The functions that have a range of all real numbers include the following:

Option 1; f(x) = -x + 2

Option 3; [tex]h(x) = 2^x +1[/tex]

In Mathematics and Geometry, a range can be defined as the set of all real numbers that connects with the elements of a domain.

Additionally, the vertical extent of any graph of a function represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following range for f(x) and h(x):

Range = {-∞, ∞}, y|y ∈ R, or all real numbers.

Answer:

21 and 42

Step-by-step explanation:

Lets say x and y are our numbers. x is the smaller number, y is the larger.

We can construct the equations:

x = 0.5y

x + y = 63

Substitute 0.5y for x in the second equation.

0.5y + y = 63

1.5y = 63

y = 42.

Plug y into the first equation.

x = 0.5 * 42

x = 21.

Your numbers are 21 and 42.

Answer:

36°

Step-by-step explanation:

x+27+27+90=180

The explicit rule for the geometric sequence with a recursive rule of a1=4/9 and an=3an-1 is: an = (4/9) * (3)^(n-1)

To find the explicit rule for a geometric sequence, we use the formula:

an = a1 * r^(n-1)

where a1 is the first term, r is the common ratio, and n is the term number.

Given the recursive rule for this geometric sequence as a1=4/9 and an=3an-1, we can find the common ratio:

an = 3an-1

an/an-1 = 3/1

r = 3

Now we can use the formula to find the explicit rule:

an = a1 * r^(n-1)

an = (4/9) * (3)^(n-1)

Therefore, the explicit rule is: an = (4/9) * (3)^(n-1)

To find out how many total miles Mario swam in the first week of training, we need to add up the distances he swam each time:

3/5 + 3/5 + 3/5 + 9/10 + 9/10 + 23/25 + 23/25

To add these fractions, we need to find a common denominator. The smallest common multiple of 5, 10, and 25 is 50.

3/5 = 30/50

9/10 = 45/50

23/25 = 46/50

Now we can add the fractions:

30/50 + 30/50 + 30/50 + 45/50 + 45/50 + 46/50 + 46/50

= (30 + 30 + 30 + 45 + 45 + 46 + 46)/50

= 272/50

= 5.44

Therefore, Mario swam a total of 5.44 miles in the first week of training.

The LCD of the rational equation above is 4(x + 7)(x - 7).

To find the LCD (Least Common Denominator) of the given rational equation, we need to factor the denominators of each fraction and then take the product of the highest powers of each factor.

The first denominator, x^2 - 49, can be factored using the difference of squares formula:

x^2 - 49 = (x + 7)(x - 7)

The second denominator, 4x + 28, can be factored by factoring out the greatest common factor:

4x + 28 = 4(x + 7)

Therefore, the LCD is the product of the highest powers of each factor, which is:

LCD = 4(x + 7)(x - 7)

So we need to multiply each term in the equation by an appropriate form of 1 so that the denominators of all the fractions become the LCD, 4(x + 7)(x - 7).

The inequality represent the given graph is y≤1.4x+2.5.

From the graph, the line passes through (0, 2.5) and (3.5, 0).

Here, slope (m) = (3.5-0)/(2.5-0)

= 3.5/2.5

= 1.4

Substitute m=1.4 and (x, y)=(0, 2.5) in y=mx+c, we get

2.5=1.4(0)+c

c=2.5

So, the equation of a line is y=1.4x+2.5

So, the inequality is y≤1.4x+2.5

The vector v can be expressed as v = -0.161 i + 0.618 j, where i and j are the unit vectors

To express a vector v in terms of i and j, we need to find its x and y components. The magnitude ||v|| of a vector is given by:

||v|| = √(v₁² + v₂²)

where v₁ and v₂ are the x and y components of v, respectively.

The direction angle θ of a vector with respect to the positive x-axis is given by:

θ = atan(v₂/v₁)

where atan denotes the arctangent function.

In this problem, we are given that the magnitude ||v|| of the vector v is 2/3, and its direction angle θ with respect to the positive x-axis is 116 degrees. Therefore, we can write:

||v|| = √(v₁² + v₂²) = 2/3

θ = atan(v₂/v₁) = 116°

Solving for the x and y components, we get:

v₁ = ||v|| cos(θ) = (2/3) cos(116°) ≈ -0.161

v₂ = ||v|| sin(θ) = (2/3) sin(116°) ≈ 0.618

Therefore, the vector v can be expressed as:

v = -0.161 i + 0.618 j

Answer:

When you divide 781.253 by 100, you get 7.81253 as the result.

The digit 2 is in the hundredths place in the dividend 781.253. Since we are dividing by 100, which has two decimal places, we move the decimal point two places to the left in the dividend to get the quotient.

Therefore, the digit 2 is in the ten-thousandths place in the quotient 7.81253.

The array that represents the total number of miles is X = 12

Given that;

Selena ran 4 miles per day

And she ran for 3 different days

Let the total miles she ran = X

therefore

X =  miles of 1st day  + miles of 2nd day  + miles of 3rd day

⇒ X = 4 + 4 + 4

⇒ X = 12 miles

The equation of the line that is parallel to the line that passes through the point (7, 6) is y = 8x - 50.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature.

Since lines can exist embedded in two, three, or higher dimensions environments, they are one-dimensional objects.

The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.

So, the lines with the same slope but a different y-intercept are said to be parallel.

Therefore, we must use the same slope to plug in the point (7, 6) and solve for the y-intercept.

We thus have:

y = 8x + b

6 = 8(7) + b

6 = 56 + b

b + 56 = 6

b + 56 - 56 = 6 - 56

b = -50

The equation is: y = 8x - 50

Therefore, the equation of the line that is parallel to the line that passes through the point (7, 6) is y = 8x - 50.

Consider the line y = 8x - 4. Find the equation of the line that is parallel to this line and passes through the point (7, 6).

Answer:

Option C

Step-by-step explanation:

To solve this system of equations, we can use the method of elimination. Adding the two equations together eliminates the y variable, and we get:

2x = 6

Simplifying, we get:

x = 3

Substituting x = 3 into either of the original equations, we get:

3 + y = -4

Mean weekly earnings = (971) / (1) = $971

For Manufacturing:

Mean weekly earnings = (977) / (1) = $977

An equation of the linear function represented by the graph in slope-intercept form is y = 3x + 60.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (75 - 60)/(5 - 0)

Slope (m) = 15/5

Slope (m) = 3

At data point (0, 60) and a slope of 3, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 60 = 3(x - 0)  

y = 3x + 60

Tthe reserve rate was approximately 0.9434, or 94.34%.

This is a geometric series with first term 3000r and common ratio (1-r), so we can use the formula for the sum of a geometric series:

sum = a(1 - r^n) / (1 - r)

where a = 3000r is the first term.

As the cycle continues indefinitely, the amount loaned out eventually becomes the final amount of $50,000. Therefore:

3000r/(1-r) = 50,000

Solving for r, we get:

r = (50,000)/(3000 + 50,000) = 0.9434
