If θ is a first-quadrant angle in standard position with P(u, v) = (3, 4), evaluate cos 2 θ . -7/25 -1/5 7/25
Grace [21]

Answer:

-7/25.

Step-by-step explanation:

From the given point P we see that the hypotenuse =  √(3*2 + 4^2) = 5.

So cos  θ = 3/5

cos 2 θ =  2 cos^2 θ - 1

= 2 * (3/5)^2 -1

= -7/25.

Solve quadratic equation x²-8x-1=0 by formula method​
Alex_Xolod [135]

Answer:

x²-8x-1=0

comparing above equation with ax²+bx+c=0

a=1

b=-8

c=-1

x=

x =  \frac{ - b +  -  \sqrt{ {b}^{2} - 4ac } }{2a}

=(--8+-√(64-4×1×-1)/2×1

=8+-√(64+4)/2

taking positive

x=(8+√68)/2=2(4+√17)/2=4+√17

taking negative

x=(8-√68)/2=2(4-√17)/2=4-√17

identify a transformation of the function f(x) = √x by observing the equation of the function g(x) = √x-2
gregori [183]
<h2>Answer:</h2>

f(x)=\sqrt{x} is the Square Root Function. These are the characteristics of the graph of the square root function:

  • The domain of the function is the set of all non negative real numbers.
  • The range of the function is the set of all non negative real numbers.
  • The graph has an intercept at (0,0).
  • The graph is increasing on the interval (0, \infty).

Since the function g(x)=\sqrt{x}-2, then this stands for the form:

g(x)=f(x)-c. This form tells us that the graph of f has been shifted c units downward where the value c = 2 in this problem. The graphs of both functions are shown below. The red one is f(x) while the blue one is g(x)
