12x6.5x1.25=97.5 cubic centimeters answer B
The equation of an ellipse is:
(x-h)²/a² + (y-k)²/b², where h, k are the coordinates of the center, a & b represent half of the major & minor axis respectively.
The given equation is:
x²/100 + y²/36 = 1.( a =10 and b = 6)
CENTER: Since h and k = 0, then the center of this ellipse is the origin (0,0)
VERTICES: a² = 100, → a = +10 and a = -10, then the right vertex is (10,0) and the left vertex is (-10,0)
FOCI: The distance "c" from the center to the focus is given by the following:
c² = a² - b²
c² = 100 - 36 = 64 and c = +8 and - 8
The coordinate of the right focus F₁(8,0) and F₂(-8,0) for the left focus
Answer:
Geometrically, ca is an extension or contraction of a, and algebraically is a multiplication of c times every coordinate of a.
Step-by-step explanation:
<em>A vector is an element of a vectorial space which could have n-coordinates</em> (or dimensions). <em>A scalar is just a number</em> (they don't specify if it is real, complex, rational, etc.).
In order to find ca (or c*a), we have that, in general
is the vector a, and ca is c times the vector a
Geometrically, this <em>represents an extension or contraction of the vector a</em>.
H = d/3 +2
h - 2 = d/3
3(h -2 ) = d
Ans: d = 3(h-2)
d = 3h - 6 (after expanding)
Answer:
If I am correct the perimeter is 24
Step-by-step explanation:
Count how many are on the top which is 9. 2 sides are the same so 9+9=18. (OUR FIRST PART) Now the sides are 5 but WE ALREADY COUNTED 2 ON EACH SIDE SO THAT IS 3=3=6. Now add. 18+6= 24
