Pls hurry. Find the approximate area of a circle with a diameter of 16 units.

Answer = units squared

The point that appears to be closest to the coordinates (29, 37.7) on the scatter plot is (29,37).

A scatter plot is a type of chart that displays values for two variables for a set of data. The data points in a scatter plot are represented by dots or circles, and their position on the chart represents the values of the two variables. One variable is usually plotted on the horizontal axis (x-axis) and the other variable is plotted on the vertical axis (y-axis). By analyzing the pattern of the scatter plot, you can see whether there is a relationship between the two variables, and what kind of relationship it is (positive, negative, or no relationship). Scatter plots are useful for identifying patterns, trends, and relationships in data, and are commonly used in scientific research, engineering, economics, and many other fields.

Here,

To find the foot length closest to 29, we need to look for the point on the scatter plot that has an x-value closest to 29.

Using the equation of the line provided (y=0.3x+29), we can see that when x=29, y=0.3(29)+29=37.7. Therefore, we are looking for the point on the scatter plot with an x-value close to 29 and a y-value close to 37.7.

Answer: $0.85 per tomato

Step-by-step explanation:

To find the unit rate, we need to determine the cost of one tomato. We can do this by dividing the total cost of the four tomatoes by the number of tomatoes:

$3.40 ÷ 4 = $0.85

Therefore, the cost of one tomato is $0.85. The unit rate can also be expressed as a fraction, which is:

$0.85 per tomato, or 85 cents per tomato

Answer:

The Unit rate is 0.85

Step-by-step explanation:

You divide it by 4

Answer: y=3x

Step-by-step explanation: To find the equation of the line m, which is the image of line t after a dilation with a scale factor of 1/2 centered at the origin, we need to follow these steps:

Rewrite the equation of line t in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

3X - Y = 6

-Y = -3X + 6

Y = 3X - 6

So the slope of line t is 3.

Apply the dilation with a scale factor of 1/2 centered at the origin. This means that every point on line t is multiplied by 1/2 in both the x and y directions. The origin (0,0) remains fixed.

The new coordinates of any point on line t after dilation are given by (1/2x, 1/2y).

Use the new coordinates to find the equation of line m. To do this, we need to find the slope of line m and a point on it.

The slope of line m is the same as the slope of line t, which is 3.

To find a point on line m, we can use the fact that the origin remains fixed after dilation. So the point (0,0) is on line m.

Using the slope-intercept form, y = mx + b, we can write the equation of line m as:

y = 3x + b

To find the value of b, we can use the point (0,0):

0 = 3(0) + b

b = 0

Therefore, the equation of line m is y = 3x.

The Equation of line m is y= 3x - 3.

A scale factor is a number that can be used to adjust the size of any geometrical figure or object in relation to its original size. It's used to draw the enlarged or reduced shape of any given figure, as well as to calculate the missing length, area, or volume of an enlarged or reduced figure. It should be noted that the scale factor only affects the figure's size and not its shape.

We have, Equation of line t

3x - y = 6

Take x= 0 then y = -6 and y= 0 then x = 2.

Now, dilate the coordinates by factor 1/2 as

(0, -3) and (1, 0).

So, the Equation of line m is

(x - 0) / (1- 0) = (y - (-3)) / (0 - (-3))

x/1 = y + 3 / 3

3x = y+ 3

y= 3x - 3

Triangle ABC can be mapped onto triangle XYZ by a composition of transformations represented by (x,y) → (x+3,y-6) and followed by a dilation with center (0,0) and scale factor 1/3 represented by (x,y) → (x/3,y/3).

Dilation is a geometric transformation that involves changing the size of an object while maintaining its shape and proportions. In dilation, every point of the original figure is expanded or contracted away from a fixed point called the center of dilation.

The ratio of the distance between the center of dilation and each point of the original figure is the same for all corresponding points in the dilated figure. This ratio is called the scale factor, and it determines the degree of dilation.

If the scale factor is greater than 1, the figure is enlarged or dilated, while if the scale factor is less than 1, the figure is reduced or contracted. If the scale factor is negative, the figure is reflected across the center of dilation before being dilated.

Triangle ABC can be mapped onto triangle XYZ by a composition of transformations represented by (x,y) → (x+3,y-6) and followed by a dilation with center (0,0) and scale factor 1/3 represented by (x,y) → (x/3,y/3).

The value of the principal investment (rounded to the nearest hundredth) is $9,000.39.

Interest rate refers to the percentage amount charged or paid on a loan or investment, usually expressed as an annual percentage rate (APR). It represents the cost of borrowing or the return earned on an investment.

The equation you provided represents the compound interest formula:

A = P[tex](1 + r/n)^(n*t)[/tex]

Given that the annual interest rate is 6% and is compounded quarterly (i.e., n = 4), and the amount in the account after 15 years is $16,497.06, These values can be plugged into the equation to find P.

A = $16,497.06

r = 0.06 (6% expressed as a decimal)

n = 4

The vertex of the parabola is at (1, -9). The x-intercepts are (-2, 0) and (4, 0), which are the points where the parabola crosses the x-axis. The y-intercept is (0, -8), which is the point where the parabola crosses the y-axis.

What is vertex ?

To find the vertex and the x- and y-intercepts of the equation y = x² - 2x - 8, we can start by completing the square to put the equation in vertex form:

y = x² - 2x - 8

y + 8 = x² - 2x

y + 8 + 1 = x² - 2x + 1

y + 9 = (x - 1)²

So, the vertex of the parabola is at (1, -9). The x-coordinate of the vertex is found by taking the opposite of the coefficient of x in the equation (which is -2) and dividing by two times the coefficient of x (which is 1), giving x = -(-2) / (2*1) = 1. The y-coordinate is found by substituting x = 1 into the equation.

What are the intercepts?

To find the x-intercepts, we set y = 0 and solve for x:

0 = x² - 2x - 8

0 = (x - 4)(x + 2)

So, the x-intercepts are at (-2, 0) and (4, 0).

To find the y-intercept, we set x = 0 and solve for y:

y = 0² - 2(0) - 8

y = -8

So, the y-intercept is at (0, -8).

To graph the parabola, we can use the vertex and intercepts we found.

The vertex is (1, -9), which is the lowest point on the parabola. The x-intercepts are (-2, 0) and (4, 0), which are the points where the parabola crosses the x-axis. The y-intercept is (0, -8), which is the point where the parabola crosses the y-axis.

Bus 14 is therefore the more reliable bus as a result of its lower IQR.

The dot plot, which depicts the frequency with which each observation appears in the data set, is the first thing we take into account.

The difference between the data set's third and first quartiles is represented by the interquartile range, which is the next factor we take into account.

Because it ignores outliers, the interquartile range is a better indicator of a spread than a data set's range.

We have the following for classes of 15 students:

Since the first seven students make up the first half, the first quartile is represented by the fourth dot, which represents the first half's median.

The final seven students make up the second half, thus the eleventh dot—the first half's median—is in the first quartile.

So, the following are the Bus 14 quartiles:

Q1 = 12.

Q3 = 18.

The IQR is therefore of:

IQR = Q3 - Q1 = 18 - 12 = 6.

Hence, the IQR is:

Q1 = 9.

Q3 = 16.

The IQR is therefore of:

IQR = Q3 - Q1 = 16 - 9 = 7.

Therefore, bus 14 is therefore the more reliable bus as a result of its lower IQR.

To find the upper and lower bounds of c - d, we first need to find the maximum and minimum possible values of c and d.

For c rounded to 1 decimal place, the actual value of c could be between 47.25 and 47.34.

This is because when we round to 1 decimal place, we take the first decimal place and round up or down depending on the second decimal place.

Similarly, we have

To calculate the monthly payment for the TV after the discount, sales tax, and financing, we need to follow these steps:

Step 1: Calculate the discount

Discount = 25% of $987.48

Discount = 0.25 x $987.48

Discount = $246.87

Step 2: Calculate the discounted price of the TV

Price after discount = $987.48 - $246.87

Price after discount = $740.61

Step 3: Calculate the sales tax

Sales Tax = 6.5% of $740.61

Sales Tax = 0.065 x $740.61

Sales Tax = $48.15

Step 4: Calculate the total cost of the TV after discount and sales tax

Total cost = Price after discount + Sales Tax

Total cost = $740.61 + $48.15

Total cost = $788.76

Step 5: Calculate the monthly payment on the 2-year loan with 15.6% annual interest rate using the following formula:

Monthly Payment = (P x r) / (1 - (1 + r)^(-n))

where P is the principal (total cost of the TV), r is the monthly interest rate (15.6% / 12), and n is the number of months (24).

Monthly Interest Rate = 15.6% / 12

Monthly Interest Rate = 0.013

Monthly Payment = ($788.76 x 0.013) / (1 - (1 + 0.013)^(-24))

Monthly Payment = $36.89

Therefore, the monthly payment on the 2-year loan for the TV is $36.89.

An equation is a mathematical statement that asserts the equality of two expressions. It typically contains one or more variables, which represent unknown values that can be solved for using algebraic methods. An equation can be represented symbolically using mathematical notation, such as using letters, numbers, and mathematical symbols like +, -, x, /, and =. Equations can be used to model and solve a wide variety of problems in mathematics, science, engineering, and other fields.

Here,

We can start by finding the linear equation that relates price and monthly sales. Let's use the point-slope form of a linear equation:

y - y1 = m(x - x1)

where y is the monthly sales, x is the price, m is the slope, and (x1, y1) is a point on the line.

Using the two points we have:

(10, 19000) and (7, 25000)

We can find the slope:

m = (y2 - y1) / (x2 - x1)

m = (25000 - 19000) / (7 - 10)

m = 2000

Now we have:

y - 19000 = 2000(x - 10)

Simplifying:

y = 2000x - 11000

This equation represents the relationship between price and monthly sales.

To maximize revenue, we need to find the price that gives the highest value for the product of price and monthly sales. In other words, we need to find the maximum value of the function:

R(x) = x * y = x(2000x - 11000)

Expanding and simplifying:

R(x) = 2000x² - 11000x

To find the maximum, we need to take the derivative and set it equal to zero:

R'(x) = 4000x - 11000 = 0

Depending on their size, multiple shapes may have the same circumference. For example, imagine a triangle made up of wires of length L.

The same wire can be used to create a square if all sides are the same length.

The length covered by the perimeter of the shape is called the perimeter. Therefore, the units of circumference are the same as the units of length.

As we can say, the surroundings are one-dimensinal. As a result, you can measure in meters, kilometers, millimeters, etc.

Inches, feet, yards, and miles are other globally recognized units of circumference measurement.

According to our question-

cos(90∘−θ)=sinθ

sin(90∘−θ)=cosθ

cos²∅+sin²∅= 1.
