The composition between the functions f(x) = x and g(x) = 2 is equal to (f ° g) (x) = 2. (Correct choice: B)
What is the result of a composition between two functions?
The composition is a binary operator between two functions, in which the input of the first function is substituted by the second function. This operation is defined by the following expression:
(f ° g) (x) = f[g(x)]
If we know that f(x) = x and g(x) = 2, then the composition between the two functions is:
(f ° g) (x) = 2
Then, the composition between the functions f(x) = x and g(x) = 2 is equal to (f ° g) (x) = 2. (Correct choice: B)

Which is an equation of a direct proportion?
A. =1/3−2
B. =3/
C. =−3+4
D. =−3
Answer:
D. y=-3x
Step-by-step explanation:
Direct Proportion
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]\displaystyle \frac{y}{x}=k[/tex]
Where k is the constant of proportionality.
Solving for y:
y=kx
The only choice representing a direct proportion is:
D. y=-3x
Answer:
D
Step-by-step explanation:
if x+2y =3 and 2x+y=3 then find x²+y²
Answer:
x² + y² = 2
Step-by-step explanation:
Given
x + 2y = 3 → (1)
2x + y = 3 → (2)
Rearrange (2) expressing y in terms of x by subtracting 2x from both sides
y = 3 - 2x → (3)
Substitute y = 3 - 2x into (1)
x + 2(3 - 2x) = 3 ← distribute and simplify left side
x + 6 - 4x = 3
- 3x + 6 = 3 ( subtract 6 from both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Substitute x = 1 into (3) and evaluate for y
y = 3 - 2(1) = 3 - 2 = 1
Thus
x² + y² = 1² + 1² = 1 + 1 = 2

Answer:
value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]
Option D is correct.
Step-by-step explanation:
We are given:
[tex]a=b^2c^2d \:and\: d=\frac{1}{a}[/tex]
We need to find a in terms of b and c
We have: [tex]a=b^2c^2d[/tex]
Put value of d [tex]d=\frac{1}{a}[/tex]
[tex]a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc[/tex]
So, value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]
Option D is correct.

Answer:
A.
Step-by-step explanation:
subtract two y points and the corresponding x points
so if you choose to subtract 20 and 15, you get 5
then you would subtract 4 and 2, you would get 2
put them in y/x fraction: 5/2
this simplifies to 2 1/2

What is the solution to the open sentence?
4x – 4 = 2x + 2
Answer:
x =3
Step-by-step explanation:
4x – 4 = 2x + 2
Solving for x
Subtract 2x from each side
4x-2x – 4 = 2x-2x + 2
2x-4 = 2
Add 4 to each side
2x-4+4 = 2+4
2x = 6
Divide each side by 2
2x/2 = 6/2
x =3

at the olympic games, many events have several rounds of competition. one of these events is the men's 100100100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 888 finishers in the semifinal round at the 201220122012 olympics. the lower dot plot shows the times of the same 888 swimmers in the final round.
The variance semifinal round data, s² ≈ 0.10411
The variance of the final round data, s² ≈ 0.26
Semifinal Round
∑(t × f(t)) = 426.5, ∑f(t) = 8
Average = mean = ∑ (t × f(t))/∑f(t)
Therefore;
In semifinal round average time = [tex]\frac{426.5}{8}[/tex]=53.3125
∑(t² × f(t)) = 22,738.51, ∑f(t) = 8
sample variance = (∑x²·f(t) - ((∑×·f(t))²)/∑f(t))/ ∑f(t) -1
s²=0.10411

In final round average time =[tex]\frac{425.5}{8}[/tex]=53.1875
∑(t² × f(t)) = 22,633.07, ∑f(t) = 8

Answer:
C.None of the above
Step-by-step explanation:
Let's consider the first answer choice:
The times in the semifinals were faster on average than the times in the finals.
We don't have to calculate the mean values of each distribution because we can see visually that the center of the final round distribution is lower than the center of the semifinal round distribution.
Since lower times are faster, we can't say that the times in the semifinals were faster on average than the times in the finals.
Now, let's consider the second answer choice:
The times in the finals vary noticeably less than the times in the semifinals.
We can see visually that the final round distribution is more spread out than the semifinal round distribution. We could calculate MAD or IQR from these displays, but we can see that the range of the final round distribution is larger.
So we can't conclude that the times in the finals vary noticeably less than the times in the semifinals.
What is the coefficient of the third term in the binomial expansion of (a + b)6? 1 15 20 90
Answer: 15
Step-by-step explanation:
(r+1)th term of [tex](a+b)^n[/tex] is given by:-
[tex]T_{r+1}=\ ^nC_r(a)^{n-r}b^r[/tex]
For [tex](a+b)^6[/tex] , n= 6
[tex]T_3=T_{2+1}=\ ^6C_2(a)^{6-2}(b)^2\\\\[/tex]
[tex]=\ \dfrac{6!}{4!2!}a^4b^2\ \ \ [^nC_r=\dfrac{n!}{r!(n-r)!}]\\\\=\dfrac{6\times5\times4!}{4!\times2}a^4b^2\\\\=3\times5a^4b^2\\\\ =15a^4b^2[/tex]
Hence, the coefficient of the third term in the binomial expansion of [tex](a+b)^6[/tex] is 15.

Segundo o Instituto Nacional de Pesquisas Espaciais (Inpe), de janeiro a setembro de 2019, foram registrados 4.660 focos de incêndio, em 2020 foram registrados 14.489 focos. Qual é a porcentagem de aumento de focos de incêndio em 2020 em comparação com os focos registrados em 2019?
A fórmula de aumento percentual é fornecida como
Aumentar / tamanho inicial × 100
Aumento = 14489 focos de incêndio - 4660 focos de incêndio
= 9829 focos de incêndio
Aumento percentual = 9829/4660 × 100
= 210.92274678 %

Step-by-step explanation:
Simply apply the distance formula.

A theater is showing 2 comedies, 1 musical, and 5 action films. Each movie has 3 matinee showtimes and 7 evening performances. Each type of movie and showtime is equally likely to be chosen. If 12,400 people see a movie, how many will be expected to choose a musical during an evening showtime? A 1,085 C 1,240 B 1,189 D 1,550
Answer: 1550
Step-by-step explanation:
Number of people to see the movie = 12400
Number of comedies = 2
Number of musical = 1
Number of action films = 5
The number of people that'll be be expected to choose a musical during an evening showtime will be:
= 1/8 × 12400
= 1550
