Answer:

\({ \bf{f(x) = \tan x + 9 \sin x }}\)

For gradient, differentiate f(x):

\({ \tt{ \frac{dy}{dx} = { \sec }^{2}x + 9 \cos x }}\)

Substitute for x as π:

\({ \tt{gradient = { \sec }^{2} \pi + 9 \cos(\pi ) }} \\ { \tt{gradient = - 8 }}\)

Gradient of tangent = -8

\({ \bf{y =mx + b }} \\ { \tt{0 = ( - 8\pi) + b}} \\ { \tt{b = 8\pi}} \\ y - intercept = 8\pi\)

Equation of tangent:

\({ \boxed{ \bf{y = - 8x + 8\pi}}}\)

Step-by-step explanation:

The point (−6,0) is on the graph of the line because (−6,0) represents a solution to the equation 5x−6y=−30.

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The equation of the function is given as

5x - 6y = -30

The above equation is a linear equation

For point (5, 0), we have

5 x 5 - 6 x 0 = -30

25 = -30 ---- this is false

For point (-6, 0), we have

5 x -6 - 6 x 0 = -30

-30 = -30 ---- this is true

Hence, the point (−6,0) is on the graph of the line because (−6,0) represents a solution to the equation 5x−6y=−30.

Answer:

Sherry needs to work at least 100 hours.

Step-by-step explanation:

18h - 200 > 1600

18h > 1800

h > 100

The inequality represents how many hours she will need to work in order to have $1600 in her account is given by

h > 100.

We know that the term inequality refers to a mathematical expression in which the sides are not equal.

Let Sherry will need to work for h hours.

Given that Sherry earns $18 an hour.

So, she earns $18h in h hours.

Also given that she has to pay $200 for her car payment.

Then she needs to have at least $(18h - 200)  in her bank account at the end of this month.

Then we can write this as

18h - 200 > 1600

i.e. 18h > 1600 + 200

i.e. 18h > 1800

i.e. h > 100

Therefore the inequality represents how many hours she will need to work in order to have $1600 in her account is given by h > 100.

A triangular prism is a three-dimensional geometric shape that consists of two triangular bases and three rectangular faces connecting them. It is a polyhedron with six faces, nine edges, and six vertices.

The two triangular bases of a triangular prism are congruent and parallel to each other. The rectangular faces are perpendicular to the triangular bases, and their lateral edges connect the corresponding vertices of the triangular bases.

The triangular bases are identical and parallel to each other. Each base has three vertices, three edges, and one face.There are three rectangular lateral faces connecting the corresponding vertices of the triangular bases. Each lateral face has two edges and one face.

The rational function graphed in this problem is defined as follows:

y = -2(x - 1)/(x² - x - 2).

The vertical asymptotes of the rational function for this problem are given as follows:

x = -1 and x = 2.

Hence the denominator of the function is given as follows:

(x + 1)(x - 2) = x² - x - 2.

The intercept of the function is given as follows:

x = 1.

Hence the numerator of the function is given as follows:

a(x - 1)

In which a is the leading coefficient.

Hence:

y = a(x - 1)/(x² - x - 2).

When x = 0, y = -1, hence the leading coefficient a is obtained as follows:

-1 = a/2

a = -2.

Thus the function is given as follows:

y = -2(x - 1)/(x² - x - 2).

Therefore , the solution of the given problem of inequality comes out to be graph 2 shows the solution for this system.

In mathematics, an inequality is a linear connection or a collection of numbers even when there is no equal sign. Equity always comes after equilibrium. When two numbers are not equal, inequality exists. Between equality and inequality, there exist differences. The most common symbol was chosen because when parameters aren't the same or comparable (). Values can be compared using a variety of disparities, no matter how few or numerous they are.

Here,

Given :

=> x + y ≥ 5

and

=> - 3x + 2y ≤-2

So,

=> x ≥ 5- y

=> - 3(5- y) + 2y ≤-2

=> -15 + 3y + 2y ≤-2

=> 5y ≤ 13

=> y  ≤  13/5

and

=> x ≥ 5-  13/5

=>  x ≥  12/5

The requried population increased by approximately 60.53%.

To find the absolute increase, we subtract the initial population from the final population:

Absolute increase = Final population - Initial population

Absolute increase = 6100 - 3800

Absolute increase = 2300

Therefore, the population increased by 2300 people.

To find the relative increase, we first calculate the percent change:

Percent change = (New value - Old value) / Old value x 100%

Percent change = (6100 - 3800) / 3800 x 100%

Percent change = 2300 / 3800 x 100%

Percent change = 60.53%

Therefore, the population increased by approximately 60.53%.

The values of the unknown in the figures are a = 40, b = 32 and c = 275

Figure (a)

A quadrilateral has a total angle measure of 360 degrees.

So, we have

90 - a + 92 + 128 + 90 = 360

Evaluate the like terms

-a = 360 - 400

So, we have

a = 40

Figure (b)

The total measure of angles on a line is 180 degrees.

So, we have the following

4b - 10 + 2b - 2 = 180

Evaluate the like terms

6b = 192

So, we have

b = 32

Figure (c)

The total measure of angles at a point is 360 degrees

So, we have the following

c + 19 + (94 - 28) = 360
