Step-by-step explanation:

31) 1  1/4 × 8/9

multiply the denominator(4) with 1 which is 4 itself, then add 4 with the numerator(1) which is 5. therefore you will get,

⇒5/4 × 8/9

⇒ 5×8/4×9

⇒40/36

⇒10/9

32) 2/3 × 2  1/4

multiply the denominator(4) with 2 which is 8, then add 8 with the numerator(1) which is 9. therefore you will get,

⇒2/3 × 9/4

⇒2×9/3×4

⇒18/12

⇒3/2

33) 2  2/9 × 3/4

multiply the denominator(9) with 2 which is 18, then add 18 with the numerator(2) which is 20. therefore you will get,

⇒20/9 × 3/4

⇒20×3/9×4

⇒60/36

⇒5/3

34) 4/5 × 2  11/12

⇒4/5 × 35/12

⇒4×35/5×12

⇒140/60

⇒7/3

Exploring the graph of y equals cosine Theta​
irga5000 [103]

Answer:  see below

<u>Step-by-step explanation:</u>

The coordinates on the Unit Circle are (cos, sin). Since we are focused on cosine, we only need to focus on the left side of the coordinate. The cosine value (left side) will be the y-value of the function y = cos x

Use the quadrangles (angles on the axes) to represent the x-values of the function y = cos x.

Quadrangles are: 0°, 90°, 180°, 270°, 360°  <em>(360° = 0°)</em>

Together, the coordinates will be as follow:

\boxed{\begin{array}{c||c|c||c}\underline{(cos,sin)}&\underline{x=angle}&\underline{y=cosx}&\underline{\quad (x,y)\quad}\\(1,0)&0^o&1&(0^o,1)\\(0,1)&90^o&0&(90^o,0)\\(-1,0)&180^o&-1&(180^o,-1)\\(0,-1)&270^o&0&(270^o,0)\\(1,0)&360^o&1&(360^o,1)\end{array}}
