Answer:

B -- scalene acute triangle

Step-by-step explanation:

None of the measures are >90 degrees. All of the lengths and angles are different sizes. This means that the triangle is an acute scalene triangle

14. The circle graph shows the results of an employment survey of 800

MariettaO [177]

Answer:

480 people were unemployed full time

Step-by-step explanation:

First thing to do here is to check the percentage of people that were unemployed full time

Looking at the graph, this is equal to 60%

This means that 60% of the total 800 are unemployed full time

Mathematically, that would be 60/100 * 800 = 480 people

A two-state system is in an environment at temperature 500 K. The energy of state 1 is 4.1e-20 J, and the energy of state 2 is 5

katovenus [111]

Complete Question

A two-state system is in an environment at temperature 500 K. The energy of state 1 is $E_1=4.1e-20 J$ , and the energy of state 2 is $E_2= 5.7e-20 J$ . Let P(1) be the probability of finding the system in state 1, and be the probability of finding the system in state 2. What is the ratio P(2)/P(1)

Answer:

$X=0.0984$

Step-by-step explanation:

From the question we are told that:

Temperature T=500 K

Energy of state 1 $E_1=4.1e-20 J$ ,

Energy of state 2 is $E_2= 5.7e-20 J$

Generally the equation for Probability of finding the system in state is mathematically given by

$P(1)=e ^{\frac{-E_1}{KT}}$

Therefore

For Probability of finding the system in state 1 $P(1)$

$P(1)=e ^{\frac{-E_1}{KT}}$

Where

K is Boltzmann constant

$K=1.38*10^{-23}$

$P(1)=e ^{\frac{-(4.1e-20 J)}{1.38*10^{-23}*500}}$

For Probability of finding the system in state 1 $P(2)$

$P(2)=e ^{\frac{-(5.7e-20 J)}{1.38*10^{-23}*500}}$

Generally the equation for The Ratio of $P(2)$ and $P(2)$ is mathematically given by

$X=\frac{P(2)}{p(1)}$

$X=e ^{\frac{E_1-E_2}{KT}}$

$X=e ^{\frac{-(4.1-5.7)e-20 J)}{1.38*10^{-23}*500}}$

$X=0.0984$

I need to find the table of -csc theta

AVprozaik [17]

See below for the table of -csc theta

<h3>How to determine the table?</h3>

The function is given as:

-csc theta

Rewrite properly as:

$-\csc(\theta)$

This is calculated as:

$-\csc(\theta) = -\frac{1}{\sin(\theta)}$

Set $\theta$ to 0, 30, 45, 60 and 90

$-\csc(0) = unde fined$

$-\csc(30) = -2$

$-\csc(45) = -\sqrt 2$

$-\csc(60) = -\frac{2\sqrt 3}{3}$

$-\csc(90) = -1$

So, the table of -csc theta is

<u>Angle -csc theta </u>

0 undefined

30 -2

45 -√2

60 -2/3 √3

90 -1

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. A rectangle is shown wi

Verizon [17]

Answer:

x² + 23x + 49

Step-by-step explanation:

Since the area of a rectangle is: A = l x w, where l = length and w = width, we can find the overall area of the shaded region by multiplying the entire area and subtracting the smaller area of the unshaded square:

(2x + 5)(x + 10) - (x + 1)² or (2x + 5)(x + 10) - (x² + 2x + 1)

Distribute/FOIL:

2x² + 20x + 5x + 50 - x² - 2x -1

Combine like terms:

x² + 23x + 49
