My notes concrete sidewalks are always laid in sections, with gaps between each section. for example, the drawing shows three identical 2.4-m sections, the outer two of which are against immovable walls. the two identical gaps between the sections are provided so that thermal expansion will not create the thermal stress that could lead to cracks. what is the minimum gap width necessary to account for an increase in temperature of 44° c

the answer is false

explanation:

electrical power

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
