For water to be a liquid, its temperature must be within 50 Kelvin of 323 Kelvin. Which equation can be used to determine the minimum and maximum temperatures between which water is a liquid?

Answers

Answer 1
Answer:

Answer:

| T-50 |= 323

Step-by-step explanation:

For water to be a liquid, its temperature must be within 50 Kelvin of 323 Kelvin

LEt T be the temperature

Temperature must be within 50 Kelvin of 323 Kelvin

So the difference is 50 , that is the temperature T is between 323-50 and 323+50

we use absolute function

|T-50|= 323

So the equation used to determine the minimum and maximum temperatures is | T-50 |= 323
Answer 2
Answer: abs(T-50)=323 Where T is in degrees Kelvin. abs () means absolute value. So T=323 plusorminus 50

Percy works two part-time jobs to help pay for college classes. On Monday, he works 3 hours at the library and 2 hours at the coffee cart and earns $36.50. On Tuesday, he works 2 hours at the library and 5 hours at the coffee cart and earns $50. His hourly wage at the library, x, and hourly wage at the coffee cart, y, can be determined using the system of equations below.3x + 2y = 36.50 2x + 5y = 50.00 At which job does Percy earn the greater hourly wage?

At Southwest HS, the number of student in band is 1 3/4 times the number in orchestra. If 56 students are in orchestra, how many are in band?

Answers

It is important to take note of all the information's that are given in the question. It would be easy to solve the problem based on the information's given in the question.
Number of students in orchestra = 56
The number of students in band is = 1 3/4 times that are in orchestra
Then
Total number of students in band = (7/4) * 56
                                                     = 7 * 14
                                                     = 98
So 98 students are there playing in the band. I hope the answer and the procedure is clear to you. In future you can use this procedure to solve similar kind of problems without requiring any help from outside.
56 students* (1 3/4)= 98 students.

There are 98 students in the band~

Complete the statements about the key features of the graph of f(x) = x5 – 9x3.As x goes to negative infinity, f(x) goes to ________ infinity, and as x goes to positive infinity, f(x) goes to _______ infinity.

Answers

we have

f(x) = x^(5) -9x^(3)

using a graph tool

see the attached figure

in the graph observe that

As x goes to negative infinity-------> f(x) decreases

and

As x goes to positive infinity-------> f(x) increases

therefore

the answer is

As x goes to negative infinity, f(x) goes to negative infinity, and as x goes to positive infinity, f(x) goes to positive infinity.
