Find the distance between the two points in simplest radical form.

emmainna [20.7K]

The distance between the two points is $2\sqrt{5}$

Explanation:

Given that the two points are $(-8,-2)$ and $(-6,2)$

We need to determine the distance between the two points in simplest radical form.

The distance between the two points can be determined using the distance formula,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let us substitute the coordinates $(-8,-2)$ and $(-6,2)$ in the above formula, we get,

$d=\sqrt{(-6+8)^2+(2+2)^2}$

Simplifying the terms, we get,

$d=\sqrt{(2)^2+(4)^2}$

Squaring the terms, we get,

$d=\sqrt{4+16}$

Adding, we get,

$d=\sqrt{20}$

Simplifying, we have,

$d=2\sqrt{5}$

Thus, the distance between the two points in simplest radical form is $2\sqrt{5}$

AJ worked 48 hours last week. He earns $12.40 per hour plus overtime, at the usual rate, for hours exceeding 40 hours.

Romashka [77]

The answer is 595.20 because 12.40 x 48 = 595.20

Solve the boundary value problem

barxatty [35]

Another Cauchy-Euler ODE. Take $y=x^r$ and you get

$r(r-1)x^r-16rx^r+64x^r=0$
$r^2-17r+64=0$
$\implies r=\dfrac{17}2\pm\dfrac{\sqrt{33}}2$

so that the general solution is

$y=C_1x^{(17+\sqrt{33})/2}+C_2x^{(17-\sqrt{33})/2}$

With the given boundary conditions, you have

$y(1)=0\implies 0=C_1+C_2$
$y(2)=1\implies 1=C_12^{(17+\sqrt{33})/2}+C_22^{(17-\sqrt{33})/2}$
$\implies C_1=\dfrac{2^{(-17+\sqrt{33})/2}}{2^{\sqrt{33}}-1},C_2=-\dfrac{2^{(-17+\sqrt{33})/2}}{2^{\sqrt{33}}-1}$

What is the slope of the line that passes through the points (-2, 7) and (2,-5)?

Deffense [45]

Answer:

Denote that line: y = ax + b

Line passes (-2, 7) and (2,-5):

=> -2a + b =7

=> 2a + b = -5

Add both side of above equations:

=> 2b = 2

=> b = 1

=> a = (-5 - 1)/2 = -3

=> Slope a = -3

Hope this helps!
