2. What is a positive coterminal angle to -123° that is between 500° and 750° and a negative coterminal angle to -123° that is between −300° and −500°?
Answer:
The two angles are 597° and -483°
Step-by-step explanation:
A coterminal angle to a random angle A, is an angle that has the same terminal side as A.
If we know the angle A, all the coterminal angles to A can be written as:
A + n*360°
Where n is an integer number.
In this case, we know that:
A = -123°
And we want to find a coterminal angle that is between 500° and 750°
Then we can do:
X = -123° + n*360°
And find the value of n such that X is between the desired values.
if we use n = 1 we get:
X = -123° + 1*360° = 237°
This is not enough, we can discard it.
If we use n = 2, we get:
X = -123° + 2*360° = 597°
This is a coterminal angle to -123°, and is in between 500° and 750°.
Now we want to find a coterminal angle to -123° that is in between -300° and -500°, we can do the same thing as before, but now we can try with negative values of n.
We can start with n = -1, then:
X = -123° - 1*360° = -483°
This is a coterminal angle to -123°, and is in between -300° and -500°.
Then the two angles are:
597° and -483°

Five friends go to the movies. They each pay $9 to get in and $8 for a popcorn and drink combo.
a) Write two different expressions to find the total cost of the outing.
b) Evaluate each expression. Which expression was easier to evaluate? Justify your choice.
Answer:
x=5(9+8)
add 9+8 to get 17
multiply 17 by 5
answer: $85
(5x9)+(5x8)=x
multiply 5x9 to get 45
multiply 5x8 to get 40
add 45 and 40
answer: $85
The first expression was easier to evaluate because it required less steps.

In order to graph a line your equation must be set equal to y. If I gave you the following equation would you be able to graph it in the form it is given? If not, rewrite the equation so that you could graph it. - 6x + 12y = 9
Answer:
Step-by-step explanation:
Graphing the equation in the form it is given is eventually hard so we always rewrite the equation in the form of y. Lets rewrite the equation in the form of y.
[tex]-6x+12y=9\\12y=6x+9\\\\y=\frac{6x+9}{12} \\\\y=\frac{6x}{12}+\frac{9}{12} \\\\y=\frac{1}{2}x+\frac{3}{4}[/tex]
now if we compare it to our slope-intercept form which is
[tex]y=mx+b[/tex]
m is the slope which is 1/2 which tells us that if the slope is positive the graph is a positive slope means that two variables are positively related that is, when x increases so does y, and when x decreases y also decreases. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises, and b is the y-intercept which is 3/4.
Intercept means where the line intersects the specific axis. In this case b is y-intercept which is 3/4 which means the line intersects the y-axis at 3/4
so we have our first point (0 , 3/4)
now in order to graph the line we need one more point that is the x-intercept which means where the line would intersect the x-axis the coordinate would be (x , 0) so lets insert this coordinate into our equation that we rewrote above.
[tex]y=\frac{1}{2}x+\frac{3}{4} \\\\0=\frac{1}{2}x+ \frac{3}{4}\\\\-\frac{3}{4}=\frac{1}{2} x\\\\-6=4x\\\\\frac{-6}{4}=x \\\\x=\frac{-3}{2}[/tex]
so our x-intercept is (-3/2 , 0)

b. 3 ice cream cones cost $3.75.
At this rate, how much do 2 ice cream cones cost?
Answer:
2.50
Step-by-step explanation:
Lets find the unit rate first! 3.75/3 because that is the problem. Now once we divide that we get 1.25. With 1.25 we multiply by 2 to get your answer of 2.50!

Nicholas started a canned-food drive at school. The equation representing this is y = 235x + 15, where x is the number of days, and y is the number of cans collected. Explain how to determine how many days it would take to collect 2600 cans.WILL GIVE BRAINLIEST
Answer:
well, 11 days
Step-by-step explanation:
if you were to put take out the y and put 2600 in the y place (2600=235x+15)
you solve that, and will come to 11 days
further explaining:
2600-15 = 2585
2585 / 235 = 11
( I'm not sure if this is right, the question is worded weird and almost doesn't make sense)
but I think it is looking for substitution
Hope this helps!
Answer:
I am given a number of cans, which is y, and I need to find the number of days, which is x. To do this, I would substitute 2600 for y, to get 2600 = 235x + 15. Solving for x, I would get x = 11. Thus, it would take 11 days to collect 2600 cans.

Cos(0.5)+cos(0.5+2(3.14159265))+cos(0.5+4(3.14159265))
Answer:
2.63274768567
Step-by-step explanation:
First, note that 3.1415... is p, so 2(3.1415...) is 2pi and 4(3.1415...) is 4pi.
2pi and 4pi are full rotations, which will lead to the same cosine (i.e. cos(x) = cos (x+2pi) = cos(x+4pi) = ... = cos (x+2k*pi)).
So, the expression equals cos0.5 + cos 0.5 + cos0.5 = 3cos0.5 = 3(0.87758256189) = 2.63274768567

What is the population density of the US if the area of the United States is 4,000 square miles?
Answer:
82050 people/mi^2
Step-by-step explanation:
The population of the US is 328.2 million people and the area of the US is 4000 mi^2 as given. The population density is found by (population)/(area), so we input our values in:
Population density = 328, 200, 000/4000 = 82050 people/mi^2
