The gravitational attraction betweentwo bodies varies inversely as thesquare of the distance between them.If the force of attrac

Sliva [168]

The force for the case 1 is 64 pounds and the distance is 9 feet, it is:

$\begin{gathered} \frac{k}{9^2}=64 \\ k=5184 \end{gathered}$

Now, if the force is 36 pounds, let solve for the distance:

$\begin{gathered} \frac{k}{r^2}=36 \\ \frac{5184}{r^2}=36 \\ r^2=144 \\ r=12 \end{gathered}$

Hence the answer is 12 feet.

< J and < M are base angles of isosceles trapezoid JKLM. If measure < J = 20x +9 and m < M= 14x +15, find measure &l

Kazeer [188]

The base angles of an isosceles trapezoid are equal. Therefore:
20x + 9 = 14x + 15
6x = 6
x = 1
So, the base angles both equal 29 degrees.
In a trapezoid, the sum of the angles attached to the same leg always = 180 degrees.
Therefore, angle K and angle L equal 151 degrees.

Find an equation for these points (-5,5) (4,2)

user100 [1]

Answer:

$\large\boxed{y=-\dfrac{1}{3}x+\dfrac{10}{3}}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (-5, 5) and (4, 2).

substitute:

$m=\dfrac{2-5}{4-(-5)}=\dfrac{-3}{9}=-\dfrac{1}{3}$

Put the value os a slope and coordinates of the point (4, 2) to the equation of a line:

$2=-\dfrac{1}{3}(4)+b$

$2=-\dfrac{4}{3}+b$ <em>add 4/3 to both sides</em>

$2\dfrac{4}{3}=b\to b=3\dfrac{1}{3}\to b=\dfrac{10}{3}$
