If f(x) = x
What is g(x) if the graph moves 9 units up and 2 units to the right
Shift 2 units left: y = [tex](x+2)^{2}[/tex]
shift up 9 units: y = [tex](x+2)^{2}[/tex] + 9
reflect in the x-axis: y = - [tex](x+2)^{2}[/tex] - 9
y =[tex]x^{2}[/tex]
Shift 2 units left: y = [tex](x+2)^{2}[/tex]
Then, shift up 9 units: y = [tex](x+2)^{2}[/tex] + 9
Then, reflect in the x-axis: y = - [tex](x+2)^{2}[/tex] - 9
Each reference coordinate line is referred to as an axis of the system, or simply an axis (plural axes), and its origin is at the ordered pair intersection (0, 0). The positions of the perpendicular projections of the point onto the two axes, represented as signed distances from the origin, can likewise be used to establish the coordinates.
The same idea may be used to determine the location of any point in three dimensions using three Cartesian coordinates.

is it true that two pairs of adjacent sides of a kite are equal
Yes , it is true that two pairs of adjacent sides of a kite are equal .
A kite is a quadrilateral with two pairs of equal adjacent sides. The angles between adjacent pairs of sides are equal. The kite shape is a rectangle with two pairs of adjacent sides of equal length. The side pairs of the kite are not parallel, but the diagonal pairs are equal.If two sides share a common angle, then they are called adjacent sides.A quadrilateral with two pairs of adjacent sides equal in length is called a kite. Kites also have one pair of opposite angle equal as shown in the figure below.

was the maximum number of people that could be helped with one plane of supplies?
Using a system of equations, it is found that the maximum number of people that could be helped with one plane of supplies is: 40,000.
What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
For this problem, the variables are given as follows, considering the situation described:
Variable x: number of food kits sent.Variable y: number of medicine kits sent.Each food kit helped 8 people and each medicine kit helped 6 people, hence the total number of people helped is given by:
T = 8x + 6y.
This is because we consider that people were helped by only one of them, never both.
Each plane could carry no more than 80,000 pounds. Each food kit weighed 20 pounds and each medicine kit weighed 10 pounds, hence:
20x + 10y = 80000
2x + y = 8000
y = 8000 - 2x.
The maximum volume is of 6000 cubic feet, hence:
x + y = 6000.
y = 6000 - x.
Equaling both equations:
8000 - 2x = 6000 - x
x = 2000.
y = 6000 - x = 4000.
Then the maximum number of people helped is:
T = 8x + 6y = 8 x 2000 + 6 x 4000 = 40,000.

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:

Now, we have that
QR = 18 units
PR = 5 x + 6
We have to sind the value of x.
Substituting the values of PR and QR in the equation, we get that:
5 x + 6 = 18
5 x = 18 - 6
5 x = 12
x = 12 / 5
x = 2.4 units
Therefore, we get the value of x as 2.4 units when QR is 18 units.

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:

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

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

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.
