Find the center, vertices, and foci of the ellipse with equation x squared divided by 9 plus y squared divided by 25
Answer:
[tex]C=(0,0)[/tex]
[tex]F=(\pm 4,0)[/tex]
[tex]V=(\pm 5,0)[/tex]
Step-by-step explanation:
From the question we are told that:
The Equation
[tex]\frac{x^2}{9}*\frac{y^2}{25}[/tex]
Generally
From the Equation
[tex]a^2=25[/tex]
[tex]a=5\\b^2=9\\b=3[/tex]
Therefore
[tex]c=\sqrt{a^2-b^2}[/tex]
[tex]c=\sqrt{25-9}[/tex]
[tex]c=\sqrt{16}[/tex]
[tex]c=4[/tex]
Generally the equation for center is mathematically given by
[tex]C=(h,k)[/tex]
[tex]C=(0,0)[/tex]
Generally the equation for foci is mathematically given by
[tex]F=(h,k \pm c,0)[/tex]
[tex]F=(\pm 4,0)[/tex]
Generally the equation for vertice is mathematically given by
[tex]V=(h,k \pm a,0)[/tex]
[tex]V=(\pm 5,0)[/tex]

Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents
Given:
In a circle, two chords AK and LJ intersect each other inside the circle at M.
Measure of arc AJ = 65 degrees.
Measure of arc KL = 85 degrees.
To find:
The measure of angle KML.
Solution:
Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.
Using Intersecting chords theorem, we get
[tex]m\angle KML =\dfrac{1}{2}(arcKL+arcAJ)[/tex]
[tex]m\angle KML =\dfrac{1}{2}(85^\circ +65^\circ )[/tex]
[tex]m\angle KML =\dfrac{1}{2}(150^\circ )[/tex]
[tex]m\angle KML =75^\circ[/tex]
Therefore, the measure of angle KML is 75 degrees.

The cost c per person to participate in a guided camping tour depends on the number of n participating in the tour. This relationship can be described by the function c = – 4n + 60, where 0 < n < 12. What is the rate of change described by this function?
Answer:
-4
Step-by-step explanation:
Given the function :
c = – 4n + 60
Where, c = cost of participation ;
n = number of persons
The cost equation can be related to the slope intercept, equation ;
y = mx + b
Where, m = Slope or rate of change
b = intercept
Comparing the slope intercept equation to the cost equation ;
m = - 4 ; Hence, the rate of change of cost is - 4

Answer:
124858
Step-by-step explanation:
The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.
6 + 2 + 8
6 * 2 = 12
6 * 8 = 48
Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2
12 + 48 = 60
60 - 2 = 58
Put them together

Which of the following correctly gives the center and radius of the circle defined by (2 -
- 7) + (y - 2)2 = 10?
O Center: (7, 2); Radius = 100
O Center: (7, 2); Radius - V10
O Center:(-7, - 2); Radius = 100
O Center:(-7, -2); Radius = 10
Answer:
Center = (7, 2); Radius = [tex]\sqrt{10}[/tex]
Step-by-step explanation:
(x - 7)^2 + (y - 2)^2 = 10
center = (7, 2)
Radius = [tex]\sqrt{10}[/tex]
Answer:
(x - 7)^2 + (y - 2)^2 = 10
center = (7, 2)
Radius = √10
Quadrilateral LMNO is a parallelogram, and LM=24-9 and NO=y-2, find the value of "y" and the length of NO.
Answer:
y = 7
NO = 5
Step-by-step explanation:
Let the side of the parallelogram LM and NO given be 2y - 9 and y - 2
Since LMNO is a parallelogram, hence;
LM = NO
2y - 9 = y - 2
2y - y = -2 + 9
y = 7
Since NO = y - 2
NO = 7 - 2
NO = 5
Mark said, “in the data set,4 5, 5, 8, the mean and mode the same.” Is he correct? Explain why or why not
Answer:
Mark is wrong.
Step-by-step explanation:
The mean of the data set is 5.5 because 4 + 5 + 5 + 8= 22. 22 divided by 4= 5.5. The mode is the number which shows up the most. 5 shows up the most in the data set, however 5 is not equal to 5.5. Therefore, Mark is incorrect.

Answer:
X = 44
Step-by-step explanation:
That square means that the angle is 90°, therefore you can subtract 46 from 90 to find x
90 - 46 = 44
Answer:
44
Step-by-step explanation:
That is a right angle so we just need to subtract 46 from 90, and 90-46 is 44. So 44 is the missing angle

Answer:
37 degrees
Step-by-step explanation:
The angles within a triangle always add up to 180 degrees. Right angles are always 90 degrees. 53 + 90 = 143 degrees. 180 - 143 = 37 degrees

Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
Answer:
18.) x = 6
20.) x = 11
Step-by-step explanation:
18.)
We know that line segments FC and ED are parallel to each other so they are congruent to each other:
-1 + 2x = 5 + x
-1 + x = 5
x = 6
20.)
We know that line segments DE and CF are parallel to each other so they are congruent to each other:
18 = -4 + 2x
22 = 2x
22/2 = x
11 = x

Mark filled 36 glasses with orange juice for a camp breakfast. If each glass holds 1 cup of juice, how many pints of orange juice did Mark use?
Answer:
18 pints of juice
Step-by-step explanation:
1 pint is equal to 2 cups, so knowing this we just divide 36 by 2
36/2 = 18
What is the equation of the line that passes through the points (15, 9) and (-2, 9)?
y=9
y=- 11/6x + 9
y= -17
y= 6x + 11
Answer:
y=-17x-25
Step-by-step explanation:
9-9=0
-2-15=-17
(y-9)÷(x+2)= -17
y-9=-17x-34
y= -17x-25

Question mark 1: Match the triangle to correct function and answer
Answer:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]x \approx 15.900[/tex]
Step-by-step explanation:
Each triangle is solved by means of trigonometric relations:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]\cos 58^{\circ} = \frac{x}{16}[/tex]
[tex]x = 16\cdot \cos 58^{\circ}[/tex]
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]\tan 44^{\circ} = \frac{x}{18}[/tex]
[tex]x = 18\cdot \tan 44^{\circ}[/tex]
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]\sin 49^{\circ} = \frac{12}{x}[/tex]
[tex]x = \frac{12}{\sin 49^{\circ}}[/tex]
[tex]x \approx 15.900[/tex]
