The polynomial function that best fits the graph is f(x) = 130(x+3)(x-2)²(x-5).

The given graph exhibits three x-intercepts at x = -3, 2, and 5, and the y-intercept is positioned at (0, 2). The graph passes through the x-axis linearly at x = -3 and x = 5, indicating that the corresponding factors of the polynomial will be linear. However, at x = 2, the graph bounces off the x-axis at the intercept, implying that the corresponding factor of the polynomial will be quadratic. Therefore, the polynomial function can be expressed as follows:

f(x) = a(x+3)(x-2)²(x-5)

To find the stretch factor 'a,' we can use another point on the graph, such as the y-intercept (0, 2). By plugging in the values, we obtain:

f(0) = a(0+3)(0-2)²(0-5)

-2 = a(0+3)(0-2)²(0-5)

-2 = -60a

Step-by-step explanation:

Te advertiser's cost per viewer for a 30-second ad is $0.01025.

Cost per view means an ads model that charges the advertiser whenever a user watches an ad for a set duration.

To calculate the cost per viewer for the advert, we need to divide the advertising fee by the number of viewers which gives us:

Cost per viewer = Advertising fee / Number of viewers

Substituting the values, we get:

= $165,000 / 16.1 million viewers

= $165,000 / 16,100,000 viewers

= 0.0102484472 per viewer

= $0.01025 per viewer.

The 7.34 cubic yards of concrete needed to pour the foundation walls, which is calculate the volume of the walls and then add the waste factor of 6%.

To find the volume of the concrete needed to pour the foundation walls, we first need to find the total area of the walls. We can do this by breaking it down into three sections

The two 26 ft x 1 ft walls

Area = 2 x (26 ft x 1 ft) = 52 sq ft

The two 42 ft x 1 ft walls

Area = 2 x (42 ft x 1 ft) = 84 sq ft

The 12 in x 15 in x 12 ft wall

First, we need to convert the dimensions to feet:

Length = 12 in ÷ 12 = 1 ft

Breadth = 15 in ÷ 12 = 1.25 ft

Height = 12 ft

Area = (1 ft + 1.25 ft) x 2 x 12 ft = 51 ft²

Total area of the walls = 52 sq ft + 84 sq ft + 51 sq ft = 187 sq ft

Now, we need to add the waste factor of 6% to this to account for any material that may be lost or wasted during the pouring process

Total area with waste factor = 187 sq ft + 6% of 187 sq ft = 198.22 sq ft

Finally, we need to calculate the volume of concrete needed, assuming a thickness of 1 ft

Volume = area x thickness = 198.22 sq ft x 1 ft = 198.22 cubic ft

Since 1 cubic yard is equal to 27 cubic feet, we can convert the volume to cubic yards

Volume in cubic yards = 198.22 cubic ft ÷ 27 = 7.34 cubic yards

Therefore, we need 7.34 cubic yards of concrete to pour the foundation walls with a 6% waste factor.

Answer: y = -4x + 1. Brainliest?

Step-by-step explanation:

To write a function rule that has a greater rate of change than the given function, we need to find the slope of the given function. We can use the two points (-2, 7) and (2, -5) from the table to calculate the slope as:

slope = (change in y) / (change in x) = (-5 - 7) / (2 - (-2)) = -3

So the slope of the given function is -3. To create a new function rule with a greater rate of change, we can choose a larger slope. Let's choose a slope of -4. We also need to find the y-intercept (b) of the new function, which we can do by plugging in one of the points from the table and solving for b. Let's use the point (0, 1):

y = mx + b

1 = (-4)(0) + b

b = 1

So the function rule with a greater rate of change and passing through the point (0, 1) is:

y = -4x + 1

The equivalent speed in still water to achieve the actual speed is 27.172 km/h

Given data ,

The boat's velocity vector in still water will have two components: one along the north direction (opposite to the current) with magnitude "v" km/h, and one along the northwest direction (due to the current) with magnitude 4 km/h.

Since the boat is moving in a direction that is 45 degrees between north and northwest, we can use trigonometry to find the component of velocity in the northwest direction. By using the cosine of 45 degrees, we get:

Component of velocity in northwest direction = 4 km/h x cos(45 degrees) = 4 km/h x 0.707 = 2.828 km/h

Now , adding the components of velocity in the north and northwest directions should result in a speed of 30 km/h, which is the real speed needed to go through still water.

v + 2.828 = 30

v = 27.172 km/h

Hence , the equivalent speed of the boat in still water to achieve an actual speed of 30 km/h is approximately 27.172 km/h

Step-by-step explanation:

We can work percentage problems using the formula

P%x = y, where P is the percentage, x is the "of" value in the problem, and y is the "is" value in the problem.

Thus, in the formula, our p value is 0.30, our x ("of") value is 26.5 and we're trying to find our y ("is") value:

0.30 * 26.5 = y

7.95 = y

Considering the given graph,  we infer that while rolling a dice is random, the median values do exhibit some patterns that can be analyzed and used to make predictions about the expected values.

Looking at the median data from the graph, we can infer that option A is not true, as the median appears to be equally likely to fall between any two numbers from 1 to 6. However, we can also infer that option B is not entirely accurate.

While it is true that rolling a dice is random and each roll is independent, we can observe patterns in the median data.

For example, the median values are more likely to be closer to 3.5, which is the theoretical median value of a fair six-sided dice. This suggests that the more times the dice is rolled, the more likely the median value will approach the expected value.

We can also observe that the spread of the median values tends to decrease as the number of rolls increases, indicating that more rolls lead to more consistent results.

The percent of time that customers at the old store bought milkshakes: 20%.

The percent of time that customers at the new store bought milkshakes: 26%.

The percent of total sales that were Ice Cream sales in both shops: 78%.

The percent of new store sales out of the total sales for both shops: 35%.

First of all, we would have to determine the total number of sales for both the Old store with respect to the number of servings of ice cream and milk shakes that were sold;

Total sales = 52,100 + 13,400

Total sales = 65,500

Next, we would determine the percent of time that customers at the old store bought milk shakes;

Percent = 13,400/65,500 × 100

Percent = 20.46 ≈ 20%.

Similarly, we would determine the percent of time that customers at the new store bought milk shakes;

Total sales = 25,800 + 9,200

Total sales = 35,000

Percent = 9,200/35,000 × 100

Percent = 26.29 ≈ 26%.

Total sales in both stores = 52,100 + 13,400 + 25,800 + 9,200

Total sales in both stores = 100,500

Percent of ice cream in both stores = (52,100 + 25,800)/100,500 × 100

The difference between the actual mean time taken to complete the quiz and the time Sam says is -0.2 minutes.

The mean, also known as the average, is a measure of central tendency that represents the sum of all values in a data set divided by the number of data points.

Mathematically, the mean is defined as:

Mean = (Sum of all values) / (Number of data points)

According to the given information:

To find the difference between the actual mean time taken to complete the quiz and the time Sam says, we can follow these steps:

Find the actual mean time taken to complete the quiz:

Add up all the given times: 13 + 16 + 8 + 9 + 12 + 14 + 20 + 36 + 11 + 5 + 13 + 16 + 8 + 9 + 12 + 14 + 20 + 36 + 11 + 5 = 236

Divide the sum by the number of data points (20, since there are 20 quiz times): 236 / 20 = 11.8 minutes

Calculate the difference between the actual mean time and the time Sam says:

Actual mean time taken to complete the quiz: 11.8 minutes

Time Sam says: 12 minutes

Answer:

It will take approximately 6.89 years for the investment to grow to $9737.

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment

P = the present value of the investment

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

We know that P = $7000, r = 0.034, n = 4 (since the interest is compounded quarterly), and we want to find t when A = $9737.

$9737 = $7000(1 + 0.034/4)^(4t)

Divide both sides by $7000:

1.391 = (1 + 0.034/4)^(4t)

Take the natural logarithm of both sides:

ln(1.391) = ln[(1 + 0.034/4)^(4t)]

Use the power rule of logarithms:

ln(1.391) = 4t * ln(1 + 0.034/4)

Divide both sides by 4 ln(1 + 0.034/4):

t = ln(1.391) / [4 * ln(1 + 0.034/4)]

Using a calculator, we find:

t ≈ 6.89 years

Therefore, it will take approximately 6.89 years for the investment to grow to $9737.

The height of the pole is 18.18 feet

Given data ,

Elka uses similar triangles to find the height of the pole. The situation forms two similar right triangles: one with the pole and the mirror, and another with Elka's eyes and the mirror.

Let's denote the height of the pole as "h" feet.

Distance from the base of the pole to the mirror = 20 feet

Distance Elka moves back away from the mirror = 5.5 feet

Height of Elka's eyes above the ground = 5 feet

Using the concept of similar triangles, we can set up the following proportion:

h / 20 = 5 / 5.5

Multiply by 20 on both sides , we get

h = 100 / 5.5

h = 18.18 feet

Hence , the height of the flagpole is approximately 18.18 feet

what is system of equations?

A system of equations is a set of two or more equations with the same variables. The solution to a system of equations is a set of values for the variables that satisfy all the equations in the system simultaneously.

For example, consider the following system of two equations:

x + y = 5

2x - y = 3

This is a system of two equations with two variables, x and y. The solution to this system is the values of x and y that make both equations true at the same time. In this case, the solution is x = 2 and y = 3, because when we substitute these values into the equations.

In base twelve, the place values increase by a factor of twelve at each position, starting from the rightmost position. The rightmost position has a place value of 1, the next position to the left has a place value of 12, the next position to the left has a place value of 12^2 = 144, and so on.

To convert the number 1t5e in base twelve to base ten, we need to multiply each digit by its corresponding place value, and then add up the results:

1t5e (base twelve) = 1 * 12^3 + 10 * 12^2 + 5 * 12^1 + 11 * 12^0

= 1 * 1728 + 10 * 144 + 5 * 12 + 11 * 1

= 1728 + 1440 + 60 + 11

= 3239

Therefore, 1t5e twelve represents the number 3239 in base ten.
