Answer:
Step-by-step explanation:
Using the Pythagorean identity
sin²x + cos²x = 1, then
sin²x = 1 - cos²x
sinx = 
note that cosΘ = 
= 
sinΘ = 
= 
= 
=
Can't take the square root of a negative so find a domain where it takes squaer root of 0 wich is allowed hold a sec
there
the denomenator can't be 0 so x cannot be 3, it has to be greater
Answer:
b. 1/2
Step-by-step explanation:
lim (x -3)(x +2)
x-->-∞ ---------------
2x^2 + x +1
= lim (x^2 -3x +2x - 6)
x-->-∞ -----------------------
2x^2 + x +1
= lim (x^2 -x - 6)
x-->-∞ -----------------------
2x^2 + x +1
When we plug in x = -∞, we get indeterminate form.
Now we have to use the L'hospital rule.
d/dx (x^2 - x - 6) = 2x -1
d/dx (2x^2 + x + 1) = 4x + 1
Now apply the limit
lim (2x - 1) / (4x + 1)
x--->-∞
Here we have to degree of the numerator and the denominator of the same. In this case, if x --> -∞, we get the result as the coefficient of the leading term as the result.
According to the rule, we get
= 2/4
Which can simplified as 1/2
The answer is 1/2
Hope this will helpful.

Answer:
C.255
Step-by-step explanation:
To find the answer to this question, we can 14 by 5 and subtract it from the total of 325.
14*5=70
