The equation of the quadratic curve are:

Quadratic equation when the directrix is at y direction is of the form:

(x - h)² =  4P (y - k)

OR

standard vertex form, y = a(x - h)² + k     where a = 1/4p

The vertex for curve 1

v (h, k) = (-5, 4)

h = -5

k = 4

substitution of the values into the equation gives

y = a(x - h)² + k

y = a(x + 5)² + 4

Using (-3, 0) to solve for a

y = a(x + 5)² + 4

0 = a(-3 + 5)² + 4

-4 = a (2)²

a = -1

The equation is y = -(x + 5)² + 4

The vertex for curve 2

v (h, k) = (5, -4)

h = 5

k = -4

substitution of the values into the equation gives

y = a(x - h)² + k

y = a(x - 5)² - 4

Using (3, 0) to solve for a

y = a(x - 5)² - 4

0 = a(3 - 5)² - 4

4 = a (-2)²

a = 1

The hare can afford to nap for a maximum time of 3,690 seconds without losing the race if his speed is 15 m/s.

After running for 7 seconds, the hare has covered a distance of:

[tex]distance = speed \times time\\distance = 15 \times 7\\[/tex]

distance = 105m

The hare is now 895 m away from the starting line and 100 m away from the finish line.

The hare needs to cover a distance of 100 m to reach the finish line, while the tortoise needs to cover a distance of 895 m.

calculate the time it would take the tortoise to reach the finish line:

[tex]time = \frac{100}{0.27}[/tex] = 3704 seconds

The maximum speed of the hare is 15 m/s, which means the time it would take the hare to cover the distance is:

[tex]time = \frac{100}{15}[/tex] = 6.67 seconds

The function rule for the line that passes through the origin and (-6,-12) is y = 2x.

In mathematics, a function is a rule that assigns to each element in a set a unique output value.

To find a function rule for the line that passes through the origin (0,0) and the point (-6,-12), we first need to determine the slope of the line. The slope of a line represents the rate of change between the x and y coordinates. We can find the slope using the formula:

slope = (y₂ - y₁)/(x₂ - x₁)

where (x₁, y₁) represents the coordinates of the first point, and (x₂, y₂) represents the coordinates of the second point.

Using the given points, we can substitute in the values:

slope = (-12 - 0)/(-6 - 0)

slope = -12/-6

slope = 2

Now that we have the slope, we can use the point-slope form of a linear equation to find the function rule:

y - y₁ = m(x - x₁)

where m is the slope, and (x₁, y₁) represents the coordinates of a point on the line.

Substituting in the values we have so far, we get:

y - 0 = 2(x - 0)

y = 2x

Answer:

The sum of the digits in the mystery year is 9

Step-by-step explanation:

Let me try to help you

given the number of packages of hot dogs is d

given the number of packages of buns is b

so the total of hot dogs = total of buns

=> 8d = 6b or 4d = 3b

The number can be only integers like 1, 2, 3, 4, 5

So the smallest integer for d is 3 and b is 4

If you buy 3 packages of hot dogs, the number of hot dogs is 3 x 8 = 24

If you buy 4 packages of bun, the number of buns is 4 x 6 = 24

Divide #hot dogs by #packages of buns

So 24/4 = 6

Divide the result by 1/3

6 / (1/3) = 18

Sum of the digits

1 + 8 = 9

Answer: To solve the system of equations using substitution, we'll start by rearranging one of the equations so that one of the variables can be expressed in terms of the other. In this case, we'll rearrange the second equation to find y in terms of x.

y = 2x + 4

Next, we'll substitute this expression for y into the first equation:

+3x + 5(2x + 4) = 7

Expanding the right-hand side:

+3x + 10x + 20 = 7

Combining like terms:

13x + 20 = 7

Subtracting 20 from both sides:

13x = -13

Dividing both sides by 13:

x = -1

Finally, we'll use the expression we found for y in terms of x to find the corresponding value of y:

y = 2x + 4

y = 2(-1) + 4

y = -2 + 4

y = 2

So the solution to the system is (x, y) = (-1, 2).

For a certain species of virulent bacteria with the rate of growth of the bacterial population as proportional to the number the bacteria present after 3 hours is 256000.

A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decline or exponential growth, and so forth.

When there is exponential growth, the quantity grows initially extremely slowly and subsequently quickly. Over time, the rate of change quickens. As time goes on, the rate of increase accelerates. It is intended for the quick growth to be a "exponential increase".

The species of bacteria follow an exponential growth pattern.

The exponential growth is given as:

[tex]A(t) = A_0e^{kt}[/tex]

Where, A₀ is the initial population = 4000

k = constant

t = time = 30 minutes = 1/2 hour.

The bacteria doubles in 30 minutes, thus A(t) = 2(4000) = 8000.

Substituting the values in the equation:

[tex]8000 = 4000e^{k(\frac{1}{2} )}\\\\2 = e^{k(\frac{1}{2} )}[/tex]

Takin ln on both sides of the equation:

ln(2) = 1/2 k

2(ln(2)) = k

k = 1.38

The number of bacteria present after 3 hours:

[tex]A(t) = 4000e^{(1.38)(3)}\\\\[/tex]

A(t) = 256000

Hence, for a certain species of virulent bacteria with the rate of growth of the bacterial population as proportional to the number the bacteria present after 3 hours is 256000.

The required adult tickets and 104 child tickets, which gives a total revenue of $1820.

An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable, then, is a symbol denoting a number whose value is unknown. In this case, x + 5 = 10. "X" in this case is a variable.

Let x be the number of adult tickets sold and y be the number of child tickets sold.

We know that the total number of tickets sold is 220:

x + y = 220

We also know that the total revenue from ticket sales is $1820:

13x + 3y = 1820

We can use the first equation to solve for y in terms of x:

y = 220 - x

Substituting this into the second equation, we get:

13x + 3(220 - x) = 1820

Simplifying this equation:

10x + 660 = 1820

10x = 1160

x = 116

Therefore, the theater sold 116 adult tickets last night.

To check, we can substitute x = 116 into the equation for y:

y = 220 - x = 220 - 116 = 104

So, the theater sold 116 adult tickets and 104 child tickets, which gives a total revenue of $1820.

so,slope m between points P and Q is m=-2-4/-4-(-1)

m=-6/-3

m=2

Now,we know that equation of line

Based on the information in the graph, it can be inferred that Josephine must have painted 1/4 of the painting.

To find the amount (fraction) of the paint, Josephine should have painted the section marked on the image. To know how much that section is equivalent to, we must take as a reference that the entire painting would be 1.

So, if we divide the painting in half, it would be 1/2, that is, we paint 1 of 2 possible parts. However, in the case of Josephine there are 4 possible parts and she only painted one. From the above, what she should have painted was 1/4.

The p-value of the test statistic is 0.0401, which is less than the commonly used significance level of 0.05.

In statistical analysis, hypothesis testing is an essential method used to make inferences about population parameters using sample data. In this case, a hospital director wants to test a claim that the percentage of insured patients is less than the expected percentage.

The alternative hypothesis is that the percentage of insured patients is less than the expected percentage. To test this hypothesis, the director will use a one-tailed z-test for proportions. The test statistic is calculated as:

z = (p - P) / √(P(1-P) / n)

where p is the sample proportion, P is the expected proportion under the null hypothesis, and n is the sample size.

In this case, the sample proportion is 115/230 = 0.5, and the expected proportion is not specified. However, since the null hypothesis is that the percentage of insured patients is equal to the expected percentage, we can use the observed percentage of 55% as a reasonable estimate of the expected percentage. Thus, P = 0.55.

Plugging in these values, we get:

z = (0.5 - 0.55) / √(0.55 * 0.45 / 230) = -1.74

p-value = -1.74/0.069 = 0.0401

Trough this one we have identified that the test statistic's p-value is 0.0401, indicating that it is below the widely accepted significance level of 0.05.

The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed one, assuming the null hypothesis is true.

Option D (x, y)→ (-2x, 2y) is the transformation that maps triangle UVW to triangle EFG.

In mathematics, a transformation refers to a process of changing the position, size, or orientation of a geometric shape. It is a fundamental concept in geometry, algebra, and other branches of mathematics that studies the properties of objects and their relationship with space.

Transformations can be classified into two main types: rigid and non-rigid transformations. Rigid transformations preserve the size and shape of the object while changing its position and orientation. Common examples of rigid transformations are translations, rotations, and reflections. Non-rigid transformations, on the other hand, change the size and shape of the object as well as its position and orientation.

Transformations are used in various areas of mathematics and science, such as computer graphics, physics, and engineering. They are also important in real-world applications, such as in designing and modeling objects, analyzing data, and solving practical problems.

The transformation involves a reflection across the y-axis (multiplication by -1 on the x-coordinate) and a dilation by a factor of 2 in the y-direction (multiplication by 2 on the y-coordinate).

Applying this transformation to the coordinates of triangle UVW:

(0, -2) -> (0, -4)

(2, 0) -> (-4, 0)

(-2, 2) -> (4, 4)

These transformed coordinates match the coordinates of triangle EFG, so option D is the correct answer.
