Step-by-step explanation:
All you have to do is figure out the bases of the figure and use the 12 and 13 in your problems and you should be able to get the right answer.
Answer:
Verified below
Step-by-step explanation:
We want to show that (Cos2θ)/(1 + sin2θ) = (cot θ - 1)/(cot θ + 1)
In trigonometric identities;
Cot θ = cos θ/sin θ
Thus;
(cot θ - 1)/(cot θ + 1) gives;
((cos θ/sin θ) - 1)/((cos θ/sin θ) + 1)
Simplifying numerator and denominator gives;
((cos θ - sin θ)/sin θ)/((cos θ + sin θ)/sin θ)
This reduces to;
>> (cos θ - sin θ)/(cos θ + sin θ)
Multiply top and bottom by ((cos θ + sin θ) to get;
>> (cos² θ - sin²θ)/(cos²θ + sin²θ + 2sinθcosθ)
In trigonometric identities, we know that;
cos 2θ = (cos² θ - sin²θ)
cos²θ + sin²θ = 1
sin 2θ = 2sinθcosθ
Thus;
(cos² θ - sin²θ)/(cos²θ + sin²θ + 2sinθcosθ) gives us:
>> cos 2θ/(1 + sin 2θ)
This is equal to the left hand side.
Thus, it is verified.
Number 9 is 36 because there are 18/40 who feel safe, so it multiplied would be 36. C
The cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94
<h3>Cost of each turkey</h3><h3 />
- Total number of turkey bought = 72
- Total cost = $67.9
Cost of each turkey = Total cost / Total number of turkey bought
= 67.9 / 72
= 0.943055555555555
Approximately,
Cost of each turkey = $0.94
Therefore, the cost of each turkey, if each is a smudge that represents some unreadable digit is $0.94
