So 12 below zero is -12. Then we take the 54 and instead of writing the problem as 54 + (-12) (Because that's just confusing) we can write our problem as 54 - 12. 54 - 12 = 42.

The equation of a parabola is given. y=34x2−6x+15
SVETLANKA909090 [29]
The x coordinate of the vertex = -b/2a  = -(-6) / 2*34  = 0.08824

y coordinate = 34(0.08824^2 - 6(0.08824) + 15 =  14.735

so its (0.088, 14.735)     correct to 3 decimal places

777dan777 [17]

Answer with explanation:

Theorem : The diagonal of a parallelogram divides it into two congruent triangles.

Properties of parallelogram

1. Opposite sides are equal and parallel.

2. Diagonal bisect each other.

3. Opposite Angles are equal.

If you will look at the first three options

A:  Diagonals of a parallelogram bisect opposite angles.→→False(Alternate angles are equal)

B: Consecutive sides of a parallelogram are congruent.→→→False(Opposite sides are congruent)

C: Consecutive angles of a parallelogram are congruent.→→→False(Opposite angles are congruent)

D: Consecutive angles of a parallelogram are supplementary.→→→→True

For,any parallelogram, having vertices , A, B and C and D

Opposite sides are parallel, so

1.∠A + ∠B=180°

2.∠C + ∠B=180°

3.∠C+ ∠D=180°

4. ∠A + ∠D=180°

Option D
