The polynomial function with the given zeros x = 3 + i and x = -1 - √5 is:

f(x) = x⁴ - 4x³ - 6x² - 8x + 40

Here, we have,

To write a polynomial function with the given complex zeros, we need to consider their conjugate pairs.

The given zeros are x = 3 + i and x = -1 - √5.

Since complex zeros occur in conjugate pairs, the conjugates of the given zeros are x = 3 - i and x = -1 + √5, respectively.

To find the polynomial function, we can multiply the factors corresponding to each zero:

(x - (3 + i))(x - (3 - i))(x - (-1 - √5))(x - (-1 + √5))

Expanding and simplifying this expression, we get:

[(x - 3) - i][(x - 3) + i][(x + 1 + √5)][(x + 1 - √5)]

Now, let's multiply the conjugate factors:

[(x - 3)² - i²][(x + 1)² - (√5)²]

Simplifying further:

[(x² - 6x + 9) + 1][(x² + 2x + 1) - 5]

Expanding and combining like terms:

(x² - 6x + 10)(x² + 2x - 4)

Finally, multiplying the binomials:

x⁴ - 4x³ - 6x² - 8x + 40

Therefore, the polynomial function with the given zeros x = 3 + i and x = -1 - √5 is:

f(x) = x⁴ - 4x³ - 6x² - 8x + 40

The area of each triangular face is:

Area = (1/2) * 10 ft * 6.9 ft ≈ 34.5 ft^2

To find the lateral roof area of the pentagonal pyramid, we need to calculate the area of each triangular face and then multiply it by the number of faces.

The lateral area of a triangular face can be calculated using the formula:

Area = (1/2) * base * height

In this case, the base of each triangular face is 10 feet (the length of each side of the pentagon) and the height is the slant height of the roof, which is approximately 6.9 feet.

Therefore, the area of each triangular face is:

Area = (1/2) * 10 ft * 6.9 ft ≈ 34.5 ft^2

Since there are 5 triangular faces on the pentagonal pyramid, the total lateral roof area is:

Total Area = 5 * 34.5 ft^2 = 172.5 ft^2

So, the correct answer is C. 172.5 ft^2.

A. If f is a factor of g, and g is a factor of h, then f is a factor of h.

B. In order to understand why the statement is true, let's consider the definitions of factors and divisibility.

If f is a factor of g, it means that g can be divided evenly by f without leaving a remainder.

Similarly, if g is a factor of h, it means that h can be divided evenly by g without leaving a remainder.

Now, if f is a factor of g and g is a factor of h, it implies that g can be divided evenly by f and h can be divided evenly by g.

Combining these two statements, we can conclude that h can also be divided evenly by f. Therefore, f is a factor of h.

This can be understood by considering the transitive property of divisibility. If a number x is divisible by another number y, and y is divisible by z, then x is also divisible by z.

In this case, f is divisible by g, and g is divisible by h, so f must also be divisible by h.

Therefore, the statement "f is a factor of h" must be true in this scenario.

To estimate the cost of a new 3000-ft² heat exchange system for a plant retrofit, we can use the price index and the information about the cost of a previous heat exchanger. Given that the price index 7 years ago was 1360 and is now 1478, and assuming a power-sizing exponent of 0.55, rough estimate for the cost of the new heat exchanger system is $77,700.

To estimate the cost, we need to account for the change in the price index over the years. The price index ratio is calculated as (new price index)/(old price index), which in this case is 1478/1360 = 1.085. Since the power-sizing exponent is 0.55, we raise the price index ratio to the power of 0.55, resulting in [tex]1.085^{0.55 {[/tex]≈ 1.036.

Next, we multiply the cost of the previous heat exchanger by this factor to estimate the cost of the new system. The cost of the previous heat exchanger was $75,000, so the rough estimate for the cost of the new heat exchanger system is approximately $75,000 × 1.036 ≈ $77,700.

It's important to note that this estimate is a rough approximation and does not account for other factors such as inflation or changes in technology. It serves as a starting point for estimating the cost of the new heat exchanger system based on the given information and assumptions.

The following statement is true: strong winds occur where isobars are closely spaced.

Isobars are lines on a weather map that connect points of equal atmospheric pressure. The spacing between isobars provides information about the pressure gradient, which is the change in pressure over a given distance. When isobars are closely spaced, it indicates a steep pressure gradient, which in turn leads to strong winds.

This is because air moves from areas of high pressure to areas of low pressure, and the greater the pressure difference, the faster the air will flow. Therefore, when isobars are closely spaced, it suggests a rapid change in pressure over a short distance, creating strong winds.

Regarding the other options:

- Isobars on a surface map are not necessarily drawn at 8mb intervals. The spacing between isobars can vary depending on the map and the purpose for which it is created.

- Atmospheric pressure increases towards the center of a high-pressure system, not a low-pressure system. In a high-pressure system, air descends and compresses near the surface, leading to higher pressure at the center.

- Atmospheric pressure decreases towards the center of a low-pressure system. In a low-pressure system, air rises and expands, causing lower pressure at the center.

Therefore, the true statement is that strong winds occur where isobars are closely spaced.

Let's assume that Wilfredo's current age is 42 years. According to the given information, Wilfredo is 8 years older than twice Alejandro's age.

Let's represent Alejandro's age as 'x'. Therefore, twice Alejandro's age would be 2x. According to the information, Wilfredo is 8 years older than twice Alejandro's age, so we can form the equation:

42 = 2x + 8

To find the value of 'x', we can subtract 8 from both sides of the equation:

The measure of the angle GEH in a rectangle EFGH, with vertices marked in order, is 33°.

By applying the basic properties of rectangles, we can easily figure out the solution to this problem.

Firstly, whenever a rectangle is mentioned in a question with its vertices, it should always be used in the order given. So, the rectangle EFGH means, the vertices go in the same order, in a clockwise direction. A random order of vertices would affect all measurements which are given or are to be taken later.

So, in the given rectangle, we see that EG AND FH are the diagonals, which can also be marked for the convenience of marking angles.

(The diagram has been given below for reference)

Since we have m∠FEG = 57° (read as 'the measure of angle FEG is 57 degrees'), we need to find the other angle associated with the same diagonal EG and vertex E.

We know that the angle at any vertex of a rectangle with its sides is a right angle, which is part of its basic property.

So, m∠FEH = 90°

But since ∠GEH and ∠GEF are co-joint,

m∠GEH + m∠GEF = m∠FEH

m∠GEH + 57° = 90°

m∠GEH = 90 - 57

m∠GEH = 33°

Thus, the measure of the angle ∠GEH is 33° in the rectangle.

To have $3,793,695.00 in his retirement account when he retires, Derek would need the rate on the account to be approximately 5.89%.

To calculate the required rate on Derek's retirement account, we can use the formula for the future value (FV) of an annuity:

[tex]FV = P * [(1 + r)^n - 1] / r[/tex]

Where:

FV is the desired future value

P is the amount deposited on each birthday

r is the interest rate per period

n is the total number of periods (number of birthdays)

In this case, the desired future value (FV) is $3,793,695.00, the amount deposited on each birthday (P) is $14,455.00, and the total number of periods (n) is the difference between Derek's final and initial birthday, which is 68 - 27 = 41.

We need to solve for the interest rate (r). Rearranging the formula:

[tex]r = [(FV / P) / [(1 + r)^n - 1]][/tex]

Substituting the given values, we have:

[tex]r = [(3,793,695.00 / 14,455.00) / [(1 + r)^{41} - 1]][/tex]

We can use numerical methods or trial and error to find the value of r that satisfies the equation. By using these methods, the approximate value of r is found to be 0.0589 or 5.89%.

Therefore, Derek would need the rate on his retirement account to be approximately 5.89% for him to have $3,793,695.00 in it when he retires.

To identify the coldest city in the United States, three different ways of selecting the coldest city could include looking at average annual temperature, average winter temperature, and record low temperatures.

When determining the coldest city based on average annual temperature, the city with the lowest average temperature throughout the year would be considered the coldest. This approach takes into account the overall temperature patterns and variations experienced by a city across all seasons.

Another method is to analyze the average winter temperature of different cities. Since winter is typically the coldest season, comparing the average temperatures during this time can help identify the coldest city. Cities with consistently low winter temperatures are more likely to be considered the coldest.

Lastly, examining the record low temperatures recorded in various cities can also provide insights into the coldest city. By considering the lowest temperatures ever recorded, we can identify the city that has experienced the most extreme cold conditions.

It's important to note that the coldest city in the United States may vary depending on the specific statistical measure used. While some cities may have the lowest average annual temperature, others might experience colder winters or have more extreme record low temperatures. Therefore, it's necessary to consider multiple factors and statistical measures when determining the coldest city.

Now,

We can use the Pythagorean theorem to find the length of the third side of the triangle:

[tex]a² + b² = c²[/tex]

where a is the length of the missing side.

we have b = 29 and c = 35.

So we have:

[tex]a² + 29² = 35²a² + 841 = 1225a² = 384[/tex]

a ≈ 19.6

So the length of the missing side is approximately **19.6** to the nearest tenth.

Now we can use trigonometry to find the angles. We know that sin(θ) = opposite/hypotenuse, cos(θ) = adjacent/hypotenuse, and tan(θ) = opposite/adjacent.

So we have:

sin(∠A) = a/c

sin(∠A) = 19.6/35

sin(∠A) ≈ 0.56

∠A ≈ 33.7°

cos(∠A) = b/c

cos(∠A) = 29/35

To write the function y = (9/4)x² + 3x - 1 in vertex form, we can complete the square. The vertex form of a quadratic function is given by y = a(x - h)² + k, where (h, k) represents the coordinates of the vertex.

Let's complete the square:

y = (9/4)x² + 3x - 1

y = (9/4)(x² + (4/3)x) - 1

To complete the square, we take half of the coefficient of x, square it, and add it inside the parentheses. However, since we multiplied the entire expression by (9/4), we need to multiply the added term by (9/4) as well.

y = (9/4)(x² + (4/3)x + (2/3)² - (2/3)²) - 1

The output of the code is:

f(a) =  4

f(a + h) =  52

difference quotient =  16.0

The difference quotient f(a+h)−f(a)/h, where h≠0.

f(x)=2−5x+3x²

* f(a) is found by substituting a for x in the function f(x).

* f(a + h) is found by substituting a + h for x in the function f(x).

* The difference quotient is found by evaluating f(a + h) - f(a) and dividing by h.

Here is the code to calculate the answers in Python:

```python

def f(x):

 return 2 - 5*x + 3*x**2

def main():

 a = 2

 h = 3

 f_a = f(a)

 f_a_h = f(a + h)

 difference_quotient = (f_a_h - f_a) / h

 print("f(a) = ", f_a)

 print("f(a + h) = ", f_a_h)

 print("difference quotient = ", difference_quotient)

if __name__ == "__main__":

 main()

* f(a) = 2 - 5a + 3a²

* f(a + h) = 2 - 5(a + h) + 3(a + h)²

* f(a + h) - f(a) / h = 16

To estimate the life span of a cat with a heart rate of 126 beats/min, we need to use the given data and the equation form r s = k, where r represents the heart rate, s represents the life span, and k is a constant.

From the table, we can identify pairs of heart rate and life span values. By observing the relationship between heart rate and life span, we can estimate the value of k. Once we have the value of k, we can substitute the given heart rate of 126 beats/min into the equation r s = k and solve for the life span, s.

However, without the specific data from the table or the value of k, I'm unable to provide a precise estimate or the exact expression to find the life span of a cat with a heart rate of 126 beats/min. If you could provide the necessary data or additional information, I would be able to assist you further in estimating the life span.

Answer:

4

Step-by-step explanation:

1/4 + 1/4 + 1/4 + 1/4 = 4/4 = 1

Helping in the name of Jesus.

Answer:

x² + y² = 10

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k ) = (0, 0 ) and r = [tex]\sqrt{10}[/tex] , then

(x - 0)² + (y - 0)² = ([tex]\sqrt{10}[/tex] )² , that is

x² + y² = 10
