Find the vertex of this parabola.

Mathematics

Rashid [163]3 years ago
4 0

Answer:

The vertex of this parabola is (1, 14).

Step-by-step explanation:

To find the vertex of this parabola, one approach is to determine the equation of the axis of symmetry:  evaluate x = -b / (2a), where a, b and c are the coefficients of the x^2, x and x^0 terms respectively.

Here a = -2, b = 4 and c = 12.

Thus, the axis of symmetry is x = -4 / (2· -2), or x = 1.

The function value at x = 1 is   y = -2(1)^2 + 4(1) + 12, or  y = -2 + 4 + 12 = 14.

The vertex of this parabola is (1, 14).

Look at the picture and read the question. I think the answer is 137 degrees but I don't know how to get it. I need help lol. Th

Answer:

That is a parallelogram so that opposite angles are equal.

10x -27  = 2x + 29

x = 7

and therefore those angles equal 43 degrees each

It is a parallelogram, so

angle V + W +X + Z = 360

we know that angle Y + angle W = 2 * 43 = 86 degrees

angle V + angle X = 360 -86 degrees

angle V + angle X = 274 degrees

angle V = 274 / 2 = 137 degrees
