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)
You have to plug in 7 for f and 8 for k making it look like -5(7)-2+8-3(8), now multiply to get the further more, -35-2+8-24, now add or subtract to get -53
Hope this helps
Answer: 8 inches
Step-by-step explanation:
1x4=4 4+4=8
Since 45 = 45
then the two other sides are equal
(15)^2 = (side)^2 + (side)^2
225 = 2 (side)^2 divide 2 to both sides
112.5 = (side)^2 square root
side = 10.6
this is my answer
Answer:
Tyler ran <em>0.06 miles farther </em>than Elena
Step-by-step explanation:
From the graph we can find the distance ran by Tyler in 10 minutes is approximately 1.24 miles
Given the equation for Elena's distances and times is
y=8.5x, where x is the distance in miles and y is the time in minutes, we can know the value of x when y = 10 minutes
miles
With this numbers at hand, we can infer Tyler ran 1.24 - 1.18 = 0.06 miles farther than Elena
