The trapezoid A’B’C’D is a dilation of the trapezoid ABCD. What is the scale factor of the dilation?
Simplify your answer and write it as a proper fraction, an improper fraction, or a whole number.
PLEASE LOOK AT PICTURE!!!!!!
All corresponding side lengths have a ratio of [tex]\frac{1}{3}$[/tex] or less, we can conclude that the scale factor of the dilation is less than or equal to [tex]\frac{1}{3}$[/tex]
How to find factor of dilation?We can use the distance formula to find the length of the sides of both quadrilaterals, and then find the ratio of corresponding side lengths to determine the scale factor of the dilation.
Let's start with the original quadrilateral ABCD. The length of AB is:
[tex]$\sqrt{(9 - (-3))^2 + (3 - 0)^2} = \sqrt{12^2 + 3^2} = \sqrt{153}$[/tex]
Similarly, the lengths of BC, CD, and DA are:
[tex]BC: $\sqrt{(9 - 9)^2 + (9 - 3)^2} = 6$[/tex]
[tex]CD: $\sqrt{(-3 - 9)^2 + (3 - 9)^2} = \sqrt{144 + 36} = \sqrt{180} = 6\sqrt{5}$[/tex]
[tex]DA: $\sqrt{(-3 - (-3))^2 + (3 - 0)^2} = 3$[/tex]
Now, let's find the corresponding side lengths of the dilated quadrilateral A'B'C'D'. The length of A'B' is:
[tex]$\sqrt{(3 - (-1))^2 + (1 - 0)^2} = \sqrt{16 + 1} = \sqrt{17}$[/tex]
Similarly, the lengths of B'C', C'D', and D'A' are:
[tex]B'C': $\sqrt{(3 - 3)^2 + (3 - 1)^2} = 2$[/tex]
[tex]C'D': $\sqrt{(-1 - 3)^2 + (1 - 3)^2} = \sqrt{16 + 4} = \sqrt{20} = 2\sqrt{5}$[/tex]
[tex]D'A': $\sqrt{(-1 - (-3))^2 + (1 - 0)^2} = \sqrt{4 + 1} = \sqrt{5}$[/tex]
Now we can find the ratio of corresponding side lengths:
[tex]$\frac{\text{length of A'B'}}{\text{length of AB}} = \frac{\sqrt{17}}{\sqrt{153}} = \frac{\sqrt{17} \cdot \sqrt{153}}{153} \approx 0.821$[/tex]
[tex]$\frac{\text{length of B'C'}}{\text{length of BC}} = \frac{2}{6} = \frac{1}{3}$[/tex]
[tex]$\frac{\text{length of C'D'}}{\text{length of CD}} = \frac{2\sqrt{5}}{6\sqrt{5}} = \frac{1}{3}$[/tex]
[tex]$\frac{\text{length of D'A'}}{\text{length of DA}} = \frac{\sqrt{5}}{3}$[/tex]
Since all corresponding side lengths have a ratio of [tex]\frac{1}{3}$[/tex] or less, we can conclude that the scale factor of the dilation is less than or equal to [tex]\frac{1}{3}$[/tex]. To find the exact scale factor, we can choose any two corresponding side lengths and take their ratio.

if you borrow $1,000 for 4 years at an annual interest rate of 8% what is e total amount of money you will pay back
The total amount of money you will pay back when borrowing $1,000 for 4 years at an annual interest rate of 8% with annual compounding is $1,360.50.
How does compound interest work?The interest you receive is referred to as compound interest. Using simple math, you can see how this works: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year.
According to the given information:A = P*(1 + r/n)[tex]^(^n^*^t^)[/tex]
A is the total amount
P is the principal (initial amount borrowed), which is $1,000 in this case
r is the annual interest rate expressed as a decimal, which is 0.08 (8%)
n is the number of times the interest is compounded per year, which is usually 12 (monthly compounding) or 1 (annual compounding)
t is the time in years, which is 4 in this case
Assuming that the interest is compounded annually (n=1), we can plug in the values and simplify:
A = 1000*(1 + 0.08/1)¹⁴
= 1000(1.08)⁴
= 1000*1.3605
= $1,360.50
the total amount of money you will pay back when borrowing $1,000 for 4 years at an annual interest rate of 8% with annual compounding is $1,360.50.

D.5√∠(63.4°)
1 + 2i in polar form is 5√2∠63.4°.
What is a polar form ?
In mathematics, the polar form is a way of representing complex numbers using their magnitude and angle. A complex number can be represented in the form r(cos θ + i sin θ), where r is the magnitude (or modulus) of the complex number, and θ is its argument (or phase angle). Alternatively, the polar form can be represented in terms of magnitude and angle as r ∠θ, where r is the magnitude and θ is the angle in radians. This form is also known as the exponential form of a complex number. The polar form is useful in calculations involving complex numbers, especially in multiplication and division, where it is often easier to work with the polar form rather than the rectangular form (a + bi).
D. 5√2∠63.4°
To convert a complex number from rectangular form to polar form, we use the following formulas:
r = √(a^2 + b^2)
θ = tan^-1 (b/a)
Where a and b are the real and imaginary parts of the complex number, respectively.
In this case, a = 1 and b = 2, so:
r = √(1^2 + 2^2) = √5
θ = tan^-1 (2/1) = 63.4°
Therefore, 1 + 2i in polar form is 5√2∠63.4°.

How many feet does Ava walk in one second
Ava walks 2.5 feet in one second.
How do we calculate?Ava walks 5 feet in 2 seconds, which means that the ratio of feet to seconds is 5 to 2.
We will use proportionality concept , to find out how many feet Ava walks in one second,
Let x be the number of feet Ava walks in one second. Then we can set up the proportion:
5 feet / 2 seconds = x feet / 1 second
solving for x, we can cross-multiply:
5 feet * 1 second = 2 seconds * x feet
Simplifying, we get:
5 feet = 2x feet
Dividing both sides by 2, we get:
x = 2.5 feet
In conclusion, Ava walks 2.5 feet in one second.

type of measurement enables learners to quantify the measurement of an object, but differs in amount each time.
Answer:
variable measurement
Step-by-step explanation:
The type of measurement you are referring to is called "variable measurement". In variable measurement, the quantity being measured can vary from one observation to another. This means that the measurement is not consistent or fixed, and can change each time it is taken. An example of variable measurement is measuring the weight of a person over time, as their weight can change from one day to another. Another example is measuring the temperature in a room throughout the day, as the temperature can fluctuate based on factors such as sunlight, air conditioning, and human activity.
the front of a tent has the shape of an isosceles triangle with equal sides of 163 cm long. the measure of the angle at the peak of the tent is 103 degrees. determine the height of the tent to the nearest centimetre.
To find the height of the tent, we need to use trigonometry. Let's draw a diagram to help visualize the problem
/|\
/ | \
h / | \ h
/ | \
/ | \
/ | \
/ | \
/_ _|_ __\
b 81.5 b
We can see that the height of the tent (h) forms one leg of a right triangle, with the base (b) being half of one of the equal sides of the isosceles triangle. We can use the angle at the peak of the tent (103 degrees) to find the height using the tangent function:
tan(103) = h/b
To find b, we can use the fact that the equal sides of the isosceles triangle are 163 cm long, so b = 163/2 = 81.5 cm.
Now we can plug in b and the angle measure into the tangent equation and solve for h:
tan(103) = h/81.5
h = 81.5 * tan(103)
h ≈ 370.5 cm
Therefore, the height of the tent is approximately 370.5 cm or 371 cm to the nearest centimeter.

The measure of an angle is twice less than that of its supplement angle.
The supplementary angle will be 60°.
What are supplementary angles?
Supplementary angles are angles (only two) whose sum is equal to 180 degrees. In other words, if we add two angles together and the result is 180 degrees, those angles are considered supplementary.
For example, if we have angle A that measures 60 degrees, its supplement angle B will measure 120 degrees (180 - 60 = 120). Angles A and B are supplementary angles.
Supplementary angles can be adjacent, meaning they share a common vertex and side, or they can be non-adjacent. In either case, their sum will always be 180 degrees.
Supplementary angles are commonly used in geometry and trigonometry to solve problems related to angles and triangles.
Now,
Let x = measure of the angle.
Then, the supplement angle is 180 - x.
According to the problem, x is twice less than the supplement angle. In other words, the supplement angle is twice greater than x. We can write this as:
180 - x = 2x
Solving for x, we get:
180 = 3x
x = 60
Therefore, the angle measures 60 degrees.

The circle below is divided into six equal pieces. If the area of the shaded region is 98pi what is the
circumference of the circle? Leave answer in terms of pi
Consequently, the circle's diameter is 28π√3.
What is its the circumference?The radius of a circular or other curved geometry form refers to its length. It is the border across any two-dimensional circle surface measured linearly in one dimension.
Since the circle is divided into six equal pieces, the shaded region represents one-sixth of the total area of the circle. Therefore, the total area of the circle can be found by multiplying the shaded area by 6:
Total area of circle = 6 × 98π = 588π
The formula for the area of a circle is A = πr², where r is the radius of the circle. Solving for r, we get:
r² = A / π = 588π / π = 588
r = √588 = 2√147 = 2√3 × √49 = 14√3
C = 2r is the method for calculating a circle's diameter. Plugging in the value of r, we get:
C = 2π(14√3) = 28π√3
Therefore, the circumference of the circle is 28π√3.

Angela, Breanna, Christine, Debbie, and Esther are in a club and they need to pick two people to go to a
meeting. They write each person’s name on equally sized pieces of paper, put them in a hat, and mix the
papers thoroughly. Find the probability model for this chance process and use it to determine the probability
that Angela gets to go to the meeting.
The probability that Angela gets to go to the meeting is 2/5 or 0.4.
What is probability?
There are a total of 5 people in the club, and they need to pick 2 people to go to the meeting. The number of ways to pick 2 people out of 5 is given by the binomial coefficient:
C(5,2) = 5! / (2! (5-2)!) = 10
This means there are 10 equally likely outcomes, which can be represented by the following probability model:
Outcome Angela goes to meeting? Probability
A,B Yes 1/10
A,C Yes 1/10
A,D Yes 1/10
A,E Yes 1/10

B,D No 1/10
B,E No 1/10
C,D No 1/10
C,E No 1/10
D,E No 1/10
The probability that Angela gets to go to the meeting is the sum of the probabilities of the outcomes where Angela goes to the meeting:
P(Angela goes to meeting) = P(A,B) + P(A,C) + P(A,D) + P(A,E)
= 1/10 + 1/10 + 1/10 + 1/10

Therefore the probability of drawing a ball with a number less than 20 is 0.38 or 38%.
How to find the probability ?Probability is a measure of an event's likelihood or chance of occurring. It is usually expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is unavoidable.
The probability of drawing a ball with a number less than 20 is calculated by dividing the total number of balls by the number of balls less than 20.
There are 19 balls numbered 1 through 19. As a result, the likelihood of drawing a ball with a number less than 20 is:
P(less than 20) = total number of balls / total number of balls = 19 / 50 = 0.38

is initially 2 cm to the right of 0.
The formula for the displacement function (t).= s(t) = t - t^2 = 2 cm
Find the total distance travelled in the first second of motion.
answer = 1/2 cm but unsure how to solve
Please show procedure
Answer:
Step-by-step explanation:
To find the total distance traveled in the first second, we need to find the distance traveled during the first half-second and then double it.
The particle starts 2 cm to the right of 0, so its position function is given by:
s(t) = t - t^2 + 2
The distance traveled by the particle during the first half-second (from t = 0 to t = 0.5) is given by:
distance = |s(0.5) - s(0)|
We have:
s(0.5) = 0.5 - (0.5)^2 + 2 = 2.25 cm
s(0) = 0 - 0^2 + 2 = 2 cm
So, the distance traveled during the first half-second is:
|2.25 - 2| = 0.25 cm
To find the total distance traveled in the first second, we double this distance:
total distance = 2 * 0.25 = 0.5 cm
Therefore, the total distance traveled in the first second is 0.5 cm.
