Measure the length of the arrow in centimeters using correct significant figures.
l = 3 cm
l = 3.3 cm
l = 3.35 cm
l = 3.351 cm

The significant figures is 3.3 cm.

Explanation:

Significant :

Significant figures of a number are numbers that have significance to contribute to its resolution of measurements.

Centimeter is unit of length.

According to figure,

The significant figures is

Hence, The significant figures is 3.3 cm.

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 .
