ANSWER
The points are:
(32,-85)
and

EXPLANATION
The given parametric equation that defines the curve is:


We differentiate to get,


The slope of the tangent is given by;


For the slope to be 1, then we must solve the following equation for t.






When t=-2, we put -2 into the expression for x and y to get
x=4(-2)³ and y=3+40(-2)-2(-2)²
This implies that,
x=32, y=-85
Hence one point is (32,-85)
Similarly, when


Another point is

The side opposite the lasrgest angle will also be the largest side in the triangle
Here it s 5.5 cms.
so using the given ratios we have
2/11 = x /5.5 where x is the smallest side (opposite the smallest angle)
x = (2*5.5) / 11 = 1 cm.
8 = 8v - 4 (v + 8)
Distribute the 4 through the parentheses
8 = 8v - 4v - 32
combine like terms
8 = 4v - 32
add 32 to both sides
8 + 32 = 4v -32 + 32
combine like terms
40 = 4v
divide each side by 4
40/10 = v
4 = v
v= 4
<u>Solution</u><u>:</u>
The rationalisation factor for
is 
So, let us apply it here.

The rationalising factor for 5 - √2 is 5 + √2.
Therefore, multiplying and dividing by 5 + √2, we have
