can someone help me with this question quickly I need it by tomorrow is really confusing pleaseeee......I'm desperate

consider the equation cos^2 θ+ tan^2 θ=2

a.graphically determine a solution to the equation, to the nearest hundredth of a radian.

b.verify the solution by substitution. complete at least one verification for each set of coterminal angle...

pleaseeee help

can someone help me with this question quickly I need it by tomorrow is really confusing please......I'm desperate

1.a function is given as f(x)=9x^2+3x.

A.if f(x)=(g·h)(x), state two possible pairs of equation for g(x)and h(x).

B. if f(x)=(g o f)(x),state two possible pairs of equation for g(x) and h(x)

2.if  f={(1,4),(2,7),(3,1)}, determine (f o f)(3) and explain.

thank you for your help...

can someone help me with the question 

- For function f

-the graph of y=f(x) extends down into quadrant lll and down into quadrant IV

-the zeros of f are -2,3 and 5 

-the degree of f<5

1.what degrees is possible for f?

2.what are the maximum and minimum multiplicities possible for a zero of f?

3.two possible equations?

4.two possible graphs of y=f(x)

Consider the equation cos²x+tan²x=2

a)Graphically determine a general solution to the equation, to the nearest hundredth of a radian.

b) Verfiy the solution by substituting. Complete at least one verification for each set of coterminal angles.

A corresponding long division and synthetic division are shown

Explain why each of the following rational function scenarios is true. (Hint: Think about what the rational function would reduce to at or near the value that makes the specified factor equal to zero.)

(x+2y)^10

If the point (4,7) lies on the graph of 2y+2 = f(1/5(x-1)) what is the corresponding point on the graph of y=f(x)?
