If the eccentricity of an ellipse is 0.43 and the length of its major axis is 11 units, how far from the center are the foci located?

Answers

Answer:

2.365 unit far away the center are the foci located.

Step-by-step explanation:

Given : If the eccentricity of an ellipse is 0.43 and the length of its major axis is 11 units.

To find : How far from the center are the foci located?

Solution :

The eccentricity of an ellipse is defined as

$e=(c)/(a)$

Where, e is the eccentricity

c is the distance from center to focus

a is the distance between focus to vertex.

We have given,

Eccentricity of an ellipse is 0.43 i.e. e=0.43

The distance between focus to vertex is the half of the length of its major axis.

i.e. $a=(11)/(2)$

Substitute in the formula,

$0.43=(c)/((11)/(2))$

$c=0.43* (11)/(2)$

$c=2.365$

Therefore, 2.365 unit far away the center are the foci located.

Abed says he has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is y = 3x – 1. Which could be the other equation?

Answers

y = 3x + 23x – y = 23x – y = 1 3x + y = 1

The correct answer is:

Any equation that is a multiple of y=3x-1.

Explanation:

In order to graph as the same line, the equations must be the same. This means that all pieces of the first equation must be multiplied by the same factor, or the equation must be rewritten.

Javia ran 8 laps around a track to run a total of 1mile. How many laps will she need to run on Tuesday to run 3/8 of a mile

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Javia ran 8 laps around a track to run a total of 1 mile.

Number of miles in 1 lap = 1/8

Tuesday Javia ran 3/8 of a mile

Now, number of laps = 3/8 × 1/8

= 3 laps

Therefore, the number of laps Javia run on Tuesday to run 3/8 of a mile is 3.
