Answer:  What an entrepreneur really is, though, is someone who runs their own business and takes a risk to do it.

Step-by-step explanation:

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

Answer: To find the perimeter of the door on a scale drawing, we need to first determine the dimensions of the door on the scale drawing.

If the actual height of the door is 7 centimeters, then the height on the scale drawing will be:

7 cm ÷ 3.5 = 2 cm

Similarly, if the actual width of the door is 3 centimeters, then the width on the scale drawing will be:

3 cm ÷ 3.5 = 0.857 cm

Now we can use these dimensions to find the perimeter on the scale drawing:

Perimeter = 2 × (height + width) = 2 × (2 cm + 0.857 cm) = 2 × 2.857 cm = 5.714 cm

Therefore, the perimeter of the door on the scale drawing is 5.714 centimeters.

Step-by-step explanation:

A trapezoid is a quadrilateral with one pair of parallel sides.

The median of a trapezoid connects the midpoint of the non-parallel sides.

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.

In the figure,

[tex]IJ=\dfrac{(HG+EF)}{2}[/tex]

Substituting the values we have, HG = 8, EF = 12 gives us:

[tex]IJ=\dfrac{(HG+EF)}{2}[/tex]

[tex]IJ=\dfrac{(8+12)}{2}[/tex]

[tex]IJ=\dfrac{20}{2}[/tex]

Answer:

The equilibrium price is $250.

The equilibrium quantity is 26 units.

Step-by-step explanation:

To find the equilibrium price, we need to find the price at which the quantity demanded equals the quantity supplied. This occurs when q (quantity demanded) equals q (quantity supplied).

So, we can set the two equations for q equal to each other:

(380-p)/5 = (p-172)/3

To solve for p, we can cross-multiply and simplify:

3(380-p) = 5(p-172)

1140 - 3p = 5p - 860

1140 + 860 = 8p

2000 = 8p

p = 250

Therefore, the equilibrium price is $250. We can plug this value back into either equation for q to find the equilibrium quantity.

Using q = (380-p)/5, we get:

q = (380-250)/5 = 26

So the equilibrium quantity is 26 units.

Answer:

Step-by-step explanation:

To write the equation of the line that passes through the points (3, -4) and (7, 6), we can follow these steps:

Step 1: Find the slope of the line

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Plugging in the given values, we get:

slope = (6 - (-4)) / (7 - 3)

slope = 10 / 4

slope = 5 / 2

Step 2: Use point-slope form to write the equation of the line

Point-slope form of a line with slope m passing through a point (x1, y1) is given by:

y - y1 = m(x - x1)

We can use either of the given points to write the equation. Let's use (3, -4):

y - (-4) = (5/2)(x - 3)

Simplifying this equation, we get:

y + 4 = (5/2)x - (15/2)

Subtracting 4 from both sides, we get:

y = (5/2)x - (23/2)

This is the equation of the line in point-slope form.

Step 3: Simplify the equation if it is not in point-slope form

The equation we obtained in step 2 is already in point-slope form, so we do not need to simplify it any further.

Note: If the line was horizontal (i.e., it had zero slope), then its equation would be y = constant, where the constant is the y-coordinate of any point on the line. If the line was vertical (i.e., its slope was undefined), then its equation would be x = constant, where the constant is the x-coordinate of any point on the line.

==================================================

Explanation:

A function curve is considered increasing when moving uphill as you move to the right.

We're going uphill on the interval [tex]-1.5 < \text{x} < 2[/tex] which translates to the interval notation [tex](-1.5, 2)[/tex]. Be sure not to confuse this with ordered pair notation which unfortunately looks identical. The curved parenthesis are used to exclude each endpoint.

When moving to the right, we go downhill on two separate regions:

The first portion translates to the interval notation [tex](-\infty,-1.5)[/tex]

The second portion translates to [tex](2,\infty)[/tex]

We glue those regions together with a union symbol to get [tex](-\infty,-1.5) \cup (2,\infty)[/tex]

The union symbol basically means "or" when it comes to interval notation. So we are decreasing on the interval [tex](-\infty,-1.5)[/tex] or decreasing on the interval [tex](2,\infty)[/tex]

Based on division operation, the number of boxes of papers that the back of Nico's truck can stack in is 224.

Division operation is one of the four basic mathematical operations, including addition, subtraction, and multiplication.

Division operation involves the dividend divided by the divisor to produce a result known as the quotient.

In this situation, the volume of Nico's truck is determined as the dividend. The volume of each box of paper is determined as the divisor.

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).

Answer: To find the points where the circle intersects the line x=1, we substitute x=1 in the equation of the circle:

2(1)² + 2y² - 5(1) + 7y - 36 = 0

Simplifying, we get:

2y² + 7y - 31 = 0

We can solve this quadratic equation by using the quadratic formula:

y = (-7 ± √(7² - 4(2)(-31))) / (2(2))

y = (-7 ± √225) / 4

y = (-7 ± 15) / 4

Therefore, the points where the circle intersects the line x=1 are (1, 2) and (1, -4).
