Step-by-step explanation:

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

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 required equation of line is y + 2x +7 =0 .

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

The graph of the function y = - 2x + 6 is plotted and attached.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the following equation of line -

y = - 2x + 6

Given is the following equation of line as -

y = - 2x + 6

The slope of the line would be [- 2] and the [y] intercept would be [6].

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

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)

    100         :   1

    250         :  2.5

     78.2        :   782

     123.9       :  1.239

The value that goes next to y is,

y: y×(1/100)

Therefore, x=y×(1/100)

The equation for the proportional relationship is  x=y×(1/100)

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
