Which of the following statements about an ellipse is NOT true?

Mathematics
1 answer:
jeyben [28]3 years ago
7 0

Answer: (b) The focus of an ellipse is always located precisely at the center of the ellipse.

Step-by-step explanation:

An ellipse is defined as <em>"a closed curve with two axes of symmetry (major axis and minor axis) that results in cutting the surface of a cone by an oblique plane to the axis of symmetry with an angle greater than that of the generatrix with respect to the axis of revolution"</em>. That is why the ellipse is considered a conic figure.

To understand it better: an ellipse has two points on its major axis that are equidistant from the center , which are called foci,  being this distance constant. In addition, the eccentricity allows to know how far the foci are from the center of the ellipse.

Therefore, the statement that indicates an ellipse has only one focus located  precisely at the center is incorrect.

-2x+6= 28
you want to get (2x) by itself so you subtract 6 from 28 on both sides
-2x= 22
then you want to get x by itself so you divide 2 on both sides
X= -11
Hope this helps!!! You could also use photomath to see if your answer is correct

Will the graph of the line represented by the table intersect the graph of y = 5x + 4? Explain.A table showing data of x and y a
weqwewe [10]

Answer:

you'll need to identify the equation of the line represented in the table. By plugging in coordinates given in the table, it's possible to identify the slope and y-intercept of the line.

Which coordinates tell us the y-intercept of the line? Once the intercept value is identified, it's possible to determine the slope using y = mx + b and plugging in values for b, x, and y. The y-intercept is represented by b. The x and y can be replaced with any of the values in the table.

Alternatively, the slope formula (Δy / Δx) can be used to determine slope.

Once the equation is identified, it will be possible to tell if the lines intersect.

If they have the same slope and different y-intercepts, they will be parallel.

If they have the same slope and the same y-intercept, they will lie on top of each other.

If they have different slopes and different y-intercepts, they will meet at a point.

If they have different slopes and the same y-intercept, they will meet at a point.

eimsori [14]

Answer:

6.68 ounces

Step-by-step explanation:

Maggie combines 8.27 ounces of strawberries and 6.65 ounces of blueberries to make a fruit bowl

= 8.27 + 6.65

= 14.91 ounces

She will have 1.56 ounces left over

= 14.91-1.56

= 13.36 ounces

Therefore the number of ounces in each fruit bowl can be calculated as follows

= 13.36/2

= 6.68 ounces
