The vertices of an ellipse are (0,-1) and (8,-1). The endpoints of the minor axis are (4,1) and (4,-3). Write the equation of the ellipse in general form
Answers
Answer:
x^2+4y^2-8x+8y+4=0
Step-by-step explanation:
The general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.
What is an ellipse?An ellipse can be defined as a shape that looks like an oval circle.
The equation of an ellipse is
[tex]\dfrac{\left(x - h\right)^{2}}{a^{2}} + \dfrac{\left(y - k\right)^{2}}{b^{2}} = 1[/tex]
Where (h, k) is the center a and b are the lengths of the semi-major and the semi-minor axes.
The vertices of an ellipse are (0,-1) and (8,-1).
The endpoints of the minor axis are (4,1) and (4,-3).
The following equations take into account the different properties of an ellipse:
[tex]k = -1k=−1, h^{2} = a^{2}h 2 =a 2 , \left(h - 8\right)^{2} = a^{2}[/tex]
[tex]\begin{cases} b = 2 \\ k = -1 \\ h^{2} = a^{2} \\ \left(h - 8\right)^{2} = a^{2} \end{cases}[/tex]
We get that h = 4 k = -1, a = 4, and b = 2
The standard form of the given ellipse is
[tex]\dfrac{\left(x - 4\right)^{2}}{4^{2}} + \dfrac{\left(y + 1\right)^{2}}{2^{2}} = 1[/tex]
So the general form will be as : x² +4y² - 8x + 8y + 4 = 0.
Thus, the general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.

Si en un grupo de 10 personas se va a repartir refrescos de 10 sabores diferentes, y se sabe que hay uno de fresa y uno de piña ¿cuál es la probabilidad que el primero en ser repartido sea de piña y el segundo de fresa?
Answers
Respuesta: 0.011
Explicación paso a paso:
Dado que:
Número de sabor a refresco = 10
Número de sabor a piña = 1
Número de sabor a fresa = 1
P (primero es fresa) = número de sabor a fresa / número total de sabor
P (primero es fresa) = 1/10
P (el segundo es sabor a piña) = número de sabor a piña / número total de sabor
P (segundo sabor a piña) = 1/9
Probabilidades independientes:
P (primero es fresa) * P (segundo sabor a piña)
= (1/10) * (1/9)
= 1/90
= 0.011

Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equation that would be used to determine her weekly wages where,
Answers

x = the number of overtime hours worked.
Answer:
y = 16.83x + 450
Step-by-step explanation:
y - the amount earned
x - the hours worked overtime
450 is a constant, it is a value that is always present, and doesn't change or depend on anything. 16.83 is a coefficient whose value needs to be multiplied by the x value to hold true in the equation.
Solve for x given BD = 2x + 3 and AE = 6x + 4 . Assume B is the midpoint of overline AC and D is the midpoint of overline CE.
Answers
Answer: 1
From the second sentence, we have AB = BC = CD = DE = y. So AE = 4y and BD = 2y (you can see by drawing a diagram), and AE = 2BD. Substituting 2x + 3 for BD and 6x + 4 for AE in AE = 2BD, we have 6x + 4 = 2(2x + 3), 6x + 4 = 4x + 6. Solving, we see x = 1.

The length of a rectangle is 6 cm more than twice its width. The sum of the length and width is 24 cm What are the dimensions of the rectangle?
Enter your answers in the box.
Answers
Answer:
width:6, length:18
Step-by-step explanation:
You can subsititue width with x.
The length would then be 2x+6.
The value of width and length combined is 24.
The equation would be (2x+6)+(x)=24
Simplify to 3x+6=24
Subtract 6 from both sides giving 3x=18
Simplify to x=6
There's the width. Now you can substitute to find the length.
(6x2)+6=18

A new pair of shoes cost $78. They are on sale for $60.06.
What is the percent of change?
Answers
Answer: 23%
Step-by-step explanation:
From the question, we are informed that a new pair of shoes cost $78 and that they are on sale for $60.06.
The percent of change will be calculated as:
Change/ Cost price × 100
= [(78 - 60.06) / 78] × 100
= (17.94 / 78) × 100
= 0.23 × 100
= 23%
