What is equation of an ellipse?
The standard equation of an ellipse centered at (h, k) with a major axis parallel to the x-axis is given by:
[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]
where the coordinates of the vertex are (h±a, 0), coordinates of co-vertex are (h, k ± b) and the coordinates of foci are (h±c, k), where a² = c² + b².
According to the given question:
Given foci of the ellipse :
(-6, -1) and (-6, -7)
Co-vertices of the ellipse :
(-2, -4) and (-10, -4)
From the given foci and vertices ,
c = -1 - (-7) /2 = 3
b = -2 - (-10) /2 = 4
c² = a² + b²
∴ a² = 3 x 3 + 4 x 4 = 25
( h, k) = (-6 - 6 /2 , -1 - 7 / 2) = (-6, -4)
Equation of the ellipse is given by:
(x - h)²/ a² + (y - k)²/b² =1
(x - (-6))²/ 25 + (y - (-4))²/16 = 1

5 4/8 + 1 3/8 =
1. 33/8
2. 55/8
3. 6 7/16
Answer: 2. 55/8
Step-by-step explanation: Add the whole numbers first (5+1 = 6), then add the fractions (4/8 + 3/8 = 7/8). Now we have 6 7/8 and since they want the answer in fraction form we will multiply the 6 and the 8 (6x8=48) and then add the 7 to the 48 (7+48 =55) and we leave our answer over the denominator which is 8. This leaves us with the final answer of 55/8
7. Population Growth The population of a southern city
follows the exponential law.
(a) If N is the population of the city and is the time in
years, express N as a function of t.
(b) If the population doubled in size over an 18-month
period and the current population is 10,000, what will
the population be 2 years from now?
15
a) If N is the population of the city and is the time in years, N expressed as a function of t is; N(t) = N₀*e^(kt)
b) The population 2 years from now will be; 25198 people
How to solve the exponential growth model?The general formula for exponential growth model is;
N(t) = N₀*e^(kt)
where;
f(x) is exponential growth function
N₀ is initial amount
t is time
k is constant
a) We are told that;
N is the population of the city.
t is the time in years
Thus, N expressed as a function of t is;
N(t) = N₀*e^(kt)
b) We are told that the population doubled in size over an 18-month
period . Thus, the equation would now be;
N(t) = N₀*2^(t/18)
Thus, if the current population is 10000, then it means that 2 years from now, we will have;
N(2) = 10000 * 2^(24/18)
I used 24 because 2 years is 24 months
Thus;
N(2) ≈ 25198 people

The sample size is necessary if the 95% ci for p is to have a width of at most 0.15 irrespective of p being 385 people.
In statistics, a confidence interval describes the likelihood that a population parameter will fall between a set of values for a given percentage of the time. Confidence intervals that include 95% or 99% of anticipated observations are frequently used by analysts.
The largest confidence interval occurs when p = .5
The standard error = [tex]\sqrt{\frac{(0.5)^{2} }{x} }[/tex]
The z* for a 95% confidence interval = 1.96

A square is inscribed in a circle. Write the area of the square as a function of the radius.
Area will be 2[tex]r^{2}[/tex]
What is area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's form.
Given radius of circle is r
Then area of circle=π[tex]r^{2}[/tex]
The diagonal of the square is comparable to the diameter (2r) of the circle since two opposing corners of the square contact it.
Now, we will set up Pythagoras' Theorem to determine one side of the square:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
Since it is a square a=b which means all the sides are same
∴2[tex]a^{2}[/tex] = [tex]c^{2}[/tex]
We know c, which is 2r, the diagonal.
∴2[tex]a^{2}[/tex] = [tex](2r)^{2}[/tex]
⇒[tex]a^{2}[/tex] = 2[tex]r^{2}[/tex]
We can leave it as [tex]a^{2}[/tex]

be after 3 years?
Answer:
The total value of the account after 3 years will be $5,503.52.
Step-by-step explanation:
A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Tyler's bank account pays a straightforward yearly financing cost of 3.25%. Assume he stores $5,000 in the record and sets aside no extra installments or withdrawals for a long time.
The total value of the account after 3 years will be calculated as,
A = $5,000(1 + 0.0325)³
A = $5,000 x (1.0325)³
A = $5,000 x 1.1007
A = $5,503.52
The total value of the account after 3 years will be $5,503.52.

how much is 1kg of corn plus 1 cup of precooked corn ??
Answer:
Step-by-step explanation:
It is not possible to accurately compare the weight of 1 kilogram of corn to 1 cup of precooked corn because the weight of the corn will change after it is cooked. Corn is composed of water, starch, and other nutrients, and the weight of the corn will change depending on how much water is retained in the kernels.
For example, 1 cup of uncooked corn kernels (about 168 grams) will yield about 1 1/4 cups of cooked corn (about 210 grams), while 1 cup of precooked corn (about 160 grams) will yield about 1 cup of cooked corn (about 160 grams).
Therefore, the weight of 1 kilogram of corn (about 1000 grams) is significantly greater than the weight of 1 cup of precooked corn (about 160 grams). It is not possible to accurately compare the weight of these two quantities because they are in different states (raw versus cooked) and have different densities.
1. Arc QR =
Arc RS =
2. Find x and y -- if your answer is not a whole number, round to the tenths!
Answer:
Arc QR = 48°; Arc RS = 96°x = 74/7; y = 15Step-by-step explanation:
Given two inscribed quadrilaterals with various arcs and angles marked, you want to solve for specific unknown values.
1.The measure of an inscribed angle is half the measure of the arc it intercepts. The sum of arcs of a circle is 360°.
Arc PSR = 2·∠PQR = 2·93° = 186°
Arc RS = Arc PSR -Arc PS = 186° -90° = 96°
Arc QR = 360° -126° -90° -96° = 48°
The unknown arcs are ...
Arc QR = 48°Arc RS = 96°2.Opposite angles in an inscribed quadrilateral are supplementary:
105° +(7x +1)° = 180°
7x = 74 . . . . . . . . . . . divide by °, subtract 106
x = 74/7 = 10 4/7 . . . . . divide by 7
(4y +14)° +(7y +1)° = 180°
11y = 165 . . . . . . . divide by °, subtract 15
y = 15 . . . . . . . . . divide by 11
The values of x and y are ...
x = 74/7 = 10 4/7y = 15Graph the line with y-intercept -7 and slope 3/2
We are given the slope and the y-intercept so using the slope-intercept form:
y = mx + b, where m- slope, b- y-intercept.Substitute values to get:
y = (3/2)x - 7To graph a line we need two points, one is given, (0, - 7) - the y-intercept.
Find one more point, take even value of x to cancel the fraction, let it be x = 4, find its y-coordinate:
y = (3/2)*4 - 7 = 6 - 7 = - 1So our points are:
A(0, - 7) and B(4, - 1)Plot the points and connect to graph the line.
See below.
The graph of the linear equation:y = (3/2)*x - 7 can be seen in the image at the end.
How to graph the linear equation?A general linear equation is written as:y = a*x + b
Where a is the slope and b is the y-intercept. Then our linear equation is:y = (3/2)*x - 7
To graph it, we need to know two points in our line, to do so, we evaluate it in two different values of x. if x = 0y = (3/2)*0 - 7y = -7So we have the point (0, -7)
And if x = 2 then:y = (3/2)*2 - 7y = 3 - 7y = -4So we have the point (2, -4)
Now we just need to graph these two points and connect them with a line. You can see the graph below.
