A hotel chain charges $75 each night for the first two nights and $50 for each additional night’s stay. the total cost t is a function of the number of nights x that a guest stays.
you would need a function to determine whether to use a formula for 1 or 2 nights or a formula for more than 2 nights
T(x)={a if x <_ 2, b if x > 2}
if it's 2 nights or less use option a, a = 75x
if its longer than 2 days use option b, b= 50x + 50
Answer:
t = 75x {x ≤ 2}
t = 150 + 50x {x > 2}
Step-by-step explanation:
A hotel chain charges $75 per night for first two nights.
If the number of nights of the stay are x then charges for x nights
= 75x where x ≤ 2
If the stay is for than 2 nights then charges for x nights
= Charges for two first 2 nights(@$75 per night) + charges for other than initial 2 nights (@$50 per night)
= (75×2) + 50x where x > 2
Therefore total cost of the hotel if represented by t then the function will be
t = 75x {x ≤ 2}
t = 150 + 50x {x > 2}

A regular hexagon and an equilateral triangle have equal perimeters. what is the ratio of the area of the hexagon to the area of the triangle? express your answer as a common fraction.
The measures of an exterior angle and the adjacent interior angle add up to 360 because they form a linear pair
A.True
B.False
Answer: false
Step-by-step explanation:
Let $abcd$ be a parallelogram. extend $\overline{bc}$ past $b$ to $f$, and let $e$ be the intersection of $\overline{ab}$ and $\overline{df}$. if the areas of triangles $bef$ and $ade$ are 1 and 9, respectively, find the area of parallelogram $abcd$.
Triangles ade and bef are similar due to equal angles. The ratio of their areas (9:1) means their sides have a ratio of 3:1. Using the properties of parallelograms, the parallelogram's area will be double the area of triangle ade, or 18 square units.
Explanation:In the given problem, we have a parallelogram abcd and we're asked to find its area. Given the properties of a parallelogram, we know that angle bad equals angle bef. This leads to the conclusion that triangle ade is similar to triangle bef since their angles are the same. As the ratio of their areas is 9:1, it's clear the ratio of their sides is 3:1, since the ratio of the areas of similar figures is the square of the ratio of their corresponding sides.
The parallelogram's area will be double the area of triangle ade, thanks to the properties of a parallelogram (it's made up of two congruent triangles). Therefore, the area of the parallelogram is 18 square units. The important steps here were recognizing the similar triangles and knowing how to calculate a parallelogram's area.

y = (x + 3)2 − 2
y = (x − 3)2 − 2
y = (x + 3)2 + 2
y = (x − 3)2 + 2
Answer:
The correct answer is [tex]y = \frac{10}{9}(x+3)^2+2[/tex]
Step-by-step explanation:
The correct answer to the question is not provided in the options listed below.
In order to find the equation of the quadratic function that you're looking for, you should identify the two points the parabola passes through: the vertex (that is point (-3,2)) and the y-intercept (the point (0,12)).
As we are given the vertex of the quadratic function, we can use the completed square form: [tex]y=a(x-h)^2+k[/tex], where h and k are, respectively, the x and y coordinates of the vertex.
As (-3,2) is the vertex, we have:
[tex]y=a(x+3)^2+2[/tex]
Now, as the graph passes through the point (0,12), we can replace x=0 and y=12 in the formula above in order to find the value of a. Then, we make a the subject of the equation:
[tex]12=a(0+3)^2+2[/tex]
[tex]12=9a+2[/tex]
[tex] 10=9a[/tex]
[tex] \frac{10}{9}=a[/tex]
So, the equation of the parabola is [tex]y=\frac{10}{9}(x+3)^2+2[/tex].
How to find 0.36 repeating in a equivalent fraction form?
To convert 0.36 repeating into a fraction, we get [tex]\frac{4}{11}[/tex].
To convert the repeating decimal 0.36 repeating (written as 0.363636...) into a fraction, follow these steps:
Let x = 0.363636...Multiply both sides of the equation by 100 (since the repeating part is two digits long):⇒ 100x = 36.363636...
Subtract the original equation from this new equation:⇒ 100x - x = 36.363636... - 0.363636...
⇒ 99x = 36
Solve for x:⇒ x = [tex]\frac{36}{99}[/tex]
Simplify the fraction by finding the greatest common divisor (GCD) of 36 and 99, which is 9:⇒ x = ([tex]\frac{36}{99}[/tex]) / ([tex]\frac{99}{9}[/tex]) = [tex]\frac{4}{11}[/tex]
Therefore, the fraction equivalent of 0.36 repeating is [tex]\frac{4}{11}[/tex].

the first term of the sequence is 13 the term to rule is take away -5 work out the 4th term
The student is trying to find the 4th term in a mathematical sequence where the first term is 13 and the rule for each term is to add 5. Thus, the 4th term of this sequence is 28.
Explanation:The student is asking about a mathematical sequence where the first term is 13 and the term to rule is 'take away -5', or in other words, add 5 (since subtracting a negative number is the same as addition). So, to find the nth term of this sequence, you subtract (or add in this case) -5 to the first term, and continue in the sequent term.

How much more would the value of y be on the graph than its value in the table when x = 12?
20
30
60
70
For the table, y = 25x.
When x = 12, y = 25*12 = 300
For the graph, y = 30x
When x = 12, y = 30*12 = 360
When x = 12, the value of y on the graph is 60 more than its value in the table.
Answer:
The correct option is C. The value of y be on the graph than is 60 more than the y value in the table when x = 12.
Step-by-step explanation:
If a line passing through two points then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
From the given table it is clear that the line passing thought the points (4,100) and (5,125).
[tex]y-100=\frac{125-100}{5-4}(x-4)[/tex]
[tex]y-100=25(x-4)[/tex]
[tex]y-100=25x-100[/tex]
[tex]y=25x[/tex]
The value of this function at x=12 is
[tex]y=25(12)=300[/tex]
From the given table it is clear that the line passing thought the points (0,0) and (2,60).
[tex]y-0=\frac{60-0}{2-0}(x-0)[/tex]
[tex]y=30x[/tex]
The value of this function at x=12 is
[tex]y=30(12)=360[/tex]
The difference between y value in the graph and in the table at x=12 is
[tex]360-300=60[/tex]
The value of y be on the graph than is 60 more than the y value in the table when x = 12. Therefore the correct option is C.

The equation y = ax describes the graph of a line. If the value of a is negative, the line
The equation y = ax represents a straight line with slope a. If a is negative, the line slopes downward to the right, not down and to the left.
The equation y = ax describes the graph of a line. The & in the equation appears to be a typo and should likely refer to a. The constant a represents the slope of the line. When the slope a is negative, the line slopes downward as it moves to the right on a coordinate plane. This is because a negative slope indicates that as the independent variable (usually the x-axis) increases, the dependent variable (y-axis) decreases. A line with a negative slope is straight, and its steepness depends on the absolute value of the slope a. Thus, the line goes down and to the left.

Triangle DEF is congruent to GHJ by the SSS theorem. Which rigid transformation is required to map DEF onto GHJ?
dilation
reflection
rotation
translation
Answer: The correct option is 4, i.e., translation.
Explanation:
It is given that the triangle DEF is congruent to GHJ by the SSS theorem.
From the given figure it is noticed that the triangle DEF and GHI are isosceles triangle.
Reason for correct option:
In transition the side and angles of the shape are not effected and the figure transfers from one place to another place without making any other change.
Since the both triangle are congruent and the position of all sides and angles are same, therefore option 4 is correct.
Reason for incorrect option:
In dilation the size of the figure is either stretched or compressed according to the scale factor k. But in the given figure the size of both triangles are same it means option A is incorrect.
In reflection the distance of all the point in preimage and all the image are same from the central line. Any central line does not exist in given figure. SO, the option B is incorrect.
In rotation the side length and angles are not affected but the position are not same, therefore the option C is incorrect.
Answer: Translation
Step-by-step explanation:
Given: Triangle DEF is congruent to GHJ by the SSS theorem.
From the given picture two sides of both triangles are equal therefore, the triangle DEF and GHI are isosceles triangle.
We know that a transition is a kind of rigid motion used in geometry to trace a function that moves an object a particular distance that maps produces images.
Since the both triangle are congruent and just position of triangle GHJ is shifted to the right and down.
Therefore, the transition is rigid transformation which is required to map DEF onto GHJ

A company has a $150 budget to provide lunch for its 20 employees. The options are to provide either roast beef sandwiches, which cost $5 apiece, or tuna sandwiches, which also cost $5 apiece. The company also wants to use the entire budget. Suppose r represents the number of roast beef sandwiches it provides and t represents the number of tuna sandwiches. Which statement is correct?
A. The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r-t=20 and 5r+5t=150.
B. The company can provide lunch for all 20 employees and use the entire budget because there is a solution to the system of equations r+t=20 and 5r+5t=150.
C. The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r-t=20 and 5r-5t=150.
D. The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150.
Answer: D. The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150.
Step-by-step explanation:
Let 'r' represents the number of roast beef sandwiches it provides and 't' represents the number of tuna sandwiches.
Then, the total number of roast beef sandwiches and tuna sandwiches is equal to the number of employees :
[tex]r+t=20[/tex]....................(1)
Also, the cost of each roast beef sandwich and cost of each tuna sandwich is same as $5.
If company wants to use the entire budget of $150, then we have another equation :-
[tex]5r+5t=150\\\5(r+t)=150[/tex]
If we divide 5 on both sides we get
[tex]r+t=30[/tex].............................(2)
When we compare equation (1) and (2) we get 20=30 but it is not possible therefore the system has no solution.
Therefore, the correct statement is "The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150."
