Answer:

a = -1

Step-by-step explanation:

4a3a = (4+3)2-5 = 7a

12a = 14a - 5 = 7a

12a = 14a - 5 - 7a = 0

12a -14a + 5 + 7a = 0

(12 - 14 +7)a + 5 = 0

5a + 5 = 0

5a = -5

a = -1

i don't know if its right or not

Solve for x and y:<br><br> x+y=c<br><br> x-y=a
Lunna [17]

Answer:

x = (c+a)/2

y = (c-a)/2

Step-by-step explanation:

x+y=c

x-y=a

Add together to eliminate y

x+y=c

x-y=a

--------------

2x = c+a

Divide by 2

2x/2 =(c+a)/2

x = (c+a)/2

Multiply the second equation by -1

-x+y =-a

Add the first equation

x+y =c

-x+y=-a

-----------------

2y = c-a

Divide by 2

2y/2= (c-a)/2

y = (c-a)/2

A cube of side length s sits inside a sphere of radius r so that the vertices of the cube sit on the sphere. Find the ratio r :
svlad2 [7]

Answer:

r : s is √3 : 2

Step-by-step explanation:

The given parameter are;

A cube is inscribed in a sphere

The side length of the cube = s

The radius of the sphere = r

The ratio r : e = Required

It is noted that for a cube inscribed in a sphere, we have;

The diameter of the sphere = The diagonal of the cube

The diameter of the sphere, D = 2 × The radius = 2·r

The square of the diagonal of the cube, d² = s² + s² + s² = 3·s²

∴ The diagonal of the cube, d = (√3)·s

From the relationship between the cube and the sphere in which it is inscribed, (The diameter of the sphere = The diagonal of the cube), we have;

2·r = (√3)·s

∴ r/s = (√3)/2

r : s = √3 : 2.
