Answer the following True or False:
If lim f(x) = – 3 then f(x) is continuous at x = – 2.
2 - 2

Answers

Answer 1

False; consider as a counterexample the function f : ℝ→ℝ defined by

[tex]f(x)=\begin{cases}-3&\text{for }x\neq2\\0&\text{for }x=2\end{cases}[/tex]

Clearly f approaches -3 as x gets closer to -2, but neither limit from either side is equal to the function's value at x = 2 (that is, -3 ≠ 0), so f is not continuous.

what is 36 divided by 6 equals blank sold 36000 divided by 6 equals ​

Answers

Answer: Quotient of 36 and 6 will be 6. Since, 36/6 = 6 with remainder 0.Therefore, the answer to what divided by 2 equals 36 is 72. You can prove this by taking 72 and dividing it by 2, and you will see that the answer is 36. Tip: For future reference, when you are presented with a problem like "What divided by 2 equals 36?", all you have to do is multiply the two known numbers together.hope this helps have a awesome day/night❤️✨

Step-by-step explanation:

The correct calculations show that 36 divided by 6 equals 6, and 36000 divided by 6 equals 6000.

When we divide 36 by 6, the quotient is 6. Therefore, 36 divided by 6 equals 6.

Similarly, when we divide 36000 by 6, the quotient is 6000. Therefore, 36000 divided by 6 equals 6000.

To calculate these divisions, we divide the dividend (36 and 36000) by the divisor (6) to find the quotient.

In the case of 36 divided by 6, we have 36 ÷ 6 = 6.

For 36000 divided by 6, we have 36000 ÷ 6 = 6000.

Hence, the correct calculations show that 36 divided by 6 equals 6, and 36000 divided by 6 equals 6000.

Bill buys a large can of paint. The size of the can is measured in which unit?

Answers

Answer:

Barometer i think im not sure

Step-by-step explanation:

Pressure is a mechanical (non-electrical and non-magnetic) measure. All mechanical measures can be derived from just three basic mechanical units. Which three we use is actually arbitrary. This means that using three we can produce or define all other mechanical measures by multiplying or dividing some combination of the chosen three.

Most measuring systems use time, length, and mass as the basic three in which case pressure would be mass / (time * time * length * length). Compare that with kilogram per (meter*meter * second*second) which is also called a Pascal.

Another measuring system might use time, length, and force as the three basic measures. Here mass is omitted in place of force. Nothing is lost because mass and force can be written in terms of the other with the help of time and length. In this case pressure would be force / (length*length). Compare this with Newton per meter*meter which also defines a Pascal.

How pressure is measured in practice is another good question. The standard method is to use some device that employs a medium to compare the unknown pressure to some known familiar pressure. Mercury tubes illustrate this nicely and are still used in laboratories. They work because mercury is a very dense fluid. A lighter fluid can push upon and move a column of mercury but cannot pass through it.

Measuring the movement of mercury when a known pressure is applied to one end reveals the pressure at the other end. The persistence of millimeters of mercury (mmHg) as a unit for reporting pressure is testament to this method. Other pressure gages work by employing something like springs or strain sensors calibrated to mimic the readings that a mercury tube would report.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Let the missing term would be x

The equation is given in the question, as follows:

24 + 30 = 6(4 + x)

We have to determine the value of x

As per the given question, we have

24 + 30 = 6(4 + x)

Apply the distributive property,

24 + 30 = 24 + 6x

Combine the likewise terms in the above equation,

6x = 30

x = 30/6

Apply the division operation,

x = 5

Thus, the required missing term would be 5.
