Partial Derivatives

d/dx(8 e^(4 x) sin(7 y))

Factor out constants:

= 8 (d/dx(e^(4 x))) sin(7 y)

Using the chain rule, d/dx(e^(4 x)) = (d e^u)/(du) (du)/(dx), where u = 4 x and d/(du) (e^u) = e^u:

= e^(4 x) (d/dx(4 x)) 8 sin(7 y)

Factor out constants:

= 4 (d/dx(x)) 8 e^(4 x) sin(7 y)

Simplify the expression:

= 32 e^(4 x) (d/dx(x)) sin(7 y)

The derivative of x is 1:

= 32 e^(4 x) sin(7 y)

**46 of 181 students that watched TV ate pizza and the same 46 students of  the 150 students that ate pizza watched TV.

Answer:

17

Step-by-step explanation:

Angle 2 and angle 4 are alternate exterior angles so they congruent angles which means they have same angle measurement.

To find the measure of angle 2 we first need to find the value of x.

And to do that we can write the following equation based on the information we have in hand:

6x + 8 = 4x + 11 transfer like terms to the same side of the equation

6x - 4x = 11 - 8 add/subtract like terms

2x = 3 divide both sides by 2

x = 1.5 now to find the measure of angle 2 replace x with 1.5

6×(1.5)+8 = 17

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred. Percentages are a measure of frequency. The sign used to represent percentages is %.

The percent increase in his bill from May to July = (bill in July / bill in May)^(1/number of months) - 1

Answer:

A

Step-by-step explanation:

substitute the values from the replacement set into the right side of the equation to find which values of x make the equation true.

x = - 32

[tex]\frac{-32}{4}[/tex] + 5 = - 8 + 5 = - 3 ← True

x = 8

[tex]\frac{8}{4}[/tex] + 5 = 1 + 5 = 6 ≠ - 3 ← False

x = 32

[tex]\frac{32}{4}[/tex] + 5 = 8 + 5 = 13 ≠ - 3 ← False

the solution is therefore x = - 32

The fraction 24/56 can be simplified to 3/7, and we can't keep simplifying this.

Here we want to simplify the fraction 24/56. To do so, we need to find the greatest common factor between 24 and 56, to find that, we need to write both of these numbers as a product of their prime factors.

We will get:

24 = 2*2*2*3

56 = 2*2*2*7

We can identify the greatest common factor between parenthesis:

24 = (2*2*2)*3

56 = (2*2*2)*7

So the greatest common factor is 2*2*2 = 8, then we can divide both numerator and denominator by 8, we will get:

24/8 = 3

56/8 = 7

Then the fraction 24/56 can be simplified to 3/7, and we can't keep simplifying this.

The range of the salary will be the closed interval [23,200, 26,800].

The absolute function is also known as the mode function. The value of the absolute function is always positive.

The absolute function is given as

f(x) = | x |

A new hire at one organization may expect to get an average beginning pay of $25,000 per year. The absolute divergence from the real compensation is no more than $1800.

Let 'x' represent the actual salary. Then the inequality is given as,

|x - 25,000| ≤ 1800

- 1,800 ≤ x - 25,000 ≤ 1,800

25,000 - 1,800 ≤ x ≤ 25,000 + 1,800

23,200 ≤ x ≤ 26,800

The range of the salary will be the closed interval [23,200, 26,800].

Answer:

  g(x) = 3x +5

Step-by-step explanation:

You want the function that results from translating f(x) = 3x upward by 5 units.

The y-coordinate of a point tells how far above the x-axis it is. Adding 5 to the y-coordinate will move that point 5 units farther above the x-axis, which is to say 5 units upward.

The y-coordinate of a point on a graph is the value of the function of the x-coordinate of that point. That is, each point is (x, f(x)). If we want to translate that point 5 units upward, we add 5 to the function value:

  (x, f(x) +5) . . . . . graph translated 5 units up

Using the given definition of f(x), this becomes ...

  (x, 3x +5)

The translated function is defined as g(x), so we have ...

  (x, g(x)) = (x, 3x +5)

or ...

  g(x) = 3x +5

The slope of a line that passes through the ordered pairs (0,1) and (3,5) would be m = 4/3.

Slope tells how vertical a line is.

The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

WE have been given line that passes through the ordered pairs (0,1) and (3,5).

Slope = m

Therefore,

[tex]m = \dfrac{y-q}{x-p}\\\\m = \dfrac{5 -1}{3-0}\\\\m = \dfrac{4}{3}[/tex]

Hence, the slope of a line that passes through the ordered pairs (0,1) and (3,5) would be [tex]m = \dfrac{4}{3}[/tex].

In this problem we have a case of unit conversions, in which we must find what measure in a unit offers the best approximation to other represented in other unit. Please notice that a centimeter equals 25 / 762 feet and 50 / 127 inches. Now we proceed to calculate the equivalent quantities in feet and inches by simple rule of three:

x = 270 cm × (25 / 762 feet / cm)

x ≈ 8.858 feet

x = 270 cm × (50 / 127 inches / cm)

Polynomial equation with integer coefficients that has roots x= -1 and

x = -6 is equal to x² +7x +6=0.

As given in the question,

Given roots for the polynomial equation with integer coefficient are

x = -1 ⇒ x + 1=0

x = -6 ⇒ x + 6 =0

Polynomial equation is

( x + 1) ( x + 6) =0

⇒ x² + 1x + 6x + 6 =0

⇒ x² + 7x + 6 =0

Therefore, polynomial equation with integer coefficients that has roots x= -1 and x = -6 is equal to x² +7x +6=0.
