The volume of solution in a test tube is measured to be 0. 0067 liter. Which digits in the measurement are significant figures?.

SAT

4 0

Answer:

6 & 7

Explanation:

Given data:

Volume of solution measured = 0.0067 L

To determine:

The number of significant figures

Significant figures are the number of digits that accurately describe a measured value.

As per the rules:

All non-zero digits are significant

Leading zero's i.e. the zero's after a decimal which comes before a non-zero digit are not significant

Hence in the given value 0.0067, there are 2 significant figures (6 &7)

Hurricanes usually last much longer than other types of storms. Some can last a week or longer. As a hurricane makes landfall an
Reptile [31]

Answer:

There are six widely accepted conditions for hurricane development:

1. The first condition is that ocean waters must be above 26 degrees Celsius (79 degrees Fahrenheit). Below this threshold temperature, hurricanes will not form or will weaken rapidly once they move over water below this threshold. Ocean temperatures in the tropical East Pacific and the tropical Atlantic routinely surpass this threshold.

2. The second ingredient is distance from the equator. Without the spin of the earth and the resulting Corioles force, hurricanes would not form. Since the Corioles force is at a maximum at the poles and a minimum at the equator, hurricanes can not form within 5 degrees latitude of the equator. The Corioles force generates a counterclockwise spin to low pressure in the Northern Hemisphere and a clockwise spin to low pressure in the Southern Hemisphere.

3. The third ingredient is that of a saturated lapse rate gradient near the center of rotation of the storm. A saturated lapse rate insures latent heat will be released at a maximum rate. Hurricanes are warm core storms. The heat hurricanes generate is from the condensation of water vapor as it convectively rises around the eye wall. The lapse rate must be unstable around the eyewall to insure rising parcels of air will continue to rise and condense water vapor.

4. The fourth and one of the most important ingredients is that of a low vertical wind shear, especially in the upper level of the atmosphere. Wind shear is a change in wind speed with height. Strong upper level winds destroy the storms structure by displacing the warm temperatures above the eye and limiting the vertical accent of air parcels. Hurricanes will not form when the upper level winds are too strong.

5. The fifth ingredient is high relative humidity values from the surface to the mid levels of the atmosphere. Dry air in the mid levels of the atmosphere impedes hurricane development in two ways. First, dry air causes evaporation of liquid water. Since evaporation is a cooling process, it reduces the warm core structure of the hurricane and limits vertical development of convection. Second, dry air in the mid levels can create what is known as a trade wind inversion. This inversion is similar to sinking air in a high pressure system. The trade wind inversion produces a layer of warm temperatures and dryness in the mid levels of the atmosphere due to the sinking and adiabatic warming of the mid level air. This inhibits deep convection and produces a stable lapse rate.

6. The sixth ingredient is that of a tropical wave. Often hurricanes in the Atlantic begin as a thunderstorm complex that moves off the coast of Africa. It becomes what is known as a midtropospheric wave. If this wave encounters favorable conditions such as stated in the first five ingredients, it will amplify and evolve into a tropical storm or hurricane. Hurricanes in the East Pacific can develop by a midtropospheric wave or by what is known as a monsoonal trough.

nydimaria [60]

A salesman marketing CRM software would ask inquiries regarding maintaining and preserving customer relationships.

<h3>Why is Customer Relationship Vital in Business Setting?</h3>

Customers' relationships are vital for company owners to establish long-term success. Developing a working connection with consumers is crucial for strategic and long-term success.

Customers feel more comfortable and engaged with a company when they have a solid connection based on trust and communication, which may lead to higher customer turnover and recurrent purchases.

Questions on customer wants can include;

  • "How do you keep in contact with potential customers and maintain connections with them?"

A salesman marketing CRM software would ask inquiries regarding maintaining and preserving customer relationships within the preapproach phase to gain a deep understanding of his customer's wants.

Review the table of values for function h(x). x h(x) 9.9 12.7 9.99 12.97 9.999 12.997 9.9999 12.9997 10 undefined 10.0001 18.500
defon

As h(x) approaches 10+ the limit is given as 18.5

<h3>What is limit in mathematics?</h3>

The limit in mathematics has to do with the value that a function would approach as the input in the limit approaches a particular value.

It is when a function would be made to approach output at a particular input value. The concept is very important in calculus as well as analysis in mathematics. They help to define integrals, derivatives as well as continuities in mathematics.

<h3>How to solve for the limit</h3>

The x equation that we have in the question is given as

x = (10+n)

We are to find the limit of lim h(10+n)

This is as h tends towards 10.

h→10

When we go to the table we would observe what happens as 10 moves towards this value. In the given table we would have h as it tends towards 10. In the right hand side of this table we would see that as X is moving towards 10, the value changes to 18.5

Hence the answer to this question is 18.5

How to solve Linear equalities and linear inequalities
LekaFEV [45]
Linear equation

Example 1
Solve for x: 3 x – 7 > 20.

equation

To check the solution, first see whether x = 9 makes the equation 3 x – 7 = 20 true. Even though 9 isn't a solution, it's a critical number or dividing point and is important to finding the solution.

equation

Now, choose a number greater than 9—10, for example, and see whether that makes the original inequality true.

equation

This is a true statement. Since it is impossible to list all the numbers that are greater than 9, use “set builder” notation to show the solution set.

{ x| x > 9}

This is read as “the set of all x so that x is greater than 9.” Many times, the solutions to inequalities are graphed to illustrate the answers. The graph of { x| x > 9}is shown in Figure 1.

Figure 1. Note that 9 is not included.

Example 2
Solve for x: equation.

The LCD for the denominators in this inequality is 24. Multiply both sides of the inequality by 24 as you would have had this been an equation.

equation

At this point, you can isolate x on either side of the inequality.

equation

In the final step on the left, the direction is switched because both sides are multiplied by a negative number. Both methods produce the final result that says that x is a number less than equation. The check is left to you. The solution set is expressed as

equation

The graph of this solution set is shown in Figure 2.

Figure 2. Note the hole at equation.
