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.

The composition between the functions f(x) = x and g(x) = 2 is equal to (f ° g) (x) = 2. (Correct choice: B)

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)

Step-by-step explanation:

Somos informados:

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 %

≈ 211%

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:

the answer is 6

Step-by-step explanation:

Answer:

BC = 4, CD = 6

Step-by-step explanation:

Simply apply the distance formula.

(4 - 0) + (4 - 4) = 4

|(6 - 4, 0 - 4)| = 2 + 4 = 6

We take the absolute value when one term is negative because distance always ignores negatives.

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

Step-by-step explanation:

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

Final round

In final round average time =[tex]\frac{425.5}{8}[/tex]=53.1875

∑(t² × f(t)) = 22,633.07, ∑f(t) = 8

The variance of the final round data, s² ≈ 0.26

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.

Where k is the constant of proportionality.

Solving for y:

y=kx

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]
