Answer:

Rule is 4(5)^(n-1).

a7 = 62500.

Step-by-step explanation:

This is a geometric sequence with a1 = 4 and r = 20/4 = 5.

a7 is 4(5)^(7-1)

= 4 * 5^6

= 62500.

the general form of the given sequence is a(n) = 4 * 5ⁿ⁻¹ and a(7) is 62500.

A geometric sequence is a sequence of numbers that follows a pattern where the next term is found by multiplying by a constant called the common ratio, r.

Given a sequence  4, 20, 100, 500, ...

From the general formula of the nth term of the geometric sequence:

a(n) = arⁿ⁻¹

where,

a is the first term

r = ratio of two subsequent terms

in our case

a = 4

r = 20/4 = 5

thus, the general form of the given sequence

a(n) = 4 * 5ⁿ⁻¹

To find: a(7)

a(7) = 4 * 5⁶

a(7) = 62500

therefore, the general form of the given sequence is a(n) = 4 * 5ⁿ⁻¹ and a(7) is 62500.

Answer:

How can Mass and Speed Influence KE?

The goal of this experiment was to determine how mass and speed influence KE. This is significant because you would know whether to add more or less mass/speed if you were in a position where you required something to move higher. We filled the bean bag with a set amount of water, then dropped it to see how much mass it had. After that, you kept track of how high the bean bag went. The same thing happened with the speed, but the amount of liquid in the bottle was the same; it was just dropped from different heights. My theory is that the KE will increase as mass increases. This is also true of speed; if the bean bag is dropped from a higher altitude, it will launch farther than before.

The data I gathered in the lab confirmed my hypothesis. When the bottle's height was increased, the bean bag rose higher than before. I also tested four different masses: 0.125 kilograms, 0.250 kilograms, 0.375 kilograms, and 0.500 kilograms. The bean bag rose higher each time it was placed on a greater bulk.

On the speed test, the bean bag would frequently go higher than the bottle drop point, but not always. Furthermore, when it was dropped from the same height each time, the results differed significantly, for example, when it was dropped from 1.28, the results were 1.14, 1.30, and 1.30. Mass, on the other hand, was all in the same number range, with the exception that the numbers were somewhat different.

I used the calculations KE= 12 mv2 and Ht v2/2g. The initial step was to compute an object's kinetic energy, using the formula m=mass v=speed. The second was to determine the height at which I needed to drop something in order to reach a specific speed, where Ht=Height and g=Gravitational Acceleration of 9.8 m/s2.

I utilized these to create tables that depicted relationships between various variables, such as mass and KE or speed and height. My data kept increasing the entire time I was conducting the lab; when there was more mass/speed, the table had greater numbers.

This proves that my first theory was correct: as m/s increases, KE increases accordingly because they are all linear. When the bean bag height exceeded the water bottle drop mark, I was taken aback.

To summarize, my theory was supported by my data. When more mass or speed was introduced, the data values increased. This means that if I wanted more kinetic energy for something, I'd know to increase the mass or the speed of the object that was supplying the energy.

This hypothesis is valid because when you have greater mass, you also have more energy. So, if you drop a baseball, it isn't very heavy, so it will only propel the bean bag a short distance. However, because a bowling ball is quite heavy and has a lot of energy when it falls, it would force the bean bag to fly very high.

To improve this experiment, I would create the lever from a smoother material so that energy is not lost due to friction from the wood rubbing together. Perhaps a scanner or video camera to better document how far the bean bag traveled. All of these would aid the lab in obtaining more precise results, and they might perhaps be used in the future.

Hi! I'm happy to help!

To solve this, we need to first find how much the car value decreased.

The car started at $32,000, but dropped down to $6,300. To find the value drop, we use subtraction.

$32,000-$6300

$25,700

Now we know that his car value dropped $25,700 in value over the course of 3 years. Now we need to figure out how much value it dropped per year. To do this, we split the money into 3 years.

$25,700÷3

$8,566.6666666...

We can round this to $8,567

On average, his car lost $8,567 in value, per year. Now, we need to find how much value his car had after one year in order to get our integer. (a fraction of 2 whole numbers)

$32,000-$8,567

$23,433

Now that we know what his can was worth after one year, we can say that his can was worth $23,433 out of the $32,000 originally was worth. Out of can mean division, or fraction, and because these are both whole numbers, and integer. This is our integer:

[tex]\frac{23433}{32000}[/tex]

Since we cannot simplify it, this is our integer that represents the average decrease in value per year.

Answer:

Chim is 34 years old, and Jared is 8 years old.

Step-by-step explanation:

Let c be Chim's age and j be Jared's age.

Chim's age after five years (c + 5)

is 3 times Jared's age after five years (3 * (j+5) )

#1: c + 5 = 3(j+5)

We can add Chim's age and Jared's age to get 42 (the "sum"):

#2: c + j = 42

This is a system of equations that we can solve through substitution:

c + 5 = 3(j+5)

c + j = 42

In Equation #2, we can subtract j from both sides:

c = 42 - j

Then replace c with 42 - j in the first equation

(42 - j) + 5 = 3(j+5)

47 - j = 3j + 15

32 = 4j

j = 32/4 = 8

Plug j = 8 into the second equation, then solve for c.

c + 8 = 42

c = 42 - 8 = 34

c = 34, j = 8

Check our work by plugging in c = 34 and j = 8 into the first equation:

34 + 5 = 3(8+5)

39 = 3*13

39 = 39

Plug c and j into the second equation:

34 + 8 = 42

42 = 42

Chim is 34 years old, Jared is 8 years old.

Answer:

BD measures 20 units.

Step-by-step explanation:

We are given that Point C is on the line segment BD, where:

[tex]BD = 5x, BC = 4x \text{ and } CD = 4[/tex]

And we want to determine the numerical length of BD.

Since C is somewhere on BD, BD is the sum of BC and CD:

[tex]\displaystyle BD = BC + CD[/tex]

Substitute:

[tex](5x) = (4x) + (4)[/tex]

Solve for x. Subtract:

[tex]x = 4[/tex]

Hence, the value of x is 4.

BD is given by 5x. Therefore:

[tex]BD = 5(4) = 20\text{ units}[/tex]

In conclusion, BD measures 20 units.

To find,

The constant term.

Solution,

We have,

An expression, [tex]9x^3 + 4x^2 + 7x + 6[/tex]

The term that doesn't have any variable is the constant term of an expression.

The coefficient of [tex]x^3[/tex] is 9.

The coefficient of [tex]x^2[/tex] is 4.

The coefficient of [tex]x[/tex] is 7.

The constant term is 6 as it doesn't contain any variable.

Hence, the constant term is [tex]6[/tex].

Answer:

5w³

Step-by-step explanation:

To solve this, we can list the factors of each number and see which are common

25w⁵: separate this into 25 and w⁵ as one is a variable and one is not, so this will enable easier factorization. It is perfectly fine to separate these as these are multiplied by each other. For example, 5 is a factor of 25 but not of w⁵, but we can still factor 5 from 25w⁵ to get 5 (5w⁵)

factors of 25:

1, 5, 25

factors of w⁵:

1, w, w², w³, w⁴, w⁵

We know the factors of w⁵ because anything multiplied by 1 is equal to itself, w * w⁴ = w⁵, and w²*w³ = w⁵ due to exponent rules

Next,

factors of 5:

1, 5

factors of w⁴:

1, w, w², w³, w⁴

Finally,

factors of 15:

1, 3, 5, 15

factors of w³:

1, w, w², w³

For the constants, the greatest common factor is 5, and for the variables, the greatest common factor is w³

Because each value has both a constant and variable, we can use these two numbers to factor this out as

5w³(5w²+w + 3)

Answer:

A. mB = 40°

Step-by-step explanation:

In geometry, congruent figures are identical in form, coinciding exactly when superimposed.

From the diagram,

<CAB = 80°; <EFG = 40° and <FGE = 60°

From triangle ️ EFG,

<GEF + <EFG + <FGE = 180°

》<GEF = 180° - (<EFG + <FGE)

<GEF = 180° - (40° + 60°)

<GEF = 180° - 100°

<GEF = 80°

》<GEF = <CAB = 80°

Also,

》<ACB = <EGF = 60°

<ABC = <EFG = 40°

Answer:

-9 3/4

Step-by-step explanation:

FG = GH

9x+15 = 5x+4

Subtract 5x from each side

9x+15-5x = 5x+4-5x

4x+15 = 4

Subtract 15 from each side

4x+15-15 = 4-15

4x = -11

Divide by 4

4x/4 = -11/4

x = -11/4

FG = 9x+15

FG = 9*(-11/4) +15

  = -99/4+15

    -99/4 + 60/4
