Answer:
[tex] f(-1) =\boxed{-11}\\ f(0) =\boxed{-4}\\f(2) =\boxed{14}[/tex]
Step-by-step explanation:
[tex]f(x)=\begin{cases} 9x -2 \:\: x < 0\\ 9x-4 \:\: x \geq 0\end{cases}\\\\\because \; -1 \: is \: less\: than \: zero\\\therefore f(-1) \: lies \: in \: the \: interval\: x<0\\\\f(-1) = 9(-1) -2 = -9-2 = -11\\f(-1)=\boxed{-11}\\\\Similarly,\: f(0) \:\&\: f(2)\: lies \: in \: the \: interval\: x\geq 0\\\\f(0) = 9x-4 = 9(0) - 4 = 0-4 = -4\\f(0) = \boxed{-4}\\\\f(2)=9x-4 = 9(2)-4 = 18-4 = 14\\\\f(2)=\boxed{14}[/tex]

Hey There!
To find the area of a regular hexagon we use the formula
[tex]A = \frac{1}{2} ap[/tex]
a = apothem
p = perimeter
to find the peremeter we multiply the side length by the number of sides
which is 6
6x6=36 so the perimeter is 36
now we just plug it into the area of a hexagon formula
36x5.2=187.2
[tex]\frac{187}{2} =93.6[/tex]
so the area is 93.6 cm ³
An artist mixes paint to make new colors.
She uses 13 cup of red paint and 13 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available,
how many batches of orange paint can she make?
Enter your answer in the box.
Answer:
The artist can make six batches of orange paint and it remains one cup of yellow paint
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of red paint for one batch of orange paint = 1/3 of a cup
Amount of yellow paint for one batch of orange paint= 1/3 of a cup
Amount of red paint available = 2 cups
Amount of yellow paint available = 3 cups
2. How many batches of orange paint can she make?
2 cups of red paint = 6/3 = 6 batches of orange paint
3 cups of yellow paint = 9/3 = 6 batches and it remains one cup of yellow paint
The artist can make six batches of orange paint and it remains one cup of yellow paint
Step-by-step explanation:
Choose the polynomial that is written in standard form 7x^5+8x^8+27x
Don’t need the answer just couldn’t find the question lol so the answer is 3
Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3
Find the value of x when 27 - 2x + 1 = 729+ 2x + 3

Answer:
I. p = 7
II. 17 litres
Step-by-step explanation:
I. Determination of the value of p
Mean = 17.7
p =.?
Let the number of litre be L
Let the number of motorist be M
Mean = summation LM / summation M
Summation of LM = (16×11) + (17×10) + (18×p) + (19×4) + (20×8)
= 176 + 170 + 18p + 76 + 160
= 582 + 18p
summation M = 11 + 10 + P + 4 + 8
= 33 + p
Mean = summation LM / summation M
17.7 = 582 + 18p / 33 + p
Cross multiply
17.7(33 + p) = 582 + 18p
584.1 + 17.7p = 582 + 18p
Collect like terms
584.1 – 582 = 18p – 17.7p
2.1 = 0.3p
Divide both side by 0.3
p = 2.1 / 0.3
p = 7
II. Determination of the median number of litre.
Let the number of motorist be M (i.e the frequency)
summation M = 11 + 10 + P + 4 + 8
p = 7
summation M = 11 + 10 + 7 + 4 + 8
summation M = 40
The median is the middle term i.e
Median = (summation M / 2)ᵀʰ motorist
Median = (40 / 2)ᵀʰ motorist
Median = 20ᵀʰ motorist
Considering the table in the question above, the 20ᵀʰ motorist has 17 litres.
Therefore, the median number of litres is 17 litres.
how do i find the measure of R or whatever big confushion help
Answer:
m∠R= 87°
Step-by-step explanation:
The angles in a polygon add up to (n-2)180
(5-2)180= 540°
You can set up an equation to add all the angles together equaling 540°.
Once you solve for x, plug that back into the formula for the angle of R(7x-11)
Which of the following options have the same value as 40% of 84?
Answer:
33.6
Step-by-step explanation:
84(0.4) = 33.6
.....
Answer:
40% of 84 is 33.6
Step-by-step explanation:
No following options are listed, but I will solve for 40% of 84
First set these up into an equation
40/100 = x/84
Cross multiply
40 × 84 = 100 × x
3360 = 100x
Divide both sides by 100 to isolate the variable
33.6 = x

los conjuntos numericos se relacionan entre si, los irracionales son caso aparte de los conjuntos numericos, cual sera la razon por lo que esto sucede?
Answer:
Los conjuntos numéricos que se relacionan entre sí son:
Naturales, enteros y racionales.
Los números naturales son aquellos números que se pueden escribir como sumas de 1.
Los números enteros son todos los números naturales, y agregamos el número cero y los números negativos.
Los números racionales son aquellos números que se escriben como cociente de dos números enteros. Acá también podés notar que:
7 = 7/1
entonces todo número entero se puede escribir como el cociente de dos enteros, lo que implica que el conjunto de los números racionales también engloba al conjunto de los enteros.
Entonces si N es el conjunto de los números naturales, Z es el conjunto de los números enteros, y Q es el conjunto de los números racionales, tenemos que:
N ⊂ Z ⊂ Q.
Ahora por otro lado, el conjunto de los números irracionales es aquel que no se puede escribir como cociente de dos números enteros. Con esto ya podemos concluir que no existe ningún elemento compartido entre ninguno de los conjuntos anteriores y este conjunto, y esto se debe a la definición de número irracional, como no se puede construir como el cociente de números enteros, entonces no hay forma de relacionarlo con ninguno de los otros conjuntos.

The degree of the function is the highest exponent, which is 5.
The y-intercept is the value when x=0, which is 0.
The function will have 5 zeros since there are 5 distinct factors.
The end behavior will approach negative infinity as x approaches negative infinity and positive infinity as x approaches positive infinity [since the degree is odd and the leading coefficient is positive].
The roots/zeros will be at 0, 5, 3, -2, -4 [setting each factor equal to 0]

a. 1
b. 2
c. 3
d. 4
Answer:
3
Step-by-step explanation:
m<3 is the only interior adjacent angle. It is interior because it is inside a triangle, and it is adjacent because it is touching another angle. Hence, < 3 is the adjacent interior angle.
