Answer:
Answer B is the correct answer..
cot(theta)=cos(theta)/sin(theta)
Step-by-step explanation:
In simplest radical form
= √-3
= -3^(1/2)
or
= √-3
= √3i
i is imaginary number, you can write it if you find a negative number in a square root
Answer:
The cumulative frequency distribution is
<em>Class Cumulative</em>
<em>Interval frequency</em>
35-39 11
40-44 33
45-49 77
50-54 90
55-59 156
60-64 244
65-69 255
Step-by-step explanation:
<em>Class </em>
<em>Interval F C.F</em>
35-39 11 11
40-44 22 11+22=33
45-49 44 33+44=77
50-54 13 77+13=90
55-59 66 90+66=156
60-64 88 156+88=244
65-69 11 244+11=255
The first column contains class interval. The second column denoted by F contains frequencies. The third column contains cumulative frequencies denoted as C.F.
Answer: Ogro that is 2727
Step-by-step explanation:
Answer:
perimeter of the figure = 37 ft
Step-by-step explanation:
r = 1/2 × (12 - 3 - 3)
r = 1/2 × 6
r = 3 ft
circumference = 2 π r
circumference = 2 × 3.14 × 3
circumference = 18.84
perimeter of the figure = 3 + 3 + 3 + 3 + 3 + 3 + 18.84
perimeter of the figure = 36.84
perimeter of the figure = 37 ft
