Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given details

STEP 2: Explain Tangent line

Tangent Lines:

The tangent line to a function f(x) is a line that touches the graph of the function at one specific point of tangency where it has the same slope as the function at that point.

If x = a is the point of tangency, the tangent line can be written in slope-intercept form as:

STEP 3: Find the tangent

We can first determine the slope of the tangent line by differentiating the function. Writing the function as:

We find the derivative using the chain rule:

At the point of tangency, the slope is

We can begin to write the equation of the tangent line in slope-intercept form

Substituting both coordinates of the point of tangency allows us to solve for the intercept:

Answer:

9

Step-by-step explanation:

Plug in 6 to x, since this is the x-value in the ordered pair.

\(3(6)+2y=36\\18+2y=36\\2y=18\\y=9\)

Answer:

(6, 9)

Step-by-step explanation:

3x + 2y = 36

Substitute 6 into the equation to get the output.

3(6) + 2y = 36

Multiply 3 and 6.

18 + 2y = 36

Subtract 18 from both sides.

2y = 18

Divide both sides by 2.

y = 9

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.

Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.

We have:

z₁ = 7(cos(577°) + i sin(577°))

Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.

From the given information, we have:

z₂ = 21(cos(-7°) + i sin(-77°))

To find the quotient, we divide z₁ by z₂:

z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]

Substituting the given values, we have:

z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]

= (7/21) * [cos(584°) + i sin(584°)]

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

The ratio of the surface area of the larger cylinder to the surface area of the smaller cylinder is 4:3, or 4/3.

To find the ratio of the surface areas of the two similar cylinders, we need to consider the ratio of their corresponding dimensions. Since the two cylinders are similar, their radii are proportional to their heights. Let's denote the height of the smaller cylinder as h1, the height of the larger cylinder as h2, the radius of the smaller cylinder as r1, and the radius of the larger cylinder as r2.

Given:

h1 = 15 inches

h2 = 20 inches

The ratio of the heights is:

h2 / h1 = 20 / 15 = 4 / 3

Answer:

± (1 ÷ 9)

Step-by-step explanation:

Data provided in the question

Since  3 is added to the absolute value and -9

The result is 4

Now this information should be transformed in a mathematical equation

Let us assume be x so the product of the number and -9 be -9x

Fo rthe absolute value we use the mode. Thus the required expression is:

3 + |-9x|

Given that the result is 4

So, it would be

3 + |-9x| = 4

Now Solving the above equation which is given below:

|-9x| = 4-3

|-9x| = 1

here we will remove the mode by introducing ± sign which is shown below:

-9x = ± 1

-9x = 1 or -9x = -1

x = -1/9

or

x = \(\frac{1}{9}\)

Therefore, the value of x is ± (1 ÷ 9).

Hello!

\(\large\boxed{a = 13m/s^{2}}\)

Use the equation F = m · a to solve where:

F = total force (N)

m = mass (kg)

a = acceleration (m/s²)

We are given the force and mass, so we can plug these values into the equation to solve.

However, mass is used in kilograms, so we must convert from grams to kilograms:

1 kg = 1000 grams

Convert using dimensional analysis or proportions:

\(500 g* \frac{1 kg}{1000g} = 0.5kg\)

Plug in the force and mass to solve:

6.5 = 0.5(a)

Divide both sides by 0.5 (Multiply by 2)

a = 13 m/s²

OKOKOKOKOKOKOKOKOOKOOKO

Step-by-step explanation:

The expression you provided involves taking the square root of a negative number, which results in an imaginary number. In standard real number arithmetic, the square root of a negative number is undefined. However, in the realm of complex numbers, we can define a square root of negative numbers using the imaginary unit "i," where i is defined as the square root of -1.

Let's break down the expression step by step:

√(-25) / √9

The square root of -25 can be written as √(-1 * 25), which can further be simplified as √(-1) * √25.

√(-1) is equal to "i," and the square root of 25 is 5.

So, the expression becomes:

i * 5 / √9

The square root of 9 is 3.

Now, we can simplify further:

i * 5 / 3

Thus, the simplified expression is (5i) / 3, where "i" represents the imaginary unit.

A) All x- and y-intercepts include the following:

x-intercepts: none.

y-intercept: 1.

B) The equation for vertical asymptote is x = 4 and the equation for horizontal asymptote is y = 0.

C) The domain and range of f are:

Domain = [-∞, 4) U [4, ∞]

Range = [0, ∞]

In Mathematics, the x-intercept is the point at which the graph of a function crosses or touches the x-coordinate and the y-value or value of "y" is equal to zero (0).

Part A.

Based on the graph of this rational function, the x-intercept and y-intercept include the following:

x-intercept: none.

y-intercept: 1.

Part B.

An equation that represents the vertical asymptote is x = 4 while the equation represents the horizontal asymptote is y = 0 because the line does not cross those points.

Part C.

By critically observing the graph of this rational function, we can logically deduce the following domain and range:

Domain = [-∞, 4) U [4, ∞] or {x|x ≠ 4}.

Range = [0, ∞] or {y|y ≥ 0}.

The segment lengths are given as follows:

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

The theorem is expressed as follows:

c² = a² + b².

In which:

Considering the geometric mean theorem, the triangle has bases of 7 and 14 - 7 = 7, hence the altitude BD is given as follows:

BD² = 7 x 7

BD² = 7²

BD = 7.

The segment BC is the hypotenuse of a right triangle of two sides with length 7, hence:

(BC)² = 7² + 7²

Step-by-step explanation:

Just use a calculator.

Answer: 4.5 litres

Step-by-step explanation:

If 1.5 liters of red paint is mixed with white paint to make 6 liters of pink paint, then the ratio of red paint to the total mixture is 1.5/6 = 0.25.

Since the pink paint is made by mixing red paint with white paint, the ratio of white paint to the total mixture is 1 - 0.25 = 0.75.

Therefore, to find the amount of white paint needed, we can set up the following proportion:

1.5/0.25 = x/0.75

Solving for x, we get:

x = 0.75 * 1.5 / 0.25 = 4.5

So, 4.5 liters of white paint is needed to make 6 liters of pink paint.

Hi!

If 6 liters were to be made, and 1.5 liters of red is needed, then we would subtract 1.5 from 6 to get your final answer
6 - 1.5 = 4.5.
So, 4.5 liters of white will be needed to make 6 liters of paint.

The lengths of the three sides of the triangle are 10, 25 and 25 feet

The perimeter of a shape is the sum of the side lengths of the shape

For all regular quadrilaterals, you add up the side lengths to determine the perimeter

The given parameters about the triangles are given as

Perimeter = 60 feet

Middle length = 5 feet greater than twice the smallest side

Longest side= 5 feet less than 3 times the smallest side.

Represent the lengths with x, y and z

So, we have

y = 5 + 2x

z = 3x - 5

The perimeter is the sum of the side lengths

So, we have

P = x + y + z

This gives

P = x + 5 + 2x + 3x - 5

Evaluate the like terms

P = 6x

Recall that

Perimeter = 60 feet

So, we have

6x = 60

Divide by 6

x = 10

Recall that

y = 5 + 2x

z = 3x - 5

So, we have

y = 5 + 2 x 10 = 25

z = 3 x 10 - 5 = 25

Hence, the lengths of the three sides of the triangle are 10, 25 and 25 feet

Answer:

For \(x = -2\)

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

\(ax^{2} + bx + c, a\neq0\).

This polynomial has roots \(x_{1}, x_{2}\) such that \(ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})\), given by the following formulas:

\(x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}\)

\(x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}\)

\(\Delta = b^{2} - 4ac\)

In this question:

\(f(x) = x^2 - 2x\)

\(g(x) = 6x + 4\)

\(f(x) + g(x) = (f+g)(x)  = x^2 - 2x + 6x + 4 = x^2 + 4x + 4\)

Which is a value of x does (f+g)(x) =0

\(x^2 + 4x + 4\)

Quadratic equation with \(a = 1, b = 4, c = 4\)

So

\(\Delta = 4^{2} - 4*1*4 = 0\)

\(x_{1} = \frac{-4 + \sqrt{0}}{2} = -2\)

\(x_{2} = \frac{-4 - \sqrt{0}}{2} = -2\)

For \(x = -2\)
