The x-coordinate of the point where the line tangent to the curve is the x-axis is; x = -8

To get he x-coordinate of the point that the line tangent to the curve is the x-axis, what we will do is to equate the numerator of the derivative to zero.

Now, we are given the equation of the curve as;

y² - 6y - 9x² - 144x = 576.

We are told that It can be shown that;

dy/dx = 9(x + 8)/(y - 3)

From our earlier definition, the x-coordinate will be at;

9(x + 8) = 0

divide both sides by 9 to get;

x + 8 = 0

x = -8

The distance of the library from the community pool is given  as 4.4 km

We have to solve this problem with the use of the Pythagoras theorem.

The formula is given as

a² = b² + c²

The total distance flown would be represented by a = 10 kilometer

the distance for the courthouse would be given as 9 kilometers

When we put these values in the formula we would have

10² = a² + 9²

100 = a² + 81

a² = 100 - 81

a² = 19

a = √19

a = 4.4 km

Hence the calculated distance is given a 4.4 km from the library to pool.

Answer:

$36

Step-by-step explanation:

First, let us make an expression to solve this using the given information.

For that let the total cost be x.

Amount of the bill                     tip                     total cost

          100                 ⇒               20          ⇒           120

           30                  ⇒               20          ⇒            x

Accordingly,

100 ⇒ 120

30   ⇒  x

Use cross multiplication and solve for x.

100x = 120 × 30

100x = 3600

Divide both sides by 100.

x = $ 36

Using trigonometric ratio, the distance of the bird is 21.8m

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

To solve this problem, we have to use trigonometric ratio of SOHCAHTOA

Let's define the variables given;

Using Tangent of an angle;

tanθ = opposite / adjacent

tan 36 = x / 30

Cross multiply both sides and solve for x

30 tan36 = x

21.8 = x

The distance above the ground from the bird is 21.8 meter.

The volume of the jewelry box will be;

⇒ 343 inch³

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Edna bought a cube-shaped jewelry box that has 7-inch sides.

And, The volume of a cube with side s is s³.

Now,

Since, Edna bought a cube-shaped jewelry box that has 7-inch sides.

Hence, The volume of the jewelry box = 7³

                                                            = 7 × 7 × 7

                                                            = 343 inch³

Thus, The volume of the jewelry box will be;

The equation of asked line is y = x/3+3

An equation is a mathematical statement that shows that two mathematical expressions are equal.

The equation of a line passing through two points (x1, y1) and (x2, y2) is

y-y1 = (y2-y1)/(x2-x1)*(x-x1)

The two points are (6, 5) and (3, 1)

Equation =

y-5 = -4/-3*(x-6)

y-5 = 4/3*(x-6)

3y - 15 = x-6

3y = x+9

y = x/3+3

Hence, the required equation is y = x/3+3

Step-by-step explanation:

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

The total amount in the smaller feeder is 2 kg.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Chindi puts 2(3/5) kg of bird seed in his large feed.

This is 1(3/10) times as much bird seed as he puts in his smaller feeder.

The total amount is represented by 1.

Now,

1(3/10) = 2(3/5) kg

13/10 = 13/5 kg

Multiply both sides by 10/13

1 = 10/13 x 13/5 kg

1 = 2 kg

This means the total amount of seeds in the smaller feeder is 2 kg.

Thus,

The total amount in the smaller feeder is 2 kg.

The equation of line is y + 2x +7 =0 for the points (-5,3) and (0,-7).

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The given points are (-5, 3) and (0, -7).

To find the equation of line, use formula,

y - y₁ = m(x - x₁) where m = (y₂-y₁)/(x₂-x₁),

y - 3 = (-7 - 3)/(0-(-5)) (x - (-5))

y - 3 = -10 / 5 (x + 5)

y - 3 = -2 (x + 5)

y + 2x +7 =0

The new function rule is g(x) = 2x -3

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).

if f(x) = 2x, then f(x-4) = 2(x-4)

g(x) = f(x-4) + 5

substitute f(x-4) into g(x)

g(x) = 2(x-4) + 5

g(x) = 2x -8 + 5

g(x) = 2x - 3

In conclusion, the function rule g(x) is 2x - 3

The equation for the proportional relationship is x=y×(1/100) where x represents length in meters and y represents same length in centimeters.

The phrase proportionality refers to any relationship that always has the same ratio. The quantity of apples in a crop, for example, is proportionate to the number of trees in the orchard, with the ratio of proportionality being the average number of apples per tree.

In mathematics, two sequences of numbers, generally experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is known as the coefficient of proportionality or proportionality constant.

Given,

Length(cm): Length(m)
