Write an explicit formula for each sequence. Then generate the first five terms. a₁ = 10, r=-1

Answers

The explicit formula for the nth term is a(n) = 10 . (-1)ⁿ⁻¹, while the first five terms are 10, -10, 10, -10, 10

In a geometric sequence, the next term is obtained by multiplying the previous term by a common ratio, usually denoted as r.

The general formula of the nth term of a geometric sequence is:

a(n) = a₁ . r^(n-1)

Here a₁ refers to the first term and r to the ratio.

In the problem, the given parameters are:

a₁ = 10, r = -1

Substitute these into the general formula, we get:

a(n) = 10 . (-1)ⁿ⁻¹

Notice that

(-1)ⁿ⁻¹ = -1  if n-1 is an odd number, or if n is an even number

(-1)ⁿ⁻¹ = 1   if n-1 is an even number, or if n is an odd number

Therefore, the first five terms are: 10, -10, 10, -10, 10

What is the nth term rule for this
sequence

Answers

The nth term of the given quadratic sequence begins 8, 11, 16, 23, 32, = n² + 7.

What is quadratic sequence?

Quadratic sequences are those that contain a word. They are distinguished by the fact that the first differences between terms really aren't equal, but really the second differences between terms remain equal.

What is a quadratic sequence's rule?

The difference between each term inside a quadratic series is not equal, but the second difference between every term is equal.

How can you tell whether a sequence is straight or quadratic?

A linear sequence is a number pattern that increases or lowers by the same amount each time. The common difference is the amount by which it increases or drops. Quadratic sequence: The difference between every term increases or decreases at a steady rate in quadratic sequence.

According to the given data:

Given:

8, 11, 16, 23, 32,

The nth rule is:

n² = 1² , 2², 3², 4² , 5²

n² = 1 , 4 , 9 , 16 , 25

Subtracting the equation:

8 , 11 , 16 , 23,  32

1 , 4, 9 , 16 , 25

we get:

7, 7, 7, 7

So that the nth term of the given quadratic sequence begins

8, 11, 16, 23, 32, = n² + 7.

b)

don't get confused.

the chart says temperatures at midday.

6 hours later IS 6pm.

the temperature in Kiev raises during that time from 1° up by 6°.

that means the temperature there is then 1 + 6 = 7° C at 6 pm.

Answer:

a. 9 °C

b. 7°C

Step-by-step explanation:

a. Difference, Rome and Oslo

→Rome: 11°C

→Oslo: 2°C

11°C- 2°C = 9°C

b. Kiev

The chart shows temperatures at midday (12pm). After 6 hours it's 6 pm.

→Kiev 1°C

→Temperature will rise 6°C

1°C + 6 °C = 7°C

At 6pm, the temperature in Kiev will be 7°C.

What is the definition of a triangle?A triangle is a three-sided polygon with three edges.It is a basic geometric shape.Triangle ABC is a three-vertical triangle with the letters A, B, and C.In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.

So,

The formula sides of the triangle: √(x₂−x₁)²+(y₂−y₁)²

Filling the values in the formula, we obtain:

= √(0-(-1))²+(3−2)²=  11.8 units

Then, the side of the triangle will be: 11.8 units

Since ΔABC is congruent to ΔHJI, then, the measure of HI will also be 11.8 units under the CPCT condition.

Therefore, the measures of HI will be 11.8 units under the Corresponding parts of the congruent triangles (CPCT) condition.

Determine whether the given measures define 0,1,2 , or infinitely many triangles. Justify your answers.
a=25, b=21, m

Answers

We can form an endless number of triangles when you are given two sides and no measurement of angle i.e a = 25 , b = 21

For Example -

We can chose the value of angle from 0-360 degrees with side length a = 25 and b =21, how many different triangles are possible to create?

Create one of the triangles with a protractor having the side lengths a = 25 m and b = 21 m and angle 12° and third side can be adjusted to your preferred length. You have built a triangle.

Similarly by changing the length of the third side and measure of the angle we will get an entirely new triangle.

It's important to notice that you choose the side lengths and angle. This suggests that you might make a different decision. By employing the same angles, you were able to make an infinite number of different triangles.

Therefore, with simply the measurements of one angle and a side length, we can create an endless number of triangles.

Answers

The length of the given rectangle is 9.

According to the statement

We have to find that the length of the rectangle.

So, For this purpose, we know that the

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel.

From the given information:

The width of a rectangle is 8 units less than the length. The area of the rectangle is 9 units

Then

Let the Length of the rectangle = x

Let the width of the rectangle = x-8

Area of the rectangle = L*B

Then

L*B = 9

x(x-8) = 9

x^2 -8x -9 = 0

x^2 -9x + 1x -9 = 0

x(x-9) +(x-9) = 0

(x+1) (x-9) = 0

here x = -1 and then x = 9.

Here neglect x  = -1 then

A bicycle has tires with a diameter of 26 inches. Find the radius and circumference of a tire. Round to the nearest hundredth, if necessary.

Answers

A circle is a curve sketched out by a point moving in a plane. The radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.

What is a circle?

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.

Given that diameter of the circle is 26 inches. Therefore, the radius and the circumference of the circle can be written as,

Diameter of circle = 2 × (Radius of the circle)

Radius of the circle= Diameter of circle / 2

Radius of the circle = 26 inches / 2

Radius of the circle = 13 inches

Circumference of circle = 2 × π × (Radius of the circle)

                                        = 2 × π × 13 inches

                                        = 26π inches

                                        = 81.6814 inches

Hence, the radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.

Find the coordinates of point P on →AB that partitions the segment into the given ratio AP to PB .
b. A(0,0), B(-15,0), 2 to 3

Answers

The line segment AB is divided at point P, which has coordinates P(0,-7.5)

A line segment is a section of a line that connects two locations to create a straight line or we can say that is connects two distinct points together to form a single line. It is extendable to either side.

Given are,

A line segment AB with coordinates of A(0,0 ) and B(-15,0) respectively

Two minor line segments, AP and PB, are created from the line segment AB by the provided point P

We must determine the dividing point's coordinates, or P.

We'll apply the formula provided,

The coordinates of the point P are given by  = ([tex]\frac{x1+x2}{2}[/tex],[tex]\frac{y1+y2}{2}[/tex] )

Now, x1 = 0, x2 = 0, y1 = -15, y2 = 0

Putting values in the formula, we get

([tex]\frac{0+0}{2}[/tex], [tex]\frac{0-15}{2}[/tex])

(0,-7.5)

Hence, the point P which partitions the line segment AB have coordinates as P(0,-7.5)
