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]

Angles: Arcs & Angles need help thank you!!
Answer:
See answers below
Step-by-step explanation:
1) The typr of triangle in a semicircle is a right angle. Hence the measure of m<ABC is 90degrees
2) m<DEF = 1/2(144)
m<DEF = 144/2
m<DEF = 72degrees
3) From the trinagle
4x+3 + x+7 +90 ==180
5x + 100 = 180
5x = 180-100
5x = 80
x = 80/5
x = 16
<QRD = x+7
m<QRD = 16 + 7
m<QRD = 23degrees
4) Angle in the same segment are equal
5x-37= 3x+1
5x - 3x = 1+37
2x = 38
x = 38/2
x =19
arc NM = 2m<P

need help. asap. also need an explanation for the problem. :)
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

The volume of two similar solids are 128 m3
and 250 m². The surface area of the larger
solid is 250 m². What is the surface are of the
smaller solid?
Answer:
Solution given:
The volume of two similar solids are 128 m³
and 250 m³.
surface area of larger solid is 250m²
let surface area of smaller solid be x.
Since they are similar
[tex] \frac{250}{128} = \frac{250}{x} [/tex]
x=128
the surface are of the
smaller solid is 128m²

I’m really confused on how to write the range of inequality because it’s been a while. Can someone please help??
Answer:
y ≤ 0
Step-by-step explanation:
The arrow says that the function keep going down
the biggest y is 0
so we can write
y ≤ 0
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.
I think of number, double it and add 11. I get 25 a) using the statement above, form an equation. Use the letter 'x' as a unknown number b) solve the equation
Answer:
x = 7
Step-by-step explanation:
Let
x = the unknown number
double it :
2x
add 11:
2x + 11
I get 25:
The equation is
2x + 11 = 25
2x = 25 - 12
2x = 14
Divide both sides by 2
x = 14/2
x = 7

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
Hope this helps!

Find the value of x.
a) 80
b) 90
c) 45
d) 60
Answer:
b
Step-by-step explanation:
The tangent- tangent angle x is half the difference of its intercepted arcs.
Th sum of the arcs in a circle = 360°
major arc = 360° - 90° = 270° , then
x = [tex]\frac{1}{2}[/tex] (270 - 90)° = [tex]\frac{1}{2}[/tex] × 180° = 90° → b
