T ∝ 1/v
<span>so, t = k/v or tv = k </span>
<span>Then, with t = 2.5 and v = 5 we have: </span>
<span>2.5 = k/5 </span>
<span>so, k = 12.5 </span>
<span>Therefore, t = 12.5/v or vt = 12.5 HOPE IT HELPED</span>
We know that
1+cot ²∅=csc² ∅
cot ∅=4/7
so
1+(4/7)²=csc² ∅
csc² ∅=1+(16/49)
csc² ∅=(65/49)
csc ∅=(√65)/7
remember that
csc ∅=1/sin ∅
sin ∅=1/csc ∅------> sin ∅=7/√65-----> sin ∅=(7√65)/65
the answer is
the best identity to find sin ∅ is
1+cot ²∅=csc² ∅
True!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
765
Step-by-step explanation:
Given in the question,
number of people to be choose with at least 5 women in it = 8
There are 2 ways to choose 8 members
1)
5 women
(6C5)(10C3)
6x120
720
2)
6 women
(6C6)(10C2)
1x45
45
Our final answer is 720 + 45 = 765 ways
Formula to calculate
nCr = n! / r!(n-r)!
