I solved the problem myself. :o 2 linear equations are needed.

How many linear equations are needed to find the constraints in the polynomial when modelling data that has been found to follow a linear function?" The question seems way too wordy in itself and I have not been able to find anything useful in my textbook or external resources. Can...

It's cube-root x.

I know, and I'd rather understand how to do the work instead of just getting answers! I know how to find the inverses of functions, but I've never done it in a composition function.

Alright. But I don't really understand how to do the second question. The thing is that I have to be done this question within the next 20 minutes because my tutor is only going to be available for a little bit today. :(

1! So it is (0,1)?

That's 0.

I thought it was (0,1), but I'm not sure.

This question is killing me. I'm finding it difficult to do and it's a problem with my homework. Given that $$f(x)=2x^2-x+1,\,g(x)=2\sin(x)\text{ and }h(x)=3^x$$, determine the following. You need not simplify the expressions. $$f(g(-\pi))=?$$ $$\left(h^{-1}\circ f \right)(x)=?$$...

OK, so I followed what you said and got this: A = (0.5)(r)^2(θ) = (0.5)(1)^2([√3]/2 x 2) = (√3)/2 units Is this correct?

My apologies, I've never done a question like this before and I don't see anything from my notes or previous questions that resembles something along these lines. So I am going to guess that I have to do this: > Divide area of entire circle by 2 > Divide segments by 2 both times (because the...

OK, then. But the height of the triangle AOB is still 1/2, am I correct? I have gotten this: Area of Circle A = (pi)(r)^2 = (pi)(1)^2 = (pi) units Area of Triangle AOB A = (BxH)/2 = (√3 x 0.5)/2 = (√3)/4 units So I would subtract the Area of the Triangle AOB from the Area of the Circle, and I...

Alright, I managed to answer my own question. OA and OB are identical. But how can I find the radius of the circle? I guess that is basically what the entire issue is, seeing as how I cannot get the radius from the diagram (I think). Thanks in advance!

Thanks for the reply! So would OA be identical to OB, then?

Hi again, I'm completing my tutoring booklet for trigonometry and I have a question that is quite difficult. I've never done anything like it and my solutions page only has the final answer. I'd like to see how the result is found step-by-step, so if anyone can help me out or at least guide me...
