In the vicinity of a bonfire the temperature t (in °c) at a distance of x meters from the center of the fire is given by t(x)=5/(x^2+400). at what range distances from the fire's center is the temperature less than 210°c?

The neighborhood is indeed the region as well as the nearest stuff. These same four blocks around a building and all the stores and items in that four-block range are examples from the immediate area, and the further calculation can be defined as follows:

Given:

Calculating the x value:

Temperature is less than 210°C at distances of more than 44.51 meters.

  distances greater than about 44.51 m

Step-by-step explanation:

We want to find x such that ...

At distances greater than 44.51 meters, the temperature is less than 210 °C.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
