The zeros of the function H(x) = (3x - 4)(x + 2)^2(x - 5) are (4/3, 0), (-2, 0), and (5, 0).

To find the zeros of the function H(x), we need to find the values of x that make the function equal to zero.

H(x) = (3x - 4)(x + 2)^2(x - 5)

Setting H(x) equal to zero, we have:

(3x - 4)(x + 2)^2(x - 5) = 0

Using the zero product property, we can see that H(x) will be equal to zero when any of the factors are equal to zero.

So, the zeros of the function H(x) are:

3x - 4 = 0, which gives x = 4/3

x + 2 = 0, which gives x = -2

x - 5 = 0, which gives x = 5

Therefore, the zeros of the function H(x) are (4/3, 0), (-2, 0), and (5, 0).

Derivatives are the fundamental tools of calculus. Differentiation (the rate of change of a function with respect to a variable in mathematics) (in mathematics, the rate of change of a function with respect to a variable). The use of derivatives is essential in the solution of calculus and differential equation problems. The definition of "derivative" or "taking a derivative" in calculus is finding the "slope" of a certain function. Because it is frequently the slope of a straight line, it should be enclosed in quotation marks. Derivatives are rate of change metrics that apply to almost any function.

The amount Elsa earns per week, which is $150 more than Anna per week and Elsa had saved $2400 more than Anna when Anna had saved $2880, found by solving the simultaneous equations obtained is $650.

Simultaneous equations are equations that share the same variables.

Let x represent the amount Elsa earn per week, we get;

The amount Anna earns per week + 150 = The amount Elsa earns per week

Therefore; The amount Anna earns per week = x - 150

The amount each girl spent per week = $320

The amount saved per week = The rest of their weekly earning

The mount more Elsa add saved when Anna saved $2880 = $2400

Let n represent the number of weeks after which Anna had saved $2,880, we get the following equations;

n × (x - 150 - 320) = 2800

n × (x - 470) = 2800...(1)

n × (x - 320) = 2880 + 2400 = 5280

n × (x - 320) = 5280...(2)

The above simultaneous equations (1) and (2) indicates;

n × (x - 470) = 2800

x - 470 = 2880/n

x = 2880/n + 470

n × (x - 320) = 5280

x - 320 = 5280/n

x = 5280/n + 320

2800/n + 470 = 5280/n + 320

5280/n - 2880/n = 470 - 320 = 150

(5280 - 2880)/n = 150

n = (5280 - 2880)/150 = 16

n = 16

x = 5280/n + 320

B) the graph is attached accordingly.

C) In the context of the given problem, to store 43 liters of coffee, she needs at least 8 dispensers, as given by the function D(L).

a) To complete the table, we need to use the given function D(L) to determine the number of beverage dispensers needed to hold different amounts of coffee.

We know that each beverage dispenser can hold 6 liters of coffee, so we can start by dividing the amount of coffee needed by 6 and rounding up to the nearest integer to get the number of dispensers needed.

D(L) = ceil(L/6)

Using this formula, we can complete the table as follows:

Note that for L=0, we don't need any dispensers, so the value of D(L) is 0. For all other values of L, we divide by 6 and round up to get the corresponding value of D(L).

b) The graph is attached.

c) In the context of the given problem, the function D(L) gives the minimum number of beverage dispensers needed to hold L liters of coffee, assuming each dispenser can hold 6 liters.

So, D(43) = 8 means that if Giada needs to brew and store 43 liters of coffee, she will need at least 8 beverage dispensers. Each dispenser can hold 6 liters, so the first 7 dispensers will be completely filled, and the last dispenser will be partially filled with the remaining coffee.

In other words, if Giada fills 7 dispensers completely, she will have used 42 liters of coffee, and the remaining 1 liter of coffee will be stored in the 8th dispenser. Therefore, to store 43 liters of coffee, she needs at least 8 dispensers, as given by the function D(L).

Answer:

Step-by-step explanation:

Eva is not correct. There is only one possible triangle that can be formed with the given information. This is because in a triangle, the length of any side must be less than the sum of the lengths of the other two sides.

Using the Law of Cosines, we can find the length of the unknown side, c:

c^2 = a^2 + b^2 - 2ab cos(ZA)

c^2 = 54^2 + 59^2 - 2(54)(59) cos(130°)

c ≈ 31.28

Since h < a < b, we know that h < 54 < 59. Therefore, the length of side c must be between 5 and 113 (59 - 54 and 59 + 54). Since c = 31.28 is between 5 and 113, it satisfies the triangle inequality and a triangle can be formed.

To find the measures of the other angles, we can use the Law of Sines:

sin(A)/a = sin(ZA)/c

sin(A) = (a/c)sin(ZA)

sin(A) = (54/31.28)sin(130°)

sin(A) ≈ 0.879

A ≈ 62.6°

Similarly,

sin(B)/b = sin(ZA)/c

sin(B) = (b/c)sin(ZA)

sin(B) = (59/31.28)sin(130°)

sin(B) ≈ 0.841

B ≈ 56.2°

Therefore, the measures of the three angles are approximately 62.6°, 56.2°, and 61.2°, and there is only one possible triangle that can be formed with these side lengths and angle measures.

The value of the limit of the expression Limit x tend to π 1-sinx/2(π-x) ² is infinity (∝)

Given that

Limit x tend to π 1-sinx/2(π-x) ²

To solve this expression, we make use of

If limit of x to a+ of f(x) = limit of x to a- = L, then limit of x to a+ of f(x) = L

The interpretation is that we solve the expression by direct substitution

So, we have

Limit = 1 - sin(π)/2(π - π) ²

Evaluate the difference

Limit = 1 - sin(π)/2(0)²

The predicted Iife expectancy οf maIes in 2006 is 71.7 years.

A Iinear equatiοn is a mathematicaI equatiοn that describes a straight Iine in a twο-dimensiοnaI pIane.

Tο find the Iinear functiοn E(t) that fits the data, we need tο find the equatiοn οf the Iine that passes thrοugh the twο given pοints: (0, 65.2) and (5, 67.7), where t = 0 cοrrespοnds tο the year 1993 and t = 5 cοrrespοnds tο the year 1998.

Using the sIοpe-intercept fοrm οf a Iinear equatiοn, we have:

E(t) = mt + b

where m is the sIοpe οf the Iine and b is the y-intercept.

We can find the sIοpe by using the fοrmuIa:

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

where (x1, y1) = (0, 65.2) and (x2, y2) = (5, 67.7):

m = (67.7 - 65.2)/(5 - 0) = 0.5

Sο the equatiοn οf the Iine is:

E(t) = 0.5t + b

Tο find the y-intercept, we can use οne οf the given pοints. Let's use (0, 65.2):

65.2 = 0.5(0) + b

b = 65.2

Therefοre, the Iinear functiοn E(t) that fits the data is:

E(t) = 0.5t + 65.2

Tο predict the Iife expectancy οf maIes in 2006, we need tο find t when the year is 2006:

t = 2006 - 1993 = 13

Sο we can use t = 13 in the equatiοn:

E(13) = 0.5(13) + 65.2

E(13) = 6.5 + 65.2

E(13) = 71.7

To find the number of miles at which the cost to rent either car would be the same, we can set the two cost equations equal to each other and solve for m:

0.60m + 10 = 0.40m + 22

0.20m = 12

m = 60

So, the number of miles at which the cost to rent either car would be the same is 60 miles.

To find the cost at this mileage, we can plug m = 60 into either of the cost equations:

For the compact car:

C = 0.60(60) + 10 = 46

For the midsized car:

C = 0.40(60) + 22 = 46

So, at 60 miles, the cost to rent either car would be $46.

So the three integers are 4, 6, and 8 such that 6 times the first integer is 10 more than the sum of the second and the third integers.

An integer is a whole number that does not have any fractional or decimal parts. Integers include positive numbers (1, 2, 3, etc.), negative numbers (-1, -2, -3, etc.), and zero (0).

Here,

Let's call the first even integer x. Since the three integers are consecutive even integers, the second and third integers are x + 2 and x + 4, respectively.

From the problem statement, we know that:

6x = (x + 2) + (x + 4) + 10

Simplifying the right side of the equation:

6x = 2x + 16

Subtracting 2x from both sides:

The student can purchase no more than four books, or k. This can be represented so the correct answer option (A) is  8.50k +2.25(k+ 4) ≤ 43

Symbol for inequality: Comparing two numbers that are not equal requires the use of an inequality symbol. (>) More Than: The larger number is always on the left when using this symbol, and the smaller number is always on the right.

First, let's define some variables. Let b be the quantity of books the student purchases, and p represent the quantity of pens. Since the student purchases four more pens than books, the total cost of the purchase is $43, and we know that p = b + four. This can be expressed as an equation:

8.50b + 2.25p = 43

By replacing p = b + 4, we obtain:

8.50b + 2.25(b + 4) = 43

If we simplify, we get:

10.75b + 9 = 43

9 is subtracted from either side, resulting in:

10.75b = 34

By multiplying both sides by 10.75, we obtain:

b ≈ 3.16

The student may purchase either 3 or 4 books because the total number of books must be a whole number. Let's use the initial equation to verify these values:

If the student purchases three books, then p = 3 + 4 = seven pens are needed. 8.50(3) + 2.25(7) = 38.25, or less than $43, is the total price.

If the student purchases four books, then p = four plus four equals eight pens. 8.50(4) + 2.25(8) = 43, or precisely $43, is the total price

As a result, the student can purchase no more than four books, or k. This can be represented as:

8.50k + 2.25(k + 4) ≤ 43

Answer:

The first term of the sequence is -3 and the common difference is -1/3. Therefore, the second term of the sequence can be found by adding the common difference to the first term:

second term = first term + common difference

second term = -3 + (-1/3)

second term = -10/3

Similarly, we can find the third term by adding the common difference to the second term:

third term = second term + common difference

third term = -10/3 + (-1/3)

third term = -11/3

And we can find the fourth term by adding the common difference to the third term:

fourth term = third term + common difference

fourth term = -11/3 + (-1/3)

fourth term = -4

Therefore, the first four terms of the sequence are -3, -10/3, -11/3, and -4.

Answer:

Rusty Raspberry's total earnings last year would be the sum of his earnings from playing baseball and his earnings from book royalties.

Earnings from playing baseball = $1,715,000

To calculate earnings from book royalties, we need to find out how much Rusty received in royalties for the 300,000 copies sold.

Royalties per book = 10% of $24 = $2.40

Total royalties for 300,000 books = $2.40 x 300,000 = $720,000

Therefore, Rusty Raspberry's earnings from book royalties last year = $720,000

Total earnings = Earnings from playing baseball + Earnings from book royalties

= $1,715,000 + $720,000

= $2,435,000

Therefore, Rusty Raspberry's total salary last year from the book and his baseball career was $2,435,000.

Each interior angles of the rectangle QUAD is equal to 90°, and the angles ∠2 and ∠5 are complementary, so the value of x = 4.

The angles ∠2 and ∠5 form one of the interior angles of a rectangle, hence they are complementary as they add up to 90°.

we shall solve for x as follows:

x + 30 + 2x - 48 = 90

3x + 78 = 90

3x = 90 - 78 {subtract 78 from both sides}

3x = 12

x = 12/3 {divide through by 3}

Assuming the bag of dog food is a large bag and Carl is feeding his dog 2 1/2 cups daily, the maximum number of days Carl can feed his dog from one full bag is 28.
This is because 2 1/2 cups equals 20 cups per week, and a large bag typically contains approximately 560 cups.
Therefore, 560 cups divided by 20 cups per week equals 28 weeks.

The entire number of kilometres driven by Roland's family can be determined by using the phrase [tex]=\frac{69}{10}[/tex]

To determine the total number of kilometres driven by Roland's family, the distance from their home to the gas station and the distance from the gas station to the shop must be added.

There are [tex]4\times \frac{6}{10}[/tex] kilometres between their home and the gas station, which can also be stated incorrectly as follows:

[tex]4\times \frac{6}{10}=\frac{(4\times 10+6)}{10} \\\\=\frac{46}{10}[/tex]

The formula for expressing the distance between the gas stop and the store is 2 30/100 kilometers, which can be written as follows:

[tex]2\times\frac{30}{100} =\frac{(2\times100+30)}{100} \\\\=\frac{230}{100}[/tex]

To calculate the overall distance traveled, we add the two distances:

[tex]\frac{46}{10} +\frac{230}{100}[/tex]

To combine these fractions, we need to find a common denominator. Only one unique digit, 100, can be used to divide both 10 and 100. In light

of this, we can rewrite the equation as follows using 100 as the common denominator:

[tex](\frac{46}{10} )\times (\frac{10}{10} )+(\frac{230}{100} )\times (\frac{1}{1} )[/tex]

That amounts to:

[tex]\frac{46}{100} +\frac{230}{100} =\frac{690}{100}[/tex]

Therefore, we can reduce this fraction by multiplying the numerator and denominator by their ten largest common factor:

[tex]\frac{690}{100} =\frac{(69/10)}{(100/10)} \\\\=\frac{69}{10}[/tex]

Consequently, the phrase that follows may be used to determine the overall number of kilometres driven by Roland's family:

[tex]2\times\frac{30}{100} +4\times \frac{6}{10} =\frac{69}{10}\ km[/tex]

Rest of the question is,

They drove 2 30/100 kilometers from the gas station to the store. Which expression can be used to determine the number of kilometer Ronald's family drove altogether.

Answer:

Step-by-step explanation:

modal weight:  the weight that appear most often

4.5 kg  appears 3 times

6-sided polygon:  even though it is an irregular polygon, the interior angles still add up to (6 - 2)180 = 720

therefore, angle f = 720 - 576 = 144      (the sum of a+b+c+d+e is very blurry in the image, it looks like 576--please double check that!)

modal score:  read this right off the graph.  The score with the highest frequency is the modal score:  14   (meaning, 9 contestants got this score)
