The equation of ellipse with foci (2, 4) and (2, -8) and co-vertices (10, -2) and (-6, -2) is ((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

To find the equation of the ellipse, we first need to determine the center of the ellipse. Since the foci are on the same vertical line, the center of the ellipse is at the midpoint of the segment connecting the foci.

The midpoint of the segment connecting the foci is:

((2+2)/2, (4-8)/2) = (2, -2)

So the center of the ellipse is (2, -2).

Next, we need to determine the lengths of the semi-major and semi-minor axes. The semi-major axis is half the distance between the co-vertices, which is:

a = (10 - (-6))/2 = 8

The semi-minor axis is half the distance between the foci, which is:

c = (4 - (-8))/2 = 6

Now we can use the standard form of the equation of an ellipse centered at (h,k):

((x - h)^2 / a^2) + ((y - k)^2 / b^2) = 1

where a is the length of the semi-major axis and b is the length of the semi-minor axis.

Plugging in the values we have:

((x - 2)^2 / 8^2) + ((y + 2)^2 / 6^2) = 1

Simplifying and rearranging:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

So the equation of the ellipse is:

((x - 2)^2 / 64) + ((y + 2)^2 / 36) = 1

Step-by-step explanation:

The graph shows a parabola that opens downwards.

The vertex of a parabola that opens downwards is its maximum point.

From inspection of the graph, the maximum point is (-4, 6).

Therefore, the coordinates of the vertex are (-4, 6).

An arithmetic series is a set οf integers that are οrdered and have a cοmmοn difference between each fοllοwing wοrd. The cοmmοn difference, fοr instance, between the mathematical series 3, 9, 15, 21, and 27 is 6. An alternative term fοr an arithmetic sequence is an arithmetic prοgressiοn.

The first term is 21 and the cοmmοn difference is -4 (the amοunt added οr subtracted tο get frοm οne term tο the next).

The explicit fοrmula fοr an arithmetic sequence is a n = a + (n - 1)d2, where a is the first term, d is the cοmmοn difference, and n is the term number.

Substituting 21 fοr a and -4 fοr d, we get:

a n = 21 + (n - 1)(-4)

Simplifying, we get:

a n = 21 - 4n + 4

It can be estimated that approximately 3,042 people in attendance would prefer ketchup on a hot dog.

Thus, the correct answer is 3,042.

To determine how many people in attendance would prefer ketchup on a hot dog based on the data from the sample, we need to calculate the proportion of people who prefer ketchup and apply it to the total attendance.

The sample indicates that out of 150 people surveyed:

54 people prefer ketchup

36 people prefer relish

60 people prefer chili

To find the proportion of people who prefer ketchup, we divide the number of people who prefer ketchup by the total number of people surveyed:

Proportion of people who prefer ketchup = 54 / 150 = 0.36

Now, to estimate the number of people in attendance who would prefer ketchup on a hot dog, we multiply the proportion calculated above by the total attendance:

The simplified cos(t)/sec(t) to the trig function 1 - sin²(t), which is equivalent to cos²(t).

Recall that the secant function is defined as the reciprocal of the cosine function. In other words, sec(t) = 1/cos(t). Therefore, we can rewrite cos(t)/sec(t) as cos(t)/(1/cos(t)).

To simplify this expression, we can multiply both the numerator and the denominator by cos(t), which gives:

cos(t)/(1/cos(t)) = cos(t) * (cos(t)/1) = cos²(t)

Now, we have simplified cos(t)/sec(t) to cos²(t). Alternatively, we could have used the identity cos²(t) = 1 - sin²(t) to simplify the expression. This identity follows directly from the Pythagorean identity cos²(t) + sin²(t) = 1.

Starting with cos(t)/sec(t), we can substitute sec(t) = 1/cos(t) to get:

cos(t)/sec(t) = cos(t)/(1/cos(t)) = cos²(t)/1

Then, we can use the identity cos²(t) = 1 - sin²(t) to substitute cos²(t) in terms of sin(t):

cos(t)/sec(t) = cos²(t)/1 = (1 - sin²(t))/1 = 1 - sin²(t)

So, we have simplified cos(t)/sec(t) to the trig function 1 - sin²(t), which is equivalent to cos²(t).

1. In the calculation, only one pound of fish food is shared equally among one aquarium.

2. Each of the aquarium gets one pound of fish food

To solve the first part of the problem, we need to find the value of P when 1/2 ÷ 8 = P. By doing the calculation by hand, we get:

1/2 ÷ 8 = 0.0625. So, the  P = 0.0625.

In the second part of the problem, we know that 1 pound of fish is shared equally among a certain number of aquariums, and we need to find that number.

Since each aquarium gets 1 pound of fish food, and the total amount of fish food is 1 pound, we can set up an equation to solve for the number of aquariums:

1 pound of fish food / X number of aquariums = 1 pound of fish food per aquarium

Simplifying the equation, we get:

X = 1 pound of fish food / 1 pound of fish food per aquarium

X = 1 aquarium

Therefore, the pound of fish food is shared equally among 1 aquarium, and each aquarium gets 1 pound of fish food.

IJ is the median of the trapezoid. I is the midpoint of EH, and J is the midpoint of GF.

Also, the median of a trapezoid is also parallel to the parallel sides. IJ║ HG║ EF.

(The proof of this is extensive and requires drawing additional lines such as HJ and extending EF further until HJ and EF intersect at another point, Y. It is given as the other diagram. You also need prior knowledge of the midsegment of a triangle.)

The measure of the midsegment of a trapezoid, by definition, is also equal to the average of the measure of the parallel segments.
