The motion of a swing can be modeled with a sinusoidal function. Timing the swing, Josh records a maximum height in front of the swing of 12 feet at 11 seconds and then a
maximum height of 12 feet at the back of the swing at 19 seconds. The minimum height
of the swing is 2 feet above the ground.
1. Sketch a graph of the sinusoid. Tell what each axis represents, by labeling them.
2. Insert a picture of your hand-drawn graph in the text box below.
3. Write an equation of the sinusoid. Use proper math formatting using the va on the
format menu, or insert a picture of your equation.
4. Predict the height when t = 13 seconds.
5. When is the third time the height of the swing is 4 ft?

Find the perimeter of the triangle with vertices  d(3, 4),  e(8, 7), and  f(5, 9). do not round before calculating the perimeter. after calculating the perimeter, round your answer to the nearest tenth.  

Students at a high school were asked about their favorite outdoor activity. the results are shown in the two-way frequency table below. fishing camping canoeing skiing total boys 36 44 13 25 118 girls 34 37 22 20 113 total 70 81 35 45 231 select all the statements that are true based on the given table. more girls chose camping as their favorite outdoor activity than boys. more girls chose canoeing as their favorite outdoor activity than those who chose skiing. more boys chose skiing as their favorite outdoor activity than girls. there were more boys surveyed than girls. twice as many students chose canoeing as their favorite outdoor activity than those who chose fishing. more students chose camping as their favorite outdoor activity than the combined number of students who chose canoeing or skiing.
