a) Coordinates of A (1, 0), Coordinates of B (3, 0).

b) Coordinates of P (0, 3).

c) Coordinates of Q (2, -1).

Step-by-step explanation:

Step 1; The equation of the plot is y = (x -1)(x -3). So to find the values of A and B we substitute y = 0 as A and B are on the x axis which means the value of y = 0.

So x -1 = 0, x -3 = 0, So x = 1 and x = 3.

So A = (1, 0) and B = (3, 0).

Step 2; To solve for P, we substitute x = 0 as the point P is on the y axis where the value of x equals 0. So when y = (x -1)(x -3) and x = 0, the equation becomes

y = (0 -1)(0 -3) = (-1)(-3) = 3.

So the coordinate of P is (0, 3).

Step 3; The x value of the vertex of any parabola i.e. the lowest or highest point depending on the type of parabola is given by . We subtitute this value of x in y to determine the value of y.

y = (x -1)(x -3) = x² - 4x + 3. Here a = 1, b = -4 and c = 3.

x = = = = 2.

Substituting x =2 in y, we get

y = (2 -1)(2 -3) = (1)(-1) = -1.

So the coordinate of Q is (2, -1)

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
