Answer:
The number is 6
Step-by-step explanation:
Let's say that the reciprocal of the number is x
1/2 + 3 = 1
3x = 1/2
divided both sides by 3
x = 1/6
Since x is the reciprocal of the number, flip 1/6 and you will get 6/1
6/1 is really just 6 so that's your answer.
Hope this helps :)
Answer:
4 square root 2
Step-by-step explanation:
the pythagorian theorem will look like this: 2^2+b^2=6^2
simpify: 4+b^2=36
get b by itself by subtracting four from each side: b^2=32
take the square root of 32 and simplify: 4sqrt2
Ok so If I am understanding the question correctly, you will multiply 5 x 6 = 30 so there are 30 Bulbs. So all except 3 were planted. So then you will subtract 3 from 30 like this 30-3=27. That is your answer. Just take a deep breath Math looks a lot harder than it really is.
If A is QIV, then 3π/2 ≤A≤2π;
we have to find out in what quadrant is A/2
(3π/2)/2≤A/2≤(2π)/2 ⇒ 3π/4≤A/2≤π
We can see that A/2 will be in QIII; therefore the sec (A/2) will be negative (-).
1) we have to calculate cos (A/2)
Cos (A/2)=⁺₋√[(1+cos A/2)/2]
We choose this formula: Cos (A/2)= -√[(1+cos A/2)/2], because sec A/2 is in quadrant Q III, and the secant (sec A/2=1/cos A/2) in this quadrant is negative.
Cos (A/2)=-√[(1+cos A)/2]=-√[(1+(1/2)]/2=-√(3/4)=-(√3)/2.
2) we compute the sec (A/2)
Data:
cos (A/2)=-(√3)/2
sec (A/2)=1/cos (A/2)
sec (A/2)=1/(-(√3)/2)=-2/√3=-(2√3)/3
Answer: sec (A/2)=-(2√3)/3
