Answer:
Step-by-step explanation:
The graph shows the growth rate of a certain bacteria in a lab, where the number of bacteria depends on the number of hours since the start of the experiment. C 60 bacteria.
1. Sin 240 degree = -sin ( 240 -180 degree) = -sin (60 degree)
2. Tan 130 degree = -tan ( 180 - 130 degree) = -tan 50 degree
3. sec 305 degree = sec ( 360 - 305 degree) = sec (55 degree)
4. cos 95 degree = -<span>cos (180 - 95 degree ) = -cos 85 degree</span>
5. csc 185 degree = -sin 5 degree
36 for the first one 39 for the second one
1. BC is 1+3=4 (units)
2. AD is 3+5= 8 (units)
3. Draw the altitude CH from point C, as shown in the figure.
4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.
5.



6. AB=CD=4.47 because the trapezoid is isosceles.
7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)
