Enter a recursive rule for the geometric sequence. 10, −80, 640, −5120, ...

a(1)=
a(n)=

Answers

The recursive formula would be:
[tex]a_1=10 \\a_{n}=a_{n-1} \times (-8)[/tex]

This is because the first term, a₁, is 10. A recursive rule is dependent upon the term before it (a(n-1)) and the common ratio. The common ratio, or the number that each term is multiplied by, is -8.

Answer:

The value is:

a(1)=10 and a(n)=(-8)×a(n-1)

Step-by-step explanation:

We are given a sequence as:

10, -80 , 640 , -5120 ,.........

since by looking at the sequence we could see that it is a geometric progression (G.P.) with common ratio -8.

Also a(1) denotes the first term of the sequence and a(n) denotes the nth term of the sequence.

a(1)=10

Also a(n)=(-8)×a(n-1)

since a(1)=10

a(2)=(-8)×10=-80

a(3)=(-8)×(-80)=640

a(4)=(-8)×640=-5120

and so on.

Hence the answer is:

a(1)=10 and a(n)=(-8)×a(n-1)

To find the number less than x you have to subtract with the larger number .
8.0-2.5 = 5.5
Find the number that greater than x you have to add those to number
8.0+2.5 = 10.5
So
5.5

8<x<10.5
because it is longer than 8 but if you add the 2.5 to it it is shorter than 10.5

Must a decimal divisor and a decimal dividend have the same number of decimal places in order to have a whole number quotient? write a division equation using two decimal numbers to support your answer.

Answers

No.

0.5/0.125 = 4 . . . . . 1 dp divided by 3 dp

Answer:

NO. They do not have to be equal

Step-by-step explanation:

A whole number takes place when two conditions are satisfied:

1. The numerator or the dividend is greater than the divisor.

For example, when you divide 0.1 by 0.002.

The dividend 0.1 is greater than 0.002

2. The divisor is small than the dividend.

This rule is the same as one above.

for example:

the quotient x is given by [tex]\frac{1}{0.25}\\ = 4[/tex]

there was a warning of volcano eruption in Kilauea in Hawaii. from September 7th to September 8th 2014, the flow advanced about 3/8 kilometers towards the edge of highway 130. the distance (in kilimeters) between the edge of the lava flow and the highway 130 can be given by the function f(t)=6-3/8t where t is the number of days since September 9, 2014. what is the input variables? What are the units of the input variable?

Answers

Answer: The input variable is the number of days since September 9th.. The unit for the input variable is single days.

When you are given an equation, there is an input and an output. In this case, you put in the number of days and the output is the distance between the lava and the road.

If you make a chart of the inputs and outputs, you will see that the lava is getting closer to the road.

To solve this problem, we use the formula given, which states that SA=6s^2, where SA is the surface area and s is the edge length of the cube.

We were given that the edge length of the cube is 3 1/2 feet, and that we are trying to find the surface area of the cube, so let’s plug these values into our formula.

SA=6(3 1/2)^2
To make this easier to simplify, we are going to replace 3 1/2 with its equal improper fraction, 7/2.
SA=6(7/2)^2
Now, following the order of operations, we are going to simplify what is inside the parenthesis by squaring it.
SA=6(49/4)
Now, we are going to multiply our last two terms together, to get:
SA= 294/4
This number simplifies to 147/2 when we divide both the numerator and denominator by their greatest common factor of 2.
However, the problem asks for your answer as a mixed number in simplest form, which we get when we divide out this improper fraction.
Your final answer is 73 1/2 ft^2.

Answers

Answer:
y = 7

Explanation:
The first given equation is:
y = x² - 3x + 7 ...........> equation I
The second given equation is:
y = 3x - 2 ..............> equation II

Substitute with equation I in equation II and solve for x as follows:
y = 3x - 2
x² - 3x + 7 = 3x - 2
x² - 3x + 7 - 3x + 2 = 0
x² - 6x + 9 = 0
(x-3)² = 0
This means that:
x = 3

Now, substitute with the value of x in equation II to get the y as follows:
y = 3x - 2
y = 3(3) - 2
y = 7

2.) (-19, 3), (7, 16)

Answers

To find the slope, use rise over run.

1) The difference between x values is 2. This is the run.
The difference between y values is 8. This is the rise.
8 over 2, or 8 divided by 2, is 4. The slope is 4.

1) The difference between x values is 26. This is the run.
The difference between y values is 13. This is the rise.
13 over 26, or 13 divided by 26, is 1/2. The slope is 1/2.

Jasmine has a piece of ceramic tile that is shaped as a parallelogram. What is the area of this parallelogram?
96 in²
288 in²
352 in²
384 in²

Answers

⓵ To calculate the area of a parallelogram, the formula is base times height, just like the formula for the area of a rectangle! Why? Because if you look closely, every parallelogram can be made into a rectangle just by moving one of the triangle parts of it.

⓶ Now that we know that the formula to calculate the area of a parallelogram is :
A = b × h

You need to find the numbers to replace the base and the height in the formula!

We already know that the height is : 12 in.

So we are left with a formula looking like this :

A = b × 12 in.

⓷ Now we need to find the base! To do so, you need to add the height of the rectangle (which is 8 in.) to the height of one of the triangle (which is 16 in.) :

8 in. + 16 in. = b

↓

8 in. + 16 in. = 24 in.

↓

24 in. = b

So we are left with a formula looking like this:

A = 24 in. × 12 in.

⓸ All there’s left to do now, is calculate the area of the parallelogram using the formula :

A = 24 in. × 12 in.

↓

24 in. × 12 in. = 288 in.²

↓

A = 288 in.²

So your final answer is : the area of this parallelogram is ↠ 288 in.²

I really hope this helped, if there’s anything just let me know! ☻

jamal purchased a boat for 7/10 of the asking price of $18,950. He had to pay 6.5% sales tax. What was the amount of Jamal's bill?

Answers

Hello,

Since Jamal is only paying for 7/10 of the asking price, we can multiply it by 0.7.

0.7 x 18950 = 13265

Now, we have to add on the tax, so we should multiply the new amount by 1.065.

13265 x 1.065 = 14127.23

Jamal's bill will be $14,127.23

Triangle ABC has vertices A(5, 3) , B(3, 7) , and C(1, 4) . Triangle ABC is dilated, and the vertices of the image are A′(2.5, 1.5) , B′(1.5, 3.5) , and C′(0.5, 2) . The center of dilation is the origin.

What is the scale factor of the dilation?

0.25

0.5

Answers

I believe the answer would be 0.5

Hope this helps ;}

Answer: The correct answer is (B) 0.5.

Step-by-step explanation: Given that A(5, 3) , B(3, 7) and C(1, 4) are the vertices of ΔABC and A′(2.5, 1.5) , B′(1.5, 3.5) and C′(0.5, 2) are the vertices of ΔA'B'C'.

We are to find the scale factor of the dilation of the centre of dilation is origin.

We know that the scale factor of dilation is given by the following formula:

[tex]S_c=\dfrac{\textup{length of a side of the dilated figure}}{\textup{length of the corresponding side of the original figure}}.[/tex]

We can calculate the lengths of the corresponding sides AB and A'B' of ΔABC and ΔA'B'C' respectively using distance formula as follows:

[tex]AB=\sqrt{(3-5)^2+(7-3)^2}=\sqrt{4+16}=\sqrt{20}=2\sqrt5,\\\\A'B'=\sqrt{(1.5-2.5)^2+(3.5-1.5)^2}=\sqrt{1+4}=\sqrt{5}.[/tex]

Therefore, the scale factor for the dilation is given by

[tex]S_c=\dfrac{A'B'}{AB}=\dfrac{\sqrt5}{2\sqrt5}=\dfrac{1}{2}=0.5.[/tex]

Thus, the required scale factor is (B) 0.5.

For the total length of the five rods in terms of a is L = 15a.

The formula for the Total Length of Five Rods

Certainly! To find a formula for the total length (L) of the five rods in terms of a, let's denote the lengths of the rods as a, 2a, 3a, 4a, and 5a (since there are five rods, each consecutive rod has a length that is one unit greater than the previous rod). So, the lengths of the rods are:

First rod: a

Second rod: 2a

Third rod: 3a

Fourth rod: 4a

Fifth rod: 5a

Now, to find the total length (L), add up the lengths of all the rods:

L = a + 2a + 3a + 4a + 5a

Combine like terms:

L = (1 + 2 + 3 + 4 + 5) · a

The sum of the first n natural numbers is given by the formula n(n + 1)/2, so in this case:

L = 5 · 6/2 · a

Simplify the expression:

L = 15a

So, the formula for the total length L in terms of a is L = 15a.

The complete question is:
