Find a possible solution to the equation cos(x+2) = sin(3x).
A. x = 0.50
B. x = 1°
C. X= 22°
D. X= 449
|

C. x=22°

Step-by-step explanation:

Since the principles of sine and cosine are based upon right triangles, the two angles have to be complementary, adding up to 90. Thereby, in your equation, (x+2) + (3x) = 90. Combining like terms gives you:

4x + 2  =  90     subtract 2 from both sides

     - 2      -2

4x  =  88        divide both sides by 4

4         4

x   =  22      

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.
