From the question, we know that
(x₁,y₁) = (4,5)
(x₂,y₂) = (8,9)

Find the slope of the line with the formula of slope
m = $\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Input the numbers
m = $\cfrac{9-5}{8-4}$
m = 4/4
m = 1
The slope of the line is 1

Using this formula, determine the line equation
y - y₁ = m(x - x₁)

Input the numbers
y - 5 = 1(x - 4)
y - 5 = x - 4
y = x - 4 + 5
y = x + 1
The correct answer is first option

I am Lyosha [343]

Answer:

238.40

Step-by-step explanation:

you need to use "PRT"( Principal× Rate×time) but since it doesn't give us the time, we'll be only doing principal×rate. just multiply 596 and 40% And don't forget to put the percent sign bc it would change the price!! and I hope that helps u

Find r(t) if r'(t) = 5t4i + 6t5j + t k and r(1) = i + j.

Vladimir [108]

$\mathbf r(t)=\displaystyle\int(5t^4\,\mathbf i+6t^5\,\mathbf j+t\,\mathbf k)\,\mathrm dt$
$\mathbf r(t)=(t^5+C_1)\,\mathbf i+(t^6+C_2)\,\mathbf j+\left(\dfrac12t^2+C_3\right)\,\mathbf k$

Given $\mathbf r(1)=\mathbf i+\mathbf j$ , we have

$\begin{cases}1^5+C_1=1\\\\1^6+C_2=1\\\\\dfrac121^2+C_3=0\end{cases}\implies C_1=0,C_2=0,C_3=-\dfrac12$

so that the particular solution is

$\mathbf r(t)=t^5\,\mathbf i+t^6\,\mathbf j+\dfrac12(t^2-1)\,\mathbf k$

What is programming?

Program is the set of instructions given to the computer so that the computer can execute those instructions. The act of writing program is called programming.

The program has been shown below

#include<stdio.h>

using namespace std;

int main()

{

double n1, n2, n3;

double s;

printf("Enter first numbers");

scanf(%lf, &n1);

printf("Enter second numbers");

scanf(%lf, &n2);

printf("Enter third numbers");

scanf(%lf, &n3);

s = n1 + n2 + n3;

printf("Sum = %f", s);

return 0;

}

6 runners, 3 medals, how many ways to give them? well, runner say 2 could get gold or not, bronze or not and silver or not, and so can any other runnner, and the order "does matter", it makes a distinction, thus, is a Permutation

$\bf _nP_r=\cfrac{n!}{(n-r)!}\qquad \qquad _6P_3=\cfrac{6!}{(6-3)!}$
