Answer:
a) The location of the center of the ellipse is [tex](4,-6)[/tex]. It is determine by knowing the location of foci and Midpoint formula.
b) The standard equation of the ellipse is [tex]\frac{(x-4)^{2}}{31}+\frac{(y+6)^{2}}{81} = 1[/tex].
c) Major semiaxis ([tex]a[/tex]): [tex]a = 9[/tex], Minor semiaxis ([tex]b[/tex]): [tex]b = \sqrt{31}[/tex]
Step-by-step explanation:
a) Foci are located in the major axis of the ellipse, given the locations of ends of the major axis and locations of the foci. We can determine the location of the center of the ellipse by Midpoint formula:
[tex](h,k) = \frac{1}{2}\cdot F_{1}(x,y) + \frac{1}{2}\cdot F_{2} (x,y)[/tex] (1)
Where [tex]F_{1} (x,y)[/tex] and [tex]F_{2} (x,y)[/tex] are the locations of the foci.
If we know that [tex]F_{1}(x,y) = (4, -6-5\sqrt{2})[/tex] and [tex]F_{2} (x,y) = (4,-6+5\sqrt{2})[/tex], then the location of the center of the ellipse is:
[tex](h,k) = (4, -6)[/tex]
The location of the center of the ellipse is [tex](4,-6)[/tex]. It is determine by knowing the location of foci and Midpoint formula.
b) Now we need to determine the length of each semiaxis:
Major semiaxis ([tex]a[/tex])
[tex]a = \sqrt{[V_{2}(x,y)-(h,k)]\,\bullet\,[V_{2}(x,y)-(h,k)]}[/tex] (2)
[tex]V_{2}(x,y)-(h,k) = (4,3)-(4,-6)[/tex]
[tex]V_{2}(x,y) - (h,k) = (0, 9)[/tex]
[tex]a = 9[/tex]
Please notice that [tex]V_{2}(x,y)[/tex] is one of the vertices of the ellipse in the major axis.
Distance between focus and center ([tex]c[/tex])
[tex]c = \sqrt{[F_{2}(x,y)-(h,k)]\,\bullet\,[F_{2}(x,y)-(h,k)]}[/tex]
[tex]F_{2}(x,y) -(h,k) = (4-4,-6+5\sqrt{2}+6)[/tex]
[tex]F_{2}(x,y) - (h,k) = (0, 5\sqrt{2})[/tex]
[tex]c = 5\sqrt{2}[/tex]
Minor semiaxis ([tex]b[/tex])
[tex]c^{2} = a^{2}-b^{2}[/tex] (3)
[tex]b = \sqrt{a^{2}-c^{2}}[/tex]
If we know that [tex]a = 9[/tex] and [tex]c = 5\sqrt{2}[/tex], then the length of the minor semiaxis is:
[tex]b = \sqrt{31}[/tex]
In this case, the standard equation of the ellipse is defined by this formula:
[tex]\frac{(x-h)^{2}}{b^{2}}+\frac{(y-k)^{2}}{a^{2}} = 1[/tex]
If we know that [tex]a = 9[/tex], [tex]b = \sqrt{31}[/tex] and [tex](h,k) = (4, -6)[/tex], then the standard equation of the ellipse is:
[tex]\frac{(x-4)^{2}}{31}+\frac{(y+6)^{2}}{81} = 1[/tex]
The standard equation of the ellipse is [tex]\frac{(x-4)^{2}}{31}+\frac{(y+6)^{2}}{81} = 1[/tex].
c) The lengths of the axes are, respectively:
Major semiaxis ([tex]a[/tex]): [tex]a = 9[/tex]
Minor semiaxis ([tex]b[/tex]): [tex]b = \sqrt{31}[/tex]
Answer:
a) The location of the center of the ellipse is . It is determine by knowing the location of foci and Midpoint formula.
b) The standard equation of the ellipse is .
c) Major semiaxis (): , Minor semiaxis ():

It angle relationship and show work??
Answer:
m<x=146
Step-by-step explanation:
its a supplementary angle, meaning both angles add up to 180.
So we subtract 34 from 180 which is 146.
180-34=146
A bag contains 42 red, 45 green, 20
yellow, and 32 purple candies. You
pick one candy at random. Find the
probability that it is green or yellow.
Answer:
65/139 fraction form
0.47 decimal form
Answer:
Step-by-step explanation:
Total sample space , n (s) = 139
no of green candies , n (g) = 45
no. of yellow candies , n (y) = 20
Probability that is green or yellow is
P( g or y) = P(g) + P(y)
= n(g) / n(s) + n (y) / n(s)
= 45 / 139 + 20 / 139
= 65 / 139

Identify whether the figure is a polygon. If it is a polygon, name it by the number of its sides.
Answer:
not a polygon
Step-by-step explanation:
The given figure is not a polygon.
What is a polygon?A polygon is a closed plane figure formed by three or more line segments that meet at points called vertices.
Given is figure,
We know that, a polygon is made up of straight lines connected with each other in a close circuit.
Here, in the figure, there is no polygon, but two polygons joined by a vertex.
Hence, we can say that the given figure is not a polygon.

Carla e Ana foram tomar sorvete e gastaram r$ 23,00 dividido a conta em partes iguais, quanto cada uma pagou ? Gente me explica como faz a conta não só resposta por favor
Answer:
each of them has to pay $11.5 individually
Step-by-step explanation:
The computation of the amount paid by each one is shown below:
As carla and Ana gone for an icecream and the bill is $23 that should be divided equally
So here the carla should pay
= $23 ÷ 2
= 11.5
And, Ana should pay
= $23 ÷ 2
= $11.5
Hence, each of them has to pay $11.5 individually

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.
Answer:
AD = 7
Step-by-step explanation:
Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.
We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD
We can solve the problem by solving for x:
[tex]\frac{x}{32} =\frac{21}{24}[/tex]
Cross multiply.
[tex]24x = 672[/tex]
Simplify.
[tex]x=28[/tex]
Subtract the value of DB to find AD.
[tex]28-21=7[/tex]
[tex]AD=7[/tex]

How far up the house would a ladder be resting if it is 25 ft long and 3 ft
away from the house? Round to the nearest tenth if necessary.
5.3 ft
21 ft
24.8 ft
25.2 ft
Answer:
C
Step-by-step explanation:
The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.
Givens
a = 3
b = ?
c = 25 feet
Formula
a^2 + b^2 = c^2
Solution
3^2 + b^2 = 25^2
9 + b^2 = 625 Subtract 9 from both sides.
b^2 = 625 - 9
b^2 = 616 Take the square root of both sides.
b = sqrt(616)
b = 24.8
