Answer:
BAD=100° (given)
ADC=105° (180-75)
DCB=50° (vertical angles)
CBA=105° (same as ADC)
Tgα = tan(α) = sqrt(2)/1 = opposite/ adjacent
opposite = sqrt(2)
adjacent = 1
hypotenuse = sqrt(opposite^2 + adjacent^2)
= sqrt(sqrt(2)^2 + 1^2) = sqrt(3)
sin(α) = opposite/hypotenuse
= sqrt(2)/sqrt(3)
cos(α) = adjacent/hypotenuse
= 1/sqrt(3)
now we can calculate the value of
5sin²α+3cos²α / 3sin²α-5cos²α
... do the math
C. 4 and 6. 6*4=24, 4/6=2/3 (width is 2/3 the length).
Answer: The second derivative would be
Step-by-step explanation:
Since we have given that
We will find the first derivative w.r.t. 'x'.
So, it becomes,
Then, we will find the second derivative w.r.t 'x'.
Hence, the second derivative would be
Answer: OPTION C.
Step-by-step explanation:
For this exercise it is important to remember the the following properties:
1. The Produtct of Powers Property states that:
2. The Quotient of Powers Property states that:
Therefore, given the following expression:
You can simplify it by applying the properties explained before.
So, you get that following expression:
Then, you can determine that Clifton is correct.
