Step-by-step explanation:

Background knowledge about the sequence function

A sequence is defined as the function whose domain is the set of natural numbers (counting numbers).

1,        2,        3,       4,     ....        n,   ....  

↓

a₁,       a₂,      a₃,      a₄,    ....       aₙ,   ....

Here,

1 gets mapped onto a₁,

2 gets mapped onto a₂, and so on

The numbers a₁,       a₂,      a₃,      a₄,    ....       aₙ,   .... are the terms of the sequence.

The number aₙ is the nth term of a sequence.

And the sequence function is denoted by {aₙ}.

Given the sequence

3, 9, 15, 21, ...

Here,

a₁ = 3 is the first term

a₂ = 9 is the second term

Thus, the ordered pair to represent the second term as an ordered pair is:

I used the Desmos Polar graph and got the correct answer!!!

A point C reflected about polar-axis has coordinates [tex](5,-\frac{7\pi}{6} )[/tex]

For given question,

We have been given four points.

[tex]A=(5,\frac{\pi}{6} ), B=(5,\frac{5\pi}{6} ),C=(5,\frac{7\pi}{6} ),D=(5,\frac{11\pi}{6} )[/tex]

If we plot the above points on the polar coordinate plane then it would be as shown below.

We need to find the point having coordinates [tex](5,-\frac{7\pi}{6} )[/tex]

If we reflect a point [tex]C(5,\frac{7\pi}{6} )[/tex] about polar-axis then the coordinates of the reflected point would be [tex](5,-\frac{7\pi}{6} )[/tex]

Therefore, point C reflected about polar-axis has coordinates [tex](5,-\frac{7\pi}{6} )[/tex]

Answer:

y = 1/4x-1

Step-by-step explanation:

Ok first, you need to find the slope:

0+2 = 2=1

4+4 = 8=4

Slope: 1/4

y=1/4x+b

Now you need to find the y intercept which is b. For that you can take a coordinate pair and substitute it in the equation to find b.

I will use (4,0)

0=1/4 X 4 + b

0=x+b

minus x on both sides. x=1

-1=b

An equation of the line that passes through the pair of points

(- 4, - 2), (4, 0) is  y + 2 = (1/4)(x + 4).

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A  line that passes through the pair of points. (−4, −2), (4, 0).

We also know slope(m) = (y₂ - y₁)/(x₂ - x₁) = (0 + 2)/(4 + 4) = 1/4.

So, the equation of a line in point-slope form is y - y₁ = m(x - x₁).

∴ y + 2 = (1/4)(x + 4).

Answer:

71.915

Step-by-step explanation:

3.785= how many liters that are in a gallon X 19= gallons of gas needed to fill the tank

The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

Given that,

The amount of fuel Paul's car holds = 19 gallons.

We know that,

1 gallon = 3.78541 liter

Multiply both sides by 19

19 gallon = 71.92 liter.

Hence "The number of liters in 1 gallon is 3.78541 therefore,71.92 liters Paul needs to fill in his tank".

1/4 × 6 × (5a) = 12

a= 4/5

Step-by-step explanation:

The area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2) with the coordinate axes is 10. The constant (a) of the function is 4.

The triangle formed by the parabola has a base equal to the distance between the points where the graph touches the x-axis and height (h) is the point where the graph touches the y-axis.

The points on the x-axis are the roots of the quadratic equation:

a(x-3)(x+2)=0

(x-3)(x+2)=0

x - 3 = 0

x = 3

or

x + 2 = 0

x = -2

So, the base is the distance between (-2,0) and (3,0).

Since they are in the same coordinate, the distance here;

b = 3 - (-2)

b = 5

The area of the triangle is 10. So

5a = 10 x 2

a = 4

The constant (a) of the function y = a(x-3)(x+2) is 4.

The airplane needs no more than 3 tanks of fuel to travel no more than 7,800 miles. The solution represents the maximum number of tanks of fuel that Neil's airplane can use to travel no more than 7,800 miles without running out of fuel.

What is inequality?

In mathematics, an inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions.

Part A:

Let x be the number of tanks of fuel needed to travel no more than 7,800 miles. Since the airplane needs a full tank of fuel to travel 2,600 miles, we can write the inequality:

x(2,600) ≤ 7,800

This inequality states that the total distance traveled (2,600 miles per tank) multiplied by the number of tanks (x) must be less than or equal to the maximum distance of 7,800 miles.

Part B:

To solve the inequality, we can divide both sides by 2,600:

x ≤ 3

Hence, the airplane needs no more than 3 tanks of fuel to travel no more than 7,800 miles. The solution represents the maximum number of tanks of fuel that Neil's airplane can use to travel no more than 7,800 miles without running out of fuel.

Answer:

Taylor will charge more by $15

Step-by-step explanation:

Given

Taylor

First Hour = $15

Hourly Rate = $10

Lucy:

[tex]f(x) = \left \{ {{20x,\ 0 \le \ x \ \le 2} \atop {10x, x>2}} \right.[/tex]

For a dog walk of 2.5 hours.

Taylor's charges is:

[tex]Charges = First\ Hour + Hourly\ Rate * 2.5[/tex]

[tex]Charges = \$15 + \$10 * 2.5[/tex]

[tex]Charges = \$15 + \$25[/tex]

[tex]Charges = \$40[/tex]

Lucy's charges is:

Here, we consider

[tex]f(x) = 10x[/tex] Because [tex]x > 2[/tex]

i.e 2.5 > 2

So, Lucy's charges is:

[tex]Charges = 10 * \$2.5[/tex]

[tex]Charges = \$25[/tex]

By comparison;

Taylor will charge more by $15

The difference is calculated by:

[tex]Difference = \$40 - \$25[/tex]
