In this problem, we have to complete the table by replacing v with each value from 0 to 6 in the table, and compute the corresponding value of s(v) based on the equation,

Find the values for the table,

UPS charges are:

$ 7 for the firsr pound

+ $0.20

FedEx charges are:

$ 5 for the first pound

+ $ 0.30 for each additional pound

Let x to represent the amount of additional pounds

Equation:

7 + 0.20x = 5 + 0.30x

Like terms:

0.20x - 0.30x = 5 - 7

-0.10x = -2

Dividing by -0.10

-0.10x/- 0.10 = -2/-0.10

x = 20

Interpretation

It will take 21 pounds to cost the same: (the first plus 20 additional)

Answer:

Step-by-step explanation:

$20/hr carpenter pay

$25/hr blacksmith pay

Let c = hours working carpentry

Let b = hours working as blacksmith

c + b = 30   {equation 1}

20c + 25b = 690   {equation 2}

In equation 1 solve for one variable in terms of the other.

c = 30-b

Substitute that into equation 2:

20(30-b) + 25b = 690

600 - 20b + 25b = 690

5b = 90

b = 90/5

b = 18 hours working as a blacksmith

c = 30-b = 30-18 = 12 hours as a carpenter

Answer:

she worked as a carpenter for 12 hours

And a blacksmith for 18 hours

Step-by-step explanation:

B=hours as blacksmith

C=hours as carpenter

20c+25b=690

b+c=30

c=30-b

So we substitute this into the first equation

20(30-b)+25b=690

 600-20b+25b=690

       5b=90

       B= 18

18+c=30

C=12

So first we have the expression "six times a number". Let's use x to designate the number, then this expression can be written as 6x. We are being told that this term is decresed by 2 which means that now we have 6x-2. Then we have a certain condition on the principal square root, this would be:

We are being told that this square root is equal to "3 less than the number". This last term can be written as x-3. Knowing that x-3 has to be equal to the square root I mentioned before we can build an equation for x:

Know let's find x. First I'm going to get rid of the square root by squaring both sides of the equation:

Know let's move all terms to the right side:

So we have a cuadratic function equalizing 0. This means that we can use the cuadratic formula:

Where a, b and c are the coefficients of the cuadratic equation.In this case a=1, b=-12 and c=11 so we have:

So we have two possible values for x, 1 and 11. Then the solution set is {1,11}

The limit as x approaches infinity of 4^x is of infinity, that is:

[tex]\lim_{x \rightarrow \infty} 4^x = \infty[/tex]

The first step in calculating the limit of a function is calculating the numeric value of the function at the value of x which the function approaches.

In this problem, the limit is given as follows:

[tex]\lim_{x \rightarrow \infty} 4^x = 4^{\infty} = \infty[/tex]

There is nothing undetermined, hence the value of limit is of infinity, as we calculated.

If an undetermined value such as 0/0 or infinity/infinity had been reached, then alternatives such as factorization or L'Hospital rule would be searched, but is not necessary in the context of this problem.

Hence, the limit is of infinity.

The volume of water that the cylindrical vase can hold is 10362 cm³.

Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units. Volume and the notion of length are connected.

The circumference of a cylindrical vase is 62.8 centimeters.

The height of the cylindrical vase is 33 centimeters.

Let r be the radius of the cylinder.

The circumference of the cylinder is given as:

C = 2πr

62.8 cm = 2 × 3.14 × r

r = 10 cm

The volume of a cylinder is given as:

V = πr²h where r is the radius and h is the height of the cylinder

Then,

V = 3.14 × ( 10 )² × 33

V = 10362 cm³

Hence, the cylindrical vase can hold 10362 cm³ of water.

C. Grapes are $0.48 per pound and oranges are $0.77 per pound.

The cost of grapes and oranges are 0.48 and 0.77 respectively.

Cost word problem

Evaluating cost of solution is simple: You determine the time and money you need to develop and implement it. You're looking at the resources needed. Cost of problem, however, equals the price of doing nothing. That is, for what I know, an important economic principle known from cost-benefit analyses.

Given that Peaches cost $4 for a 7-pound bag, grapes cost 15% less per pound than peaches, oranges cost 35% more per pound than peaches.

Cost of 7 pounds of peaches = 4

Therefore cost of 1 pound of peaches = 4/7 = 0.57

Cost of one pound of grapes = 0.57 - 15% of 0.57

                                                 = 0.57 - 0.0855

                                                 = 0.4845

                                                 = 0.48

Cost of one pound of oranges = 0.57 + 35% of 0.57

                                                   = 0.57 + 0.1995

                                                   = 0.7695

                                                   = 0.77

Therefore Grapes are $0.48 per pound and oranges are $0.77 per pound.

The amount in the account will be $8,878.56.

The amount of coffee imported into the country in the year 1997 is approximately 1.344 million pounds.

The amount of coffee imported into the country in the year 2002 is approximately 39.3176 million pounds.

The amount of coffee imported into the country in the year 2007 is approximately 85.8966 million pounds.

A polynomial function can be defined as a mathematical expression which comprises intermediates (variables), constants, and whole number exponents with different numerical value, that are typically combined by using mathematical operations such as:

Next, we would determine the amount of coffee imported into the country by using the given polynomial function as follows:

At 1997, we have the following:

x = 0

P(x) = 0.7166x² + 6.627x + 1.344

P(0) = 0.7166(0)² + 6.627(0) + 1.344

P(0) = 1.344 million pounds.

At 2002, we have the following:

x = 4

P(x) = 0.7166x² + 6.627x + 1.344

P(4) = 0.7166(4)² + 6.627(4) + 1.344

P(4) = 0.7166(16) + 26.508 + 1.344

P(4) = 11.4656 + 26.508 + 1.344

P(4) = 39.3176 million pounds.

At 2002, we have the following:

x = 9

P(x) = 0.7166x² + 6.627x + 1.344

P(9) = 0.7166(9)² + 6.627(9) + 1.344

P(9) = 0.7166(81) + 59.643 + 1.344

P(9) = 58.0446 + 26.508 + 1.344

P(9) = 85.8966 million pounds.

Answer:

The book has 175 pages

Explanation:

Andre says that he has read 1/5 of the book, so the correct diagram should have each rectangle label as a (the number of pages that Andre has read)

because 5 times 1/5 of the book makes the complete book.

On the other side, Elena has read 20 more pages than Andre, so we should have the second rectangle divided and one part should be label as 20 and the sum of a and 20 is equal to 55.

So, the correct diagram is:

Therefore, we can calculate the number of pages that Andre has read as:

a = 55 - 20 = 35

Then, the number of pages of the book is 5 times a, so:

5 x a = 5 x 35 = 175

Therefore, the answer is the book has 175 pages

Given the equation

To find a and b, you have to find the roots, following the steps below.

Let x represent the number of dimes Ed has in its collection.

The total of coins in the collection is 8 more than three times the number of dimes.

The number of coins is 92.

3 times the number of dimes can be symbolized as: 3x

"8 more" is symbolized as +8

So the total number of coins equals:

92=3x+8

From this expression you can determine the number of dimes by solving the equation for x:

x=28 → Ed has 28 dimes in his collection.
