How many ways can we write a list of 6 numbers from (1, 2, 3, 4, 5, 6, 7, 8) without repeating any?
Explanation:
[tex] \binom{n}{\\ k} = \binom{6}{8} = \frac{8 \times 7 \times 6 \times 5 \times 4 \times 3}{6 \times 5 \times 4 \times 3 \times 2} = 28[/tex]
We divide by factorial of 6 (!6) what is 6×5×4×3×2×1 so that there is no repetition.
Answer:
Explanation:
Number of combinations:
[tex]C_{8}^6 = \frac{8!}{(8-6)!*6! } = \frac{6!*7*8}{2!*6! } = \frac{7*8}{1*2} = \frac{56}{2}=28[/tex]
in python Simple geometry can compute the height of an object from the object's shadow length and shadow angle using the formula: tan(angleElevation) = treeHeight / shadowLength. Given the shadow length and angle of elevation, compute the tree height.
Sample output with inputs: 0.4 17.5
Tree height: 7.398881327917831
Answer:
import math
angle = float(input('Enter Angle: '))
shadowLength = float5(input('Enter Shadow Length: '))
tree_height = math.tan(angle)*shadowLength
print('Tree Height = {}'.format(tree_height))
Explanation:
From the equation given, the first step is to derive the equation for calculating the Tree Height.
In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.
The program then prompts the user to input values for angle and shadow length.
The inputted values are converted to floats and used in the equation that was derived for Tree height.
Three height is evaluated and the result is printed to the screen

Identify two uses of 3D printing that help doctors and patients in hospitals.
Answer: Prosthetic and Diagrams
Explanation:
Prosthetics are made by 3D printing, used as a new stand in for a missing limb. Like if you were to loose a leg or an arm, 3D printing creates the outer shell most times. Diagrams are used to show examples to patients of their condition, or even sometimes for other doctors to get a better understanding of a condition. They may show them to patients to give an example of what may need to happen too. For doctors they may also be used to figure out what plan of action may be needed.

Assume that x, y, and z are int variables. Write a statement using the conditional operator (? :) that compares the values of the variables x and y. The value of the larger of the two variables should be assigned to z.
The statement using the conditional operator (? :) that compares the values of the variables x and y will be:
public class Main {
public static void main(String[] args) {
int x = 10;
int y = 20;
int z = (x > y) ? x : y;
System.out.println("z = " + z);
}
}
How to illustrate the information?The ternary conditional operator (?:) has three operands and accepts them all. A boolean expression that can be evaluated as true or false makes up the first operand. The second operand is executed if the boolean statement evaluates to true. The third operand is executed if the boolean expression returns false.
It should be noted that because 10 is not greater than 20, the boolean statement (x > y) in this program evaluates to false. As a result, the third operand (y) is executed, and z is given the value of y (20).

Answer:
z = (x > y) ? x : y;
Explanation:
The conditional operator in C++ is the "? :" operator. This operator checks a condition and then returns one of two values, depending on whether the condition is true or false. The syntax for the conditional operator is:
(condition) ? value_if_true : value_if_false;
z = (x > y) ? x : y; checks if the value of x is greater than y. If it is, then the value of x is assigned to z. If it is not, then the value of y is assigned to z.

What is the purpose of a frame check sequence (FCS) footer?
Answer:
Frame check sequence (FCS) refers to the extra bits and characters added to data packets for error detection and control.
Explanation:
Network data is transmitted in frames. Each frame is comprised of bits of data appended to the header, which holds basic information such as source and destination media access control (MAC) addresses and application. Another set of characters is added to the end of the frames, which are checked at the destination. Matching FCSs indicate that delivered data is correct.

A network switch transmits data packets from one computer network to another computer network.
What is a network switch?A network switch connects devices in a network (such as computers, printers, and wireless access points) and allows them to 'talk' by exchanging data packets.
Switches can be both physical hardware devices that manage physical networks and software-based virtual devices.
A router is significantly more advanced and sophisticated than a switch. They can perform Network Address Translation (NAT), make faster routing decisions, and use routing algorithms to route data across large networks.
Routers connect multiple LANs, whereas switches operate within a single LAN.
A network switch connects and transmits data packets to and from local area network devices (LAN).
