Answer:

12

Step-by-step explanation:

zero of the polynomial is 2 ⇒ f(2) = 0

f(2) = 2² - 8 × 2 + k = 0

4 - 16 + k = 0

k = 12

The diagonals of quadrilateral ABCD intersect at E (2,5). ABCD has vertices at A (3,7) and B (3,6). What must be the coordinates
Ivahew [28]

Answer:

C(1,3) and D(1,4).

Step-by-step explanation:

The given quadrilateral ABCD has vertices at A (3,7) and B (3,6). The diagonals of  this quadrilateral ABCD intersect at E (2,5).

Recall that, the diagonals of a parallelogram bisects each other.

This means that; E(2,5) is the midpoint of each diagonal.

Let C and D have coordinates C(m,n) and D(s,t)

Using the midpoint rule:

(\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2})

The midpoint of AC is (\frac{m+3}{2}, \frac{n+7}{2})=(2,5)

This implies that;

(\frac{m+3}{2}=2, \frac{n+7}{2}=5)

(m+3=4, n+7=10)

(m=4-3, n=10-7)

(m=1, n=3)

The midpoint of BD is (\frac{m+3}{2}, \frac{n+7}{2})=(2,5)

This implies that;

(\frac{s+3}{2}=2, \frac{t+6}{2}=5)

(s+3=4, t+6=10)

(s=4-3, t=10-6)

(s=1, t=4)

Therefore the coordinates of C are (1,3) and D(1,4).
