The intersection of the two planes is a Line.
According to the statement
We have to find that the Intersection of the planes.
So, For this purpose, we know that the
An intersection is a single point where two lines meet or cross each other.
From the given information:
A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors.
And then the intersection of the plane becomes:
Then
The intersection of two planes is a line. If the planes do not intersect, they are parallel.
They cannot intersect at only one point because planes are infinite.it means parallel planes have no intersection point.
So, The intersection of the two planes is a Line.

A reflection followed by rotation
B. translation followed by rotation
C. translation followed by reflection
reflection followed by translation
D.
The drawing shows a series of transformations and the sequence that moves Triangle I to Triangle II to Triangle III is translation followed by reflection.
A reflection in arithmetic is a form of geometrical transformation, wherein an item is flipped to create a reflect or congruent image. The bisector of the plane is referred to as the definition on the line of reflection, and it is perpendicular to the preimage and photograph.
In the coordinate plane we will draw the translation if we recognize the path and how far the figure have to be moved. To translate the factor P(x,y) , a units right and b units up, use P'(x+a,y+b) .
A translation is a form of transformation that takes every factor in a figure and slides it the equal distance in the equal path.
Here, the image is first translated and then rotated.
Therefore, the drawing shows a series of transformations and the sequence that moves Triangle I to Triangle II to Triangle III is translation followed by reflection.

An employee at Kennedy Space Center (KSC) lives in Daytona Beach and works in the vehicle assembly building (VAB). She
carpools to work with a colleague. She drives 7 miles from her house to the park-and-ride. Then she rides with her colleague from the
park-and-ride in Daytona Beach to the KSC headquarters building, and then takes the KSC shuttle from the headquarters building to
the VAB. The drive from the park-and-ride to the headquarters building is of her total trip, and the shuttle ride is of her total trip.
How many miles does she travel from her house to the VAB on days her colleague drives?
Using proportions, it is found that she travels 60 miles from her house to the VAB on days her colleague drives.
What is the missing information?The drive from the park-and-ride to the headquarters is 5/6 of her trip.The shuttle ride is 1/20 of her trip.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The first step is finding the fraction corresponding to the 7 miles, hence considering that the total is of 100% = 1 and the fractions given above, we have that:
1 - 5/6 - 1/20 = 1 - 0.8333 - 0.05 = 0.1167.
The 7 miles represent 0.1167 of the trip, hence:
0.1167x = 7
x = 7/0.1167
x = 60.

Tia climbed to the top of an observation tower overlooking a bird sanctuary and used the telescope at the top to observe two nests. The first nest was 400 meters away from the observation tower. Tia turned the telescope 135 degrees to observe the second nest, which was 300 meters away. How far apart are the two nests?
Answer:
648 m
Step-by-step explanation:
Given observations of two nests, one at 400 m, and the other at 300 m in a direction 135° from the first, you want to know the distance between the nests.
Law of CosinesThe law of cosines can be used to find the third side of a triangle, given two sides and the angle between them. It tells us ...
c² = a² +b² -2ab·cos(C)
In this scenario, we have a=400, b=300, and C=135°. The distance c is then ...
c² = 400² +300² -2·400·300·cos(135°) ≈ 419,705.63
c ≈ √419,705.63 ≈ 647.8
The two nests are about 648 meters apart.

Riley has $200.00. She spends $60.00 on a video game.
What percent of her money does Riley spend? Draw a diagram to show your thinking.
Answer:
Step-by-step explanation:
you buy x packs of pencils, twice as many packs of erasers, and three times as many rolls of tape. write an expression in simplest form for the total amount spent.
pencils cost 1.85
erasers cost 3.15
tape cost 2.50
Items purchased:
x packs of pencils,
twice as many packs of erasers, total number of eraser packs = 2x
three times the number of tape rolls, number of tape rolls = 3x
total expenditure = x m + 2xn + 3xp = x(m + 2n + 3p)
We now have two possibilities:
1- All three goods are the same price:
cost of one pencil pack = cost of one eraser pack = cost of one roll of tape = m
x m + 2xm + 3xm = 6xm
total amount spent
2- The three goods are not the same price:
m = the cost of one pencil pack
n = the cost of one pack of erasers
One roll of tape costs p.
total expenditure = x m + 2xn + 3xp = x(m + 2n + 3p)

toward Atlanta at an average rate of 60 mph. Pat leaves Atlanta at the same time, driving toward Cincinnati in her antique auto, averaging 28 mph. How long will it take them to meet?
Answer:
5 hours
Step-by-step explanation:
28x = 60(440-x)
28x = 60*440 - 60x
88x = 60*440
x = 60*440/88
x = 300mi, distance Jon travels
300mi/60mph = 5hrs, the time it took them to meet

60MPH*5HR + 28MPH*5HR = 300MI + 140MI = 440MI
Function yes or no what is the domain and range
Step-by-step explanation:
I assume the grid units are single units (1, 2, 3, ...).
to be a function every value of x must have exactly one value of y.
but that is violated at x = 2. at that point y can be either +3 or -3 (indicated by the 2 points at x=2).
so, no, it is not a function.
the domain is the interval or set of all valid x (input) values.
since we have no continuous curve but single points, it is a set :
x € {-4, -3, -2, 1, 2, 3, 6}
the range is the interval or set of all valid y (function result) values. again, it is a set for the same reasons :
y € {-3, -2, 0, 1, 3, 4}
You know the sum of -5 and another integer is a positive integer. What can you conclude about the sign of the other integer? What can you conclude about the value of the other integer. Explain.
The sign of the other integer is positive. Value of other integer is greater than 5.
When we add two numbers of the same sign, final number has the same sign of the initial numbers
For example, we add 3 and 8,
3+8= 11
Both the numbers 3 and 8 are positive so our result is also positive.
On the other hand when we add -3 and -8, then the result will be
-3 +(-8)= -11
Both the numbers are negative, so our result also negative.
When two numbers of different sign are being added then the sign of the larger number decide the sign of the final number
For example, we add -3 and 8.
-3+8= 5
8 is larger than 3, and has positive sign, so the result will also be positive.
Suppose other number is x.
-5+x>0 (As the sum is positive)
Add 5 on both the sides
-5+x+5>0+5
x>5
As we can see the number is greater than 5 and has a positive value.
Final answer: The sign of the other integer is positive. Value of other integer is greater than 5.

The fluid force against the window is equal to 931.5 lb.
Given the following data:
Width of viewing portion = 69 inches.Dimension of fish tank = 69 × 28.5 × 1.5 inches.Density of seawater = 64 lb/ft. Thickness of glass = 3/4 inch.How to calculate the fluid force against the window?Generally speaking, the fluid force that is exerted on the fish tank by the seawater is due to the liquid pressure acting over the given area. Also, the fluid force that is exerted on the fish tank is directly proportional to the depth of seawater.
The depth of seawater is given by:
Depth = 28.5 - 1.5
Depth = 27 inches.
Next, we would convert the unit of the depth of seawater and width of viewing portion in inches to feet:
1 inch = 12 feet
Depth = 27 inches to feet = 27/12 = 2.25 feet.
Width = 69/12 = 5.75 feet.
Now, we can calculate the fluid force against the window by using this formula:
Fluid force = (density × depth × width)/2
Fluid force = (64 × 2.25² × 5.75)/2
Fluid force = 1863/2
Fluid force = 931.5 lb.

Answer:
see explanation
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width )
using the property [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a , then
A = 2[tex]\sqrt{7}[/tex] × 10[tex]\sqrt{7}[/tex]
= 2 × 10 × [tex]\sqrt{7}[/tex] × [tex]\sqrt{7}[/tex]
= 20 × 7
= 140 ft²

the perimeter (P) is calculated as
P = 2(l + w)
= 2(2[tex]\sqrt{7}[/tex] + 10[tex]\sqrt{7}[/tex] )
= 2(12[tex]\sqrt{7}[/tex] )
