P, Q and R are points on a circle. A tangent to the circle, RT is also shown. What is the size of angle x? Give a reason for your answer.

What is the average rate of change for this function for the interval from x=2 to x=4 ?

Write the expression as a single natural logarithm. 2 in a - 4 in y

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)
