What is a sequence?

A sequence is a mathematical term that refers to the succession of numbers or other mathematical objects related to each other, which is characterized by taking into account the relative position of each number with respect to the previous one.

According to the above, it can be inferred that from the following sequence:

2, 4, 6, ...

The operation that is defining the sequence is:

0 + 2 = 2

2 + 2 = 4

4 + 2 = 6

Step-by-step explanation:

The equation of the parabola with its focus at (–7,6) and its directrix at y = 4 will be (x + 7)² + 5.

By drawing the graph, it's can be depicted that the equation in this scenario is x² + 14x + 54.

Complete the square on the expression. This will be done by adding 49. This will be:

= x² + 14x + 7² + 54 - 49

= (x + 7)² + 5

Therefore, the equation of the parabola with its focus at (–7,6) and its directrix at y = 4 will be (x + 7)² + 5.

Step-by-step explanation:

just divide both sides by 3.14 yes

The radius of the circle is 12 inches.

Radius is the distance from the center of the circle to any point on its circumference, which means the line segment that connects the center of a circle to any point on its circumference is called the radius.

Given that the circumference of a circle is 75 inches we need to find the radius,

So,

C = π × diameter

75 = 3.14 × d

d = 23.88

∵ d = 2r

∴ r = 23.88/2

r = 11.94

r ≈ 12

Hence the radius of the circle is 12 inches.

The number of rows in the arena is 26

The hockey arena illustrates an arithmetic sequence, and it has the following parameters:

The number of rows (i.e. the number of terms) is calculated using:

[tex]S_n = \frac{n}{2}(2a + (n -1) * d)[/tex]

So,we have:

[tex]10920 = \frac{n}{2}(2 * 220 + (n -1) * 16)[/tex]

Evaluate the terms and factors

[tex]21840 = n(440 + 16n -16)[/tex]

Evaluate the like terms

21840 = n(424+ 16n)

Expand

21840 = 424n + 16n^2

Rewrite as:

16n^2 + 424n - 21840 = 0

Using a graphical tool, we have:

n = 26

Hence, the number of rows in the arena is 26

The equation of the circle with the new point will be x² + ( y - 2 )² = 16.

The circle is defined as the locus of the point traces around a fixed point called the centre and is equidistant from the outer trace.

Given that:-

The equation of the circle will be formed as:-

We know that the general form of the circle is given as

( x - h )² + ( y - k )² = r²,

where ( h, k ) is the centre and r is the radius. When the circle is shifted 2 units up it means that now its centre will be ( 0, 2). So the equation will be:-

x² + ( y - 2 )² = 16

Therefore the equation of the circle with the new point will be x² + ( y - 2 )² = 16.

The equation of the exponential model is f(x) = 3 * 0.2^x

The table of data is given as:

x(-2,-1,0,1,2)

f(x)(71,13,3,0.6,0.1)

An exponential model is represented as:

f(x) = ab^x

When x= 0 and f(x) = 3;

We have:

ab^0 = 3

This gives

a = 3

When x= 1 and f(x) = 0.6

We have:

ab^1 = 0.6

This gives

ab = 0.6

Substitute 3 for a

3b = 0.6

Divide both sides by 3

b = 0.2

Substitute b = 0.2 and a =3 in f(x) = ab^x

f(x) = 3 * 0.2^x

Hence, the equation of the exponential model is f(x) = 3 * 0.2^x
