A boy found a bicycle lock for which the combina- tion was unknown. The correct combination is a four-digit number, d1d2d3d4, wh

ere di, i = 1, 2, 3, 4, is selected from 1, 2, 3, 4, 5, 6, 7, and 8. How many different lock combinations are possible with such a lock?

Answer:

4096 possible combinations

Step-by-step explanation:

If a experiment can takes place in forms n1, then a second experiment can takes place in forms n2, ... , then a i-experiment can takes place in ni forms finally the number of possibilities to carry out the entire experiment are :

n1 x n2 x ... x ni

This is call the multiplication principle.

In our experiment (finding a four - digit number)

d1 can be chosen between 1,2,3,4,5,6,7,8

d2 can be chosen between 1,2,3,4,5,6,7,8

.

.

.

d4 can be chosen between 1,2,3,4,5,6,7,8

The lock combinations are d1 x d2 x d3 x d4 = 8 x 8 x 8 x 8 = 8^4 = 4096

Please explain how you find the slope of a graph? Please explain with photos.

☁️ Answer ☁️

Here's what I found:

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Check your result using the slope calculator.

To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.

Find the volume of the cone.
Murrr4er [49]

\qquad\qquad\huge\underline{{\sf Answer}}♨

Volume of cone :

\qquad \sf  \dashrightarrow \: \frac{1}{3}   \pi{r}^{2} h

Now, let's plug in the values as per the diagram ~

\qquad \sf  \dashrightarrow \: \frac{1}{3}    \times 3.14 \times {(18)}^{2}  \times 10

\qquad \sf  \dashrightarrow \: \frac{1}{3}    \times 31.4 \times 324

\qquad \sf  \dashrightarrow \:   31.4 \times108

\qquad \sf  \dashrightarrow \:3391.2 \:  \: ft {}^{3}

6х + 7 = 4х + 13 Solve for X​
N76 [4]

Answer:

x = 3

Step-by-step explanation:

subtract 7 from both sides, then subtract 4x from both sides after

6x +7 = 4x + 13

     -7              -7

6x = 4x +6

-4x   -4x

2x = 6

divide both sides by 2x

answer x =3
