Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object.
Have a wonderful day
Step-by-step explanation:
Since, f(x) is a cosine function, it is periodic.
<u>Maximum : ( - 1 + </u><u>10<em>k</em></u><em><u> </u></em><u>, 28)</u> ; where <em>k</em> belongs to <em>Z</em>
Minimum : (4 + 10<em>k</em> , 22)
<u>Cycle No. 1</u> : k = 1
(A) The first occurrence of highest temperature in the cycle is on <u>day 9</u> after June 1 i.e. ( <u>June 10</u>) with <u>28 °C</u>.
<u>Cycle No. 1</u> : k = 0
(B) The first occurrence of lowest temperature in the cycle is on <u>day 4</u> ( <u>June 15</u>) with <u>22 °C</u>.
Angle pairs 1 and 2 are vertical angles for they are opposite angles made by intersecting lines<span>. While angle pair x</span>° and 157° are supplementary because they make a straight line or 180° angle.
