What is the domain of a function?

The domain of a function is the set of all input values (also known as the independent variable) for which the function produces a valid output (also known as the dependent variable). In other words, it is the set of all input values for which the function is defined.

The situation described is discrete data.

The domain or set of all possible x-values for this situation would be the set of non-negative integers (x = 0, 1, 2, 3, ...) since the cost of each song is $3.00 and Clarissa can only buy a whole number of songs, not a fraction or decimal of a song.

Hence, the situation described is discrete data and the domain would be {x E Z | x >=0} where Z represents the set of integers and x is greater or equal to 0.

Answer: X = 88, Y = 26, Z = 11.2

Step-by-step explanation:

First thing is use any linear pair equation that only has one variable.

1. 2x-30 + 34 = 180, Y = 88

Plug in the value of X to a two-variable equation to find the value of y.

2. 2y +88 + 40 = 180, Y = 26

Lastly repeat this step for finding the value of z.

3. 88 + 39 + 5z - 3 = 180, Z = 11.2

Answer: x = 88, y = 26, z = 26

Step-by-step explanation:

The shape shown in the picture is a heptagon.

Sum of interior angle = 900 degrees

Add all the interior angles

x+40+x+22+142+x+39+133+2x-30+114

=5x+460

5x+460=900

5x = 440

x = 88

2y is the exterior angle of x+40

to get 2y, you need to subtract x+40 from 180.

x = 88,

x+40 = 128

2y = 180-128 = 52

y = 26

5z-3 is the exterior angle of x+39

same thing for 5z-3

x = 88,

x+39 = 127

5z-3 = 127

5z = 130

z = 26

The integral represents a graph of the signed area, and the geometry is calculated. The area is found to be 100 units².

A plane that is created when two perpendicular coordinate axes cross each other is known as a cartesian plane. Everywhere in the Cartesian plane, the functions define the boundaries of regions with regular geometrical patterns. The right triangle and other regular regions are good examples of how the area of a region may be computed using the geometry of the region.

The given function is [tex]\int\limits^{10}_{-10} {|x|} \, dx[/tex].  The function of this integrand is defined as f(x)=|x| with -10 ≤ x ≤ 10. Now, the graph is drawn for this function.

From the graph, we can tell the base and height of the two right-angle triangles are 10 units and 10 units. Then, the area is,

[tex]\begin{aligned}A&=2\left(\frac{1}{2}\times b\times h\right)\\&=2\times \frac{1}{2}\times 10 \times 10\\&=\mathrm{100\;{units}^2}\end{aligned}[/tex]

The area can also be calculated by solving the integrals,

Answer: The y-intercept for part A is 2 and for part B is -5 and the slope for part A is 3 and for part B is 2. ✅

Step-by-step explanation:

PLEASEEEE GIVE BRANLIEST

The y-intercept is a point on the graph where the line of the function crosses the y-axis. It is represented by the number that is next to the y in the equation of a line (y = mx + b).

The slope is the steepness of the line and it is represented by the number that is next to the x (y = mx + b).

In part A, the y-intercept is 2 and the slope is 3. This means that the line starts at the point (0,2) and for every 1 unit on the x-axis, it goes up 3 units on the y-axis.

In part B, the y-intercept is -5 and the slope is 2. This means that the line starts at the point (0,-5) and for every 1 unit on the x-axis, it goes up 2 units on the y-axis.

So the difference between part A and part B is that the y-intercept for part A is 2 and for part B is -5 and the slope for part A is 3 and for part B is 2. This means that the line in part A starts at a different point and is steeper than the line in part B.

Answer:

In the context of a linear function, the y-intercept is the point where the line crosses the y-axis and the slope is the rate at which the line increases or decreases as the x-value increases. If two functions have different y-intercepts, it means that they have different starting points on the y-axis. Similarly, if two functions have different slopes, it means that they have a different rate of change. So, in part A and part B, if the y-intercept and the slope of the function in part A are different from the y-intercept and the slope of the function in part B, it means that the two functions have a different starting point on the y-axis and a different rate of change respectively.

Step-by-step explanation:

In the context of a linear function, a line can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is the point where the line crosses the y-axis. It is represented by the value of b in the equation y = mx + b. For example, if the equation of the line is y = 2x + 3, the y-intercept is (0,3).

The slope of the line is the rate at which the line increases or decreases as the x-value increases. It is represented by the value of m in the equation y = mx + b. For example, if the equation of the line is y = 2x + 3, the slope is 2.

If the y-intercept and the slope of the function in part A are different from the y-intercept and the slope of the function in part B, it means that the two functions have different starting points on the y-axis and a different rate of change respectively.

For example, if the equation of the function in part A is y = 2x + 3, the y-intercept is (0,3) and the slope is 2. And if the equation of the function in part B is y = 4x + 1, the y-intercept is (0,1) and the slope is 4. Therefore, the y-intercept and slope of part A are different from the y-intercept and slope of part B.

Answer: Slope:5/3

Y-intercept: y=1.67x+-4

Step-by-step explanation:

Slope:

Take two points and put it in for m=y2-y1/x2-x1

we can use (0,-4) and (3,1)

m=1--4/3-0

m=5/3

m=1.67

Then we use m in y intercept and use the first point as b

y = mx + b

y=1.67x+b

-4 = 1.67(0) + b

-4 = 0 + b

-4 = b

b = -4

y = 1.67x + -4

Y intercept: y = 1.67x + -4

Slope: 5/3

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

We have LHS = RHS (left hand side = right hand side) in every mathematical equation.

To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.

A statement is not an equation if it has no "equal to" sign.

According to our question-

1. Making use of the two points (20, 80) and (72, 20)

Slope (m) is equal to change in y/change in x, or (80 - 20)/(20 - 72) = 60/-52.

Slope is -1.15 meters.

Change y - b = m to m = -3 and (a, b) = (72, 20). (x - a)

y - 20 = -1.15(x - 72) (x - 72)

y - 20 = -1.15x + 82.8

y = -1.15x + 82.8 + 20

y = -1.15x + 102.8

The best line of fit is the equation y = -1.15x + 102.8.

2. To calculate the monthly heating expense, y, for a month with an average temperature of 35°F (x), enter x = 35 into the formula: y = -1.15x + 102.8.

y = -1.15(35) + 102.8

y = 62.55

Answer:

y - (-2) = -5/3 (x-6)

Step-by-step explanation:

Using Slope Point Formula (y-y1=m(x-x1) we can use the given slope, and the given coordinate to fill in the equation.

So y1 would be -2 because we only have 1 coordinate, and -2 is the y value. So we have y-(-2)=m(x-x1)

Now we have the slope which is m. The slope is -5/3, so we plug that into m. So now we have y-(-2)=-5/2(x-x1).

Last we plug in x1 to the equation which is 6. So to finish the equation we have y-(-2)=-5/3(x-6).

The complete distance in feet on the table are a=6, b=7, c=8, d=7, and e=6.

In mathematics, a revolution is a full rotation, or a full 360-degree turn. The item starts and ends in the same location during a 360-degree revolution.

The circumference of the wheel is equal to the length of a full revolution, or 2*pi*radius. The whole rotation of the wheel is 360 degrees.

The eight of the point is 6 feet, and the wheel's radius is 1 feet.

The point will be in its initial position, which is 6 feet high.

The height will thus be a = 6 + 0 = 6 ft.

The point will reach half the whole height of the wheel, or 2 feet, when the distance travelled is pi/2.

Height of b = 6 + 1 = 7 feet will result.

The point will be at the top of the wheel, which is 2 feet higher than the lower point of the wheel, when the distance travelled equals pi.

The height will thus be c = 6 + 2 = 8 ft.

The point will be half the whole height of the wheel, or 2 feet, when the distance travelled is 3 pi/2.

The height will thus be d = 6 + 1 = 7 ft.

The point will be in its initial position, which is 6 feet high, when the distance travelled is 2 pi.

The height will thus be e = 6 + 0 = 6 ft.

Hence, the complete distance in feet on the table are a=6, b=7, c=8, d=7, and e=6.

60% of what is $54?

We know that of means multiplication and is means equals. This helps us create the equation:

60% x what= $54

Then, we need to make 60% a number we can work with by changing it into a decimal: 0.6. We also need to make 'what' something easier to use as well, so we will use x in place of what:

0.6x=54

Then, get x by itself, which is also called isolating the variable. You do this by dividing by 0.6 on both sides, which is known as using inverse operations.

You should get x=90.

This means that $54 is 60% of $90 and $90 is Noah's goal.

Solving the provided question, we cans say that by quadratic equation, the age where a person's systolic pressure is 127.54 mm Hg is 46

A quadratic equation is x ax2+bx+c=0, which is a quadratic polynomial in a single variable. a 0. The Fundamental Theorem of Algebra ensures that it has at least one solution since this polynomial is of second order. Solutions may be simple or complicated. An equation that is quadratic is a quadratic equation. This indicates that it has at least one word that has to be squared.

systolic pressure for a person of age 45 years, just plug in y = 45:

systolic pressure is 127.54 mm Hg, plug in P = 127.54

P = 0.004y2 - 0.02y + 120

127.54 = 0.004y2 - 0.02y + 120

0 = 0.004y2 - 0.02y - 7.54

Use the quadratic formula to solve this. The quadratic formula (for ay2 + by + c = 0) is:

y = [-b ± √(b2 - 4ac)]/(2a)

In this case a = 0.004, b = - 0.02 and c = - 7.54 so:
