Answer:
(x-1)²/49 + (y+3)²/16.51 = 1
Step-by-step explanation:
vertex (8,-3) Foci (6.7,-3) center (h,k) = (1,-3) , major axis parallel to x axis
a is the distance of the vertex from the center, and c is the distance of the foci from the center. b is semi-minor axis
b² = a² - c² Ellipse equation: (x-h)²/a² + (y-k)²/b² = 1
a = 8-1 = 7 c = 6.7 - 1 = 5.7
b² = 7² - 5.7² = 16.51
Ellipse equation: (x-1)²/49 + (y- -3)²/16.51 = 1 i.e. (x-1)²/49 + (y+3)²/16.51 = 1
Rearrange this equation <span>5x+3y=8x-7y so that all x terms are on one side and all y terms are on the other:
10y
</span><span>5x+3y=8x-7y => 10y = 3x, and x = ----------
3</span>
The formula to find the volume multiplies the length by the width by the height, so length is 7, the width is 2 and the height is 3.
7×2×3= 42
42 cubic units.
Answer:
36cm
Step-by-step explanation:
38 × 2 = 76
148 - 86 = 72
72/2 = 36
