F=gMv^2/r solve for v

neonofarm [45]

First multiply the equation by r
f*r=(mv^2)
then divide by m f*r/gm=v^2
put the equation all together you get v=sqrt(FrgM)/gM

Which equation correctly uses point (–2, –6) to write the equation of this line in point-slope form? Y – 6 = y minus 6 equals St

GenaCL600 [577]

Answer:

Part 1) $y+6=\frac{2}{5}(x+2)$

Part 2) $y+6=\frac{5}{2}(x+2)$

Step-by-step explanation:

The equation of the line in point slope form is

$y-y1=m(x-x1)$

we're going to analyze two cases

<em>First case</em>

$Point\ (-2,-6)$

$slope\ m=\frac{2}{5}$

substitute

$y+6=\frac{2}{5}(x+2)$

therefore

y plus 6 equals StartFraction 2 Over 5 EndFraction left-parenthesis x plus 2 right parenthesis

<em>Second case</em>

$Point\ (-2,-6)$

$slope\ m=\frac{5}{2}$

substitute

$y+6=\frac{5}{2}(x+2)$

therefore

y plus 6 equals StartFraction 5 Over 2 EndFraction left-parenthesis x plus 2 right parenthesis

Find a. Round to the nearest tenth:

Ulleksa [173]

Step-by-step explanation:

In the following triangle, a= ? , b= 2cm.

m<B= 105° , m<C = 15° ,m< A =?

Now, we know that sum of the interior angles of the triangle = 180°

m<B+m<C +m< A =180°

105°+15°+m< A=180°

m< A= 180- 120° = 60°

$\frac{ \sin( A) }{a} = \frac{ \sin(B) }{b}$

$\frac{ \sin(60) }{a} = \frac{ \sin(105) }{2}$

$a = \frac{ \sin(60) }{ \sin(105) } \times 2$

$a = 1.79$

$a = 1.8$
