If r=1 and 0=pi/4, what is the approximate arc length?

Answer:

p = 6.95 + (0.95 × t)

Step-by-step explanation:

A function rule explains how to convert an input value (x) into an output value (y) for any given function.

To get the total price (p) we need to add the cost of the pizza itself, and add each topping. The part of the equation (0.95 × t) can solve for the price of each topping, so we add that on.

In 120 minutes, all the three boats will next meet at the starting location. The solution has been obtained by using the concept of least common multiple.

What is least common multiple?

Least Common Multiple is abbreviated as LCM. The smallest multiple shared by two or more different numbers is referred to as the least common multiple.

We are given that three boats start cruising around a small island starting at the same time and from the same location, and following the same route.

They take one full circle around the island which is 2 km.

First boat:

It covers 5 km in 60 minutes.

So, it will cover 2 km in 60/5 * 2 = 24 minutes

Second boat:

It covers 4 km in 60 minutes.

So, it will cover 2 km in 60/4 * 2 = 30 minutes

Third boat:

It covers 3 km in 60 minutes.

So, it will cover 2 km in 60/3 * 2 = 40 minutes

Now, taking the LCM of 24, 30 and 40, we get 120.

Hence, in 120 minutes all the three boats will next meet at the starting location.

Answer: Decay

Step-by-step explanation:

The value of f(-7) in the given function, f(x) = -x^2 + 2x + 6, is -57

From the question, we are to determine the value of f(-7) in the given function

The given function is

f(x) = -x^2 + 2x + 6

To find the value of f(-7) in the given function,

We will substitute -7 for x in the expression for f(x) and evaluate the resulting expression

That is,

f(x) = -x^2 + 2x + 6

f(-7) = -(-7)^2 + 2(-7) + 6

Simplifying this expression gives:

f(-7) = -49 - 14 + 6

f(-7)= -57

Hence, the value of f(-7) is -57

The average cost of an entree on a restaurant menu that is $15 describes the mean, not the median.

The mean is the average value of a data set.

To compute the average, the total value of the data set is divided by the number of items involved.

The average value or mean is the quotient of the total value and the number of data items.

On the other hand, the median describes the middle value of an ordered list of data values.

The product of (3 x 107) and (2 x 107) is 6.8694 x 10^4

To find the product of (3 x 107)and (2 x 107), we can use the distributive property of multiplication which states that the product of a number and a sum is equal to the sum of the products of the number and each term in the sum. In this case, we can multiply the numbers outside the parentheses first, and then multiply the result by the common factor of 107 to simplify the expression:

(3 x 107) x (2 x 107) = 6 x (107 x 107)

Next, we can calculate the product of 107 and 107, which is 11,449:

Answer: Use the Pythagoream theorem: a²+ b² = c²

Step-by-step explanation: note that c = the hypotenuse

2² + 5² = c²

Simplify

4 + 25 = c^2

Combine like terms

29 = c^2

isolate the c. Root both sides

√29 = c

c = 5.38516481

5.39 is your answer

The shortest distance is 5.39 miles  between your home and the mall

The length along a line or line segment between two points on the line or line segment.

Distance=√(x₂-x₁)²+(y₂-y₁)²

The distance from your home to the school is 2 miles south, which means the y-coordinate of the school is -2.

The mall is located 5 miles west of the school, which means the x-coordinate of the mall is -5.

So, we have two points on the coordinate plane: your home at (0, 0) and the mall at (-5, -2).

The distance between them can be found using the distance formula:

Distance=√(x₂-x₁)²+(y₂-y₁)²

=Distance=√(-5-0)²+(-2-0)²

=√25+4

The quotient of (5+21) (6-4) and (2+1) is 13/3, expressed in its simplest form

The quotient of two numbers is a way of expressing the ratio of their values. It is the result of dividing one number by the other, and can be written as a fraction or as a decimal.

The quotient of 4 and 8 is 0.5, since 4 divided by 8 is 0.5.

The quotient of (5+21) (6-4) and (2+1) can be expressed as follows:

First, we need to solve each parenthesis separately. The first parenthesis is (5+21), which equals 26. The second parenthesis is (6-4), which equals 2. Therefore, the quotient of (5+21) (6-4) is 26/2, which can be simplified to 13/1.

Step-by-step explanation:

The weighted average ROR of the investments, based on the provided investment portfolio, would be 2.1%.

By multiplying each data point by its weight and adding the resulting products, the weighted average is calculated. The weights for all the data points are then added. Divide the weight*value products by the total weights to finish. You've successfully determined the weighted mean.

Find the overall portfolio value first:

= 2,600 + 3,700 + 575 + 1,225

= $8,100

The investments' weighted average Rate of Return (ROR) is:

= (2,600 / 8,100 x 1.7%) + (3,700 / 8,100 x 3.2%) + (575 / 8,100 x 12.9%) + (1,225 / 8,100 x -5.6%)

The entire area a cylinder occupies in three dimensions is known as the cylinder's area. The combined areas of the two circular bases and the curving surface make up the cylinder's surface area. In right cylinders, the axis line creates a right angle to the base, and the two circular bases are perfectly over one another. It is referred to as an oblique cylinder if one of the circular bases is misaligned and the axis does not make a right angle with the base.

The curving surface that sits in the center of the two circular bases opens to reveal a rectangular shape. A lateral surface is another name for this curved surface.

The total surface area of the cylinder is given by the formula:

TSA = 2πr(r + h)

We can graph the data in a line graph to visualize the relationship between the two variables. The graph will have time (t) represented on the x-axis and the balance of the savings account (m) represented on the y-axis. The graph will demonstrate that the total balance of the two accounts increases over time.

The equation that models this data can be found by using the slope-intercept form, y = mx + b. Here, y represents the balance of the savings account (m), x represents the time (t), m is the slope of the line, and b is the y-intercept. To find the equation, we can first find the slope, which is the change in y divided by the change in x. This is (2,800 - 500) / (3 - 0) = 2,300 / 3 = 766.67. The y-intercept is the balance of the savings account when t = 0, which is 500. We can now write the equation as m = 766.67x + 500.

The conversion of 184 centimetres in feet is equals to the 6.03 feet. Thus, conversion factor from centimetres to feet is 6.03/184 = 0.032.

A conversion factor is a number used to convert one set of units into another set of units by multiplication or division. If conversion is necessary, a conversion factor suitable for equivalent value must be used. For example, to convert meters to centimetres, the appropriate conversion value is 100 centimetres equal 1 meter. It includes converting a value from inches to millimeters, for distance from miles to kilometers, feet or other units. How to convert centimeters to feet : One meter is a measure of length and equals approximately 3.28 feet. Thus conversion factor is 3.28 feet. So, 184meters

= 184× 3.28 feet

= 603.52 feet --(1)

But we need to convert 184 centimeters to feet. So, change meters to centimeters. As you know, 1 meter = 100 centimeters, so 184 meters = 18400 centimeters --(2). Now from equations (1) and (2),

18400 centimeters = 603.52 feet,
