with height 11.2 ft; low tide height is 1.6 ft. Which model and domain best fit?

AH(t) = 4.8cos((pi/6.2)(t - 2.5)) + 6.4, 0 <= t <= 24

BH(t) = 6.4cos((pi/6.2)(t - 2.5)) + 4.8, 0 <= t <= 24

CH(t) = -4.8cos((pi/6.2)(t - 2.5)) + 6.4, 0 <= t <= 24

DH(t) = 4.8cos((pi/12.4)(t - 2.5)) + 6.4, all real t

Solution & Explanation:The period is 14.9 - 2.5 = 12.4, so B = 2pi/12.4 = pi/6.2. The amplitude is (11.2 - 1.6)/2 = 4.8 and the midline is 6.4. The app models 0 to 24 hours.

Problem 2Difficulty: Mastery

Compare y = 6sin((pi/4)t) + 10 and y = 6cos((pi/4)(t - 2)) + 10. Which statement is true?

AThey are equivalent models with amplitude 6, period 8, and midline 10.

BThey have the same amplitude but different periods.

CThey have the same period but different midlines.

DThey cannot model the same situation because one uses sine and one uses cosine.

Solution & Explanation:cos((pi/4)(t - 2)) = cos(pi t/4 - pi/2), which equals sin(pi t/4). The models are equivalent and share the same amplitude, period, and midline.

Problem 3Difficulty: Mastery

A medication rhythm is modeled by C(t) = 2sin((pi/5)(t - 1)) + 7 on 0 <= t <= 10, where t is days. Which interpretation is correct?

AThe period is 10 days, the baseline is 7, and a peak occurs at t = 3.5.

BThe period is 5 days, the baseline is 2, and a peak occurs at t = 1.

CThe period is 10 days, the baseline is 7, and a low occurs at t = 3.5.

DThe period is 1 day, the baseline is 7, and the domain is all real numbers.

Solution & Explanation:The period is 2pi/(pi/5) = 10 and the midline is 7. Sine reaches a maximum when its argument is pi/2, so t - 1 = 2.5 and t = 3.5.
