Consider sides AB (length 4) and BC (length 15) of the triangle.

Consider the angle between AB and BC is slightly less than 180 degrees. To get from point A to point C, we have to travel almost the entire length of A to C, which is from A to B and then B to C, so a bit less than 19 cm.

Consider the angle between AB and BC is slightly more than 0 degrees. To get from point A to point C, we subtract the length of AB (because we're already further along BC), so 15 - 4, a bit greater than 11.

3x - 20 + 3x + 5 = 111

Combine like terms
6x - 15 = 111

Add 15 to each side.

Evaluate
6x = 126
x = 21

Plug x back into the equation for angle EFG.
EFG = 3x -20
3(21) - 20
EFG = 43 degrees

Answer:

[tex] m\angle EFG =43\degree[/tex]

Step-by-step explanation:

[tex] m\angle EFG +m\angle GFH = m\angle EFH\\\\

(3x-20)\degree + (3x+5)\degree =111\degree \\\\

(3x-20+3x +5)\degree =111\degree \\\\

(6x-15)\degree =111\degree \\\\

(6x-15) =111 \\\\

6x = 111 + 15\\\\

6x = 126\\\\

x = \frac{126}{6}\\\\

x = 21\\\\

m\angle EFG = (3x-20)\degree\\\\

m\angle EFG = (3\times 21-20)\degree\\\\

m\angle EFG = (63-20)\degree\\\\

m\angle EFG =43\degree\\[/tex]

Answer:

Table B is a function

Step-by-step explanation:

The relation shown in a table is NOT a function if the same input value gives different output values.

In Table A, input Taurus gives different outputs, so Table A is NOT a function.

In Table B, there are no repeated inputs, so Table B IS a function.

5. Select ALL of the following expressions that are linear functions (they do not need to be in slope-intercept form).

y = 3x - 2
y + x2 = 12
y = x2 + 2x

3x + -y = 24

Answers

Answer:

The following are the LINEAR functions.

[tex]2x\:+\:4\:=\:3x\:-\:8[/tex][tex]y = 3x - 2[/tex][tex]1[/tex][tex]3x\:+\:-y\:=\:24[/tex]

Step-by-step explanation:

We know that linear functions are the equations with a straight line graph in an XY plane.

Also, a linear function is a function of the form

[tex]f(x)=mx+b[/tex]

where m is the slope and b is the y-intercept. The only power of the variable is 1.

So, from the given expressions we can determine that:

1) [tex]y^2=\:5x\:+2[/tex]

[tex]y^2=\:5x\:+2[/tex] is NOT a linear function because the power of y is 2, hence the graph won't be a straight line. Therefore, it is not a linear function

2) [tex]2x\:+\:4\:=\:3x\:-\:8[/tex]

[tex]2x\:+\:4\:=\:3x\:-\:8[/tex]

[tex]x=12[/tex]

This is a linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1

3) [tex]y = 3x - 2[/tex]

[tex]y = 3x - 2[/tex] is a linear function because it is of the form [tex]f(x)=mx+b[/tex] and the power of its x and y variables is 1. Hence, the function has a straight line graph.

4) [tex]y\:+\:x^2\:=\:12[/tex]

[tex]y\:+\:x^2\:=\:12[/tex] is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.

5) [tex]y\:=\:x^2\:+\:2x[/tex]

[tex]y\:=\:x^2\:+\:2x[/tex] is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.

6) [tex]1[/tex]

[tex]1[/tex] is a constant function and a constant function is also considered linear in this context, as it is a polynomial of degree [tex]0[/tex] or is the [tex]0[/tex] polynomial.

7) [tex]3x\:+\:-y\:=\:24[/tex]

[tex]3x\:+\:-y\:=\:24[/tex] is a linear function as the power of its x and y variables is 1. Hence, the function has a straight line graph. Therefore, it is a linear function.

In a summary, the following are the LINEAR functions.

[tex]2x\:+\:4\:=\:3x\:-\:8[/tex][tex]y = 3x - 2[/tex][tex]1[/tex][tex]3x\:+\:-y\:=\:24[/tex]

Sir Roger Bannister, the first man to break the four-minute-mile record, knew what it was like to break barriers.Learning a Passion Roger Bannister was born in Harrow, England, in 1929. Since his parents couldn't afford to send him to college, he worked to win scholarships to study medicine at Oxford. Bannister had two loves: studying medicine and running track. He worked hard to do well at both. Because of his studies, Bannister had less time for track practice than other athletes. Most athletes trained at least six days a week. Bannister trained only two to three times a week. In the 1952 Olympic Games, Bannister ran the 1500m race but finished fourth. Many said this was due to his lack of training. Bannister decided it was time to get serious. He focused on doing what everyone in the world thought was impossible. He wanted to break the four-minute-mile barrier.Setting a Goal No one in history had ever run a mile in less than four minutes, although several had tried. For decades, physicians believed that running a mile too fast would cause heart failure. Bannister knew he could set a new world record by working hard. Bannister believed that pushing himself beyond the pain would make him a winner. That is just what Bannister did on May 6, 1954, at Iffley Road Track in Oxford. On a cold, wet track, Roger Bannister broke the four-minute-mile barrier with a time of 3:59.4. Two other runners helped him set a fast pace. Then Bannister relied on his training to run the first three laps of the track in 3:01. During the final lap of the race against the clock, Bannister knew he could finish the race in less than 59 seconds. He broke away from the other runners and flew down the last two curves of the track at record speed. As he crossed the finish line, he collapsed into the arms of his friend Reverend Nicholas Stacey. Bannister was out of breath and out of energy, but he knew he had broken the world record. Bannister accomplished a great moment in history that day. After breaking the four-minute-mile barrier, Bannister competed in a few more races. He ran his personal record of 3:43.8 in the 1500m in the European Championship. That was Bannister's last race. In August of 1954, he retired at the age of 25 to focus on what he considered his true contribution to societyhis research in the field of neurology, the study of the nerves and the nervous system.Making a Difference In 1975, two decades after his feat, Roger Bannister was knighted by the Sports Council of England. He had done what no man thought was possible. However, Bannister knew his athletic glory was fleeting. He felt that his work as a neurologist was the real accomplishment of his life. For over 40 years, he worked in neurology, helping patients who suffered serious neurological disorders. To honor his work and dedication as a neurologist, St. Mary's Hospital in London named a lecture hall after Dr. Bannister. In the lecture hall, the famous stopwatch used to time Bannister's mile is on display. In July of 2012, Bannister was honored to be elected as one of the Olympic torchbearers. He carried the flame into the Oxford track stadium that was named for him. Of his neurology career and his track achievements, as the greatest runner ever, Bannister claims that working hard is the secret to his success.10What can be inferred by referring to the timeline? A. Bannister was more well known as a neurologist than as a track and field star. B. Bannister did not value his time as a runner and never participated in sports again. C. Despite retiring from track and field at a young age, Bannister was still involved with sports throughout his life. D. After retiring from track and field at a young age, Bannister continued to run. How do you tell someone you don't agree with them? A.J'ai raison B. Je suis d'accord C. J'ai tort D.Je ne pas d'accord. A patio 44, feet wide is being constructed next to a house.
