Complete question :
Tim used the expression below, n³ where n represents side length, to determine the volume of a cube. Using this
expression, what is the volume of a cube with side length 3.5 inches? Show your work.
n?
Answer:
42.875 cubic inches
Step-by-step explanation:
Given that :
The formula to obtain the volume of a cube is n³ ; where n = side length of the cube.
The side length of a certain cube is given as = 3.5 inches.
The volume of the cube is calculated thus :
Volume = n³ = 3.5³
Volume = (3.5 * 3.5 * 3.5) inch³
Volume = 42.875 in³
Answer:
The center is at (0,0)
The vertices are at ( (
±2 sqrt(2),0)
foci are (
±sqrt(5),0)
Step-by-step explanation:
3x^2 + 8y^2 = 24
Divide each side by 24
3x^2 /24 + 8y^2/24 = 24/24
x^2/8 + y^2 /3 = 1
The general equation of an ellipse is
(x-h)^2/ a^2 + (y-k)^2 / b^2 = 1
a>b (h,k) is the center
the coordinates of the vertices are (
±a,0)
the coordinates of the foci are (
±c,0), where ^c2=a^2−b^
2
The center is at (0,0)
a = sqrt(8) = 2sqrt(2)
The vertices are at ( (
±2 sqrt(2),0)
c = 8 - 3 =5
foci are (
±sqrt(5),0)
