Using Postulates and/or Theorems, determine whether ABC~AXY.
explain why the triangles are similar or why they are not.
Answers
Answer:
They are not similar
Step-by-step explanation:
To see whether the triangles are similar or not we can compare their side lengths:
AB = 24
AX = 6
AX/AB = 1/4 is the ratio now let's compare this to AY/AC
AY/AC = 10/25 if we simplify this the result will be 2/5 as we can see the side lengths are not proportional so the triangles are not similar.

Renaldo has a
budget of $500 to buy gift boxes for a party.
Large boxes cost $65 and small boxes cost
$35. Write and graph an inequality that
represents the number of each type of gift
box that Renaldo can buy. If Renaldo buys
5 small gift boxes, how many large gift boxes
can he afford to buy?
Answers
Renal can buy a box that is $35
Step-by-step explanation:
The inequality is 35 × 5 + 65y ≤ 500. Then the number of large gift boxes will be 5.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Renaldo has a budget of $500 to buy gift boxes for a party. Large boxes cost $65 and small boxes cost $35.
Let 'x' be the number of small boxes and 'y' be the number of large boxes. Then the inequality is written as,
35x + 65y ≤ 500
If Renaldo buys 5 small gift boxes. Then the number of large gift boxes will be given as,
35 × 5 + 65y ≤ 500
175 + 65y ≤ 500
65y ≤ 325
y ≤ 5
The inequality is 35 × 5 + 65y ≤ 500. Then the number of large gift boxes will be 5.

Re-write the quadratic function below in Standard Form
y= 2(x - 2)2 – 7
Answers
Answer:
Standard form: y = 2x² - 8x + 1
Step-by-step explanation:
We are given the following quadratic function, y = 2(x - 2)² - 7, for which we must transform in its standard form.
Definition: Quadratic Function in Vertex Form:The vertex form of a quadratic function is y = a(x - h)² + k (which is the format of the given equation).
The vertex of the parabola occurs at point (h, k). The value of "a" determines the direction of the graph's opening (reflection across the x-axis); it also indicates the wideness or narrowness of the graph (vertical stretch or compression).⇒ If the value of "a" is positive, then the vertex is its minimum or lowest point on the graph.
⇒ If the value of "a" is negative, then the vertex is the maximum or highest point on the graph.
Quadratic Function in Standard Form:The standard form of a quadratic function is y = ax² + bx + c, where a ≠ 0.
Solution:Step 1: Expand the binomial, (x - 2)²:
The first step in rewriting the given equation into its standard form is expanding the binomial using the FOIL method, which transforms it into a perfect square trinomial.
y = 2(x - 2)² - 7
⇒ (x - 2)(x - 2)
⇒ [ x² - 2x - 2x + 4 ]
Step 2: Substitute the perfect square trinomial into the vertex form:y = 2(x - 2)² - 7
y = 2(x² - 2x - 2x + 4) - 7
Step 3: Distribute "2" into the parenthesis:y = 2(x² - 2x - 2x + 4) - 7
y = 2x² - 4x - 4x + 8 - 7
Step 4: Combine like terms and constants, then simplify:y = 2x² - 8x + 1.
Final Answer:Therefore, the quadratic function in standard form is y = 2x² - 8x + 1, where a = 2, b = -8, and c = 1.

Which equation matches the graph of the greatest integer function given below?
A. y= [x] + 3
B. y= [x] -3
C. y= [x] +2
D y= [x] -2
Answers
Answer:
D y= [x] -2
Step-by-step explanation:
The "floor" or "greatest integer" function graphs as a step function with a solid dot at the left end of each step. The point (0, 0) is one of those solid dots. When 2 is subtracted from the function value, the graph is shifted down 2 units so that it looks like the one given.
The given graph is of the equation ...
[tex]\boxed{y=\lfloor x\rfloor -2}[/tex]
_____
Additional comment
The ceiling function ...
[tex]y=\lceil x\rceil[/tex]
graphs as a step function with a solid dot at the right end of each step. There is a solid dot at (0, 0) for this function, as well.
Note that the function symbols have "hooks" above or below the argument to indicate ceiling or floor (respectively). The use of a square bracket [ ] for either of these functions would need to be accompanied by an explanation of the intended meaning. By itself, a square bracket has "hooks" both at the top and bottom, so does not represent either function unambiguously.

7. Arrival of the Normandy Train
Claude is waiting to meet the train from Normandy at Gare Saint-Lazare in Paris. He
tells Marie the hour of the train's arrival and he tells Jean at which minute it arrives. He
also tells them both that the train arrives between 0600 and 1000.
They consult the timetable and find the following services between those times:
0620, 0639, 0650; 0717, 0746; 0825, 0839; 0917, 0925, 0950.
Marie then says, “I don't know when Claude's train arrives, but I'm sure that neither does
Jean."
Jean replies, “I didn't know his train, but now I do."
Marie responds, “Now I do as well!"
When is Claude's train and how do you know?
Answers
Answer:
The train is 0839
Step-by-step explanation:
First off, 0620 and 0746 are not available options, as Jean would've immediately know, as they're the only one with non-repeated minutes.
Now, when Marie says "I'm sure neither does Jean", it means she didn't get 06 or 07, as those are the number that has 0620 and 0746, which then she cannot ensure that Jean doesn't know the train arrival.
We're left with 0825, 0839, 0917, 0925 and 0950
After that, Jean said he knows the train number. So, he couldnt've gotten 25, as it is repeated in the 5 options we pick. => we're left with 0839, 0917 and 0950.
And then, Marie responds now she does as well, which it cannot be 09, as it is repeated.
So, the train number is 0839.

Answers
Answers:
a) 72 km per hourb) 3 meters per secondc) 0.20 dollars or 20 cents per lemond) 50 dollars per day====================================
Explanation:
a) Divide the distance over time to get the unit rate, which is the speed in this case. Speed = distance/time = 288/4 = 72 km per hour. b) Like before, divide the distance over time to get 75/25 = 3 meters per second.c) We want the cost of 1 lemon. So we'll divide the total cost over 7 to get (1.40)/7 = 0.20 dollars = 20 cents per lemond) Divide the total cost over the 5 day period. This will get the cost of each day. So we have a unit cost of 250/5 = 50 dollars per day.Please need help with number 9 and 10!! With solution needed please!!

Answers
Speed is the ratio of distance and time
The elapsed time is 3 secondsThe average speed is 1.33 meters per secondHow to calculate the elapsed timeThe elapsed time is the difference between the final time and the initial time.
So, we have:
Time elapsed = 4.5 seconds - 1.5 seconds
Evaluate the difference
Time elapsed = 3 seconds
Hence, the elapsed time is 3 s
How to calculate the average speedThe average speed is the quotient of the distance and the elapsed time.
So, we have:
Average speed = 4 meters/ 3 seconds
Evaluate the quotient
Average speed = 1.33 meters per second
Hence, the average speed is 1.33 m/s

Vertex form: [tex]y=a(x-h)^2+k[/tex]
where (h, k) is the vertex
Rewrite function in vertex form:
[tex]\implies f(x)=(x-6)^2-36+27[/tex]
[tex]\implies f(x)=(x-6)^2-9[/tex]
Therefore, vertex = (6, -9)
As the coefficient of [tex]x^2[/tex] is positive, the parabola will open upwards (u shaped).
Point to plot:

A 2-pound package is approximately $3.50 shipping fee.
A 4-pound package is approximately $4.50 shipping fee.
The question stated, "What is the approximate difference (this means we are most likely subtracting) in cost of shipping a 2-pound and a 4 pound package(the and means we are adding both 4-pound and 2-pound together) opposed to a single 6-pound package?"
As calculated above, we should add the 2-pound package and the 4-pound package together.
3.5 + 4.5 = 8
One single 6-pound package is $5, so we need to subtract the 8 with the 5.
