The surface area of Spaceship Earth is: 7850 m^2
Step-by-step explanation:
Given
Diameter of spherical structure = d = 50 meters
As the attraction is in the form of a sphere, its radius will be used to find the surface area.
The formula for surface area of sphere is:

¿Entre que números naturales consecutivos se encuentra cada raíz?
Bueno en este caso debes empezar por el 1 en adelante, pero solo sucede en números impares consecutivos. Solamente debes sumar 1,3,5,7,9,11,13,15,17,19 ..... en adelante, y en cada suma de cada sucesión encontraras un cuadrado. Ojo solo sumando en orden, tampoco sumarás 3+9, ya que te dará 12 y 12 No tiene raíz.
1+3=4,√4=2
4+5=9, √9=3
9+7=16, √16=4
16+9=25, √25=5
25+11=36, √36=6
36+13=49, √49=7
49+15=64, √64=8
64+17=81, √81=9
81+19=100, √100=10

A SI CONSECUTIVAMENTE SIEMPRE OBTENDRÁS CADA RAÍZ
¿Entre que números naturales consecutivos se encuentra cada raíz?
R= En los número impares consecutivos, comenzando por el 1 en adelante.
Yes 2/5 and 4/10 are equivalent fractions. This is because you are able to multiple both numbers in 2/5 by 2 and get 4/10. In addition, you can divide both numbers in 4/10 by 2, therefore they’re equivalent.
Answer:
-7 or 4
Step-by-step explanation:
use foil to get the quadratic equation:
x^2+5x-2x-10=18
x^2+3x-10=18
bring "18" to the left:
x^2+3x-10-18
x^2+3x-28
so what*what= -28
and
what+what=3
factors of -28: -7,4 -4,7 14,-2 -14,2 -28,1 -1,28
factors whose sum is 3: 7,-4
so substitute "7,-4" in place of 3:
x^2+7x-4x-28
2) split it in two groups
group 1) x^2+7x
group 2) -4x-28
x^2+7x has a GCF of "x"
x(x+7)
group 2) -4x-28 has a gcf of "-4"
-4(x+7)
3) (x-4) (x+7)=0
x-4=0
x=4
x+7=0
x=-7
x=4,-7
Hope this helps!
