Describe the sequence of transformations from quadrilateral ABCD to A'B'C'D A: -8,8 B: 8,-2 C: 4,-8 D: 4,-2 A': 2,-10 B': 8,-10 C': 2,-6 D: 8, -5?
Answers:
See below
Step-by-step explanation:
First transformation
Reflection about the line y = 6.
This inter-converted Points A and C and Points B and D.
The coordinate transformations were (Fig. 1):
A: (-8, 8) ⟶ (-8, 4)
B: (-2, 8) ⟶ (-2, 4)
C: (-8, 4) ⟶ (-8, 8)
D: (-2, 4) ⟶ (-2, 8)
Second transformation
Translation 10 units to the right and 14 units down.
The coordinate transformations were (Fig. 2):
A: (-8, 4) ⟶ (2, -10)
B: (-2, 4) ⟶ (8, -10)
C: (-8, 8) ⟶ (2, -6)
D: (-2, 8) ⟶ (8, -6)
The transformations were:
Reflection about the line y = 6 Translation 10 units to the right and 14 units downThe equation of the parabola whose focus is at (7, 0) and directrix at x = -7 is:
y = (1/28)x²
x = (1/28)y²
x = -(1/28)y²
the answer is x=(1/28)y^2
The equation of the parabola with focus at (7, 0) and directrix at x = -7 is x = (1/28)y².
The general equation of a horizontally opening parabola, using the distance between the vertex and the focus or directrix as the value of 'p'.
To find the equation of a parabola with a focus at (7, 0) and a directrix at x = -7, we first note that the vertex of the parabola is midway between the focus and the directrix. This puts the vertex at the origin (0, 0), and the parabola opens to the right since the focus is to the right of the vertex.
The general form of the equation for a parabola that opens horizontally (left or right) is
[tex](y - k)^2 = 4p(x - h)[/tex], where (h, k) is the vertex and p is the distance from the vertex to the focus.
If the parabola opens to the right (as in this case), the equation will be
[tex](y - 0)^2 = 4*(7)(x - 0)[/tex]
y² = 28x.
However, to match the format of the original options given to the student, we divide every term by 28, leading to the equation x = (1/28)y², which is the correct parabolic equation for the given focus and directrix.
If you roll two fair six-sided dice, what is the probability that the sum is 444 or higher?
Answer:
11/12
Step-by-step explanation:
Final answer:
To find the probability of rolling a sum of 444 or higher with two fair six-sided dice, calculate the sum probabilities for 444, 455, and 466, then add them together.
Explanation:
If you roll two fair six-sided dice, what is the probability that the sum is 444 or higher?
To calculate this probability, we need to first determine the total possible outcomes when rolling two dice and then find the favorable outcomes where the sum is 444 or higher.
The sum can range from 2 to 12 when rolling two dice, so we can find the probabilities for sums 444, 455, and 466, then add these probabilities up to get the final answer.

m∠H = 50°
∠H is a inscribed angle, and so that the intercepted arc would be twice the amount of the angle.
Arc KI = 100°
Because ∠KGI & ∠HKI share the same arc, the measurement for ∠KGI will be the same as ∠HKI, or 50°
m∠KGI = 50°
Next, find m∠KJI. arcKJI = 2(∠H) = 2(50) = 100
m∠KJI = 100°

Which expression is equivalent to
1/100c^3d^4
1/100c^6d^9
1/10c^3d^4
1/10c^6d^9
Answer:
1/10c^3d^4
Step-by-step explanation:
A cube root is an operation which splits expressions and numbers within it into 3 groups of the exact same size. These groups when multiplied by themselves make the expressions and numbers under the root. For example, ∛27 = 3 since 3*3*3 = 27.
Take each part under the cube root and split it into three equal groups.
1/ 1000 = 1/10 * 1/10 * 1/10 so ∛1/1000 = 1/10
c^9 = c^3*c^3*c^3 so ∛c^9 = c^3
d^12 = d^4*d^4*d^4 so ∛d^12 = d^4
Together ∛1/1000 c^9 d^12 = 1/10 * c^3 * d^4

The interest rate r required to increase your investment p to the amount a in t years is found by [tex]r=(\frac{a}{p} )^\frac{1}{t} -1[/tex]. Find the interest rate r for p = 2700, a = 6400, and t = 3. Round to the nearest hundredth.
The interest rate required to increase an investment of $2700 to $6400 in 3 years, using the formula r=(a/p)^(1/t) - 1, is approximately 38.5% per year when compounded annually.
Explanation:The subject at hand deals with the concept of finding the interest rate on an investment. The provided equation, which represents the interest rate formula, is: r=(a/p)^(1/t) - 1. Here, the variables represent the following: r is the interest rate, a is the amount of money accumulated after t years (the future value of the investment), p is the principle/original amount (the initial value of the investment), and t is the time in years. By inserting the given values (p = 2700, a = 6400, t = 3) into the formula, we get: r = (6400 / 2700)^(1 / 3) - 1.
The next step is to calculate the arithmetic for the values inside the parenthesis first, then raise it to the power of 1/3 (which is the cube root), and finally subtract 1 from the result. Doing these calculations you obtain approximately 0.385, or 38.5% when expressed as a percentage. So, the interest rate that is required to increase your investment of $2700 to $6400 in 3 years is approximately 38.5% per year when compounded annually.

How many sums????????????????? EXPLAIN!
Answer: 7
Step-by-step explanation:
The 1st spinner can land on 2, 3, 4, or 5
The 2nd spinner can land on 2 or 3
The 3rd spinner can land on 6, 7, or 8
1st spinner + 2nd spinner + 3rd spinner:
2 + 2 + 6 = 10, 2 + 2 + 7 = 11, 2 + 2 + 8 = 12 --> 3 different sums
2 + 3 + 6 = 11, 2 + 3 + 7 = 12, 2 + 3 + 8 = 13 --> 1 different sum
This pattern follows where the only new sums are as follows:
3 + 3 + 8 = 14
4 + 3 + 8 = 15
5 + 3 + 8 = 16
This makes a total of 7 different sums.

Identify the area of the rhombus.
Answer:
[tex]A=240\ m^{2}[/tex]
Step-by-step explanation:
we know that
A rhombus is a parallelogram with four congruent sides, the diagonals are perpendicular bisectors of each other
The area of a rhombus is equal to
[tex]A=\frac{1}{2}(D1*D2)[/tex]
where
D1 and D2 are the diagonals
In this problem we have
[tex]D1=16\ m[/tex]
Applying the Pythagoras Theorem find D2
[tex]17^{2} =(D2/2)^{2}+(16/2)^{2}[/tex]
[tex](D2/2)^{2}=17^{2}-(16/2)^{2}[/tex]
[tex](D2/2)^{2}=225[/tex]
[tex](D2/2)=15[/tex]

The scores on a standardized test are normally distributed with a mean of 500 and a standard deviation of 60. Jake scored 520 on the test. Find the percent of students that scored below Jake. Round your answer to the nearest whole number. (Include a step by step description of the process you used to find that percentage.)
*You will need to find the z-score using the z-score formula, the probability using the table, then change the probability to a percent.
Subtract the mean from Jake's score:
520 - 500 = 20
No divide that by the standard deviation:
20/60 = 0.33
This means Jake scored 0.33 standard deviations above the mean.
Now using the Z-table find 0.33: 0.33 = 0.6293 = 62.93% of students scored below Jake.
Rounded to nearest whole number = 63%
Answer:
63% of students
Step-by-step explanation:
Z = (X - μ) / σ
Z = 520 - 500 / 60
Z = 0.33
ON THE Z-TABLE
0.33 = 0.6293
62.93% = 63% of students answer
A duplex generates $1,400 rent for each of its two units per month. The property has been recently appraised for $350,000. What is this property's GIM? 4.8, 9.6, 10.4, or 20.83??
Answer:
10.4
Step-by-step explanation:
To get the property's gross income multiplier (GIM), you divide its appraised value by its gross annual rental income.
Rental income = 2 × $1400/1 month × (12 months/1 yr)
= $33 600/yr
GIM = $350 000/$33 600 = 10.4
The property's GIM is 10.4.

A car travels at an average speed of 48 miles per hour. How long does it take to travel 180 miles?
Answer:
3 hours and 45 minutes
Step-by-step explanation:
The time to travel 180 miles at an average speed of 48 miles per hour is approximately 3.75 hours. This was calculated using the formula Time = Distance / Speed.
Explanation:The question is based on time, speed, and distance, all correlating with each other, and to solve, we will use the following frequently used formula:
Time = Distance / Speed
We can substitute the given values into our formula. We know our distance is 180 miles and our speed is 48 miles per hour. So, our equation becomes:
Time = 180 miles / 48 miles per hour
