Halley’s comet has an elliptical orbit with the sun at one focus. The eccentricity of the orbit is approximately 0.97. The lengt

kherson [118]

so the sun is one of the foci, and we have an eccentricity of 0.97. So the ellipse will look more or less like the picture below.

$\bf \textit{ellipse, horizontal major axis}\\\\\cfrac{(x- h)^2}{ a^2}+\cfrac{(y- k)^2}{ b^2}=1\qquad \begin{cases}center\ ( h, k)\\vertices\ ( h\pm a, k)\\c=\textit{distance from}\\\qquad \textit{center to foci}\\\qquad \sqrt{ a ^2- b ^2}\\eccentricity\quad e=\cfrac{c}{a}\end{cases}\\\\-------------------------------\\\\\begin{cases}h=0\\k=0\\a=35.88\\e=0.97\end{cases}\implies \cfrac{(x-0)^2}{35.88^2}+\cfrac{(y-0)^2}{b^2}=1\\\\-------------------------------$

$\bf e=\cfrac{c}{a}\implies 0.97=\cfrac{c}{35.88}\implies \boxed{34.8036=c} \\\\\\ c=\sqrt{a^2-b^2}\implies b=\sqrt{a^2-c^2}\implies b=\sqrt{35.88^2-34.8036^2} \\\\\\ \boxed{b\approx 8.72}\\\\ -------------------------------\\\\ \cfrac{(x-0)^2}{35.88^2}+\cfrac{(y-0)^2}{8.72^2}=1\implies \cfrac{x^2}{1287.3744}+\cfrac{y^2}{76.0384}=1$

Beth plays a video game in which she starts with 0 points. In round 1, she losses 31/2 points in round 2, she wins 281/2 points

Thepotemich [5.8K]

Answer:

$21\frac{1}{2} \ or\ 21.5$

Step-by-step explanation:

Given that:

Initial score of Beth = 0

Round 1 scores:

Points lost = $3\frac{1}{2} = 3.5$

Round 2 scores:

Points won = $28\frac{1}{2}=28.5$

Round 3 scores:

Points lost = $3\frac{1}{2} = 3.5$

To find:

The final score of Beth in the video game = ?

Solution:

Let us calculate the total points lost and total points won by Beth in the video game.

Then we will subtract the total points lost from the total points won to find the final score in the video game.

Total points won = 28.5

Total points lost = 3.5 + 3.5 = 7

So, final score = Total points won - Total points lost

Final score = 28.5 - 7 = 21.5 or $\bold{21\frac{1}{2}}$

How to find the domain of a function

Nata [24]

Answer: For the numerator, we know we have to have a positive number in the expression for ln. Therefore, 0">x−2>0, which means 2">x>2. Combining these, we get the domain of the function is all positive values for x which are greater than 2. In interval notation, this is simply (2,∞).
