Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing four red marbles, four green ones, five white ones, and two purple ones. S
So really the question is find the minimum value of f(x) = 12 / (cosx + √3 sinx + 4)
and theres no degree sign, so Im assuming the answer should be in radians, though use degrees when explaining, cau
i have two possible solutions for the angle A in the triangle A in the triangle ABC, it is either136 or 44. the next question says given that A is an acute angle (and i know that B is an acute angle o
the isosceles triangle is A =-Let Q be the apex angle.
Draw the altitude of the triangle (bisecting the apex angle) through the center of the circle.
This altitude has length 6 + h, where h = 6 cos(Q)

I was told to find the inverse of the matrix A= ( -23, -45)(The comma separates the two rows)
So I found the determinant to be -22 and altered the matrix to : ( 5-3, 4-2)
and divided each by -22.

I wrote down some things I dont get about factoring quadratic equations...
1. When you find a common factor (when factoring) to you take the number and the letter out of the bracket, or just the numbe
Dear all,
The question is in the link below. I have done part 1 already, it was a spiral that converges on alpha.

How do I do B? I have us
3+2i
____
1-4i
i thought the answer was 11+(14i/16) but i was wrong :( any help is greatly appreciated.-(3+2i) / (1-4i)
rationalize by multiplying top and bottom by the denominators conjugate: (1+4i
1) Factor the following trinomial expression by a method of your choice: -3x2 + 5x - 2
A. (-3x + 2)(x - 1) B. (-3x - 2)(x + 1) C. (3x - 2)(x + 1) D. (3x + 2)(-x - 1)
2)Factor: x2 - 3x – 18
A. (x + 6
Im studying and Im stuck with this problem. As this isnt an algebra class, I cant remember any algebra to solve it.I know the answer is really obvious, I just cant seem to make my brain remember.

How many solutions does this equation have?
(4 sinX -√5) (sinX+1)
Here is a link to the sqa marking instructions. It is question 11. Can someone explain it in greater depth? Thanks

I know that I need to use separations of variables. After solve, how to apply the initial value?-Solve to find the general solution, then find the value of the constant:
y = 2x / (1 + 2y)
dy / dx = 2x
