Mathematics
1 answer:
xenn [34]3 years ago
5 0

Answer:

5×10^9

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

5×10^9

alexandr402 [8]
(3x^2 - 2x + 12) + (x^2 + 8x -2)

A parabola has a vertex at (-1,0) and opens down. What is the equation of the parabola?
Lapatulllka [165]

Answer:

y = - (x + 1)²

Step-by-step explanation:

Vertex form of a parabola is given by,

y = -(x - h)² + k

Where (h, k) is the ordered pair representing vertex.

(-) sign denotes that the parabola is opening downwards.

If the coordinates of the given parabola is (-1, 0)

Equation of the parabola will be,

y = - (x + 1)² + 0

y = - (x + 1)²

Therefore, equation of the parabola will be, y = - (x + 1)²
