Dada la ecuacion 25x2 + 4y2 = 100, determina las coordenadas de los vertices, focos, las longitudes de los respectivos ejes mayo
Likurg_2 [28]

Answer:

The given equation is

25x^{2} +4y^{2}=100

Which represents an elipse.

To find its elements, we need to divide the equation by 100

\frac{25x^{2} +4y^{2} }{100} =\frac{100}{100} \\\frac{x^{2} }{4} +\frac{y^{2} }{25} =1

Where a^{2} =25 and b^{2}=4. Remember that the greatest denominator is a, and the least is b. So, we extract the square root on each equation.

a=5 and b=2.

In a elipse, we have a major axis and a minor axis. In this case, the major axis is vertical and the minor axis is horizontal, that means this is a vertical elipse.

The length of the major axis is 2a=2(5)=10.

The length of the minor axis is 2b=2(2)=4.

The vertices are (0,5);(0,-5) and (2,0);(-2,0).

Now, the main parameters of an elipse are related by

a^{2}=b^{2} +c^{2}, which we are gonna use to find c, the parameter of the focus.

c=\sqrt{a^{2}-b^{2} }=\sqrt{25-4}=\sqrt{21}

So, the coordinates of each focus are (0,\sqrt{21}) and (0,-\sqrt{21})

The eccentricity of a elipse is defined

e=\frac{c}{a}=\frac{\sqrt{21} }{5}  \approx 0.92

The latus rectum is defined

L=\frac{2b^{2} }{a}=\frac{2(4)}{5} =\frac{8}{5} \approx 1.6

Finally, the graph of the elipse is attached.

A salesperson is paid a weekly salary of $1000, plus a commission of 5% of all her sales for the week.
garri49 [273]

Answer:

A) Total weekly salary = $1000 + ( 0.05 × s )

B) Yes this is a function

C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.

D) Domain will be [ 0, ∞ ]

Step-by-step explanation:

Given :

Weekly salary = $1000

Commission = 5% of all her sales

Let the number of sales be 's'

thus,

A) Total weekly salary = $1000 + ( 0.05 × s )

B) Yes this is a function

C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.

D) The domain here will be all the possible values of sales i.e 's'

Hence,

sales will always be positive

thus,

domain will be [ 0, ∞ ]

Find the slope.....................
bekas [8.4K]
Answer: 2x is the slope
Y= 2x-2
When finding slope think “rise over run” implying that when writing it as a fraction the rise would go over the run, this answer for example would be 2/1x because the line rises 2 for every 1 unit it passes. I don’t think you need this large of a explanation but I thought it would help
