To convert percentages to decimals, simply divide the percentage by 100. Or move the percentage sign two places to the left and change it to a decimal point.

So the answer is 0.32

The area of the shape is 12.56 square units

From the question, we have the following parameters that can be used in our computation:

Radius = 2

The area of a circle is calculated as

Area = pi * r^2

Substitute the known values in the above equation, so, we have the following representation

Area = 3.14 * 2^2

Evaluate

Area = 12,56

Hence, the area is 12.56 square units

The area of the rectangle shaped floor is 1820 square yard and other values are given below.

What is a rectangle?

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square.

For example, if one side of a rectangle is 20 cm, then the side opposite to it is also 20 cm.

A rectangle has two diagonals, that bisects each other. Both the diagonals are equal in length.

Perimeter, P = 2 (Length + Width)

Area of Rectangle=Length*Breadth

Step-by-step explanation:

By 17.77 percent this stock price rises.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, In one day, the stock price for Warbeck's Coffee rose from $5 to $6 per share.

From the general formula of percentage:

Percentage = difference value/ total value * 100

In our case,

Difference value = 6-5

Difference value = 1

total value = 6

thus,

Percentage change = 1/6 * 100

percentage change = 17.77%
Therefore, By 17.77 percent this stock price rises.

The 25th percentile of radiation levels is given as follows:

P25 = 0.905 W/kg.

A measure is said to be in the xth percentile of the data-set if it the bottom separator of the bottom x% of measures of the data-set and the top (100 - x)% of measures, that is, it is greater than x% of the measures of the data-set.

In this problem, the data-set has 50 elements, hence the position of the element at the 25th percentile is given as follows:

0.25 x 50 = 50/4 = 12.5.

Meaning that the 25th percentile is the mean of the 12th and 13th elements, as follows:

P25 = (0.9 + 0.91)/2

P25 = 0.905 W/kg.

The power function, h(x) = [tex]$$3x^{0.5[/tex] then the domain for h(x) is [0, ∞).

A power function is a single-term function that has a real number, a coefficient, and a variable raised to a specified real number as its product. Coefficients are numbers that multiply a variable by itself when it is increased to an exponent.

A variable base raised to a fixed power is a component of a power function. This function is raised to a variable power from a constant base. Not a power function, but an exponential function is what this is.

The power function in statistics is a function that connects the likelihood of rejecting a null hypothesis on the value of a parameter to its true value. An exponential function has its variable in its exponent, whereas a power function has its variable in its base. This is the key distinction.

The value of s(x) depends on the value of x since s is a function of x.

What is a function?

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Here,

We know that for any function f(x) ; x represents the independent variable i.e. the variable whose value is defined and y=f(x) denotes the dependent variable i.e. the variable whose value is defined corresponding to the independent variable.

i.e. it depends on the variable x.

Similarly here s(x) is the dependent variable since it is defined corresponding to the variable x.

Hence, The value of s(x) depends on the value of x, since s is a function of x.

When 75°30' converted into radian it will be 1.309 radians.

A radian is a unit of measurement for angles in mathematics. It is defined as the angle formed at the center of a circle by an arc that is equal in length to the radius of the circle. In other words, a radian is the angle that subtends an arc equal in length to the radius of the circle.

The radian is used as a unit of measurement because it provides a convenient and natural way to describe angles in terms of their relationship to circles. It allows for the calculation of angles in terms of lengths, making it easier to solve problems involving circular motion and trigonometry. The conversion between degrees and radians is given by the formula: 1 radian = 180/π degrees, where π is the mathematical constant pi.

To convert degrees to radians, use the formula: radians = (degrees × π) / 180.

For 75° 30', the conversion to radians is:

radians = (75° 30' * π) / 180 = (75 + 30/60) * π / 180 = 1.309 radians.

Answer:

$773.55

Step-by-step explanation:

To find the total cost of the camera with the sales tax included, you need to calculate the amount of sales tax and add it to the listed price of the camera.

The sales tax rate is given as 9.75%. To convert this to a decimal, divide the percentage by 100: 9.75/100 = 0.0975

To find the amount of sales tax, multiply the listed price of the camera by the sales tax rate as a decimal: $704.95 x 0.0975 = $68.60

To find the total cost of the camera, add the amount of sales tax to the listed price: $704.95 + $68.60 = $773.55

So the total cost of the camera with the sales tax included is $773.55

The units of R'(7) are gallons/hour/hour, or equivalent gallons/hour is 6 = 0.15 gallons per hour and  2 R(t) dt using the average Riemann sum with four equal length partitions is 383.04 gallons.

(a)  R'(7), you can use the mean rate of change formula.

R'(7) ≈ [R(10) - R(4)] / [10 - 4]

With the data from the table it looks like this:

R(10) = 11.3 gallons per hour

R(4) = 10.4 gallons per hour

For this,

R'(7) ≈ (11.3 - 10.4) / 6 = 0.15 gallons per hour

The units of R'(7) are gallons/hour/hour, or equivalent gallons/hour squared.

(b) To approximate 2 R(t) dt using the average Riemann sum with four equal length partitions, we can use

Δt = (24 - 0) / 4 = 6

2 R(t) dt ≈ 2Δt [R(1.5Δt) + R(4.5Δt) + R(7.5Δt) + R(10.5Δt)]

With the data from the table it looks like this:

R(1.5Δt) = R(4.5) = 10.4 gallons/hour

R(4.5Δt) = R(10.5) = 11.3 gallons per hour

R(7.5Δt) = R(16.5) = 10.2 gallons/hour

R(10.5Δt) = R(22.5) = 9.6 gallons per hour

For this,

2 R(t) dt ≈ 2(6) [10.4 + 11.3 + 10.2 + 9.6] = 383.04 gallons

The approximate unit of integral is the gallon.

Yes, it is possible to have a graph of a function that is symmetric about both the y-axis and the origin. This means that if (x, y) is a point on the graph, then (-x, y) and (x, -y) are also points on the graph.

In other words, the function has both reflectional symmetry about the y-axis and rotational symmetry about the origin. An example of such a function is y = x², which is a parabolic function that opens upwards and is symmetric about both the y-axis and the origin.

A graph is symmetric about the y-axis if the graph is unchanged when reflected over the y-axis. This means that for any point (x,y) on the graph, the corresponding point (-x,-y) will also be on the graph. A graph is symmetric about the origin if the graph is unchanged when reflected over the origin.

Therefore, This means that for any point (x,y) on the graph, the corresponding point (-x,y) will also be on the graph. When a graph is symmetric about both the y-axis and the origin, it means that the graph is unchanged when reflected over either the y-axis or the origin.
