I meant sine graph instead of sign graph. So what do I do? Should I set the denominator to greater than or equal to zero and solve? I tried solving using the above method but I think my math is wrong. Nonetheless it is wrong because my teacher wants a sine graph on a number line... 1)...

Homework Statement Find the domain of the function. You will need a sign graph. Answer in interval notation. Homework Equations f(x)= (3)/[(x2-4x)1/2] The Attempt at a Solution No clue - I don't know how to use a sign graph or what the positive/negative results mean as solutions on a number line.

I have no idea what I did wrong- please let me know. I don't know what each angle is equal to either.

Homework Statement An airliner is flying in the direction North 20 degrees East with an airspeed of 300mph. Its ground speed and true course are 350mph and 30 degrees respectively(RESULTANT). Use a vector analysis to determine the direction and speed of the wind. Include a diagram.Homework...

Homework Statement This is more of a math question - I just want to know how I can find the value of t when v=0. 0=5(t3/2)-(27/2)(t^1/2)+9(t^-1/2)Homework Equations The Attempt at a Solution I do not know how to solve this. Please show steps. Thanks.

Homework Statement 1) Solve the equation using the exponential form of the equation. Log2(2-5x)=7 2) Rewrite as a single logarithmic expression: 3log x +(1/2)log z Homework Equations The Attempt at a Solution 1) I have no idea how to solve this. 2) I know that two logarithms multiply to...

Homework Statement Given p(x)=x2-5x and q(x)=x-5: 1) Find (p+q)(x) and (p/q)(x) 2) Find (p o q)(x) and (p o q)(-3) (I did this correct I think) Homework Equations The Attempt at a Solution 1) I am thinking this is just (x2-5x+x-5) and (x2-5x)/(x-5). Is this correct...

Homework Statement Y1=(x3+3x2-4)/(x2)Homework Equations Slant Asymptote at y=x+3. (X-1) and (X+2) appear to be intercepts in the back of the book. How do I factor the numerator to get that?The Attempt at a Solution I know this is simple and there is a method to find the zeros of the numerator...

A goat rancher is going to fence off a rectangular pen in the middle of a large open area. Build an equation to help determine the maximum area (to the nearest sq ft) that can be fenced off if 1200 ft of fencing is avilable. Include a diagram as a part of your solution.

Someone please help here this is due tomorrow morning- thanks.

PROBLEM #24- A goat rancher is going to fence off a rectangular pen in the middle of a large open area. Build an equation to help determine the maximum area (to the nearest sq ft) that can be fenced off if 1200 ft of fencing is avilable. Include a diagram as a part of your solution.) I have...

Got it, thanks! :) Answer my next thread please- lol.

Got it, thanks.

Homework Statement Sketch the graph of each function given using shifts and stretches of the parent function y=x2 (not by simply plotting points). Clearly indicate and explicitly state the orientation, vertex, axis of symmetry, y-intercept, and point symmetric to the y-intercept, the...

Homework Statement f(x)=x3-3x2-6x+8 Homework Equations p/q=+-(1,2,4,8) f(0)=8 The Attempt at a Solution What is the fastest way to find the zeros? I have to graph it. The back of the book shows the zeros looking to be 4, -2, and most likely 1.5. I am assuming we use the rational...
