Write an equation in standard form of an ellipse that has a vertex at (0, 6), a co-vertex at (1, 0), and a center at the origin.
Answer:
The standard form of the equation of the ellipse is x² + y²/36 = 1
Step-by-step explanation:
* Lets revise the standard equation of the ellipse
- The standard form of the equation of an ellipse with
center (0 , 0) is x²/b² + y²/a² = 1
where,
* the length of the major axis is 2a
* the coordinates of the vertices are (0 , ±a)
* the length of the minor axis is 2b
* the coordinates of the co-vertices are (±b , 0)
* the coordinates of the foci are (0 , ± c), where c² = a² - b²
* Now lets solve the problem
∵ The vertex of the ellipse is (0 , 6)
∴ a = 6
∵ The co-vertex is (1 , 0)
∴ b = 1
∵ the center is the origin (0 , 0)
∵ The standard form equation is x²/b² + y²/a² = 1
∴ x²/(1)² + y²/(6)² = 1 ⇒ simplify
∴ x² + y²/36 = 1
* The standard form of the equation of the ellipse is x² + y²/36 = 1
What is the value of y in the equation 4x +3 y= 23 when x=2 , x=6
Answer:
5, -⅓
Step-by-step explanation:
x = 2:
4x + 3y = 23
3y = 23 - 4(2)
3y = 15
y = 5
x = 6:
4x + 3y = 23
3y = 23 - 4(6)
3y = -1
y = -⅓

Angles P and Q are supplementary. m∠P=43∘. Which statement is true?
m∠Q=147∘
m∠Q=47∘
m∠Q=137∘
m∠Q=43∘
P + Q = 180
43 + Q = 180

find C.P if S.P = Rs 208, profit percent = 4%
Answer:
Rs 200
Step-by-step explanation:
100/104×Rs 208
Rs 200
S.P = 208
4%×208=8.32
208-8.38=199.68
Therefore, C.P = ₹199.68

In 8- 11 find the area of each parrelogram or rhombus
The areas of the two parallelograms are 105 square inches and 20.997 square yards, respectively.
How to determine the area of a parallelogram
A parallelogram is a quadrilateral with two pairs of parallel sides with equal length and two pairs of angles of equal measure. The area of the parallelogram (A), in square yards or square inches, equals the product of its base length (b), in yards, and its height (h), in yards.
The area of each parallelogram is determined afterwards:
Exercise 10A = (10.5 in) · (10 in)
A = 105 in²
Exercise 11A = (9 yd) · (2.333 yd)
A = 20.997 yd²
The areas of the two parallelograms are 105 square inches and 20.997 square yards, respectively. [tex]\blacksquare[/tex]

Answer:
7. B 2·2·3·a
9. B 41°
Step-by-step explanation:
You want the greatest common factor of 24a² and 36ab, and you want the smallest integer-valued angle in an acute triangle with one angle 50 degrees.
7. GCFThe factors of 24a² are 2·2·2·3·a·a.
The factors of 36ab are 2·2·3·3·a·b.
The factors these lists have in common are 2·2·3·a, matching choice B.
9. AnglesIf one angle of a triangle is 50°, the sum of the other two angles must be ...
180° -50° = 130° . . . . . . sum of angles B and C
One of these angles will be the smallest it can be only if the other is the largest it can be. The largest integer acute angle is 89°, so the smaller angle will be ...
130° -89° = 41°
The smallest possible angle in the acute triangle is 41°.

I need help with this question and a step by step explanation for future references, Thanks!
Answer:
x = 7
y = -2
Step-by-step explanation:
Equation 1: 2x + y = 12
Equation 2: x - y = 9
Rewrite Equation 2 to make x the subject:
⇒ x = 9 + y
Substitute this into Equation 1 and solve for y:
⇒ 2(9 + y) + y = 12
⇒ 18 + 2y + y = 12
⇒ 18 + 3y = 12
⇒ 3y = -6
⇒ y = -2
Substitute found value of y into the rewritten Equation 2 and solve for x:
⇒ x = 9 + (-2)
⇒ x = 7
Step-by-step explanation:
2x + y = 12 equ 1
x - y = 9 equ 2
from equ 2 make x the subject
x - y = 9
x = 9 + y equ 3
substitute equ 3 to equ 1
2x + y = 12
2(9 + y ) + y = 12
18 + 2y + y = 12
3y = - 6
y = -2
substitute y = -2 into equ 3
x = 9 + (-2)
x = 9 - 2 = 7
(x, y) = (7, -2)
let's prove and see if we are correct
2x + y = 12
input the values of (x, y) = ( 7, -2) into the question
2(7) + (-2) = 12
14 - 2 = 12
12 = 12
for the second equation
x - y = 9
Input the values of (x, y) = ( 7, -2) into the question
7 - (-2) = 9
7 + 2 = 9
9 = 9

=========================================================
Explanation:
Count the number of leaves for each stem.
The first row has 5 leaves, the next has 8, and so on.
This is the list of leaf counts for each row when reading from top to bottom.
58873Add those leaf counts to get 5+8+8+7+3 = 31
There are 31 leaves total to represent the n = 31 values in this data set.
The median is in slot n/2 = 31/2 = 15.5 = 16 which is at the exact center.
Notice how 5+8 = 13 is too small compared to slot 16
But 5+8+8 = 21 is too big. Therefore, the median in slot 16 is somewhere in the third row.
Specifically, it's the third item in that row because 13+3 = 16
The third item in the the third row is the leaf 4. It pairs with the stem 3
stem = 3 and leaf = 4 combine to the value 34. The median is 34.
---------------------------------------
Another way to find the median:
Start with the first leaf in the first row (that value being 6). It pairs up with the last leaf in the last row (that value is 5). Cross those outer-most values from the list.
Repeat that step with the next outer-most values (7 in row one and 2 in row five). This process of crossing out the outer-most values will gradually narrow the list down until we approach the very middle item. You should arrive at the "4" in the third row.
This process is longer than the first method in the previous section, but it might be handy to see it being visual like this.
Answer: 26.533
Step-by-step explanation: add the leaf numbers and multiply them with the respective stem number and all those add together. the result divided by the sum of stem numbers.

Answer:
[tex]y = 5[/tex]
Step-by-step explanation:
Given function:
[tex]y=\dfrac{5x}{x+6}[/tex]
[tex]\implies y=5 \left( \dfrac{x}{x+6}\right)[/tex]
[tex]\textsf{As }x \rightarrow +\infty, \ \dfrac{x}{x+6} \rightarrow1[/tex]
[tex]\implies y\rightarrow5[/tex]
[tex]\textsf{As }x \rightarrow -\infty, \ \dfrac{x}{x+6} \rightarrow1[/tex]
[tex]\implies y\rightarrow5[/tex]
As [tex]x[/tex] approaches infinity and negative infinity, [tex]y[/tex] approaches 5 (but never gets there). Therefore, the horizontal asymptote is [tex]y=5[/tex]

Which of the following points is a solution to the system of equations x - y = 1 and -x + 3y = - 7?
(-2,2) is a solution.
0 (-2, - 3) is a solution.
(1. - 2) is a solution.
(4.3) is a solution
Answer:
(-2,-3)
Step-by-step explanation:
Put the equations over each other.
[tex] \binom{x - y = 1}{ - x + 3y = - 7 } [/tex]
Subtract the x values.
[tex] \binom{ - y = 1}{3y = - 7} [/tex]
Subtract on both sides.
[tex]2y = - 6[/tex]
Divide on both sides.
[tex]y = - 3[/tex]
Insert the y value into one of the equations.
[tex]x - ( - 3) = 1[/tex]
Get rid of the parenthesis.
[tex]x + 3 = 1[/tex]
Subtract on both sides.
[tex]x = - 2[/tex]
You could also individually plug in each solution into both equations to see if they are true.
