Decimal - 1.6 fraction - 1 3/5
Answer:
the answer I believe will be 25.16
Given function is
Now we have to find which inequality can be used to find the domain.
Given function is a square root function. We know that square root function is defined only for the positive values including 0. In other words expression inside the square root must be greater than or equal to 0.
In given problem, expression inside the square root is (5x-5) so that must be greater than or equal to 0 which can be written as :
which is same as your answer.
Hence your answer is correct.
Answer:

sin(x)= -3/5, x is in third quadrant
In right angle triangle ,
Opposite side of angle x = -3
Hypotenuse = 5
Now we find out adjacent side of angle x so that we can find out cosx
We use pythagorean theorem
25 = 9 +x^2
x^2 = 16, so x= 4
adjacent side = 4
cos (x) =
Cos is negative in third quadrant so cos(x) =
Now we use double angle formula
=
Tan is positive in third quadrant so final answer is
