Which formula can be used to describe the sequence?
-2/3, -4, -24, -144,...

Answers

Answer 1

The formula that describes the sequence given i.e. \(\frac{-2}{3}\),-4,-24,-144 (geometric sequence) is \((\frac{-2}{3} )(6)^{n-1}\)

Geometric progression:

A geometric progression or a geometric sequence is a series, in which each word is varied by another by a common ratio. When we multiply the previous term by a constant (which is non-zero), we get the following term in the sequence. It is symbolized by:

A, AR,\(AR^{2}\),\(AR^{3}\)...

Where A is the first term of the geometric sequence and R is the common ratio of the geometric sequence.

The general term of geometric sequence i.e. nth term =\(AR^{n-1}\)

Given that A= \(\frac{-2}{3}\) and R=6

As a result the general term of geometric sequence i.e. nth term =\((\frac{-2}{3} )(6)^{n-1}\)

Therefore,The formula that describes the geometric sequence given i.e. \(\frac{-2}{3}\),-4,-24,-144 is \((\frac{-2}{3} )(6)^{n-1}\)

What is the area of this rectangle? Rectangle with width 5.1 cm and height 11.2 cm. Responses 16.3 cm2

Answers

The area of a rectangle with a width of 5.1 cm and a height of 11.2 cm is 57.12 cm².

To find the area of a rectangle, we multiply its length by its width. In this case, the width is given as 5.1 cm and the height (or length) is given as 11.2 cm.

Area = length × width

Area = 11.2 cm × 5.1 cm

Calculating the product, we get:

Area = 57.12 cm²

Therefore, the area of the rectangle is 57.12 cm².

The correct answer is: 57.12 cm².

It is important to note that when calculating the area of a rectangle, we should always include the appropriate unit of measurement (in this case, cm²) to indicate that we are dealing with a two-dimensional measurement. The area represents the amount of space covered by the rectangle's surface.

So, the area of a rectangle with a width of 5.1 cm and a height of 11.2 cm is 57.12 cm².

What is the explicit formula for the geometric sequence: 4, 20, 100, 500, ... .

Answers

aₙ = 4 × 5⁽ⁿ ⁻ ¹⁾ is the explicit formula for the geometric sequence: 4, 20, 100, 500.

How to determine the geometric explicit formula of sequence?

A geometric progression is simply a sequence of non-zero numbers, every term after the first can be determine by multiplying the previous number by a common ratio.

The nth term of a geometric sequence is expressed as;

aₙ = a₁ × r⁽ⁿ ⁻ ¹⁾

Where a₁ is the first term, r is the common ratio and n is the number of terms.

Given the sequence in the question;

4, 20, 100, 500, ...

First determine the common ratio.

r = any term / previous term

r = 20/4

r = 5

Th first term in the sequence is 4.

Plug these into the geometric sequence formula and simply.

aₙ = a₁ × r⁽ⁿ ⁻ ¹⁾

aₙ = 4 × 5⁽ⁿ ⁻ ¹⁾

Therefore, the explicit formula for the sequence is aₙ = 4 × 5⁽ⁿ ⁻ ¹⁾

The coordinates of the focus of the parabola are (3, 2)

What is the general equation of a parabola?

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix. The general equation of a parabola is -

y = a(x - h)² + k

We have the following equation of a parabola as -

f(x) = (1/4)(x - 3)² + 1

We can calculate the coordinates of the focus using the formula -

Focus : (h, k+ (1/4a))

[h] = 3

[k + (1/4a)] = 1 + (1/(4x 1/4) = 2

Therefore, the coordinates of the focus of the parabola are (3, 2)

Situation B: Suppose that 40% of Missourians favor increasing the minimum wage. Twelve Missourians are selected at random and asked whether they support the increase. Question B1: Find the probability that exactly three of the twelve support the increase.

Answers

Answer:

14.19% probability that exactly three of the twelve support the increase.

Step-by-step explanation:

For each Missourian, there are only two possible outcomes. Either they support the increase, or they do not. The probability of a Missourian supporting the increase is independent of other Missourians. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

40% of Missourians favor increasing the minimum wage.

This means that \(p = 0.4\)

Twelve Missourians are selected at random and asked whether they support the increase.

This means that \(n = 12\)

Find the probability that exactly three of the twelve support the increase.

This is P(X = 3).

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 3) = C_{12,3}.(0.4)^{3}.(0.6)^{9} = 0.1419\)

14.19% probability that exactly three of the twelve support the increase.

The sum of the ball's kinetic energy and potential energy remains the same. as the ball rolls from point A to E.( if there is no friction between the ball and the ground).

based on the law of mechanical energy's conservation, the sum of both kinetic and potential energies i.e. the total amount of mechanical energy remain conserved even in the absence of dissipative forces ( friction or air resistance) in a bound system.

the kinetic energy is when ball goes downward but potential energy decreases and reverse happens when ball goes up. but in these case, the sum energy would be constant one.

Ball Hall: 30 minutes
Lot A: 20 minutes

Answers

Using the lowest common factor of the shuttles' run times, they will depart again for the campus simultaneously at 10.25 A.M.

How is the time determined?

We can use the lowest common factor (LCM) of their run time to determine when they depart again for the campus.

The lowest common factor of 30 and 20 is 60 because both 30 and 20 can divide 60 evenly without a remainder, showing that it takes 60 minutes for the two shuttles to depart for the campus at the same time.

We can conclude that every 60 minutes or hour, the two shuttles simultaneously depart for the campus.  Every hour, the shuttle departing from Ball Hall completes 2 runs, while the shuttle departing from Lot A completes 3 runs.

Thus, using the lowest common factor, the next time both shuttles will depart for the campus at the same time is 10:25 A.M.

At a family reunion, there only blood relatives, consisting of children, parents, and grandparents, in attendance. There were 400 people total. There were twice as many parents as grandparents, and 50 more children than parents. How many children, parents, and Grandparents were in attendance?

Show up all steps please

Answers

There are 70 grandparents, 140 parents, and 190 children in attendance at the family reunion

Given data ,

Let's denote the number of grandparents as "g", the number of parents as "p", and the number of children as "c".

Given that there were 400 people total at the family reunion, we can write the equation:

g + p + c = 400

Now , there were twice as many parents as grandparents, so we can write:

p = 2g

And we are given that there were 50 more children than parents, so we can write:

c = p + 50

Now we can use the equations (1), (2), and (3) to solve for the values of g, p, and c.

On simplifying the equation , we get

g + 2g + (2g + 50) = 400

5g + 50 = 400

5g = 400 - 50

5g = 350

g = 350 / 5

g = 70

Now we can substitute the value of g into (2) to find the value of p:

p = 2g = 2 x 70 = 140

And we can substitute the value of p into (3) to find the value of c:

c = p + 50 = 140 + 50 = 190

Hence , there were 70 grandparents, 140 parents, and 190 children in attendance at the family reunion

1/3 2/5 3/4 4/5 is the answer

Answer:

\(\frac{1}{3}, \frac{2}{5} , \frac{3}{4} , \frac{4}{5}\)

Step-by-step explanation:

Start by making a common denominator. That way we can just compare the numerators of the fractions and easily order then from least to greatest. Start by finding the LCM(least-common-multiple) of the denominators.

The LCM of 3, 4, and 5, is 60.

So let's make each of the fractions have a denominator of 60.

Start with \(\frac{2}{5}\),

\(\frac{2}{5} =\frac{x}{60}\), no we have to solve for x, and since we multiply by 12 to get to 60 from 5, we multiply 2 by 12 as well.

So, \(x=24\).

Now do the same for each fraction.

\(\frac{1}{3} =\frac{x}{60}\), we multiply by 20, so \(x=20\)

\(\frac{4}{5} =\frac{x}{60}\), we multiply by 12, so \(x=48\)

\(\frac{3}{4}=\frac{x}{60}\), we multiply by 15, so \(x=45\)

So now are new fractions are \(\frac{24}{60} , \frac{20}{60} ,\frac{48}{60} , \frac{45}{60}\)

Now just order these like normal since they have a common denominator.

\(\frac{20}{60} ,\frac{24}{60} , \frac{45}{60} , \frac{48}{60}\)

Now revert them and make them there original values

Resolve 1-2x²/(x²+1)(x²+3x-2) to partial fraction ​

Answers

Sure, here's how to approach this question:

Let's first factorise the denominator of the given expression:

x²+1 can't be factorised any further, so let's work on the second factor:

x²+3x-2 = (x-1)(x+2)

Therefore, the denominator of the given expression becomes: (x²+1)(x-1)(x+2)

Now, let's assume that the expression is equal to a sum of two fractions:

1-2x²/(x²+1)(x-1)(x+2) = A/(x²+1) + B/(x-1) + C/(x+2)

Multiplying both sides by the denominator, we get:

1-2x² = A(x-1)(x+2) + B(x²+1)(x+2) + C(x²+1)(x-1)

Let's first put x=1 and solve for B:

1-2(1)² = B(1²+1)(1+2) + C(1²+1)(1-1)
1-2 = 4B
B = -1/2

Next, let's put x=-2 and solve for C:

1-2(-2)² = A(-2-1)(-2+2) + B((-2)²+1)((-2)+2) + C((-2)²+1)(-2-1)
1-8 = 15C
C = 7/-15

Finally, we can solve for A by putting x=0:

1-2(0)² = A(0-1)(0+2) + B((0)²+1)((0)+2) + C((0)²+1)(0-1)
1-0 = -2A + 2B - C
1 = -2A + 2(-1/2) - (7/15)
6/15 = -2A
A = -3/10

Therefore, the given expression can be resolved into partial fractions as:

1-2x²/(x²+1)(x-1)(x+2) = (-3/10)/(x²+1) + (-1/2)/(x-1) + (7/15)/(x+2)
