Answer:

The radius of the circle with circumference 22cm is 3.5 cm

Step-by-step explanation:

The circumference of circumference of a circle is the distance of its closed boundary.

The circumference of a circle with radius r is given by the formula:

$C = 2\pi r$

Given

C = 22cm

Putting the values in the formula

$22 = 2 * \frac{22}{7} * r\\22 = \frac{44}{7} * r\\r = \frac{7}{44} * 22\\r = \frac{7}{2}\\r = 3.5cm$

Hence,

The radius of the circle with circumference 22cm is 3.5 cm

We say a function f: A -> B is injective (one-to-one) iff for all xE A, r2A, f(x1) = f(x2) implies r = r2. What does it mean

san4es73 [151]

Answer:

By definition a function $f:A\rightarrow B$ is injective if and only if $f(x_1)=f(x_2)$ implies $x_1=x_2$ . Notice that this means that different elements of the domain have different images. That is why injective functions are also called one-to-one, because each element from A has only one image in B.

Now, if a function is not injective means that there are, at least, two elements of the domain with the same image. A very good example is the function $f(x)=x^2$ . Recall that $f(-1) = (-1)^2=(1)^2=f(1)$ .

For real functions of a real variable $f:\mathbb{R}\rightarrow\mathbb{R}$ we have a geometrical interpretation of injective property. The function $f$ is injective if for each line we draw parallel to the X-axis, it has, at most, one intersect with the graph of $f$ . Then, if one line has more than one intercept, then the function is not injective.
