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)
A. The definition of a ray states that it extends infinitely in one direction. (A line extends infinitely in both directions, and a line segment has two finite end points.) Anything that extends infinitely has an infinite number of points.
Answer:
Step-by-step explanation:
- Turn 6.93 into a fraction:
- To turn into a mixed number, first multiply 6 and 100, then add 93. Put 693 over 100:

22 Odd Integers: 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59
Answer:
Option B.
2 × 3 interactions are possible.
Step-by-step explanation:
Since the experiment is manipulating room temperature, noise level, and room colour, this means that the experiment has 3 main effects, and for that reason has 3 independent variables.
Since there are 3 independent variables, there are 3! interactions.
And 3! = 3 × 2 × 1 = 2 × 3
