Answer:

Sort the list first, then do a bisection search

Explanation:

In bisection search method, we divide the array of numbers in two equal parts. Then we check that the number is exist in first half or second half. It is necessary to perform this operation that array should sorted. This is the fast searching algorithm as compared to Linear search. In linear search Algorithm we have to check every element in the array until we find the required number. The bisection search method is faster as compare to linear search. This follows following steps top complete the operation of searching.

  1. Sort the array
  2. Divide the total array in two equal parts
  3. Check that the required number that we want to search is in first half or second half
  4. If the number is found in first half then second half of array will be discarded.
  5. Then repeat step 2 and 3 until not found the required element.

Semenov [28]

Answer:

Functional Family Therapy

Explanation:

According to my research on different types of therapies, I can say that based on the information provided within the question the therapy being described in this scenario is called Functional Family Therapy. This is a type of therapy aimed at young teens roughly aged 11-18 who are exhibiting violent or negative behaviors and/or substance abuse. The therapist sits down with the child, their parents, and sometimes an officer of the law in order to get to the root of the problem and come up with different solutions that may help the child feel less angry and prone to act out.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance
lesantik [10]

Answer:

In C:

#include <stdio.h>

#include <math.h>

int main(){

   float f0,r,temp;

   r = pow(2.0,1.0/12);

   printf("f0: ");    scanf("%f", &f0);

   temp = f0;

   for(int i = 0; i<=4;i++){

       f0 = f0 * pow(r,i);

       printf("%.2lf ", f0);

       f0 = temp;    }

   return 0;

}

Explanation:

This declares f0, r and temp as float

   float f0,r,temp;

This initializes r to 2^(1/12)

   r = pow(2.0,1.0/12);

This prompts the user for f0

   printf("f0: ");    scanf("%f", &f0);

This saves f0 in temp

   temp = f0;

This iterates the number of keys from 0 to 4

   for(int i = 0; i<=4;i++){

This calculates each key

       f0 = f0 * pow(r,i);

This prints the key

       printf("%.2lf ", f0);

This gets the initial value of f0

       f0 = temp;    }

   return 0;

Y'+2y = 5-e^(-4x), y(0)=-11
Anastaziya [24]

Answer:

  see attached

Explanation:

A differential equation solver says the exact solution is ...

  y = 5/2 -14e^(-2x) +1/2e^(-4x)

The y-values computed by Euler's method will be ...

  y = ∆x·y' = 0.1(5 - e^(-4x) -2y)

The attached table performs these computations and compares the result. The "difference" is the approximate value minus the exact value. (When the step size is decreased by a factor of 10, the difference over the same interval is decreased by about that same factor.)
