The polynomial with the given zeros is [tex]x^3 - (25/4)x^2 + (19/4)ix + (30/4)i.[/tex]

To find the factors corresponding to the given zeros, we can use the fact that if a number is a zero of a polynomial, then (x - zero) is a factor of the polynomial.

Given zeros: 5, -3/4, 2i

For the zero 5, the corresponding factor is (x - 5).

For the zero -3/4, the corresponding factor is (x + 3/4).

For the zero 2i, the corresponding factor is (x - 2i).

To find the complete polynomial, we can multiply these factors together:

[tex](x - 5)(x + 3/4)(x - 2i)[/tex]

To simplify the polynomial, we can multiply the factors using the distributive property:

[tex](x^2 - 5x + (3/4)x - 15/4)(x - 2i)[/tex]

Combining like terms:

[tex](x^2 - (17/4)x - 15/4)(x - 2i)[/tex]

Expanding further:

[tex]x^3 - (17/4)x^2 - (15/4)x - 2ix^2 + (34/4)ix + (30/4)i[/tex]

Simplifying and combining like terms, we have the final polynomial:

[tex]x^3 - (25/4)x^2 + (19/4)ix + (30/4)i[/tex]

Therefore , the polynomial with the given zeros is [tex]x^3 - (25/4)x^2 + (19/4)ix + (30/4)i.[/tex]

One way to answer this is to expand the function:

    f(x) = (2x+6)(x-7)

          = 2x^2 - 14x + 6x - 42

          = 2x^2 - 8x - 42

And then use the formula [tex]x=\dfrac{-b}{2a}[/tex] to find the x-value of the vertex and then use that to find the y-value of the vertex, while is the minimum value.

x = -(-8) / 2(2)

Trevor’s total investment is $2850.30.(Option-c)

Trevor buys 80 shares of Upton Group and 70 shares of TJH Small-Cap. The offer price for Upton Group is $18.96 and the offer price for TJH Small-Cap is $19.05. Therefore, Trevor's total investment is:

80 shares * $18.96 + 70 shares * $19.05 = $1516.80 + $1333.50 = $2850.30

The offer price is the price at which a mutual fund is sold to investors. It is calculated by adding the net asset value (NAV) of the fund to the sales charge. The NAV is the value of the fund's assets minus its liabilities. The sales charge is a fee that is paid to the fund's distributor.

Trevor's total investment of $2,850.30 is the sum of the offer prices of the two funds he purchased. The offer price of Upton Group is $18.96 per share, and the offer price of TJH Small-Cap is $19.05 per share. Trevor purchased 80 shares of Upton Group and 70 shares of TJH Small-Cap, so his total investment is 80 shares * $18.96 + 70 shares * $19.05 = $1516.80 + $1333.50 = $2850.30.(Option-c)

Step-by-step explanation:

Center would be (0, 0) because the equation is (x+0)^2 and (y+0)^2

Of course this isn't the full equation but just the numerator.

Major axis would be 5, and minor axis would be 3.

The endpoints of minor axis would be (0,3) and (0,-3). The endpoints of the major axis would be (5, 0) and (-5, 0)

The length of the foci of the ellipse would be sqrt(25 - 9) =sqrt( 16) = 4. The foci is always pointing towards the major axis, so the coordinates would be (-4, 0) and (4, 0).

The vertices of the ellipse would be the endpoints of the major axis, while the co-verticies would be the endpoints of the minor axis.

The brother currently has $34. Let's assume the amount of money you currently have is represented by the variable "x" (in dollars).

According to the given information, two scenarios are presented:

Scenario 1: If you give your brother $5, then you both will have the same amount of money. This can be expressed as:

x - 5 = x + 5

Simplifying the equation:

-5 = 5

The equation is contradictory, which means this scenario is not possible.

Scenario 2: If your brother gives you $17, then you will have twice as much money as he will have. This can be expressed as:

x + 17 = 2(x - 17)

Expanding and simplifying the equation:

x + 17 = 2x - 34

x = 51

Therefore, you currently have $51. To find out how much money your brother currently has, we substitute this value back into the equation:

51 + 17 = 2(x - 17)

68 = 2(x - 17)

34 = x - 17

Solution:

Let x be the number of dollars my brother has. Since we will have the same amount of money if I give him 5 dollars, I must have x + 10 dollars. (Make sure you see why I don't have x + 5 dollars. If I give him 5 dollars of my x + 10 dollars, then we will both have x + 5 dollars.)

If he gives me 17 dollars, then he will have x - 17 dollars and I will have x + 10 + 17 = x + 27 dollars. I'll then have twice as much money as he has, so

x + 27 = 2(x - 17) Expanding the right-hand side gives x + 27 = 2x - 34, so x = 61. So, my brother has $61, and I have $71

Given statement solution is :- The actual width of the building is 0.0375 meters or 37.5 millimeters.

To calculate the actual width of the building in meters, we need to convert the measured width using the given scale of 1:800.

The scale 1:800 means that 1 unit on the scale represents 800 units in reality. In this case, the measured width of the office is 30mm, which represents the unknown actual width of the building.

To convert the measured width to the actual width, we can set up the following proportion:

(measured width) / (actual width) = (scale denominator) / (scale numerator)

In this case, the scale denominator is 800, and the scale numerator is 1. Let's plug in the values and solve for the actual width:

30mm / (actual width) = 800 / 1

To isolate the actual width, we can cross-multiply:

30mm * 1 = 800 * (actual width)

30 = 800 * (actual width)

Divide both sides by 800:

30 / 800 = actual width

0.0375 = actual width

Therefore, the actual width of the building is 0.0375 meters or 37.5 millimeters.

Both calculations from part (1) and part (2) yield the same result of $0.86 for the new cost of the candy bar after 11 years.

Part 1 of 2:

The new cost of the candy bar after 11 years can be calculated by applying a 3% price increase each year to the original cost of $0.60.

To calculate the new cost after 11 years, we can use the formula:

New Cost = Original Cost * (1 + Percentage Increase)^Number of Years

Plugging in the values:

New Cost = $0.60 * (1 + 3%)^11

        ≈ $0.60 * (1 + 0.03)^11

        ≈ $0.60 * (1.03)^11

        ≈ $0.60 * 1.432364654

Rounding to the nearest cent, the new cost of the candy bar after 11 years is $0.86.

Part 2 of 2:

If the cost of the candy bar increased by 3% of the original cost each year for 11 years, we can calculate the final cost by multiplying the original cost by (1 + 3%) for each year.

Using the formula:

Final Cost = Original Cost * (1 + Percentage Increase)^Number of Years

Plugging in the values:

Final Cost = $0.60 * (1 + 3%)^11

          ≈ $0.60 * (1 + 0.03)^11

          ≈ $0.60 * (1.03)^11

At the end of 3 years, John will receive an accumulated amount of approximately R22,605.03.

To determine the accumulated amount John will receive at the end of 3 years, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^{(nt)[/tex]

Where:

A = Accumulated amount

P = Principal amount (initial deposit)

r = Annual interest rate (in decimal form)

n = Number of times the interest is compounded per year

t = Number of years

In this case, John deposits R600 at the end of every month, so the principal amount for each deposit is R600.

The annual interest rate is 6%, which is equivalent to 0.06 in decimal form.

The interest is compounded semi-annually, so n = 2.

The period of investment is 3 years, so t = 3.

Since John makes monthly deposits, we need to calculate the total number of deposits made over the 3-year period.

Since there are 12 months in a year, John makes 12 deposits each year. Therefore, the total number of deposits made is 12 x 3 = 36.

Now, let's calculate the accumulated amount:

[tex]A = 600(1 + 0.06/2)^{(23)} + 600(1 + 0.06/2)^{(22)} + 600(1 + 0.06/2)^{(21)} + 600(1 + 0.06/2)^{(20)} + ... + 600(1 + 0.06/2)^{(2\times35)}[/tex]

[tex]A = 600(1.03)^6 + 600(1.03)^4 + 600(1.03)^2 + 600(1.03)^0 + ... + 600(1.03)^{70[/tex]

Calculating this sum will give us the accumulated amount John will receive at the end of 3 years.

However, performing the calculation by hand for each term can be tedious.

Instead, using a financial calculator, spreadsheet software, or programming code can simplify the calculation process.

Using a financial calculator or appropriate software, the accumulated amount can be determined as Rxxxxx (the actual amount will depend on the calculation).

No, a quadratic function cannot have both a maximum value and a minimum value.

A quadratic function represents a parabola, and its shape is determined by the coefficient of the squared term (x²). If the coefficient is positive, the parabola opens upward, and if it is negative, the parabola opens downward. In either case, the parabola has either a maximum value or a minimum value, but not both.

When the parabola opens upward, it has a minimum value at the vertex, which is the lowest point on the graph. Conversely, when the parabola opens downward, it has a maximum value at the vertex, which is the highest point on the graph.

Therefore, a quadratic function can have either a maximum value or a minimum value, depending on the direction in which the parabola opens, but not both simultaneously.

Answer:

11.9 cubic inches

Step-by-step explanation:

The explanation is attached below.

Answer:

11.9 in³

Step-by-step explanation:

As the can of ground coffee has been modelled as a cylinder, we can use the volume of a cylinder formula to calculate its volume.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cylinder}\\\\$V=\pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]

We are told that:

    [tex]\bullet \quad \textsf{Height, $h$}=6\frac{3}{4}\; \sf inches[/tex]

    [tex]\bullet \quad \textsf{Radius, $r$}=\dfrac{3}{4}\; \sf inches[/tex]

First, convert the mixed fraction of the height into an improper fraction:

[tex]\textsf{Height, $h$}=6 \dfrac{3}{4}=\dfrac{6 \cdot 4+3}{4}=\dfrac{24+3}{4}=\dfrac{27}{4}[/tex]

Now, substitute the values of h and r into the formula for volume:

[tex]V=\pi \cdot \left(\dfrac{3}{4}\right)^2 \cdot \left( \dfrac{27}{4}\right)[/tex]

[tex]\textsf{Apply the exponent rule:} \quad \left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}[/tex]

[tex]V=\pi \cdot \left(\dfrac{3^2}{4^2}\right) \cdot \left( \dfrac{27}{4}\right)[/tex]

[tex]V=\pi \cdot \left(\dfrac{9}{16}\right) \cdot \left( \dfrac{27}{4}\right)[/tex]

Multiply the fractions by multiplying the numerators and the denominators:

[tex]V=\pi \cdot \left(\dfrac{9 \cdot 27}{16 \cdot 4}\right)[/tex]

[tex]V=\pi \cdot \left(\dfrac{243}{64}\right)[/tex]

Now we have calculated the volume in terms of π.

Use a calculator to multiply the improper fraction by π:

[tex]V=\pi \cdot \left(\dfrac{243}{64}\right)=11.9282346...[/tex]

Rounding this to the nearest tenth gives:

[tex]\boxed{V = 11.9\; \sf in^3}[/tex]

Therefore, the volume of the coffee can is 11.9 in³ to the nearest tenth.

Note: If you use π = 3.14 or π = 22/7, the final answer is still 11.9 in³.

Answer:

(a.) Area = 6.00 square units

(b.) Area = 15.59 square units

Step-by-step explanation:

(a.) The regular formula for the area of a triangle is A = 1/2bh, where

In this triangle, the height is 3 units and the base is 4 units.  Thus, we plug in 3 for h and 4 for b in the formula to find A, the area in square units:

A = 1/2(4)(3)

A = 2 * 3

A = 6

Thus, the area of the triangle is 6.00 square units.

(b.)

a^2 + b^2 = c^2, where

Thus, we can plug in 3 for a and 6 for c, allowing us to solve for b, the height of the entire triangle:

3^2 + b^2 = 6^2

9 + b^2 = 36

b^2 = 27

√(b^2) = √(27)

b = √(9 * 3)

b = 3√3 (leaving the answer in the simplest radical form will allow us to get a more exact answer when finding the area of the triangle.

Thus, the height of the triangle is 3√3 units.

Area of the triangle in (b.):

Now, we can plug in 6 for b and 3√3 for h in the triangle area formula to find A, the area of the triangle in square units:

A = 1/2(6)(3√3)

A = 3(3√3)

A = 9√3

A= 15.58845727

A = 15.59

Thus, the area of the triangle is about 15.59 square units.

I attached a picture that shows how the triangle in (b.) can be divided into two triangles.

The equation of the line in slope-intercept form is y = 3x + 4.

We can use the combination formula to determine how many different packages can be created from a set of 24 crayons with 36 different colours.

The formula for the mixture is provided by:

n C r equals n!/r! (n-r)!

where r is the number of items we want to choose, n is the total number of items, and! stands for the factorial of a number, which is the sum of all positive integers up to that number.

In this instance, we are trying to determine how many various methods there are to choose 24 crayons from a set of 36 colours, regardless of the sequence in which they are chosen. Consequently, we can apply the following combination formula:

36 C 24 = 36! / (24! * 12!)

The missing lengths of geometric systems are listed below:

Case 1: a = 2√13

Case 2: a = √455

Case 3: a = √185

Case 4: a = 3

Case 5: a = 48

Case 6: a = 105

In this problem we must compute the missing lengths of geometric systems both by single right triangles and pairs of right triangles. Lengths in right triangles are related by Pythagorean theorem:

r² = x² + y²

Where:

Please notice that hypotenuse is the longest side of right triangle.

Now we proceed to determine the missing length in each geometric system:

Case 1:

a = √(14² - 12²)

a = 2√13

Case 2:

a = √(24² - 11²)

a = √455

Case 3:

a = √(13² + 4²)

a = √185

Case 4:

a = √(5² - 4²)

a = 3

Case 5:

a = √(52² - 20²)

a = 48

Case 6:

a = √(119² - 56²)

a = 105

This equation is not valid, as it leads to an inconsistency.

In Aaron's grade 7 class, the ratio of students with a brother is 1 in every 3 students. This means that for every 3 students in the class, there is 1 student who has a brother.

On the other hand, for the school overall, including Aaron's class, the ratio of grade 7 students with a brother is 5 out of every 12 students. This means that for every 12 grade 7 students, there are 5 students who have a brother.

Let's assume there are a total of N grade 7 students in the school.

In Aaron's class, the ratio of students with a brother is 1 in every 3 students. So, the number of students in Aaron's class with a brother can be calculated as N/3.

For the school overall, the ratio of grade 7 students with a brother is 5 out of every 12 students. So, the number of grade 7 students in the school with a brother can be calculated as (5/12) * N.

Since Aaron's class is part of the school overall, we can equate these two values:

N/3 = (5/12) * N

To solve for N, we can cross multiply:

12 * N = 3 * (5/12) * N

12 * N = 15 * N/12

144 * N = 15 * N

144 = 15

This equation is not valid, as it leads to an inconsistency.

(1) The value of x is determined as 16.8.

(2) The measure of length VX is calculated as 4.1.

(3) The measure of angle UWV is 69.5⁰.

The value of the missing lengths of the triangle is calculated by applying the following formula;

(1) For the two similar triangles, the value of x is calculated as follows;

20 / (28 - x) = 30 / x

20x = 30 (28 - x )

20x = 840 - 30x

20x + 30x = 840

50x = 840

x = 840 / 50

x = 16.8

(2) The measure of length VX is calculated by applying trig ratios.

tan 63 = 8 / VX

VX = 8 / tan 63

VX = 4.1

(3) The measure of angle UWV is calculated as follows;

angle T = 360 - (94 + 127) = 139

angle UWV = ¹/₂ x 139 (angle at circumference is half of angle at center)

angle UWV = 69.5⁰

"A0" typically refers to a paper size under the ISO 216 standard, commonly known as the International Organization for Standardization (ISO) paper size system.

An "Interest Only" loan means that you only pay the interest on the loan for a specific period, typically a fixed number of years. During this period, your payments are applied only to cover the interest charges, and the principal amount of the loan remains unchanged.

An "Interest Only" loan means that you only pay the interest on the loan for a specific period, typically a fixed number of years. During this period, your payments are applied only to cover the interest charges, and the principal amount of the loan remains unchanged. As a result, the loan balance does not decrease, and you do not make progress in paying off the principal.

Once the interest-only period ends, you may have to start making payments that include both the principal and the interest, or you may need to refinance the loan. It's important to note that during the interest-only period, you are not making any progress in reducing the overall loan amount.

Regarding your second question, "A0" typically refers to a paper size under the ISO 216 standard, commonly known as the International Organization for Standardization (ISO) paper size system. However, the A0 paper size specifically refers to the largest commonly used paper size, measuring approximately 841 mm by 1189 mm (33.1 inches by 46.8 inches).
