The required linear function is given by-
x = 3 4 5 6
y = 6 5 4 3
Option 2 is correct.
From the option of tables the option that shows linear function is to be chosen.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Options 1), 3), and 4) can be omitted because the relation between the column of the table is not a linear function and is irrelevant to each other. While option 2) contains the table that shows a linear relationship by the following expression,
y = -x + 9
The data below give the information for the expression above
x = 3 4 5 6
y = 6 5 4 3
Tus, the required linear function given by option 2 is correct.

The order of matrix A + B is __.
Answers
Answer:
last one 4 x 1
Step-by-step explanation:
Order of the matrices must be the same in order to add them up
Adding matrices mean adding corresponding elements together
Order of matrix is 4 rows and 1 column
Answer:
4 x 1 ( 4 rows and one column)
Step-by-step explanation:
Recall the definition for order of a matrix: The number of rows times the number of columns.
So, in this case, we are adding matrix A which is 4 rows and 1 column to matrix B which is also of 4 rows and one column, obtaining a third matrix that has also 4 rows and one column:
[tex]\left[\begin{array}{cccc}-9\\0\\3\\-1\end{array}\right] +\left[\begin{array}{cccc}0\\4\\-6\\2\end{array}\right] =\left[\begin{array}{cccc}-9\\4\\-3\\1\end{array}\right][/tex]
The resultant A + B is also of 4 rows and one column

Answer:
Martins triangle is a right angled triangle with hypotenuse of 5cm adjacent of 4cm and opposite side of 3cm.Step-by-step explanation:
A triangle that has one of his angles to be 90° is known as a right angled triangle. The triangle has one right angle and two acute angles. The three sides of the triangle are namely the hypotenuse (which is the longest side), the opposite and the adjacent. One of the side of the triangle can be written in terms of the other using the theorem called pythagoras. According to the theorem;
[tex]hyp^{2} = opp^{2} + adj^{2} \\[/tex]
Based on the values of the sides given
hypotenuse = 5cm (being the longest side)
[tex]hyp^{2} = 3^{2}+4^{2} \\ hyp^{2} = 25\\hyp = \sqrt{25}\\ hyp = 5cm[/tex]
This shows that the triangle is a right angled triangle as described by Martin since we are able to express one side in terms of the other.

A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses: 10, 5, 18, 9, 17, 12 Find the median and mean number of hours for these students. If necessary, round your answers to the nearest tenth.
Answers
Answer:
Mean = 11.8
Median = 11
Step-by-step explanation:
Here we are asked to calculate the median and the mean for these set of numbers
Let’s start with the mean
The mean refers to the average, we simply add all the numbers together and divide by their count.
That would be;
Arithmetic mean = (10+ 5 + 18 + 9 + 17 + 12)/6 = 71/6 = 11.833 which is 11.8 to the nearest tenth
To get the median, what we do is to first rearrange the values we have from the lower to the highest.
That would be;
5,9,10,12,,17,18
Looking at the numbers after rearranging, the two middle numbers we have are 10 and 12.
So we add these together divide by 2.
That would be (10+12)/2 = 22/2 = 11

Answers
Answer:
the answer is A
Step-by-step explanation:
if u see, to get Y2 on its own u have to first multiply x2-x1 on both sides
m(x2-x1)=y2-y1

Where m is the slope and [tex]y_1[/tex] and [tex]y_2[/tex] and [tex]x_1[/tex] and [tex]x_2[/tex] are coordinates of the axis.
if u see, to get [tex]Y_2[/tex] on its own u have to first multiply [tex]x_2-x_1[/tex] on both sides
[tex]m(x_2-x_1)=y_2-y_1[/tex]
and then to get Y2 alone u need to add Y1 to both sides

1. The height of a cylindrical tank is 9.5 feet. The diameter of this tank 1.5 feet longer than the height. The tank was holding water at full capacity, but someone consumed one-seventh of the water. Which is closest to the volume of the remaining water in the tank?
A 105 cubic feet
B 165 cubic feet
C 246 cubic feet
D 287 cubit feet
Answers
To solve this problem we first need to calculate the volume of the tank at full capacity, since it is a cylinder we can use the appropriate formula shown below:
volume = pi*r²*h
Where r is half the diameter. Since the diameter of this tank is 1.5 feet longer than the height and the height is 9.5 feet, then the diameter is equal to 11 feet, so the radius must be r = 11/2 = 5.5 feet. We can now use the formula:
volume = pi*(5.5)²*9.5 = 902.815 feet³
Since someone consumed 1/7 of the water, the remainder must be 6/7 of the total volume. So we have:
remainder volume = (6/7)*volume = (6/7)*902.815 = 773.841 feet³
For what value of x do the expressions 2/3 x+2 and 4/3 x-6 have the same value? *
Answers
Answer: 42
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
Hi, to answer this we have to equal both equations given and solve for x.
2/3x+2 = 4/3x-6
Solving for x:
2/3x-4/3x= -6-2
-2/3x = -8
x = -8/ (-2/3)
In conclusion, when the value of x is equal to 12, both expressions will have the same value.
Una catedral esta situada en la cima de una colina. Cuando la punta de su torre se observa desde el ple de la loma, el angulo de elevacion es de 48°. Cuando se ve desde un punto a una distancia de 6096 m del pie del promontorio, el angulo de elevacion es de 41° la cuesta de la colina forma un angulo de 32° Aproxima la altura de la catedral
Answers
Answer:
La altura de la catedral es de 15119,97 m.
Step-by-step explanation:
Para una respuesta única, la pregunta se formula de la siguiente manera:
Una catedral se encuentra en la cima de una colina. Cuando se ve la parte superior de su torre desde la parte inferior de la colina, el ángulo de elevación es de 48 °. Cuando se ve desde un punto a 6096 m del pie del promontorio, el ángulo de elevación es de 41 °, la pendiente de la colina forma un ángulo de 32 ° Se aproxima a la altura de la catedral
Deje que la base de la colina = C
El punto 6096 m de la base = A
La cima de la catedral = B
∴ ∠A = 41 °
∠C = 180-48 = 132 °
∠B = 180 - (41 + 132) = 7 °
[tex]\dfrac{6096}{sin7} = \dfrac{CB}{sin41}[/tex]
∴ CB = 32816.59 m.
Punto E = Base de la catedral.
Punto D = Punto debajo de la base de la catedral al nivel del pie de la colina
Por lo tanto, la altura de la catedral = BE
∡ABE = 90-41 = 49 °
∡CED = 90-32 = 58 °
∴ ∡CEB = 180 - 58 ° = 122 °
De la regla seno tenemos;
[tex]\dfrac{CB}{sin(\angle CEB)} = \dfrac{BE}{sin(\angle ECB)}[/tex]
∠EBA = 90 - 48 = 42°
∠EBC = 42 - 7 = 35°
∠ECB = 180 - 35 - 122 = 23°
[tex]\therefore \dfrac{32816.59 }{sin(122)} = \dfrac{BE}{sin(23)}[/tex]
[tex]BE = \dfrac{32816.59 }{sin(122)} \times sin(23) = 15119.97 \ m[/tex]
La altura de la catedral = 15119,97 m.
Suppose a medium pizza at Vincent's costs $6.75 plus $0.75 for each topping, and the cost of a medium pizza at Original Italian Pizza is $6.15 plus $0.80 per topping. How many toppings would you have to include on your pizza for the price to be the same at both places?
Answers
Answer:
12 toppings
Step-by-step explanation:
To do this, we need to write an equation for each place, and then, equal both equations to solve for this.
Let's call "y" the price of the pizza, and "x" the number of toppings.
At Vincents, pizza costs 6.75 + 0.75 for each topping, so the equation here would be:
y = 6.75 + 0.75x (1)
Now, at italian pizza, a pizza costs 6.15 + 0.80 per topping, so the equation:
y = 6.15 + 0.80x (2)
Now, we don't need to know the actual price of the pizza, we only want to know how many toppings we need to add on both places, so the pizza has the same price. We have both equations, it's time to equal both of them:
Equalling (1) and (2) we have:
6.75 + 0.75x = 6.15 + 0.80x
Now, let's solve for x:
6.75 - 6.15 = 0.80x - 0.75x
0.6 = 0.05x
x = 0.6 / 0.05
x = 12
So the number of toppings to include in the pizza so the price is the same for both places, will have to be 12 toppings.
Answer:
12 toppings and the prize will be the same.
Step-by-step explanation:
Let
number of toppings = a
Medium pizza at Vincent's
cost = 6.75 + 0.75a
Medium pizza at Original Italian Pizza
cost = 6.15 + 0.80a
For the cost to be the same
6.75 + 0.75a = 6.15 + 0.80a
collect like terms
6.75 - 6.15 = 0.80a - 0.75a
0.6 = 0.05a
divide both sides by 0.05
a = 0.6/0.05
a = 12
12 toppings and the prize will be the same.

Find the mean median and mode of the refrigerator prices shown in the table. Witch measurement might be misleading to describing the average cost of a refrigerator?
Answers
Answer:
We need the picture.
Step-by-step explanation:
Unless the data is skewed (which means there is outliers) then you use mean as the most accurate. If you have a skewed graph or outliers then mean would mislead you to believe prices are higher (if you have high outliers) or low (if you have low outliers). Median is typically very accurate. Mode may be inaccurate if you have a lot of prices in a really high or low value.

Answers
Answer:
The volume of the pyramid is 165.4 inches^3
Step-by-step explanation:
In this question, we are asked to calculate the volume of the pyramid with a square base and also with the given height.
To find the area of this pyramid, what we need to do is to multiply the area of the base by the height of the pyramid
From the question, the area of the square base is 11.9 in^2 while the height of the pyramid is 13.9 in
Thus the volume here is simply 11.9 * 13.9 = 165.41 which to the nearest tenth of cubic inch is 165.4 inch^3
