A quadratic equation has the general form of:

y=ax² + bx + c

It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:

y = a(x+h)² - k

where h, k are the vertex points.

y=-2x^2 + 2x+ 2
y=-2(x^2 - x) + 2
y + 1/4 = -2 (x^2 -x +1/4) + 2
y = -2 (x - 1/2)^2 + 7/4

Therefore, the vertex is (-1/2, -7/4)

at x = 6, y = -58

Research by social scientists suggests that it takes ____ percent of the population of a community, country, or the world to bri

Lady bird [3.3K]

Answer:

The correct option is B) 5-10%

Explanation:

We have seen and depicted various scenarios where we see how different changes arise and dominate the world. Social scientists suggest that as low as 5-10% people of a population are enough to bring about a change because people tend to copy what others are doing. Same goes for countries of the world. Each new popular technique which is learnt by one country tends to become popular and learnt by other countries. For example, the usage of a social app starts with a few members of a population using it and with time it becomes popular in the whole world.

1. Cool, falling air is associated with __________ pressure areas.

ehidna [41]

Answer:

Cool air falls, this is associated with greater pressures areas.

Warm air rises, this is associated with low-pressure areas.

Explanation:

Due to the differences in air pressure, the wind is blown from 'one location to another location'. The cool air is denser than warm air hence the cool air fells which has high density. The warm air has less density and it rises. So the cool air is related to greater pressure areas and warm air is related to lower pressure areas.
