Answer:

-10

Step-by-step explanation:

The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.

The values of h'(x) is h'(x) = 20 [tex](e^{2x} + x) ^{3}[/tex]  (2[tex]e^{2x}[/tex] + 1 ).

Option C is the correct answer.

Given,

f(x)=5x^4 and g(x)=e^2x+x.

If h is the function defined by h(x)=f(g(x)),

We need to find h′(x).

We have,

dx/dx = 1

d[tex]x^{n}[/tex]/dx = n[tex]x^{n-1}[/tex]

d[tex]e^{x}[/tex]/dx = [tex]e^{x}[/tex]

d[tex]e^{n}[/tex]/dx = [tex]ne^{n}[/tex]

d(cx)/dx = c(dx/dx) = c

We have,

- f(x)=5[tex]x^{4}[/tex] ______(1)
- g(x)=[tex]e^{2x}[/tex]+x ______(2)

- h(x)=f(g(x)) _______(3)

Now,

h(x) = f ( [tex]e^{2x}[/tex]+x )

From (1)

h(x) = 5[tex](e^{2x} + x) ^{4}[/tex] ______(4)

Now,

Differentiate (4)

h'(x) = 5 d[tex](e^{2x} + x) ^{4}[/tex]/dx

h'(x) = 5 x 4 [tex](e^{2x} + x) ^{3}[/tex] d [tex](e^{2x} + x)[/tex] / dx

h'(x) =20 [tex](e^{2x} + x) ^{3}[/tex] ( d[tex]e^{2x}[/tex]/dx + dx/dx )

h'(x) = 20 [tex](e^{2x} + x) ^{3}[/tex]  (2[tex]e^{2x}[/tex] + 1 )

Thus the values of h'(x) is h'(x) = 20 [tex](e^{2x} + x) ^{3}[/tex]  (2[tex]e^{2x}[/tex] + 1 ).

Option C is the correct answer.

Answer:

B

Step-by-step explanation:

[tex]\frac{x}{5}[/tex] + 4 = 1 ( subtract 4 from both sides )

[tex]\frac{x}{5}[/tex] = - 3 ( multiply both sides by 5 to clear the fraction )

x = 5 × - 3 = - 15 → B

Answer:

Step-by-step explanation:

∠5 = ∠1             {Alternate exterior angles are congruent}

8x - 19 = 7x - 3

Add 19 to both sides

8x = 7x - 3 + 19

8x = 7x + 16

Subtract 7x from both sides

8x - 7x = 16

   x = 16

∠5 = 8x - 19

    = 8*16 - 19

    = 128 - 19

 ∠5 = 109

∠5 + ∠4 = 180     {linear pair]

109 + ∠4 = 180

         ∠4 = 180 - 109

∠4 = 71°

Queremos encontrar diferentes cosas en un experimento dado. Daremos una breve explicación para cada respuesta.

a) La población es el grupo de gente que se estudia, en este caso la medicina es para diabeticos, por lo que la población en este caso sería toda la gente que padece dicha enfermedad.

b) La muestra se refiere a la parte de la población que participa en el experimento, en este caso son 10,000 personas con diabetes.

c) El parametro de interes, es decir, lo que le interesa estudiar a los cientificos, será la efectividad del medicamento que estan desarrollando.

d) Sí, se conoce el valor del parametro, se sabe que en 90% de los casos es efectivo, escribiendo esto de forma decimal, podemos decir que el medicamento es efectivo con una probabilidad de 0.9.

Step-by-step explanation:

Since the line is going up to the right it is a positive slope. Therefore it can't be a or d.

The slope is 2/3 because to connect the dots you have to go up 2 and to the right 3.

This is an exponential growth function.

If we look at the number that is raised to the power of x, it is greater than 1. Though there is a fraction within this equation, it is not affected by the exponential.

Answer:

To overcome such type of real world problems we use union. Unlike structures union occupies single memory location to store all its members. So, unions are helpful when you want to store value in single member from a set of members. Size of union is defined according to size of largest member data type.

Step-by-step explanation:

In union, all members share the same memory location. For example in the following C program, both x and y share the same location. If we change x, we can see the changes being reflected in y. #include <stdio.h> // Declaration of union is same as structures.
