Las soluciones para los dos primeros ejercicios son:

Vamos a ver la primer operacion, está es:

10² + 6³ - [4*(5 - 2)]²

Primero se resuelve lo que esta adentro del parentesis, en este caso:

5 - 2 = 3

Reemplazamos eso:

10² + 6³ - [4*(3)]²

Luego se resuelve lo que está dentro de los corchets:

4*3 = 12

Reempazamos eso para obtener:

10² + 6³ - [12]²

Ahora podemos resolver los exponentes, recordar que el exponente nos dice cuantas veces debemos multiplicar un número por si mismo, entonces:

10² = 10*10 = 100

6³ = 6*6*6 = 216

[12]² = 12*12 = 144

Reemplazando eso obtenemos:

100 + 216 - 144 = 316 - 144 = 172

Veamos tambien el siguiente problema:

-3² + (-2)⁴ + - 4³ + (-2)⁴

Apliquemos los exponentes, primero tenemos:

-3²

Notar que el exponente se le aplica solamente al 3, no al signo, entonces:

-3² = -(3)² = -3*3 = -9

En cambio, en:

(-2)⁴

El exponente si se le aplica al signo, entonces:

(-2)⁴ = (-2)*(-2)*(-2)*(-2) = 4*4 = 16

Los otros dos terminos dan:

- 4³ = -4*4*4 = -64

(-2)⁴ = 16

Reemplazando eso en la expresión:

-3² + (-2)⁴ + - 4³ + (-2)⁴ = -9 + 16 - 64 + 16 = -41

We get that the birds and the dancers will clock out again in 30 minutes.

We are given that:

a cuckoo clock has birds that pop out of their nests every 6 minutes.

And the dancers that pop out every 15 minutes.

Now, they have popped out the same time. For this to happen again, we will find the LCM of 6 and 15.

6 = 2 × 3

15 = 3 × 5

LCM = 2 × 3 × 5

LCM = 3 × 10

LCM = 30

So, they will pop out again after 30 minutes.

Therefore, we get that the birds and the dancers will clock out again in 30 minutes.

Answer:

[0, 8)

Step-by-step explanation:

To find the range, compute the values of the function at the edges of the interval.

The interval edges are -1 and 3

f(x = -1)  = (-1)² - 1 = 1 - 1 = 0.

f(x = 3) = 3² - 1 = 9 - 1 = 8   but does not include 3 so

so range of f(x) : 0  ≤ f(x) < 8

Note that we cannot have f(x) ≤ 8 only < 8 since the interval does not include x = 3

Range in interval notation is [0, 8)

The use of the square brackets on the left means the number is included in the interval; so 0 is included ( ≥ ).

The round brackets on the right mean that the number is not include (< 8 )

Answer:

  (a) $191,005.52

  (b) $180,309.67

  (c) lose $10,695.85

Step-by-step explanation:

You want the future values of an ordinary annuity of $12,000 over 12 years at interest rates of 5% and 4%. You also want the difference between the values.

The future value of an ordinary annuity with n annual deposits of P, at interest rate r compounded annually is given by ...

  FV = P((1+r)^n -1)/r

The value of $12,000 deposited for 12 years at 5% is ...

  FV = $12,000((1.05^12 -1)/0.05 = $191,005.52

At the end of 12 years, she will have $192,005.52 in her account.

The value of $12,000 deposited for 12 years at 4% is ...

  FV = $12,000((1.04^12 -1)/0.04 = $180,309.67

At the end of 12 years, she will have $180,309.67 in her account.

The amount at 5% is greater, so by investing in her sister's firm, the woman would lose ...

  $192,005.52 -180,309.67 = $10,695.85 . . . . amount lost

Step-by-step explanation:

Simplify the expression, and add/muiltiply where necessary.

Considering the volume of the hemisphere, it is found that she can make 48 cookies.

The volume of an hemisphere of radius r is given as follows:

[tex]V = \frac{2\pi r^3}{3}[/tex]

The radius is half the diameter, hence, for this problem:

r = 11.5/2 = 5.75.

Hence the volume of the bowl in cubic inches is given as follows:

V = 2π(5.75)³/3 = 398.16 cubic inches.

Consider the volume of a single cookie, the number of cookies that she can make is given by:

398.16/8.295 = 48 cookies.

$0.29 you save if you buy the big bag instead of 2 small bags .

The unitary method is a strategy that determines the value of many units based on the value of a single unit in addition to calculating the value of a single unit using the values of multiple units.

We must divide the value of one thing by the number of other items we wish to calculate the value of before multiplying that result by one.

From the question,

A huge bag of flour weighing 10 lbs costs $3.69 in total.

Currently, one 5-lb small bag costs $1.55.

Consequently, two 5-lb little bags cost $3.10 each.

Cost difference equals big bag cost minus two small bag expenses.

The price difference is equal to $3.69 minus $3.10.

$0.29 is the cost difference.

By purchasing two small bags of floor instead of one large bag, you will save $0.29.

Data interpretation refers to the process of using diverse analytical methods to review data and arrive at relevant conclusions. The interpretation of data helps researchers to categorize, manipulate, and summarize the information in order to answer critical questions.

The importance of data interpretation is evident and this is why it needs to be done properly. Data is very likely to arrive from multiple sources and has a tendency to enter the analysis process with haphazard ordering. Data analysis tends to be extremely subjective. That is to say, the nature and goal of interpretation will vary from business to business, likely correlating to the type of data being analyzed. While there are several different types of processes that are implemented based on individual data nature, the two broadest and most common categories are “quantitative analysis” and “qualitative analysis”

a. The value of r = 3, -1/2.

b. The 4th term of each progression;

As, per the given question;

Let the first three terms of GP be a, ar, and ar².

The 1st, 2nd and 3rd terms of a GP equals 1st, 9th and 21st terms of an AP respectively.

where, 'r' is the common ratio in GP and 'd' is the common difference in AP.

Part 1: Multiply equation 1 by 5 and 2 by 2 and subtract 1 from 2.

2ar² - 5ar - 3a = 0

Put a = 8 and solving.

16r² - 40r - 24 = 0.

Factorising the above equation;

(r - 3)(2r + 1) = 0

Thus, r  = 3 and r = -1/2

Part 2:

Case 1: For r = 3; a =8;

ar = a + 8d

d = 2.

Thus, 4th term = a + 3d

                        = 8 + 3×2

4th term = 14.

For GP;

4th term = ar³

              = 8(3)³

4th term = 216.

Case 2: For r = -1/2; a =8;

ar = a + 8d

d = -3/2

Thus, 4th term = a + 3d

                        = 8 + 3×(-3/2)

4th term = 7/2

For GP;

4th term = ar³

              = 8(-1/2)³

4th term = -1.

Therefore, the values for the r and 4th term is estimated.

Using their concepts, we have that the measures are given as follows:

a) Mean of 1.0126.

b) Average deviation of 0.01632.

c) Percent deviation of 1.6%.

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

For this problem, the 5 observations are given as follows:

1.040, 0.989, 1.009, 1.026, 0.999.

Hence the mean is given by:

M = (1.040 + 0.989 + 1.009 + 1.026 + 0.999)/5 = 1.0126.

The average deviation of a data-set is given by the sum of the absolute values of the difference between each value and the mean, divided by the number of observations.

Hence:

Ad = (|1.040-1.0126| + |0.989-1.0126| + |1.009-1.0126| + |1.026-1.0126| + |0.999-1.0126|)/5 = 0.01632.

The percent deviation of a data-set is given by the absolute deviation divided by the mean and multiplied by 100%.

Hence:

0.01632/1.0126 x 100% = 1.6%.

Answer:

  a. (-12, 14), (6, 2), (-3, 8)

  b. yes; R(-12, 14)

Step-by-step explanation:

Points P(-6, 10), Q(0, -6), and R lie on a line, with one of them being the midpoint of the other two. You want to know the possible locations of R, and its location if RQ=√208.

Point M is the midpoint of AB when ...

  M = (A +B)/2

If M and A are given, then B is ...

  2M -A = B . . . . . . above equation solved for B

There are three choices for the location of R.

P is the midpoint

  R = 2P -Q = 2(-6, 10) -(0, 6) = (-12, 20-6)

  R = (-12, 14)

Q is the midpoint

  R = 2Q -P = 2(0, 6) -(-6, 10) = (6, 12 -10)

  R = (6, 2)

R is the midpoint

  R = (P +Q)/2 = ((-6, 10) +(0, 6))/2 = (-6, 16)/2

  R = (-3, 8)

The possible coordinates of R are (-12, 14), (6, 2), (-3, 8).

The length of the given segment PQ is ...

  d = √((x2 -x1)² +(y2 -y1)²) . . . . . distance formula

  d = √((0 -(-6))² +(6 -10)²) = √(6² +(-4)²) = √(36 +16) = √52

This is half the length of RQ, so we must have P as the midpoint of RQ.

This distance information chooses one of the three points found in part (a), R(-12, 14).

Step-by-step explanation:

with ABCD and ABDE being parallelograms, this means a indicated by the marks

AB = ED = CD

and with BD = DF that means that the line segments BF and CE are intersecting each other at their midpoint.

so they represent a pair of diagonals of a parallelogram, which makes BCFE a parallelogram.
