Answer: They are skew and will never instersect.
Step-by-step explanation: First of all, they will never instersect because they are in the parallel planes. They are also skew because in the 3 dimensional geometry, they are also not parallel because they can be different directions.
Answer:
They are skew and will never intersect.Step-by-step explanation:
WE know that lines are in different planes which are parallel, this means that those planes have the same angle of direction.
If planes are parallel, then all lines inside them are skew, that is, line a and line b will never intersect and they aren't necessarily has to be parallel.
For example, imagine you are in a apartment, parallel planes are the roof and the floor, they are parallel, that is, the will never intersect each other. So, if you have a ruler attached to the roof and another ruler on the floor, you will see that those rulers are not necessarily parallels, and they won't intersect each other because, they have the same angle of direction.
Therefore, the right answer is "They are skew and will never intersect"
a juice company produced 8064 cartons of juice in 21 days each day they produced the same the same number of carton and delivered those carton 216 area of coffee shops the cart the cartons were delivered in cases of six cartons per case and each coffee shop received an equal number of cases in each delivery. how many cases were delivered to each coffee shop each day
Answer:
The each coffee shops receives 4 cases of juice everyday.
Step-by-step explanation:
The juice company produced 8064 cartons of juice in 21 days each day they produced the same number of cartons.
Therefore, each day the company produces [tex]\frac{8064}{21} = 384[/tex] cartons.
The juice company delivers those cartons in 16 areas of coffee shops.
So, each coffee shop receives [tex]\frac{384}{16} = 24[/tex] cartons of juice.
Now, the cartons were delivered in cases of six cartons per case and each coffee shop received an equal number of cases in each delivery.
Hence, each coffee shops receives [tex]\frac{24}{6} = 4[/tex] cases of juice everyday. (Answer)
12. The equation for line G is given by
5y = -2x - 20. Suppose line G is parallel to line R, and line E is perpendicular to line G. Point (-10,8) lies on both line R and line E.
Part A: Write an equation in slope-
intercept form for line R.
Part B: Write an equation in slope-
intercept form for line E.
Answer:
Step-by-step explanation:
line G :
5y = -2x - 20...put in slope intercept form (y = mx + b)
y = -2/5x - 4....the slope(m) = -2/5
Part A.) slope intercept form for line R...since R is parallel to G, it will have the same slope....so slope(m) = -2/5
(-10,8)...x = -10 and y = 8
slope(m) = -2/5
y = mx + b
8 = -2/5(-10) + b
8 = 4 + b
8 - 4 = b
4 = b
so ur equation is : y = -2/5x + 4 <=== part A answer
since line E is perpendicular to line G, it will have a negative reciprocal slope...all that means is flip the slope and change the sign....so the slope of line E is : (flip -2/5.....-5/2.....change the sign......5/2)
(-10,8)...x = -10 and y = 8
slope(m) = 5/2
y = mx + b
8 = 5/2(-10) + b
8 = -25 + b
8 + 25 = b
33 = b
so ur equation is : y = 5/2x + 33 <== part B answer
The equation for line R is y = -2/5x + 12. The equation for line E is y = 5/2x + 33.
Explanation:Part A: To write the equation for line R in slope-intercept form, we need to find the slope and the y-intercept. Since line R is parallel to line G, it will have the same slope. The slope of line G can be determined by dividing the coefficient of x by the coefficient of y: -2/5. We can use the point-slope form, y - y1 = m(x - x1), to find the equation. Substituting the coordinates of the point (-10,8), the equation for line R is y - 8 = (-2/5)(x + 10). Simplifying, we get the equation for line R: y = -2/5x + 12.
Part B: To write the equation for line E in slope-intercept form, we need to find the slope and the y-intercept. Since line E is perpendicular to line G, its slope will be the negative reciprocal of the slope of line G. The slope of line G is -2/5, so the slope of line E will be 5/2. Using the point-slope form and substituting the coordinates of the point (-10,8), the equation for line E is y - 8 = (5/2)(x + 10). Simplifying, we get the equation for line E: y = 5/2x + 33.

Answer:
Option D. 124°
Step-by-step explanation:
step 1
Find the measure of angle AOC
The triangle AOC is an isosceles triangle, because OA=OC=radius
so
[tex]m\angle OAC=m\angle OCA=28^o[/tex]
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
[tex]m\angle OAC+m\angle OCA+m\angle AOC=180^o[/tex]
substitute the given values
[tex]28^o+28^o+m\angle AOC=180^o[/tex]
[tex]56^o+m\angle AOC=180^o[/tex]
[tex]m\angle AOC=180^o-56^o[/tex]
[tex]m\angle AOC=124^o[/tex]
step 2
Find the measure of arc AC
we know that
[tex]arc\ AC=m\angle AOC[/tex] ----> by central angle
we have
[tex]m\angle AOC=124^o[/tex]
therefore
[tex]arc\ AC=124^o[/tex]
step 3
we know that
The inscribed angle is half that of the arc comprising
[tex]m\angle ABC=\frac{1}{2}[arc\ AC][/tex]
[tex]m\angle ADC=\frac{1}{2}[arc\ AC][/tex]
so
[tex]m\angle ABC=m\angle ADC[/tex]
therefore
[tex]m\angle ABC+m\angle ADC=2m\angle ABC=arc\ AC[/tex]
substitute the value of the arc AC
[tex]m\angle ABC+m\angle ADC=124^o[/tex]

What is the most efficient way to solve the equation?
5j = 40
Answer: j = 8
Step-by-step explanation: To solve for j in this equation, we want to get j by itself on the left side of the equation. Since j is being multiplied by 5, to get j by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.
On the left side, notice that the 5's cancel out so we are simply left with j. On the right side, we have 40 divided by 5 which gives us 8 so we have j = 8.
Finally, remember to check your answer by substituting an 8 back into the original equation. So we have 5 (8) = 40 which is a true statement so our answer checks. Remember to show all your work when solving equations.
The Answer is :J=8 =)

Before beginning to answer this question, you'll need a quick formula that will be very helpful trying to answer questions like this one:
[tex]sinx^2 + cosx^2 = 1[/tex]You'll see why this formula is useful soon.
Work:
[tex]4cosx+4sinx^2=5[/tex]
The way we want to go about answering this question is very similar to what we've learned in the past: factoring. In order to be able to factor though, we need to have only [tex]cosx[/tex] in our equation instead of both [tex]sinx[/tex] and [tex]cosx[/tex] like the above equation has. this is where the formula I showed earlier comes into play.Using the equation I showed earlier, we are going to get rid of the [tex]sinx[/tex].[tex]sinx^2+cosx^2=1[/tex]
We are going to isolate [tex]sinx^2[/tex] and then substitute what its equal to into the equation.[tex]sinx^2=-cosx^2+1[/tex]
Now Substitute this back into the original equation.[tex]4cosx+4(-cosx^2+1)=5[/tex]
Put this into standard form. Then we can factor.[tex]4cosx-4cosx^2+4=5[/tex]
[tex]-4cosx^2+4cosx+4=5[/tex]
[tex]4cosx^2-4cosx-4=-5[/tex]
[tex]4cosx^2-4cosx+1=0[/tex]
Let [tex]cosx[/tex] be [tex]u[/tex].[tex]4u^2-4u+1=0[/tex]
Look familiar? We could have factored before just the same, but this ensures there will be fewer mistakes while factoring.[tex](2u-1)^2=0[/tex]
Now let's change [tex]u[/tex] back to [tex]cosx[/tex][tex](2cosx-1)^2=0[/tex]
Set [tex]2cosx-1[/tex] equal to 0.[tex]2cosx-1=0[/tex]
[tex]2cosx=1[/tex]
[tex]cosx=1/2[/tex]
Hopefully if your teacher taught you unit circle properly, you will know that [tex]cosx=1/2[/tex] is asking for an angle. In this case, I know the angle because of memorization, but sadly the only way to learn this stuff is memorization, so I wont be able to show work for how I got my final answer.

25. Algebraically determine whether the function k(x) = x6 - x2 + 7 is odd, even, or neither. Explain your
reasoning
Answer: The function is EVEN.
Step-by-step explanation:
For this exercise it is important to remember that:
1. A function f(x) is even if and only if:
[tex]f(-x) = f(x)[/tex] for all "x"
2. A function f(x) is odd if and only if:
[tex]f(-x) = -f(x)[/tex] for all "x"
So knowing that, and given the following function k(x):
[tex]k(x)=x^6 - x^2 + 7[/tex]
You can plug [tex]-x[/tex] in for "x", order to know if this is even. Then, you get:
[tex]k(-x)=(-x)^6 - (-x)^2 + 7\\\\k(-x)=x^6-x^2+7[/tex]
Therefore, since:
[tex]f(-x) = f(x)[/tex]
You can determine that that the given function [tex]k(x)=x^6 - x^2 + 7[/tex] is Even.

We can use the Pythagorean theorem to solve. (a² + b² = c²)
Fill in with what we know → 6² + b² = 11²
Simplify → 36 + b² = 121
Subtract 36 to both sides → 36 - 36 + b² = 121 - 36
Simplify → b² = 85
Take the root of both sides → √b² = √85
Simplify → b = 9.2195...
Round if necessary → 9.2195 = 9.22
Hence, b equals 9.2195.. (unrounded) or 9.22 (rounded).

Suppose an iphone loses 63% of its value each year. Write a function that represents the value of the phone after x years.
Answer:
The function which represent the phone value after x years f = i [tex](0.37)^{x}[/tex]
Step-by-step explanation:
Given as :
The rate of depreciation of i-phone value each year = r = 63%
The initial value of i-phone = $ i
The final value of i-phone = $ f
The time period for depreciation = x year
Now, According to question
The final value of i-phone = The initial value of i-phone × [tex](1-\dfrac{\textrm rate}{100})^{\textrm time}[/tex]
Or, $ f = $ i × [tex](1-\dfrac{\textrm r}{100})^{\textrm time}[/tex]
Or, $ f = $ i × [tex](1-\dfrac{\textrm 63}{100})^{\textrm x}[/tex]
Or, $ f = $ i × [tex](0.37)^{x}[/tex]
So, The function which represent the phone value after x years = f = i [tex](0.37)^{x}[/tex]
Hence, The function which represent the phone value after x years f = i [tex](0.37)^{x}[/tex] Answer
Jake owns twice as many DVDs as Louis.Bo has sixty fewer DVDs than five times Louis’s collection. If Jake and Bo have the same amount of DVDs how DVDs are in Louis’s collection?
There are 20 number of DVD's in Louis collection
Solution:
Let "J" be the number of DVD's with Jake
Let "B" be the number of DVD's with Bo
Let "L" be the number of DVD's with Louis
Given that Jake owns twice as many DVDs as Louis
So we can say,
number of DVD's with Jake = 2(number of DVD's with Loius)
J = 2L ------ eqn 1
Given that Bo has sixty fewer DVDs than five times Louis’s collection
So we can say,
number of DVD's with Bo = 5 times number of DVD's with Louis - 60
B = 5L - 60 ---- eqn 2
Given that Jake and Bo have the same amount of DVDs
number of DVD's with Jake = number of DVD's with Bo
J = B ---- eqn 3
Let us solve eqn 1, 2, 3 to find value of "L"
From eqn 1 and eqn 3,
2L = B ----- eqn 4
Substitute eqn 4 in eqn 2
2L = 5L - 60
2L - 5L = -60
-3L = -60
L = 20Thus there are 20 number of DVD's in Louis collection
Louis has 30 DVDs in his collection.
Let's denote the number of DVDs Louis has as L. According to the problem, Jake owns twice as many DVDs as Louis, so Jake has 2L DVDs. Bo has sixty fewer DVDs than five times Louis's collection, which means Bo has 5L - 60 DVDs.
Since Jake and Bo have the same amount of DVDs, we can set their quantities equal to each other:
2L = 5L - 60
Now, let's solve for L:
5L - 2L = 60
3L = 60
L = 60 / 3
L = 20
Louis has 20 DVDs in his collection.
The sum of two numbers is 33.the larger number is 3 more than two times the smaller number.what are the numbers?
Answer: 10 and 23
Step-by-step explanation:
Let the first number be x and the second number be y.
Also , let x be the bigger number and y the smaller number.
From the first statement;
x + y = 33 ............................. equation 1
From the second statement
twice the smaller number = 2y
so, if the bigger number is 3 more than two times the smaller number, this means that
x = 2y + 3 .................................... equation 2
Solving the resulting linear equations by substitution method .
substitute x = 2y + 3 into equation 1 , that is
x + y = 33 becomes :
2y + 3 + y = 33
3y + 3 = 33
3y = 30
y = 10
Substitute y = 10 into equation 2 , that is
x = 2y + 3 becomes
x = 2(10) + 3
x = 20 + 3
x = 23
Every student in the senior class is taking history or science and 85 of them are taking both. If there are 106 seniors taking history and 109 seniors taking science, how many students are in the senior class?
Number of students in senior class is 130
Solution:
Given that Every student in the senior class is taking history or science
85 of them taking both history and science
106 seniors takes history
109 seniors takes science
To find: number of students in senior class
Let A be the set of the students of the senior class that take history
Let B be the set of students of senior class that they science
The number of students in senior class is given by:
[tex]|A \cup B|=|A|+|B|-|A \cap B|[/tex]
Where,
A = 106 and B = 109 and |A n B| = 85
[tex]|A \cup B|=106+109-85=130[/tex]
Thus number of students in senior class is 130
Answer:
130
Step-by-step explanation:
Since 106 seniors are taking history and 109 seniors are taking science. If we add those numbers of seniors up we get 215, then we subtract the number of seniors that are taking both history and science because we counted them twice. So the total is 215 - 85 = 130. Therefore there are 130 students in the senior class.

So, 80 cars were in parking lot on Saturday.
(A)
Percentage of cars in parking lot on Friday is given as:
[tex]=\frac{\textrm{Cars in parking lot on Friday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{120}{200}\times 100\\\\=\frac{120}{2}=60\%[/tex]
Therefore, 60% of the cars were in the parking lot on Friday.
(B)
Now, since 60% of the cars were parked on Friday, the remaining percent will be on Saturday.
Therefore, percentage of cars in parking lot on Saturday = 100% - 60% = 40%. This can be verified with the same formula used in part (A).
[tex]=\frac{\textrm{Cars in parking lot on Saturday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{80}{200}\times 100\\\\=\frac{80}{2}=40\%[/tex]
