HELPPP PLEASE!! Which two fixed points define the shape ellipse

Answers

The shape of an ellipse is defined by its two focii.

What is Ellipse?

A type of geometric shape that is symmetric and resembles a flattened circle is called Ellipse.

Two fixed points of a shape define focii  which are located on the major axis of the ellipse.

The longest diameter of the ellipse is called Major Axis, and  length of the major axis is equal to distance between the two focii.

The  curvature of the ellipse is determined by the focii of an ellipse.

if focii are further apart, the ellipse will be more circular and  focii are close together, the ellipse will be more elongated.

In addition to the focii, the shape of an ellipse is also determined by a second set of fixed points called vertices, which are located on the minor axis of the ellipse.

Hence,  the shape of an ellipse is defined by its two focii.

1) •There were 3,905 more hits on the schools website in January than February. •Feb. = 9854 hits.
•How many hits to the schools website have during both months?

A) About how many hits did the website have during Jan and Feb?

B) exactly how many hits did the website have during Jan and Feb?

Answers

Let

x---------> the number of hits in January

y---------> the number of hits in February

we know that

x=3,905+y --------> equation 1

y=9,854 --------> equation 2

Substitute equation 2 in equation 1

x=3,905+9,854

x=13,759

Part a) About how many hits did the website have during Jan and Feb?

x=13,759 ----> Round to nearest ten thousand-----> x=14,000

y=9,854----> Round to nearest ten thousand-----> x=10,000

x+y=14,000+10,000=24,000

the answer part a) is 24,000

Part b) Exactly how many hits did the website have during Jan and Feb?

x+y=13,759+9,854=23,613

the answer part b) is 23,613
In January, there were 13,759 hits and in February there were 9,854 hits.
During both the months, there were 23,613 hits to the school's website.
