No, she's no good at math...
2.99/6 = about fifty cents a drink.
9.4 is the distance coming back with pythagorean theorem
add the original 13 miles
22.4 miles
Hello,
Since 3sin x-4sin^3x=sin (3x) (*****)
3sin x-4sin^3x=-1
==>sin (3x)=-1
==>3x=3π/2 +2kπ
==>x=π/2+2kπ/3, k being an integer
(*****)
sin (3x)=sin(x+2x)=sin x cos2x+cos x sin 2x
=sin x(cos²x-sin²x)+2cos²x sin x
=sin x(cos²x+2cos²x-sin²x)
=sinx(3(1-sin²x)-sin²x)
=3sin x-4sin^3x
The first missing quantity is force due to gravity, and it is 215.1 N.
The second missing quantity is distance between the statellite and the Earth, determined as 6,000 km.
<h3>
Force between two masses</h3>
The force between two masses is determined by applying Newton's law of universal gravitation as shown below;

where;
- M is mass of Earth = 5.97 x 10²⁴ kg
- m is mass of the satellite
- R is the distance between the satellite and the Earth
- G is universal gravitation constant
<h3>First missing quantity</h3>
The first missing quantity is force due to gravity, and it is calculated as follows;

<h3>Second missing quantity</h3>
The second missing quantity is distance between the statellite and the Earth,
