What is the smallest positive degree angle measure equivalent to sin^-1 (0.391)?

natta225 [31]

Given:

The value is:

$\sin^{-1}(0.391)$

To find:

The smallest positive degree angle measure equivalent to $\sin^{-1}(0.391)$ .

Solution:

We have,

$\sin^{-1}(0.391)$

Using the scientific calculator, we get

$\sin^{-1}(0.391)=23.0167366398^\circ$

$\sin^{-1}(0.391)\approx 23^\circ$

Therefore, the smallest positive degree angle measure equivalent to $\sin^{-1}(0.391)$ is 23 degrees.

Can anyone help me with this problem by factoring and list the steps please

jok3333 [9.3K]

Answer:

$m=2, m=0$

-ˋˏ✄┈┈┈┈┈┈┈┈┈┈┈┈┈

$20m^2-40m=0$

<u>Use quadratic formula:-</u>

᠃ ⚘᠂ ⚘ ˚ ⚘ ᠂ ⚘ ᠃

$m_1,_2=\frac{-(-40) -+\sqrt{x} (-40)^2-4*20*0}{2*20}$

$\sqrt{(-40)^2-4*20*0}=40$

$m_1,_2=\frac{-(-40)-,+40}{2*20}$

$m_1=\frac{-(-40)+40}{2*20},m_1=\frac{-(-40)-40}{2*20}$

$m=\frac{-(-40)+40}{2*20}:2$

$m=\frac{-(-40)-40}{2*20}:0$

$m=2, m=0$

A sphere has a radius of 6 meters. A second sphere has a radius of 3 meters. What is the difference of the volumes of the sphere

cricket20 [7]

∆volume = 4/3 *pi * (R^3 -r^3 )
= 4/3 *pi*((6)^3 -(3)^3)
= 252*pi
= 791.68 m^3
