From the mapping above it can be seen that the given relationship is bijective<span> (</span>one-to-one and onto<span> or </span>one-to-one correspondence) as e<span>ach element of the range is mapped to by </span>exactly<span> one element of the domain. So f(x)=4 implies f(2)=4 or simply x=2</span>

let x be the number you're trying to solve.

What is the volume of a certain cube? (1) The sum of the lengths of the edges of the cube is 36. (2) The surface area of the cub
german

Answer:

(1) The sum of the lengths of the edges of the cube is 36.

A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3

Volume = 3*3*3 = 27

(2) The surface area of the cube is 54.

A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)

6s^2 = 54

s = 3

Volume = 3*3*3 = 27

Step-by-step explanation:

All you need to uniquely define a cube is any one measurement - length of a side/edge, area of a surface, volume etc. If you have any one of them, you can uniquely determine the others. So each statement alone is sufficient here.

To show how,

(1) The sum of the lengths of the edges of the cube is 36.

A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3

Volume = 3*3*3 = 27

(2) The surface area of the cube is 54.

A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)

6s^2 = 54

s = 3

Volume = 3*3*3 = 27

If you wish to calculate the interest on an investment with a rate of 3.58%, what number will you plug into your equation?
irina [24]
To get a certain percentage as a decimal, all you have to do is divide this percentage by 100.

Applying this on the given question, we will find that:
3.58% = (3.58) / (100) = 0.0358

Comparing the calculated value to the given choices, we will find that the correct choice is:
<span>c) 0.0358</span>
