12 Explain A bag includes one number card each for the numbers 1-25. Each of
Alex

Answer:

Let us say the domain in the first case, has the numbers. And the co-domain has the students, .

Now for a relation to be a function, the input should have exactly one output, which is true in this case because each number is associated (picked up by) with only one student.

The second condition is that no element in the domain should be left without an output. This is taken care by the equal number of students and the cards. 25 cards and 25 students. And they pick exactly one card. So all the cards get picked.

Note that this function is one-one and onto in the sense that each input has different outputs and no element in the co domain is left without an image in the domain. Since this is an one-one onto function inverse should exist. If the inverse exists, then the domain and co domain can be interchanged. i.e., Students become the domain and the cards co-domain, exactly like Mario claimed. So, both are correct!

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.
puteri [66]

Answer:

volume = 13500 cm^{3}

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid = \frac{lwh}{3}

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume = \frac{30*30*45}{3}

            = \frac{40500}{3}

            = 13500

volume = 13500 cm^{3}

The volume of the pyramid is 13500 cm^{3}.
