Step-by-step explanation:

Answer: the range of g(x) is [0, 7]

Step-by-step explanation:

The domain is the set of the possible values of y.

We can see that, for y = f(x) in the domain [0, 50]

The smallest possible value of y is 0, and the largest possible value of y is 1.75 (at x = 25).

Then the range of f(x) is [0, 1.75]

Now, if we have the function g(x) = f(x)*4

Let's analyze the possible values of g(x) in these extremes of the range of f(x).

when f(x) is in the minimum, f(x) = 0, we have that g(x) is:

g(x) = f(x)*4 = 0*4 = 0.

So 0 is the minimum in the range of g(x).

Now, for the maximum of f(x) (f(x) = 1.75) we have:

g(x) = f(x)*4 = 1.75*4 = 7

Then the range of g(x) is [0, 7]

Answer:

The difference in energy production in kilowatt hours of monthly energy produced between an average local wind speed of 15 miles per hour and an average local wind speed of 10 miles per hour is approximately 9 kWh

Step-by-step explanation:

We note that the energy produced is given by the formula;

Energy = 1/2 × m × v²

From which we have the energy per unit mass = 1/2 × v²

The energy produced by the wind traveling at 15 miles per hour is given as follows;

15 mph = 6.705 m/s

The energy per unit mass produced in a month of 30 days is therefore;

1/2×6.705²×60×60×24×30 = 58264304.4 J/kg

We note that 1 Kilowatt hour = 3.6 × 10⁶ Joules

Therefore;

58264304.4 J = 58264304.4 J/(3.6 × 10⁶) kWh = 16.184529 kWh

The energy produced by the wind traveling at 10 miles per hour is given as follows;

10 mph = 4.47 m/s

The energy per unit mass produced in a month of 30 days is therefore;

1/2×4.47²×60×60×24×30 = 25,895,246.4 J/kg

We note that 1 Kilowatt hour = 3.6 × 10⁶ Joules

Therefore;

25,895,246.4  J = 25,895,246.4 J/(3.6 × 10⁶) kWh = 7.193124 kWh

The difference in energy production in kilowatt hours of monthly energy produced between an average local wind speed of 15 miles per hour and an average local wind speed of 10 miles per hour is therefore;

16.184529 kWh - 7.193124 kWh = 8.991405 kWh. ≈ 9 kWh

Step-by-step explanation:

[tex]3(n+1)=5.4[/tex]

Expand ; 3(n+1)

[tex]3(n+1) =3n +3\\\\3n+3 =5.4[/tex]

Collect like terms and simplify

[tex]3n =5.4-3\\3n=2.4[/tex]

Divide both sides of the equation by 3

[tex]\frac{3n}{3} = \frac{2.4}{3} \\\\n = 0.8[/tex]

Answer:

The value of n is 0.8 .

Step-by-step explanation:

First, you have to expand to get rid of brackets :

[tex]3(n + 1) = 5.4[/tex]

[tex]3n + 3 = 5.4[/tex]

Next, you have to subtract 3 on both sides to remove 3 at the left side :

[tex]3n + 3 - 3 = 5.4 - 3[/tex]

[tex]3n = 2.4[/tex]

Lastly, you have to divide 3 on both sides :

[tex]3n \div 3 = 2.4 \div 3[/tex]

[tex]n = 0.8[/tex]

Answer:

1. CA is defined

2. B^T * C^T defined

3. AC is NOT defined

4. A - B is defined

5. B - C is NOT defined

6. B^T is defined

Hence, 1,2,4, and 6 are defined

Step-by-step explanation:

Order of the matrices:

Matrix A is a (4 × 6) matrix  

Matrix B is a (4 × 6) matrix

Matrix C is a (7 × 4) matrix

To determine which are defined

1. CA

CA means product of Matrix C and Matrix A

To determine the product of two matrices, the number of columns in the first matrix must be equal to the number of rows in the second matrix. For example, given that matrix X is a (m × n) matrix, matrix Y is a (n × k) matrix and matrix Z is (k × n) matrix. From the definition above,

XY can be determined because number of columns in X equals number of rows in Y

XZ cannot be determine  because number of columns in X is not equal to the number of rows in Z.

YZ can be determined because number of columns in Y equals number of rows in Z

(NOTE: A matrix of order (m × n) means the matrix has m rows and n columns)

Hence, for CA

Matrix C is a (7 × 4) matrix

Matrix A is a (4 × 6) matrix

Number of columns in C equals number of rows in A, hence CA is defined

2. B^T * C^T

B^T means transpose of matrix B

Transpose of a matrix is defined as a new matrix whose rows are the same as the columns of the original matrix and whose columns are the rows of the original matrix. Hence, for a matrix of order (m × k), the transpose of the matrix will have an order (k × m).

Hence,

Matrix B is a (4 × 6) matrix

∴B^T gives a matrix of order (6 × 4)

Matrix C is a (7 × 4) matrix

∴ C^T gives a matrix of order (4 × 7)

Since the number of columns in B^T equals the number of rows in C^T, then  B^T * C^T defined

3. AC

Matrix A is a (4 × 6) matrix

Matrix C is a (7 × 4) matrix

The number of columns in A is NOT equal to the number of rows in C, hence AC is NOT defined

4. A - B

To find the difference between two matrices, the matrices must have the same order.

Matrix A is a (4 × 6) matrix  

Matrix B is a (4 × 6) matrix

Since matrices A and B have the same order [(4 × 6)], hence A - B is defined

5. B - C

Matrix B is a (4 × 6) matrix

Matrix C is a (7 × 4) matrix

Since matrices B and C are of different orders [(4 × 6) and (7 × 4) respectively], then B - C is NOT defined

6. B^T

B^T means the transpose of matrix B

Matrix B is a (4 × 6) matrix

From the above definition

B^T gives a (6 × 4) matrix

Hence, B^T is defined

Step-by-step explanation:

A set-builder notation describes or defines the elements of a set instead of listing the elements. For example, the set { 1, 2, 3, 4, 5, 6, 7, 8, 9 } list the elements. The same set could be described as { x/x is a counting number less than 10 } in set-builder notation.

Answer:

I believe it is the vertex, of an angle.

Step-by-step explanation:

It is the vertex, because that is what you would call the bottom point of an angle.

An angle is a figure created by two rays, known as the angles' sides, that share a common terminus, known as the angle's vertex. A point lies in the interior of an angle if it lies between the rays that form the angle.

An angle is a figure created by two rays, known as the angles' sides, that share a common terminus, known as the angle's vertex. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles.

An angle has two rays and the area that lies between the two rays is known as the interior of the angle, while the area that is not between the two rays is the exterior of the angle.

Therefore, A point lies in the interior of an angle if it lies between the rays that form the angle.

Answer:

B

Step-by-step explanation:

Answer:

larger number=29;smaller number=18

Step-by-step explanation:

let assume the two numbers are X and Y

where X is the larger number and Y is the smaller number.

From the question the larger number is 7 less than twice the smaller number. in mathematical terms this can be denoted as;

X=2Y - 7→→→→→→ equation 1

Also it was stated in the question that the sum of the two numbers is 47 which can be denoted as;

X + Y = 47→→→→→→ equation 2

Now from equation 1, X is mathematically expressed as 2Y - 7. Having known this we substitute X as 2Y - 7 into equation 2 then we have 2Y - 7 + Y = 47.

collecting like terms we have

2Y + Y = 47 + 7

solving arithmetically we have;

3Y = 54

divide both sides by 3 we have;

Y = 18.

Now if you recall from equation 1;

X = 2Y - 7;

since we now know Y as 18 we substitute Y as 18 in equation one then we have;

X = 2(18) - 7;

X =36 - 7

X = 29.

Inductive reasoning

Step-by-step explanation:

Inductive reasoning is when you make a false assumption based on previous knowledge you had before. The previous fact will often be referring to just a certain amount/set of things.

Deductive reasoning is when you have previous knowledge and you make a claim that is correct based on the knowledge before. The previous fact will often be referring to a whole set of things, not limited to a certain number.

The fact here is that Carrie's first three children were boys. This doesn't necessarily mean all of her upcoming children will be boys. So this is inductive reasoning.

Answer:

Sandy will receive $800

Steve will receive $600

Step-by-step explanation:

Sandy : Steve = 4 : 3

Sandy = 4

Steve = 3

Total ratio = 4 + 3 = 7

Total prize money = $1400

How much does Sandy receive ?

Sandy's share = Sandy's ratio / total ratio × Total prize money

= 4 / 7 × 1400

= 4 × 200

= $800

Sandy will receive $800 out of $1400

Steve's share = Steve's ratio / total ratio × Total prize money

= 3 / 7 × $1400

= 3 × $200

= $600

Steve will receive $600 out of $1400

Check:

Sandy's share + Steve's share

= $800 + $600

= $1400

Step-by-step explanation:

Answer:

The answer is 5 times

Step-by-step explanation:

First, we need to read the change in price in 2000 and 2007, from the graph.

So, the change in price in 2000 was $0.14 and in 2007 it was $0.71.

Now, we do the same thing we always do when comparing two values - we divide them. So:

0.71 / 0.14 = 5.07

Of course, we could multiply these values with 100, in order to avoid decimal numbers. Then we would get:

71 / 14 = 5.07

We could also divide this in the form of fractions:

71/100 / 14/100 = 5.07

There are several ways we could divide rational numbers, but the result will always be the same.

Change in price in 2007 was around 5 times greater than the change in 2000.

Answer:

The ring in 2020 costs around $3,931.2.

Step-by-step explanation:

We know how much the ring cost in 2018 and we know the percentages of the value as years go by.  

To solve this, we will need to put the percentages into decimals, and since we are adding value, add an additional 1 [whole] in both decimals.

Should look like this:

2019: 1.04

2020: 1.08

Multiply the cost with the first year:

3500 x 1.04 = 3640

The ring costs $3,640 in 2019.

Then it says the ring went up by %8 percent in 2020.

Multiply the cost from last year with the current year:

3500 x 1.08 = 3931.2

The ring costs $3,931.2 in 2020.

I hope this helps!
