2 × 10³ is an exponential expression, which has a standard form as 2000.

Exponential expressions are just a way to write powers in short form. The exponent

indicates the number of times the base is used as a factor. So in the case of 32 it can

be written as 2 × 2 × 2 × 2 × 2 = 25, where 2 is the “base” and 5 is the “exponent”.

The expanded form comes in a variety of forms. Exponents are employed. The expanded form of that expression is what is stated above.

One more makes use of multipliers like 1, 10, 100, 1000, and so forth. The expression broadens in that form as...

10^2 = 1×100

Another expanded form uses the expanded form's individual digits, setting the others to zero.

10^2 = 100

The standard format is...

10^2 = 100.

Answer: 37.33 % of items cost less than $7.5

Step-by-step explanation:

To find the percentage of items that cost less than $7.5, we would need to know the probability distribution function of the cost per item, as well as the specific parameters of the distribution (such as the shape parameter).

Since the information provided is that the cost per item follows an exponential distribution and the mean cost per item is $10.5,

We can use the cumulative distribution function (CDF) of the exponential distribution which is

F(x) = 1 - e^(-λx)

where x is the cost of the item, λ is the rate parameter and e is the base of the natural logarithm.

We know the mean is $10.5 , and in an exponential distribution the mean and the rate parameter are equal, so we can say λ = 1/10.5

To find the percentage of items that cost less than $7.5, we need to find the probability that X < 7.5, which is the same as finding F(7.5)

So, F(7.5) = 1 - e^(-λ*7.5) = 1 - e^(-0.714)

Then, we need to convert this probability to percentage, so we need to multiply it by 100

F(7.5) = (1 - e^(-0.714)) * 100 = 37.33 %

Therefore, 37.33 % of items cost less than $7.5

An inequality to represent the dollar amounts d in cash and prizes Regan can win is p + d ≥ 500.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, Regan won the grand prize at a store giveaway. The grand prize winner is guaranteed to win at least $500 in cash and prizes.

Let d represent the amount of cash in dollars and p represent the amount of prizes.

Since the  grand prize winner is guaranteed to win at least $500,

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that cylindrical jar contains three glass balls each has a diameter of 2cm

Let us find the volume of each sphere.

Volume of sphere=4/3×πr³

As diameter is 2 then radius is 1.

Volume of each sphere=4.186

Volume of three spheres=3×4.186=12.56

Now let us find the volume of cylinder.

The diameter of cylinder will be 2 and height is 6 cmas there are 3 spheres of diameter 2cm.

Volume of cylinder=πr²h

Answer:

Step-by-step explanation:

Problem 1

The resolution formula for arcseconds is 1 radian = 206265 arcseconds.

To convert 1.22 radians to arcseconds, we can use the conversion ratio of 1 radian = 206265 arcseconds: 1.22 radians x 206265 arcseconds/radian = 252438.3 arcseconds

Problem 2

a. Literal equation: D = (Wavelength / (2* arcsecond))

Variable to solve for: D (diameter of camera lens)

b. Chlorophyll reflects green light. The wavelength of green light on the electromagnetic spectrum is approximately 550 nanometers.

c. D = (Wavelength / (2* arcsecond))

D = (550 x 10^-9 meters / (2* 6 x 10^-6 radians))

D = (550 x 10^-9 meters / 12 x 10^-6 radians)

D = (550 / 12) x 10^-9 meters / 10^-6 radians

D = 45.83 x 10^-3 meters or 0.04583 meters

Problem 3

The graph would have wavelength in nanometers on the x-axis and diameter of lens or mirror in meters on the y-axis.

The graph would start at 100 nanometers and end at 10,000 nanometers on the x-axis and the y-axis would start at 0 and end at the diameter of the lens or mirror needed to obtain a resolution of 1 arcsecond.

The graph would show that as the wavelength increases, the diameter of the lens or mirror needed to obtain a resolution of 1 arcsecond would decrease. At a wavelength of 10,000 nanometers (10 microns), the diameter of the camera would be 0.04583 meters.

The spatial resolution of a telescope depends on the size of the telescope's aperture and the wavelength of light being detected.

The spatial resolution of a telescope has an inverse relationship with the wavelength of light being detected and the telescope's diameter. As the wavelength increases, the spatial resolution decreases, and as the diameter of the telescope increases, the spatial resolution increases.

The spatial resolution for our eyes is about 1 arcminute.

Spatial resolution is related to remote sensing in that it refers to the ability of a sensor to distinguish between two objects that are close together. A higher spatial resolution allows for more detailed information to be gathered from an image.

The GOES (Geostationary Operational Environmental Satellite) detects weather patterns, temperature, humidity, and other atmospheric conditions. It uses remote sensing technology to gather and transmit data to meteorologists for weather forecasting and monitoring.

Answer:

Problem 1 - If 1 radian = 206265 arcseconds, what is the resolution formula for arcseconds? Convert 1.22 Radian to arcseconds using ratio. Show your work with units.

Problem 2 - A biologist wants to study deforestation with a satellite camera with a pixel resolution of 10 meters/pixel, which at the orbit of the satellite corresponds to an angular resolution of 6 arcseconds. You have already determined the value for arc seconds from problem number one. To measure the loss of plant matter, she detects the reflection by the ground of chlorophyll, which is the most intense at a wavelength of ___________ (1 nanometer = 10-9 meters) [Use the Electromagnetic Spectrum Below to fill in the blank]. To determine the wavelength, use the electromagnetic spectrum visible light section; what color should chlorophyll reflect? Determine the wavelength using the diagram below.

How to solve literal equations help here.

b. What color should chlorophyll reflect? _____________ Where is the wavelength on the spectrum as far as nanometers? ___________ (this is the wavelength you will use for calculation). Not everyone will have the same wavelength, but it should be similar.

c. Use your literal equation and solve the diameter of the camera lens (You should show all work, and your answer should have one significant figure with units in your response). Circle the answer.

Problem 3 –Since you have already determined the diameter of a lens required for an object with your nanometers from problem #2, you can use this direct relationship to determine the necessary diameter to 10 microns (10 microns = 10,000 nanometers). Choosing the diameter of the lens depends on the wavelength. It would help if you constructed a graph showing the diameter of the lens or the mirror in meters needed to obtain a resolution of 1 arcsecond from far-ultraviolet wavelengths of 200 nanometers to infrared wavelengths of 10 micrometers.

Question: Construct a graph that shows the diameter of a lens or mirror needed to obtain a resolution of 1 arcsecond from far-ultraviolet wavelengths of 100 nanometers to infrared wavelengths of 10 microns (10,000 nanometers).

Answer:  Ryan should sell his CDs for $13 to maximize his revenue.

Step-by-step explanation:

To find the price at which Ryan should sell his CDs to maximize his revenue, we need to use the information provided about the relationship between price and sales, and the formula for revenue (price x quantity sold).

Step 1: Identify the relationship between price and sales. We know that a $1 increase in the price of a CD leads to a drop of 5 CDs per week in sales.

Step 2: Create an equation that relates price, quantity sold, and revenue. Let P be the price of a CD, Q be the quantity sold, and R be the revenue. Then, we have R = P x Q

Step 3: Create a table that shows the relationship between price, quantity sold, and revenue.

Price Quantity Sold         Revenue

10       80                            800

11       75                              825

12      70                                     840

13     65                                        845

14     60                                         840

15     55                                        825

16     50                                   800

17     45                                  785

18     40                                720

19     35                                      665

20     30                                              600

Step 4: Identify the price that maximizes revenue. From the table we can see that the revenue is maximum at $13 which is 845 and this is the price at which Ryan should sell his CDs to maximize his revenue.

Therefore, Ryan should sell his CDs for $13 to maximize his revenue.
