The derivatives for this problem are given as follows:

a) [tex]f^{\prime}(x) = -4\sin{x} + \frac{1}{x + 1}[/tex]

b) [tex]f^{\prime}(x) = \sec{x}\tan^{2}{x} + \sec^3{x}[/tex].

The derivative of the sum is the sum of the derivatives.

In this problem, the function is:

[tex]f(x) = 4\cos{x} + \ln{(x + 1)}[/tex]

Using a derivative table for the derivatives of the cosine and the ln, the derivative of the function is:

[tex]f^{\prime}(x) = (4\cos{x})^{\prime} + (\ln{(x + 1)})^{\prime}[/tex]

[tex]f^{\prime}(x) = -4\sin{x} + \frac{1}{x + 1}[/tex]

What is the product rule?

The derivative of the product is given as follows:

[tex](f(x) \times g(x))^{\prime} = f^{\prime}(x)g(x) + g^{\prime}(x)f(x)[/tex]

In this problem, we have that:

Hence the derivative is:

Answer: constant of proportionality = 0.75

How to find constant of proportionality?

Constant of proportionality is the same as the slope of a straight line.

Slope formula is given by:

[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]

Here take two points: (0, 0), (4, 3)

[tex]So, \sf \ slope : \dfrac{3-0}{4-0} = \dfrac{3}{4} \quad or \quad 0.75[/tex]

Hence, the constant of proportionality is 0.75

Answer:

Constant of proportionality = 0.75

Step-by-step explanation:

To find the constant of proportionality of a graph that goes through the origin:

• First select a point on the graph whose coordinates you can easily read; in this case such a point is already marked (4, 3).

• Next, simply divide the y-value by the x-value of the coordinates to find the constant of proportionality:

Constant of proportionality = y ÷ x

                                             ⇒ 3 ÷ 4

                                             ⇒ 0.75

Answer:

m = 10/3

(as a decimal: m = 3.333...)

Step-by-step explanation:

5m - 8 = 2m + 2

 5m - 8 = 2m + 2

- 2m       - 2m              (make all "m" on one side to isolate variable)

 3m - 8 = 2    

      + 8 + 8              (get m entirely on 1 side)

3m = 10

÷3      ÷3                         (divide by 3 to get 1m)

m = 10/3

(as a decimal: m = 3.333...)

Answer:

О  x = 10 3/4

[tex]x = 10\frac{3}{4}[/tex]

Step-by-step explanation:

-1/5 ( x + 1 3/4) = -2 1/2

Particularly:

1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4

-2 1/2 = -2 - 1/2 = -4/2 - 1/2 = -5/2

Then:

-1/5 (x + 7/4) = -5/2

(x*-1/5 + 7/4*-1/5) = -5/2

(-x/5 + ((7*-1) / (4*5))) = -5/2

-x/5 + (-7/20) = -5/2

-x/5 - 7/20 = -5/2

-4x/20 - 7/20 = -50/20

-4x - 7 = -50

-4x =  -50  + 7

-4x = -43

x = -43/-4

x = 43/4

43/4 = 40/4 + 3/4 = 10 + 3/4 = 10 3/4

The value of the stock account at the end of each day is  mathematically given as

x=1010$.

Generally, The price of the stock would have climbed by 1000 points, which is equal to 0.1 times 1000, or 10 dollars.

Therefore, the price of the stock would be 1010 dollars plus 10 dollars, which is 1020 dollars.

In conclusion, Cheryl was required to pay a ten dollar administrative fee, and this cost would be deducted from the stock price.

Following this logic, the price of the stock would be

The least to greatest slope, the segments are B, C, and A.

We have given that,

The water level of a tank every minute since it began filling is indicated by segments A, B, and C on the graph below.

A graph represents the water level to fill the tank on Y-axis per time on X-axis.

The rate of increase of water level is indicated by the slope of the segment. The slope is the ratio of rise to run, and is related to the angle the segment makes with the +x axis.

Segments that have more rise for the same run have greater slope. Segments that make a larger reference angle with the +x axis have a larger slope.

Here, segment B has the least slope, followed by C, then A, which has the largest slope.

Using the binomial distribution, it is found that there is a 0.3222 = 32.22% probability that at least 3 Canadian are on CERB in the sample.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

The values of the parameters are:

n = 10, p = 0.2.

The probability that at least 3 Canadian are on CERB in the sample is:

[tex]P(X \geq 3) = 1 - P(X < 3)[/tex]

In which:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).

Then:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{10,0}.(0.2)^{0}.(0.8)^{10} = 0.1074[/tex]

[tex]P(X = 1) = C_{10,1}.(0.2)^{1}.(0.8)^{9} = 0.2684[/tex]

[tex]P(X = 2) = C_{10,2}.(0.2)^{2}.(0.8)^{8} = 0.3020[/tex]

Then:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.1074 + 0.2684 + 0.3020 = 0.6778.

[tex]P(X \geq 3) = 1 - P(X < 3) = 1 - 0.6778 = 0.3222[/tex]

0.3222 = 32.22% probability that at least 3 Canadian are on CERB in the sample.

Answer: A, C, C.

Step-by-step explanation:

Notice that

5 - 3 = 2

11 - 5 = 6

29 - 11 = 18

and these differences form a geometric sequence,

{2, 6, 18, ...} = {2×3⁰, 2×3, 2×3², ...}

so a reasonable guess for the next number in the sequence might be 2×3³ = 54.

The sequence might be 2×3^3^3 = 54.

We notice that 5 - 3 = 2

11 - 5 = 6

29 - 11 = 18

and these differences form a geometric sequence,

A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant.

{2, 6, 18, ...} = {2×3^0, 2×3^1, 2×3^3, ...}

This is a measure of the error that we get when we use a random sampling model.

It can be found by the formula:

Considerando la definición de divisor común mayor:

Los divisores de un número natural son los números naturales que lo pueden dividir, resultando de cociente otro número natural y de resto 0. Ser divisor es lo recíproco a ser múltiplo.

En otras palabras, un número es divisor de otro si está contenido una cantidad entera de veces. Por lo tanto, al dividir el número por el divisor el cociente debe resultar un número entero (que no sea un número decimal) y el residuo o resto de la división sea 0.

Se denomina máximo común divisor al mayor número que divide exactamente a dos o más números a la vez.

En otras palabras, el divisor común mayor es el mayor de los divisores que tienen en común dos o más números.

Para calcular el divisor común mayor se debe realizar los siguientes pasos:

Para calcular la cantidad de grupos se debe calcular el divisor común mayor. Para ello, en primer lugar se descomponen los números:
