    How was it? Did anyone get a = 28, d = -2 and (2x - 5)(2x - 5) = 0 for the last question?
    Yes last one x=5/2

    Was the translation for the (1/5)x a reflection in the y-axis?

    Were your coordinate for the maximum (6,9) or (9,6), forgot the order.

    How did you find the perimeter of the triangle?

    Where is 1/5 from?
    EDIT: just realised 1/5 is 0.2 lols
    Also I put it was a stretch in y by scale factor 1/25 😂😂

    Yeah I missed up. Hopefully got a few marks from the 6 marks.

    if area of sector and area of shaded region were equal then area of sector was half the area of the triangle
    use area of sector to find r
    9-r for one side
    8-r for the other
    length of arc
    length of side bc
    add tgem all together
    sprry if you dont understand im not good at explaining

    (9,6)

    U worked out area of triangle so plug in the angle to get r as 5 something. Perimeter was (r x angle) + (9-r) + (8-r) + 5

    I got a= -2 and subbed it back into the integral and got 16 so I think I'm correct

    I kept getting -a +a ??? Which eliminated the a! 😡

    What did you guys get for the Binomial Expansion last part? I got a negative 4 digit number, can't remember the no. though.

    for the triangle/sector one:

    the sector = area of shaded shape

    we were given area of triangle

    so the area of the sector is 0.5*r^2*feta = A/2, which you can solve for r

    the rest is pretty much self explanatory

    2.) a) sketch the graph y = (0.2)^x [2] (graph with negative gradient and exponential shape, and asymptote of x-axis along with y-intercept marked as '1' or (0,1)
    b) something about using logs to solve for x
    c) transformation of y = (0.2)^x to y = (5)^x
    d) another transformation.
