How do you know which inequality represents a graph?

Step-by-step explanation:

a linear function is following

y = ax + b

that means the ratio of the y and x differences between the data points is constant (a).

an exponential function is in the form y = a^x. or some constant variations of it.

the base is constant (a), and the exponent of the constant is the variable (x).

1.

clearly exponential.

this is the typical graph of an exponential function.

it looks like y = 2^x, as e.g. f(4) = 2⁴ = 16, and the graph seems to be at least very close to this.

2.

exponential.

y = 3^(x - 0.5)

3¹ = 3

3² = 9

3³ = 27

3⁵ = 243

this is just y = 3^x shifted to the right by 0.5 units.

3.

linear.

the difference ratio between the data points is constant :

x is the row number (1, 2, 3, 4, 5, ...).

y is the number of seats per row (14, 16, 18, 20, 22, ...).

so,

(16-14)/(2-1) = 2/1 = 2

(18-16)/(3-2) = 2/1 = 2

...

(22-14)/(5-1) = 8/4 = 2

always constant (2).

4.

neither.

it is y = x²

when you compare 4. and 1. you see the clear difference between the 2 graphs.

5.

exponential.

remember, y = a^x.

well, here, a = 1/2. but that is still constant and doesnot change the principle.

the factor 10 stretches the graph a bit up (in fact, this 10 is the starting number of an exponential growth). but the function in its core is still exponential.

6.

linear.

when written that way, it just means that x = n, and for every increase of n by 1, y (f(n)) increases by +4.

so, the difference ratio stays constant (4/1 = 4).

The function increases on [0,∞] and decreases on [-∞,0]. The absolute minimum value of f is 0, and its relative minimum value is the same (0,0).

When x<  0, you can see on the graph that there is a "open circle" at (0, 0).

Thus, due to the graph's indefinitely high y values, there is likewise no absolute maximum value for f.

The midpoint of the x-intercepts of f(x) = (x - 4)(x + 4) is (0, 0).

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

A compass and straightedge setup can be used to locate the midpoint of the line segment they determine given two points of interest. By initially building a lens out of circular arcs with equal radii centered at the two endpoints and joining the cusps of the lens, one can determine the midpoint of a line segment immersed in a plane. The midpoint of the segment is then the place where the line joining the cusps intersects the segment.

The inverse of the given function is y = -1/5(x + 1).

The graph the function and its inverse is shown in the image attached below.

In Mathematics, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

In order to determine the inverse of this function f(x) = -1 - 1/5x, we would interchange both the input value (x) and output value (y) as follows:

y = -1 - 1/5x

x = -1 - 1/5y

Adding 1 to both sides of the function, we have:

x + 1 = -1/5y

Multiplying both sides of the function by -1/5, we have:

y = -1/5(x + 1)

solving for "xx"

When Olivia tries to cut a piece of metal 45 inches long, the piece of metal ends up being 43.5 inches long, then there is an approximate percent error of 3.33%  in this situation.

Therefore the answer is 3.33%.

To calculate the approximate percent error in this situation, we can use the formula:

Percent Error = (|Experimental Value - Theoretical Value| / Theoretical Value) x 100

In this case, the experimental value is 43.5 inches and the theoretical value is 45 inches. Plugging these values into the formula, we get:

Percent Error = (|43.5 - 45| / 45) x 100

= (1.5 / 45) x 100

= 0.033 x 100

= 3.33%

So the approximate percent error in this situation is 3.33%.

The manager should expect the defective nails of 350-pound delivery to contain 23.3 pounds .

The defect rate is a measurement of the proportion of production units that are flawed or useless relative to a certain number of units. Businesses use this assessment to assess the quality of their products and how they affect their bottom line. Although lower rates are desired, no industry has a set acceptable fault rate. Therefore, businesses must choose their goal defect rate.

Defect rate is crucial because it enables firms to calculate the proportion of output units that fail quality checks. This assists the firms in identifying any issues with quality control or manufacturing and estimating the cost of each fault. To estimate the profitability of a product, businesses can also compare failure rates among comparable or dissimilar products.

In ever 4.5 pounds of nail defective nails are = 0.3 pounds

In ever 1 pounds of nail defective nails are = 0.3/4.5 pounds

The sine of an acute angle in a right triangle is the ratio of the angle of the triangle to the opposite side of the hypotenuse.

Trigonometric ratios:

Trigonometric ratios are the ratios of the lengths of the sides of a triangle. These ratios in trigonometry relate the aspect ratio of a right triangle to each angle. A basic trigonometric ratio is the ratio of sin, cos, and tan, or the ratio of sin, cos, and tangent. Other important trigonometric ratios cosec, sec, and cot can be derived from sin, cos, and tan, respectively.

Acute Sine Ratio:

The tangent function examines the ratio of his two legs of a right triangle. You can also use the ratio of leg length divided by hypotenuse length.

In a right triangle, each angle has an opposite side and an adjacent side. And there is always a hypotenuse. On the opposite side and the hypotenuse we are dealing with the sine ratio. The sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse. In a right triangle, the sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse.

Let's examine some properties of the sine ratio using the Pythagorean theorem. For a right triangle, let the lengths of the triangle be a, b, and c. where a is the length of the other side of A and b is the length of the other side of B.

Your score without the penalty is 9.424.

To find your score without the penalty, we need to add 0.3 points back to your final score of 9.124. We can use the linear equation:

x = 9.124 + 0.3

This equation represents the original score, represented by x, plus the penalty of 0.3. To solve for x, we need to add 0.3 to 9.124:

x = 9.124 + 0.3

x = 9.424

So your score without the penalty is 9.424.

In this equation, x is being used to represent the original score, before the 0.3-point penalty was applied. The equation x = 9.124 + 0.3 represents that the original score was 9.124 and 0.3 points were taken off due to stepping out of bounds. By solving the equation, we are able to find the original score without the penalty which is 9.424

To find the percentage increase of the slave population from 1800 to 1860, we can use the following formula:

What does math's % mean?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

percentage increase = (new value - original value) / original value x 100

We know that in 1800 the slave population was 893,602 and in 1860 the slave population was 1,953,760. So we can plug in these values into the formula:

percentage increase = (1,953,760 - 893,602) / 893,602 x 100

percentage increase = (1,060,158) / 893,602 x 100

percentage increase = 1.1885 x 100

percentage increase = 118.85

To find the amount of money that remains per person after buying raisins, we first need to find the total cost of the raisins. If 4 boxes of raisins cost $1.50 each, then 4*1.50 = $6 is spent on raisins.

To find the amount of money that remains for popcorn and drinks, we subtract the cost of the raisins from the total amount of money: 25-6 = $19.

Since there are 5 people in total (you and 4 friends), we divide the remaining money by 5 to find the amount per person: 19/5 = $3.80 per person.

The cost of a gold ticket is x + 8.

We know that Patrick spent 10x + 10(x+8) = $140
