The answer is 1

Work
11/6=1.833
You can serve 1.833 people? No because unfortunately, you can't feed a fraction of a person. So, you can actually only feed 1 person.

An equation of an ellipse is given. y2 = 1 − 3x2 (a) Find the vertices, foci, and eccentricity of the ellipse. vertex (x, y) = (

oksian1 [2.3K]

Answer:

Step-by-step explanation:

Given

$y^2=1-3x^2$

$3x^2+y^2=1$

$\frac{x^2}{(\frac{1}{\sqrt{3}})^2}+\frac{y^2}{1}=1$

therefore it is a vertical ellipse

thus a=1

$b=\frac{1}{\sqrt{3}}$

eccentricity of Ellipse

$e^2=1-\frac{b^2}{a^2}$

$e^2=1-\frac{1}{(\sqrt{3})^2}$

$e^2=1-\frac{1}{3}$

$e^2=\frac{2}{3}$

$e=\sqrt{\frac{2}{3}}$

Focii are $(0,ae)$ and $(0,-ae)$

$ae=1\times \sqrt{\frac{2}{3}}$

thus focii are $(0,\sqrt{\frac{2}{3}})$ & $(0,-\sqrt{\frac{2}{3}})$

(b) Length of major axis $=2a=2\times 1$

length of minor axis $=2b=2\times \sqrt{\frac{2}{3}}=2\cdot \sqrt{\frac{2}{3}}$

Triangle m is similar to triangle n triangle m has two angles with measures of 32 and 93 which two angle measures could be inclu

Elena L [17]

Answer:

C . 93° and 55°

Step-by-step explanation:

<u><em>The options of the question are</em></u>

A. 32 and 58°

B . 32 and 74

C . 93 and 55

D . 93 and 87

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

step 1

Find the measure of the third angle triangle M

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

Let

x ---> the measure of the third angle Triangle M

$32^o+93^o+x=180^o\\x=180^o-125^o=55^o$

step 2

Find the measure of the interior angles triangle N

Remember that

Triangle M and Triangle N are similar

That means

corresponding angles are congruent

The measure of the interior angles triangle N are

$32^o,93^o,55^o$

therefore

The answer is

C . 93° and 55°
