Answer:
The equation of the ellipse is [tex]\frac{(x-2)^{2}}{8^{2}}+\frac{(y-10)^{2}}{10^{2}} = 1[/tex].
Step-by-step explanation:
The statement is incomplete, the most probable outcome may be the equation of the ellipse based on information given.
The equation of an ellipse whose major axis is vertical and is centered at a point different from origin is defined by:
[tex]\frac{(x-h)^{2}}{b^{2}} + \frac{(y-h)^{2}}{a^{2}} = 1[/tex] (1)
Where:
[tex](h,k)[/tex] - Coordinates of the center of the ellipse.
[tex](x,y)[/tex] - Coordinates of a point in the line of the ellipse.
[tex]a[/tex] - Length of the major semiaxis.
[tex]b[/tex] - Length of the minor semiaxis.
The coordinates of the center of the ellipse is midpoint of the segment between vertices, which are collinear with foci:
[tex](h,k) = \frac{1}{2}\cdot V_{1} (x,y) + \frac{1}{2}\cdot V_{2}(x,y)[/tex] (1)
Where [tex]V_{1} (x,y)[/tex] and [tex]V_{2} (x,y)[/tex] are the coordinates of the vertices.
If we know that [tex]V_{1} (x,y) = (2,0)[/tex] and [tex]V_{2} (x,y) = (2, 20)[/tex], then the coordinates of the center ellipse are:
[tex](h,k) = (2, 10)[/tex]
The length of the semimajor axis can be determined by using the following vectorial expression, which is equivalent to the Pythagorean Theorem:
[tex]a = \sqrt{[(h,k)-V_{1}(x,y)]\,\bullet\,[(h,k)-V_{1}(x,y)]}[/tex] (2)
If we know that [tex](h,k) = (2, 10)[/tex] and [tex]V_{1} (x,y) = (2,0)[/tex], then the length of the semimajor axis is:
[tex]a = \sqrt{(2-2)^{2}+(10-0)^{2}}[/tex]
[tex]a = 10[/tex]
And the length of the minor semiaxis is found by means of this Pythagorean identity:
[tex]b = \sqrt{a^{2}-c^{2}}[/tex] (3)
Where [tex]c[/tex] is the length between the center and any of the foci. This distance can be found by using this vectorial formula:
[tex]c = \sqrt{[(h,k)-F_{1}(x,y)]\,\bullet\,[(h,k)-F_{1}(x,y)]}[/tex] (4)
If we know that [tex](h,k) = (2, 10)[/tex] and [tex]F_{1} (x,y) = (2,4)[/tex], then the length between the center and any of the foci is:
[tex]c = \sqrt{(2-2)^{2}+(10-4)^{2}}[/tex]
[tex]c = 6[/tex]
And the length of the minor semiaxis is:
[tex]b = \sqrt{10^{2}-6^{2}}[/tex]
[tex]b = 8[/tex]
FInally, the equation of the ellipse is [tex]\frac{(x-2)^{2}}{8^{2}}+\frac{(y-10)^{2}}{10^{2}} = 1[/tex].

PT=y,TR=x+3,QT=2y,TS=3x-1 I'm confused and u really need help. My teacher isn't the greatest and wasn't much help.
Answer:
y=10, x=7
Step-by-step explanation:
Since the diagonals of a parallelogram bisect each other, PT should be equal to TR and QT should be equal to TS. So, y=x+3 and 2y=3x-1. Multiplying the first equation by 3 gives you 3y=3x+9. Using elimination to subtract these two equations gives you y=10. And since y=x+3, substitute y=10 there. 10=x+3, x=7.

find the circumference of the given circle pls pls
Step-by-step explanation:
circumstance of circle = 2πr= 2 × 22/7 × 2 = 88/7 cm. circumstance = 12.57 cmThe measure of central angle LOP is °. The length of LP is units. The length of MP is units.
Answer:
2.87units
Step-by-step explanation:
Find the diagram attached
The length of MP can be gotten using the pythagoras theorem
LP² = LM² + MP²
8.5² = 8² + MP²
72.25 = 64 + MP²
MP² = 72.25 - 64
MP² = 8.25
MP = √8.25
MP = 2.87units
Hence the length of MP is 2.87units
The measure of central angle LOP is 180°. The length of LP = 17 units. The length of MP = 15 units.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
The given is given in the question, as shown.
As per the question, we can see that
The measure of central angle LOP is 180°.
LM = 8 units
LP = 2OP
LP = 2(8.5)
LP = 17 units
So the length of LP = 17 units.
As we know that the Pythagorean Theorem,
LP² = LM² + MP²
17² = 8² + MP²
289 = 64 + MP²
MP² = 289 - 64
MP² = 225
MP = 15 units
Thus, the length of MP = 15 units.

Roxanne set a goal o drinking 2.5 liters of water each day.By 10:00 a.M., she drank 3/4 liter, and at lunch she had another 600 ml. In the afternoon. She purchased a ottle of water of water that contained 1.1 liters
Answer:
She has to drink 0.05 liters more
Step-by-step explanation:
She has to drink 2.5 liters of water each day.
The total amount of water she drank is
3/4 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters
0.75 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters
2.45 liters + x liters = 2.5 liters
x liters = 2.5 liters - 2.45 liters
x liters = 0.05 liters
She has to drink 0.05 liters more or has not drunk 0.05 liters.
If she drinks 0.05 liters more she will reach her set goal.
3/4 liters
1 liter= 1000ml
3/4 liters= 3* 1000/4 ml
3/4 liters= 3000/4 ml
3/4 liters= 750 ml
750 ml/ 1000ml = 0.75 liters

Answer:
3.5 works because 18-1.666 (2/3) X 3.5 = 12.169 which is less than 15.
4.5 works because 18-1.666 (2/3) X 4.5 = 10.503 which is also less than 15.
8.0 works because 18- 1.666 (2/3) X 8.0 = 4.672 which is also less than 15.
By looking at the number line included 4.5 is the only choice that is included in the shaded line part. So I think that that is the correct answer here.

Molly's family traveled 5/8 of the distance to her uncle's house on Saturday. They traveled 1/3 of the remaining distance on Sunday. What fraction of the total distance to her uncle's house was traveled on Sunday?
Answer: [tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
Given
On Saturday, Molly's family traveled [tex]\frac{5}{8}[/tex] of the total distance
On Sunday, they traveled one-third of the remaining distance.
Suppose the total distance is x
Distance traveled on Saturday is [tex]\dfrac{5x}{8}[/tex]
Remaining distance is
[tex]x-\dfrac{5x}{8}=\dfrac{3x}{8}[/tex]
On Sunday, they travel
[tex]\dfrac{1}{3}\times \dfrac{3x}{8}=\dfrac{x}{8}[/tex]
fraction of total distance traveled on Sunday is [tex]\dfrac{1}{8}[/tex]

Your answer
Answer:
16°
Step-by-step explanation:
Reference angle = [tex] \theta [/tex]
Side Opposite to reference angle = 14
Adjacent side = 48
Hypotenuse = 50
Let's apply arcsin:
Thus:
[tex] \theta = sin^{-1}(\frac{Opp}{Hyp}) [/tex] (recall: SOHCAHTOA)
Plug in the values
[tex] \theta = sin^{-1}(\frac{14}{50}) [/tex]

What is X?
Thanks so much xx
Answer:
X= 7
Step-by-step explanation:
Well first combine like terms
27x-9=180
Isolate from the variable
27x=189
x=7
The final answer is 7
Answer:
x =7
Step-by-step explanation:
( 10x -1) +(17x -8 ) =180
step 1 : since you have a plus sign in between it make it easy
so take care of the parentheses first
10x -1 + 17x - 8 = 180
step 2 : put together thw variable x
10x + 17x -1 -8 = 180
27x -9 =180
step 3 : take out -9 to the right and the sign will change
27x = 180 +9
27x = 189
x = 189 ÷ 27
x = 7

Parker needs to buy bouquets for table centerpieces. Her client has a budget of $250. If the bouquets cost $14.95 each, which direct variation equation can you use to determine the number of flower bouquets Parker can purchase?
A. x=14.95y
B. y=250x
C.250=14.95x
D. y=250(14.95)
Answer:
C
Step-by-step explanation:
as stated by the questions, the client has a budget of $250, which means we can't exceed $250. This will be our y (dependent variable, as the cost for y depends on how many bouquets we will purchase).
the bouquets cost 14.95 each, so if we have x bouquets , that means that the cost will be 14.95x (independent variable, as this gives the value of y).
therefore, the equation is 250=14.95x, which is C
but let's do process of eliminiation to double check:
if we look at the options, B and D are out (the cost of the bouquets isn't $250 each and also we can't have 250 bouquets , that would be too expensive for the client).
that leaves A and C
A isn't the correct answer. At first glance, it looks like we just switched x and y around. However, it cannot work because x is always the independent variable while y is the dependent variable (the value of y depends on the value of x, while the value of x doesn't depend on y).
Also, there's no mention of the $250 budget in A
by process of elimination and by the explanation above C is the correct answer.
Hope this helps!

We had an exchange student who said all the cucumbers were raised on one collective the size of 10 sections. He didn't know how many people were on that farm but it employed many people. The farm was located near a very large city so transportation was not a problem. The state owned the farm.
