Write the equation of the ellipse with the endpoints of the major axis (-11, 0) and (11, 0) and minor axis (0, -3) and (0, 3)
I don't particularly care about the answer, more judt the explanation of how I'm supposed to find it. thank you!!
Answer:
x/121 + y/9 = 1
Step-by-step explanation:
The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.
Becasue the major axis is horizontal, this ellipse is wider than it is tall.
The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.
The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.
The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b
(x-0)²/11² + (y-0)²/3² = 1
*** x/121 + y/9 = 1
The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b
If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.
If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.

The 'brainly ellipse' is form this particular problem.

10 marbles what is the probability of drawing 2 blue marbles if the first marble is placed back in the bag before the second draw
Complete Question:
There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.
2 yellow, 3 pink, 5 blue
Answer:
[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]
Step-by-step explanation:
Given
[tex]Blue = 5[/tex]
[tex]Pink = 3[/tex]
[tex]Yellow = 2[/tex]
[tex]Total = 10[/tex]
When the first blue marble is selected, the probability is:
[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]
[tex]P(B_1) = \frac{5}{10}[/tex]
Since the first marble is not returned, we have the following marbles left
[tex]Blue = 4[/tex]
[tex]Pink = 3[/tex]
[tex]Yellow = 2[/tex]
[tex]Total = 9[/tex]
The probability of picking a second blue marble is:
[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]
[tex]P(B_1) = \frac{4}{9}[/tex]
So, the required probability is:
[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]
[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]
[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]
[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]
[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]
A circle has a circumference of 153.86153 units. What is the radius of the circle? This is on Khan accadamy so when I am done waiting i will give the answer.
Answer:
radius = 24.5 units
Step-by-step explanation:
153.86153 / 3.14 = diameter
diameter = 49 units
diameter / 2 = radius
49 / 2 = 24.5 units
A sphere has a diameter of 12 ft. What is the volume of the sphere? Give the exact value in terms of Pi.
Formula of volume of a Sphere is : V = 4/3 πr³
Here, Diameter (2r) = 12, so radius (r) = 12/2 = 6 feet
Substitute it into the formula,
V = 4/3 π(6)³
V = 4/3 *216π
V = 288π Ft² [ Answer in the term of π ]
You can also solve it for numeral value by substituting the value of π = 22/7
V = 288 * 22/7 = 905.15 Ft² [ Answer in numbers ]
Answer:
288 pi ft squared

Step-by-step explanation:
This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.

Answer: Slope of line = [tex]\frac{1.2}{2}[/tex]
Graph- see picture.
Step-by-step explanation:
Graphs are graphed using y=mx+b
Slope (m) is written as [tex]\frac{rise}{run}[/tex], and y coordinate is up and down, x is left & right.
The y coordinate adds 1.2 every time, so the rise is 1.2.
The x coordinate adds 2 every time, so the run is 2.
The y intercept (b) simply means where the line intercepts the y axis.
It is given that the y intercept is 0.
So, the graphing equation: y= [tex]\frac{1.2}{2}[/tex]x
We don't need to put the y intercept because it is 0!
The graph is attached!

The difference of two positive numbers is 51. The quotient when one integer is divided by the other is 4. Find the two integers.
Answer:
x = -17
y = -68
Step-by-step explanation:
x - y = 51
y/x = 4 so we can say that y = 4x
using substitution:
x - 4x = 51
-3x = 51
x = -17
find 'y':
-17 - y = 51
-y = 68
y = -68
check:
-17 - (-68) = 51
51 = 51
-68/-17 = 4
4 = 4
