g A circle is a special case of an ellipse. Explain how a circle is different from other ellipses.
Answer:
Main difference between circle & ellipse
Step-by-step explanation:
Circle is a line forming a close loop, all points on the loop line are at equal distance from the centre, that distance is called Radius. Eg : Wheel
Ellipse is also a close loop line, such that distance of locus of all points on the plane to two fixed points (foci) always sum up to same constant. Eg : Orbits of planets
Cricle is the round shape entity in which it contains only radius and double of radius is diameter Thus below explanation is the answer to the Question
Explanation:
Cricle is the most rounded shape. Its different from ellipse because it has the radius, chord and diameter.cricle can be drawn easily with compass and ellipse is oval shape.cricle contains two types perimeter cricle and normal cricle. Ellipse has also two types partial ellipse and normal ellipse.Cricle does not have major and minor axis length both are different.Thus we conclude that cricle is totally different from ellipse

3. Is y proportional to x and y?
Select the correct choice from the drop down.
Explain why or why not.
Type your response in the space below.
Answer/Step-by-step explanation:
Plug in the value of x in each row into the equation, y = 3.2x + 5, to find their corresponding y values respectively.
When x = 1:
y = 3.2(1) + 5
y = 3.2 + 5
y = 8.2
When x = 2:
y = 3.2(2) + 5
y = 6.4 + 5
y = 11.4
When x = 4:
y = 3.2(4) + 5
y = 12.8 + 5
y = 17.5
You have the following table:
x | y
1 | 8.2
2 | 11.4
4 | 17.5
To find out if y is proportional to x, find the ratio of y to x of each pair in the table.
x | y | ratio of y to x (y/x)
1 | 8.2 | 8.2/1 = 8.2
2 | 11.4 | 11.4/2 = 5.7
4 | 17.5 | 17.5/4 = 4.375
As you can see, here is no equal ratio. Each pair has a different ratio. Therefore, the a proportional relationship does not exist between x and y.
The equation of a lone is 3/5x + 1/3y = 1/15
Answer:
Step-by-step explanation:
x intercept is where the line is crossing the x axis or where y=0
y intercept is where the line crosses the y axis or where x=0
to find them, set other ting to zero
3/5x+1/3y=1/15
xintercept, set y=0
3/5x+1/3(0)=1/15
3/5x+0=1/15
3/5x=1/15
times 5/3 both sides
x=1/9
xintercept is x=1/9
yintercet
set x=0
3/5(0)+1/3y=1/15
0+1/3y=1/15
1/3y=1/15
times 3/1 both sides
y=1/5
yintercept is y=1/5
xint is x=1/9
yint is y=1/5

Answer:
[tex]m\angle{QPR}}=40[/tex]
Step-by-step explanation:
We are given that lines [tex]PQ[/tex] and [tex]PS[/tex] are perpendicular lines, meaning they intersect and each other, and as a result, create a right angle ([tex]90[/tex]).
With that being said, let's add the expressions representative of the two angles and set them equal to [tex]90[/tex] degrees:
[tex]7x-9+4x+22=90[/tex]
Combine like terms:
[tex]11x+13=90[/tex]
Subtract 13 from both sides of the equation:
[tex]11x=77[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]11[/tex]:
[tex]x=7[/tex]
Now, let's substitute this into the expression of angle [tex]QPR[/tex]:
[tex]7(7)-9[/tex]
[tex]=40[/tex]
_
You can check your work by substituting the value of [tex]x[/tex] into the other expression, and then adding that answer with our initial answer to make sure it equals [tex]90[/tex] degrees:
[tex]4(7)+22[/tex]
[tex]28+22=50[/tex]
[tex]40+50=90[/tex]
Since the two angles add up to 90, our answer is correct!

Coweta Nutrition sells shakes for $3.39 each. They also sell tea for $2.50. If Mrs.
Morgan bought 1 tea and spent $19.45 this week, not including tax, how many
shakes did she buy?*
Answer:
she bought 5 shakes
Step-by-step explanation:
shakes: $3.39
tea: $2.50
2.50 + 3.39s = 19.45
3.39s = 16.95
s = 16.95 ÷ 3.39
s = 5
Check:
2.50 + 3.39(5) = 19.45
or
2.50 + 3.39 + 3.39 + 3.39 + 3.39 + 3.39 = 19.45

8 x 7 56
now

Since this cannot be simplified, this is my answer.
The amount of solution Janitor has is [tex]\frac{1}{2}[/tex].
It is given that Janitor had 4/7 of a spray bottle of a cleaning solution out of which he used 1/8 of the solution in a day.
We have to find out that how much spray bottle he still have.
What will be the value , 2 times of 1/2 subtracted from 3 ?
The value will be 2.
Janitor had [tex]\frac{4}{7}[/tex] of spray bottle of a cleaning solution.
Amount of solution used by him in a day = [tex]\frac{1}{8}[/tex] of [tex]\frac{4}{7}[/tex]
= [tex]\frac{4}{56}[/tex] = [tex]\frac{1}{14}[/tex]
The amount of spray bottle which he have now ;
= [tex]\frac{4}{7}[/tex] - [tex]\frac{1}{14}[/tex]
= [tex]\frac{8-1}{14}[/tex]
= [tex]\frac{7}{14}[/tex] = [tex]\frac{1}{2}[/tex].
Thus , the amount of solution he has is [tex]\frac{1}{2}[/tex].
