Determine whether f is a function from the set of all bit strings to the set of integers if

1 answer:

7 0

$f$ is not a function because for a given string it can return more than one possible value. For example, if $s=010$ , then $f(s)\in\{1,3\}$ .

Solve this and get 12 points

Pachacha [2.7K]

Answer:

Step-by-step explanation:

First, find x. Since x is the average of the three number, add the three up and then divided by three. Thus:

$x=\frac{13+-16+6}{3}=3/3=1$

y is the cube root of 8. Thus:

$y=\sqrt[3]{8}=2$

So:

$x^2+y^3\\=(1)^2+(2)^3\\=1+8=9$

What is the volume of this square pyramid?

tatuchka [14]

Answer: 1296 cm³

Step-by-step explanation:

Since, the volume of a square pyramid is,

$V = \frac{a^2h}{3}$

Where a = side of the square base,

h = height of the pyramid,

By the given diagram,

a = 18 cm,

h = 12 cm,

Hence, the volume of the given pyramid,

$V = \frac{18^2\times 12}{3}$

$= \frac{324\times 12}{3}$

$=\frac{3888}{3}$

$=1296$ cube cm.

⇒ First option is correct.

The steps below show the incomplete solution to find the value of x for the equation

mafiozo [28]

Step 1: 6x - 2x - 5 = -6 + 21
Step 2: 6x - 2x - 5 = 15
Step 3: 4x - 5 = 15

The next step would be to add 5 to both sides of the equation.
so Step 3: 4x - 5 = 15 .......add 5 to both sides would make
Step 4: 4x = 20

So after the next step you would have 4x = 20

Hope this helps! :)
