Describe a sequence of translations, rotations, and
reflections that takes polygon P to polygon Q.
Use the digital tracing paper if it helps you with your
thinking?
The polygon P is translated and rotated respectively to obtain polygon Q.
A translation is a geometric transformation when each point in a figure, shape, or space is moved in a specific direction by the same amount. A translation can also be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.
Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.
ABCD and EFGH are polygons P and Q respectively.
We will briefly outline each step required to convert each Polygon P into its corresponding Polygon Q in this question.
In this case, there is translation along a vector between point A and point H.
Then, when the polygon Q is rotated around point H.

What is the length of the hypotenuse of a 45°-45°-90° triangle if the leg length is 6 centimeters?
The length of the hypotenuse of a 45°-45°- 90° triangle with a leg length of 6 centimeters is 8.49 approximately.
To find the hypotenuse of 45°-45°-90° triangle:
The formula to calculate the hypotenuse of 45°-45°-90° triangle is to multiply the length of the leg by [tex]\sqrt{2}[/tex].
How to find the length of the hypotenuse?
The length of the two legs of 45°-45°-90° triangle is equal.
Then the length of its hypotenuse will be calculated by multiplying the length of the leg and [tex]\sqrt{2}[/tex] .
Since the length of the leg is 6 centimeters,
Then its hypotenuse will be:
h = 6 × [tex]\sqrt{2}[/tex]
h = 8.485
h ≈ 8.49
So, the length of the hypotenuse will be 8.49.

Answer:
Step-by-step explanatio -3/8d-1 3/8
The expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or (-3 1/4d + 3/5) - (2 7/8d + 7/10) is equivalent to "negative forty nine over 8 times d minus one tenth" or -49/8d - 1/10.
An algebraic expression is a number, variable, or the combination of both and operational symbols.
To determine the equivalent of the expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or simply (-3 1/4d + 3/5) - (2 7/8d + 7/10), combine all like terms and perform the necessary operations.
(-3 1/4d + 3/5) - (2 7/8d + 7/10)
⇒ -3 1/4d + 3/5 - 2 7/8d - 7/10
⇒ (-3 1/4 - 2 7/8)d + 3/5 - 7/10
⇒ (-13/4 - 23/8)d + 6/10 - 7/10
⇒ (-26/8 - 23/8)d - 1/10
⇒ -49/8 d - 1/10
Hence, the equivalent expression is "negative forty nine over 8 times d minus one tenth" or -49/8d - 1/10.

Given two terms of each arithmetic sequence, find a₁ and d .a₄=-2.4 and a₆ = 2
The common difference d is 2.2 and the first term a1 is -9.
How to find the a1 and d?The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same value.
The formula of Arithmetic progression is
a(n) = a1 + (n - 1)d
given that the two terms of arithmetic sequence,
a4 = -2.4 and a6 = 2.
now, find the common difference d.
a(n) = a1 + (n - 1)d
Let take a(n) = a6 and a1 = a4.
a6 = a4 + (6 - 4)d
a6 = a4 + 2d
now substitute the values of a6 and a4
2 = -2.4 + 2d
2 + 2.4 = 2d
d = 4.4/2
d = 2.2
so, the common difference d is 2.2.
then, find the term a1.
take the formula
a(n) = a1 + (n - 1)d
now, substitute a(n) = a4 and d = 2.2.
-2.4 = a1 + (4-1)d
-2.4 = a1 + 3d
-2.4 = a1 + 3(2.2)
-2.4 = a1 + 6.6
a1 = -6.6-2.4
a1 = -9.
so, the first term a1 is -9.
Hence, the common difference d is 2.2 and the first term a1 is -9.

Step-by-step explanation:
a)
high positive x (x going to +infinity) would create high positive y (also +infinity).
while high negative x (x going to -infinity) would create high negative y (also -infinity), x⁵ with its odd exponent is negative for negative x and positive for positive x.
the graph is showing just the opposite behavior.
so, it cannot be the right graph.
b)
the degree of the polynomial is the highest exponent of the input variable x. in our case : 5
a polynomial of degree n must have n zeros (or roots).
in our case we need 5 zeros. but there are only 3. no matter how we shift it up or down, the x-axis will not intercept it more than 3 times.
so it cannot be the right graph.

What makes up the total cost for membership for m months?
The fact that each member has to pay an enrollment fee and purchase key card for $79.95 and $19.95 respectively, means that the total fixed charge which is sum of both amounts is computed as shown below:
fixed charge=$79.95+$19.95

COORDINATE GEOMETRY Find the distance from P to l .Line l contains points (0,-2) and (1,3) . Point P has coordinates (-4,4) .
According to the given statement the perpendicular distance form the point (-4,4) is 66.3.
What Exactly Is Coordinate Geometry?Coordinate Geometry can be used to define points in space. The primary axis labeled a x- and y-axes is defined first, and then the points were measured and labelled in relation to these points. Furthermore, numerous geometric forms such as a line, curve, circle, ellipse, and hyperbola can be plotted inside the coordinate axes and their attributes studied.
According to the given data:the equation for line ℓ.
Begin by finding the slope of the line through the given points,(0,-2) and (1,3):
m = (Y₂ - Y₁)/(x₂ - x₁)
= (3 - (-2))/(1 - 0)
= 5/1
= 5
The equation of the line using point (1,3) on the line:
Y - Y₁ = m(x - x₁)
putting value we get: (m = 5)
Y - (-2) = 5(x - 1)
Y + 2 = 5x - 5
Y = 5x - 3
The equation of the line w perpendicular to line ℓ through P(-4,4).
The slop of line l is 5. Write the equation of the line using point P(-4,4) on the line.
Y - Y₁ = m(x - x₁)
Y - 4 = 5(x - (-4))
Y - 4 = 5x + 4
Y = 5x + 8
Solve the system of equations to determine the point of intersection. Subtract both sides of (1) and (2) to eliminate y.
5x + 8 = 5x - 3
5x + 8 - 5x + 3 = 0
x = 11
putting the value of x to find y:
Y = 5x + 8
Y = 62
Applying the formula to find the distance of a points:'
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
d = √((11 - 4 )² + (62 + 4)²)
d = √(4405)
d = 66.3
According to the given statement the perpendicular distance form the point (-4,4) is 66.3.

What is the volume of the cuboid?The volume of a cuboid is equal to the product of the length, width, and height of a cuboid.
The volume of a cuboid is length × breadth× height
As it is 3D geometry
The volume will be L×W×H i.e. 50×25×2 = 2500 m³
Since one cubic meter is equal to 264.172052 gallons,
So 2500 m³ = 264.17 × 2500 = 660425 gallons
If the water bill is equivalent to $1 per 1000 gallons

The size of the segment in the scale drawing using a drawing scale factor of 5 meters to one box is 30 meters.
What are scale factors?A scale factor is a value with which the dimensions of an original two dimensional geometric figure or a three dimensional solid can be multiplied to obtain an image.
Scale factors are used in maps and drawings to represent a large geographic area, or a life sized object on paper, such that the relative sizes of the sides of the original figure are maintained
Solution;
Using the height of the arc in the drawing as the reference, we have;
50 m is equivalent to 10 boxes
Therefore;
The length of one box = (50 m)/10 = 5 m
The scale of the drawing is therefore;
One box = 5 metersThe length of the given segment = 6 box length
