Answer:

O y = 15x + 10 is the only linear function

Hope this helps!!!

Answer:

Yes, the graph of y = -2x^2 + 5 is different from the graph of y = -2x^2. Both equations are quadratic functions with a leading coefficient of -2, which means that they have the same shape of a downward-facing parabola.

However, the graph of y = -2x^2 + 5 is shifted upwards by 5 units compared to the graph of y = -2x^2. This means that for any given value of x, the y-value of y = -2x^2 + 5 will be 5 units higher than the y-value of y = -2x^2.

Answer: 12 inches

Step-by-step explanation:

The 20 inches is the hypotenuse whereas 16 inches is the height of the triangle respectively.

So,

let keep the paper's length as x inches.

20² = 16² + x²

x² = 20² - 16²

x = [tex]\sqrt{20^{2}-16^{2} }[/tex]

x = 12

I am not sure if this is right because i have never done a sum in inches before but  I hope this helps sorry if it is not right.

If repeats are forbidden, the provided letters u, v, w, x, y, and z can be used to create 8 lists of length 3, each of which has a w or u in the second entry.

We can apply the inclusion-exclusion concept to resolve this issue.

First, let's determine how many total lists of length three can be created using the provided letters without any limitations. There are six options for the first submission, five for the second (since it must be either w or u), and four for the third (since no characters can be repeated). Thus, there are a total of the following lists:

6 × 5 × 4 = 120

Next, let's count the number of lists of length 3 that do not have a w or u in the second entry. We have 6 choices for the first entry, 4 choices for the second entry (since we can't choose w or u), and 4 choices for the third entry (since we can't repeat any letters). Thus, the total number of such lists is:

6 × 4 × 4 = 96

Similarly, we can tally the number of lists of length 3 lacking a w or u in the first entry as well as the number of lists of length 3 lacking a w or u in either the first or second entry. Which are:

4 × 5 × 4 = 80 (no w or u in first entry)

4 × 4 × 4 = 64 (no w or u in first or second entry)

Finally, we can use the principle of inclusion-exclusion to count the number of lists that have a w or u in the second entry. This is:

120 - 96 - 80 + 64 = 8

Answer:

angleC = 35°

Step-by-step explanation:

Because AC is the diameter of the circle, angle B = 90°

Then we can use the idea that there are 180° in a triangle to find angle C.

55 + 90 + c = 180

145 + c = 180

c = 35

The measure of angleC = 35°

Option D is incorrect because it gives a value that is not consistent with the scatter plot and the line of fit. The correct answer is: The y-intercept is 40.98. The machine starts with 40.98 ounces of diet soda.

In the context of a graph, the y-intercept is the point where a straight line or curve intersects the y-axis. It is the value of the dependent variable (y) when the independent variable (x) is equal to zero. Mathematically, it is the value of y when x = 0 in the equation of the line or curve. The y-intercept is also known as the initial value or starting point of the graph. It is often denoted as (0, b), where b is the y-coordinate of the intercept point.

The y-intercept of the line of fit represents the starting point of the relationship between the two variables, in this case, the amount of diet soda in the machine and the time after the machine is filled. Therefore, the y-intercept value of 40.98 means that the machine starts with 40.98 ounces of diet soda when it is filled.

Option A is incorrect because the y-intercept is a starting value, and it does not represent a rate of change.

Option B is also incorrect because it suggests that the machine loses 4.8 fluid ounces of diet soda every hour, which is not what the y-intercept represents.

Option D is incorrect because it gives a value that is not consistent with the scatter plot and the line of fit.

Answer:

15.5 feet

Step-by-step explanation:

12 (each foot have 12 inches) × 8 (two 4-foot pieces of rope) = 96

6 (six pieces of rope) × 15 (each rope have fifteen inches long) = 90

90 + 96 = 186

186 ÷ 12 = 15.5

12 × 15.5 = 186

Patty need 15.5 feet.

The numerical value of x rounded to the nearest tenth is 7.5.

The Midsegment Theorem states that the segment joining the midpoints of two sides of a triangle is parallel to and half the length of the third side.

Hence:

the smaller segment = half the third side

From the diagram;

The smaller segment = x

The larger third side = 15

Using the Midsegment Theorem

x = half of 15

Consumer surplus and deadweight loss have decreased due to the price floor of $9.00 set by the government. The correct option is c.

To answer this question, we need to first understand what a price floor is and how it affects the market.

A price floor is a government-imposed minimum price that must be paid for a good or service.

In the context of a market, a price floor that is set above the equilibrium price will create a surplus of the good or service.

This is because the price floor creates a situation where the quantity supplied exceeds the quantity demanded.

Now, let's examine the diagram:

           ^

        | P=$9.00  <- price floor

  S    |  / \

        |  /  \

$10  | /     \

        |/        \

 $8   /           \

$6   /|_________\

        |                      \

        |       Qd   Qs   |

        |___________|

                 Q

In this diagram, the price floor is set at $9.00, which is above the equilibrium price of $8.00.

As a result, there is a surplus of the good, with quantity supplied (Qs) exceeding quantity demanded (Qd).

Now, let's consider the impact on consumer surplus, producer surplus, and deadweight loss:

Consumer surplus is the difference between the price consumers are willing to pay and the actual price they pay. In this case, the price consumers are willing to pay is below the price floor, so consumer surplus is reduced. Therefore, option c.) "Consumer surplus and deadweight loss" is the correct answer.

Producer surplus is the difference between the price producers receive and the minimum price they are willing to accept. In this case, the price producers receive is above the equilibrium price, so producer surplus is increased. Therefore, option b.) "Consumer surplus and producer surplus" is incorrect.

Deadweight loss is the loss of economic efficiency that occurs when the quantity of a good that is bought and sold is below or above the equilibrium quantity. In this case, the price floor creates a surplus, which leads to deadweight loss. Therefore, option d.) "Only deadweight loss" is incorrect.

The solution is A. 3/8. We can calculate it in the following manner.

According to the general equation for conditional probability,

P(A|B) = P(A and B) / P(B)

We are given that P(A|B) = 3/10 and P(B) = 2/5.

We need to find P(A and B) to solve for P(A|B).

Using the formula for conditional probability, we can rearrange the equation as:

P(A and B) = P(A|B) * P(B)

Substituting the given values, we get:

P(A and B) = (3/10) * (2/5) = 6/50 = 3/25

Now, we can find P(A|B) using the first equation:

P(A|B) = P(A and B) / P(B) = (3/25) / (2/5) = (3/25) * (5/2) = 3/10

Answer:

To find out how much more Joi paid than Adelyn for each fidget popper, we need to know how much Adelyn paid for each fidget popper.

If we assume that Adelyn bought the same set of fidget poppers as Joi at the regular price of $20 without tax, then we can calculate how much Adelyn paid for each fidget popper by dividing the total price by the number of fidget poppers in the set.

Let’s say that there are 10 fidget poppers in the set. Then, Adelyn paid $20 / 10 = $2 per fidget popper.

Joi bought the same set of fidget poppers at the regular price of $20 plus 8% sales tax. To find out how much Joi paid for each fidget popper, we can add the sales tax to the regular price and then divide by the number of fidget poppers in the set.

The sales tax is 8% of $20, which is $1.60. So, Joi paid a total of $20 + $1.60 = $21.60 for the set.

If there are 10 fidget poppers in the set, then Joi paid $21.60 / 10 = $2.16 per fidget popper.

To find out how much more Joi paid than Adelyn for each fidget popper, we can subtract Adelyn’s price per fidget popper from Joi’s price per fidget popper:

$2.16 - $2 = $0.16

Therefore, Joi paid $0.16 more than Adelyn for each fidget popper

With little knowledge of the square shape, we know that the area of the shaded region is (B) x² - 2y².

A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles.

It can alternatively be explained as a rectangle with two neighboring sides that are of equal length.

As we previously stated, a square is nothing more than a rectangle with equally long neighboring sides.

The area of a rectangle is therefore expressed as Area = Length Breadth.

So, according to the given figure:
The area of the shaded region would be:

x² - y²

Next, we can use the formula for monthly interest on credit cards, which is:

(balance x monthly interest rate) + (payment - (balance x monthly interest rate)) = new balance

We can solve for the new balance each month, and then use the new balance to calculate the interest for the following month. Here's how it works:

Month 1:

(balance x 0.9992%) + ($350 - (balance x 0.9992%)) = $7,219.17 (new balance)

Month 2:

($7,219.17 x 0.9992%) + ($350 - ($7,219.17 x 0.9992%)) = $6,870.19 (new balance)

Month 3:

($6,870.19 x 0.9992%) + ($350 - ($6,870.19 x 0.9992%)) = $6,516.76 (new balance)

Month 4:

($6,516.76 x 0.9992%) + ($350 - ($6,516.76 x 0.9992%)) = $6,158.68 (new balance)

Month 5:

($6,158.68 x 0.9992%) + ($350 - ($6,158.68 x 0.9992%)) = $5,795.73 (new balance)

Month 6:

($5,795.73 x 0.9992%) + ($350 - ($5,795.73 x 0.9992%)) = $5,427.67 (new balance)

Month 7:

($5,427.67 x 0.9992%) + ($350 - ($5,427.67 x 0.9992%)) = $5,054.24 (new balance)

Month 8:

($5,054.24 x 0.9992%) + ($350 - ($5,054.24 x 0.9992%)) = $4,675.18 (new balance)

Month 9:

($4,675.18 x 0.9992%) + ($350 - ($4,675.18 x 0.9992%)) = $4,290.23 (new balance)

Month 10:

($4,290.23 x 0.9992%) + ($350 - ($4,290.23 x 0.9992%)) = $3,899.12 (new balance)

Month 11:

($3,899.12 x 0.9992%) + ($350 - ($3,899.12 x 0.9992%)) = $3,501.61 (new balance)

At the end of the 11th month, the balance is paid down to $3,501.61, and then at the end of the 12th month, it is paid off completely.

To calculate the total interest paid, we can add up the interest for each month:

$7,568.19 - $7,219.17 = $349.02

$7,219.17 - $6,870.19 = $348.98

$6,870.19 - $6,516.76 = $353.43

$6,516.76 - $6,158.68 = $358.08

$6,158.68 - $5,795.73 = $362.95

After solving (d + 3)(d² - 4d + 1) by using the FOIL method we get d³ - d² - 11d + 3.

The foil method is a strategy for organising your memory of the steps

needed to multiply two binomials. First, outer, inner, and last are the

letters that make up the acronym F-O-I-L.

To solve the given expression using the FOIL method, you have to follow the below steps:

F: Multiply the First terms (d x d²)

O: Multiply the Outer terms (d x -4d)

I: Multiply the Inner terms (3 x d²) and

L: Multiply the Last terms (3 x 1)

Finally, combine the like terms to get the answer

(d + 3)(d² - 4d + 1)= d(d² - 4d + 1) + 3(d² - 4d + 1)

                           = d³ - 4d² + d + 3d² - 12d + 3

Point E: (7, 3), Point F: (1, 3), Point G: (1, -2) and Point H: (7, -2) are the coordinates of each point.

To translate a point in the (x, y) coordinate plane, we add the translation distances to the x-coordinate and the y-coordinate of the point.

For each point in the quadrilateral EFGH, we can apply this translation as follows:

Point E: (4, 5) + (3, -2) = (7, 3)

Point F: (-2, 5) + (3, -2) = (1, 3)

Point G: (-2, 0) + (3, -2) = (1, -2)

Point H: (4, 0) + (3, -2) = (7, -2)

Therefore, after the translation of 3 units right and 2 units down, the coordinates of the points in quadrilateral EFGH are:

Point E: (7, 3)

Point F: (1, 3)

Point G: (1, -2)

Point H: (7, -2)
