Answer: 120 degrees, the total is 720 degrees, so that divided by 6 is 120
The equation of a circle is given as:
(x-a)^2 + (y- b)^2 = r^2 where (a, b) is the center.
(x-9)^2 = x^2 -18x + 81 - ----(i)
(y+2)^2 =y^2 + 4y +4 ------ (ii)
r^2 = 49 ------ (iii)
Adding equation (i) and (iii)
x^2 + y^2 - 18x + 4y + 85 -----(iv)
Equating equation (iv) and (iii)
<span>x^2 + y^2 - 18x + 4y + 85 = 49
Arrange the equation:
</span> <span>x^2 + y^2 - 18x + 4y + 36 = 0
</span><span>

Answer:
7
Step-by-step explanation:
Total number of surfaces of cube are 6.
Each surface is square.
And area of square is (side)^2
That means, total surface area will be 6 * (side)^2
From question,
294 = 6 * (side)^2 ( Surface area given)
=> 294 ÷ 6 = ( side) ^2
=> 49 = side^2
=> √49 = side
=> 7 = side
So, length of edge of cube is 7
The differnce of 2 perfect cubes
remember
a³-b³=(a-b)(a²+ab+b²)
so
Respuesta:
h = V / 15
Explicación paso a paso:
El volumen de un prisma rectangular se calcula usando la relación:
Largo ancho alto
Donde, largo y ancho son la dimensión de la base
Por eso,
Volumen = Base * altura
Volumen = (5 cm * 3 cm) * altura
De la pregunta, no se da el volumen, por lo tanto, tomamos el volumen como V en otro para calcular la altura, h
V = 15h
Divide ambos lados entre 15
V / 15 = 15h / 15
V / 15 = h
