The answer to your question is A. 1251cm
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)
Answer:
a) 13 cups
b) 1 .6kg
Step-by-step explanation:
a) 25 / 1.8 = 13.89
13 cups
to check the answer:
13 cups x 1.8kg per cup = 23.4kg in total
we can use 23.4 to figure out b
b) 25 kg - 23.4kg = 1.6kg
1.6kg
