J\alpha gv
j=agv where a is a constant of proportionality.
j=1 when g=4 and v=5
1=a*4*5
1=20a
a=1/20
a= 0.05
j=0.05gv
When g=10 and v=9,
j=0.05*10*9
j=0.5*9
j=4.5

Como se calcula la medida de la sircunferencia si conocen la medida del diámetro
anygoal [31]
Para encontrar la medida de la circunferencia se aplica la ecuación P = π*D.

Explicación.

El perímetro es la medida total de todos los lados que pueda tener una figura geométrica, además se tiene que tener en cuenta que es una magnitud fundamental de los polígonos.

Para una circunferencia el perímetro se encuentra multiplicando el diámetro y el número π (pi), como se muestra a continuación:

P = π*D

Dónde:

P es el perímetro.

D es el diámetro

If sin theta = -5/7 , which of the following are possible?
Sav [38]

Solution:

we are given that

sin \theta=-5/7

As we know that

cos \theta =\sqrt{1-sin^2 \theta}  \\

Substitute the value we get

cos \theta=\sqrt{1-(\frac{-5}{7})^2}  \\
\\
cos \theta=\sqrt{1-(\frac{25}{49})}  \\
\\
cos \theta=\sqrt{(\frac{24}{49})} =\frac{\sqrt{24}}{7}\\

Since sec \theta=\frac{1}{cos \theta}\\

So here sec \theta=\frac{7}{\sqrt{24}}\\

As we know that

tan \theta=\frac{sin \theta}{cos \theta}\\
\\  \text{Substitute the values we get}\\
\\
tan \theta=\frac{-5/7}{\frac{\sqrt{24}}{7}}\\
\\
tan \theta=\frac{-5}{\sqrt{24}}\\

Hence the correct option is C.
