For a geometric progression,
u3 = 4.5 and u7 = 22.78125. Find the value of the common ratio and the first term.

Answers

Answer 1

Answer: Ratio: 2:3

2 ==> 1st term

Step-by-step explanation:

22.78125/4.5=5.0625

5.0625^(1/(7-3))=

5.0625^(1/4)=1.5 ==> Ratio: 1:1.5 ==> 2:3

4.5 / 1.5^(3-1)=

4.5 / 1.5^2=

4.5 / 2.25 = 2 ==> 1st term

Answer 2

The first term (a) in the geometric progression is approximately 2.

The common ratio (r) is 1.5.

Here, we have to find the common ratio (r) and the first term (a) in the geometric progression, we'll use the formula for the nth term of a geometric sequence:

[tex]u_n = a * r^{(n-1)[/tex]

where:

[tex]u_n[/tex] is the nth term,

a is the first term,

r is the common ratio,

n is the position of the term in the sequence.

Given u3 = 4.5 and u7 = 22.78125:

For n = 3:

[tex]u_3 = a * r^{(3-1)}\\4.5 = a * r^2[/tex]

For n = 7:

[tex]u_7 = a * r^{(7-1)}\\22.78125 = a * r^6[/tex]

Now, we have two equations:

[tex]a * r^2 = 4.5\\a * r^6 = 22.78125[/tex]

Divide equation 2 by equation 1:

[tex](a * r^6) / (a * r^2) = 22.78125 / 4.5[/tex]

Simplify:

[tex]r^4 = 5.0625[/tex]

Now, take the fourth root of both sides to find the value of r:

r = √(5.0625)

r ≈ ± 1.5

Since r is the common ratio, it cannot be negative in a geometric progression.

So, the common ratio (r) is 1.5.

Now, we can find the first term (a) using equation 1:

[tex]a * r^2 = 4.5[/tex]

Substitute the value of r (1.5):

[tex]a * (1.5)^2 = 4.5[/tex]

a * 2.25 = 4.5

Divide by 2.25:

a ≈ 4.5 / 2.25

a ≈ 2

Therefore, the first term (a) in the geometric progression is approximately 2.

The common ratio (r) is 1.5.

What is the equation of the line in slope-intercept form that is perpendicular to the line y = x – 2 and passes through the point (–12, 10)?

y = x – 6
y = x + 6
y = x + 26
y = x + 10

Answers

The equation of the line that is perpendicular to given line is y = -x -2

Equation of a line

From the question, we are to determine the equation of the line

From the given information,

We have that the two lines are perpendicular

If two lines are perpendicular, the product of their slopes is -1

That is,

m₁m₂ = -1

Where m₁ is the slope of the first equation

and m₂ is the slope of the second equation

In the given equation,

y = x - 2

Compare to the general form of the equation of a line

y = mx + b

Where m is the slope

and b is the y-intercept

Thus,

In the equation, y = x - 2

Slope = 1

Therefore,

The slope of the equation we are to determine is -1

Also, from the given information,

The line passes through the point (-12, 10)

Using the point-slope form of a line

y - y₁ = m(x - x₁)

x₁ = -12

y₁ = 10

Thus,

y - y₁ = m(x - x₁)

y - 10 = -1(x - -12)

y - 10 = -1(x + 12)

y - 10 = -x -12

y = -x -12 + 10

y = -x -2

Hence, the equation of the line that is perpendicular to given line is y = -x -2

Answers

The amount of $123 will be equal to 1380 yens.

What is currency exchange?

The rate at which one currency will be exchanged for another is known as the exchange rate in the world of finance. The most frequent types of currencies are national currencies.

Given that the exchange rate of the Japanese Yen on a certain day was Rs 10.25. On the same day, if $3 was exchanged for Rs 345.

The amount of $123 in the yens will be calculated by forming the equations below:-

1 yen = 10.25 rs

1 rs = ( 1 / 10.25 ) yens  ........................(1)

$3 = 345 rs

1 rs = $3 / 345             .........................(2)

From both the equations:-

( 1 / 10.25 ) yens  = $ ( 3 / 345 )

$ 1 = ( 345 / ( 10.25 x 3 ) yen

$ 123 = ( 345 x 123  / ( 10.25 x 3 ) yen

$ 123 = 1380 yen

Therefore, the amount of $123 will be equal to 1380 yens.

In logarithm , value of function is 1/4.

How should log be defined?

The power to which a number must be increased in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents). For instance, the logarithm of 100 in base ten is 2, since ten multiplied by two equals 100: log 100 = 2, since 102 = 100.The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e.

Log x + log 6= log(2x+1)

(B ∩ C) = 2.

15 are taking chemistry, hence:

C + (A ∩ C) + (B ∩ C) + (A ∩ B ∩ C) = 15.

C + 6 + 2 + 2 = 15.

C = 5.

20 are taking english, hence:

Answers

Answer:

English: 48 minutes

Math: 54 minutes

Biology: 18 minutes

Step-by-step explanation:

Set up each subject with the variable x as the biology homework.:

English: (x+30)

Math: (3x)

Biology: (x)

Now add them together and set it equal to 120 (2 hours into minutes):

x + 30 + 3x + x = 120

Move 120 over to the left and simplify:

5x - 90 = 0

Solve:

5(x - 18) = 0

x - 18 = 0

x = 18

So biology is 18 minutes, and then plug 18 in for all the other subjects:

English: 18+30=48 minutes

Math: 3*18=54 minutes

Biology: 18 minutes

Answers

According to the given statement;

object A is moving faster by 8.184-5= 3.184

3.184 mph faster.

What is speed?

The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed only has a direction and no magnitude, it is a scalar quantity.

The most crucial scientific concept is measurement. Base or physical fundamental units are used to measure a wide range of measurable quantities. One such measurable quantity is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session.

According to the given valus;

Speed of object A = 12 ft per sec

I foot per second = 0.682 mph

12 ft per sec = 0.682x 12

= 8.184 mph

object В speed = 5 mph

object A is moving faster than B.

object A is moving faster by 8.184-5= 3.184

3.184 mph faster.

Hence,object A is moving faster than B by  3.184 mph.

Mariah thinks that the following equation is always true (that it's an identity). Is it always true? Find evidence
for or against the following equivalency rule by substituting various values in for a and b.
(a+b)² = a² + b²

Answers

Answer:  It is not always true, so it's not an identity

========================================================

Explanation:

Let's try replacing each 'a' with 1, and each b with 2. Feel free to pick two of your favorite nonzero numbers.

So we'll plug in a = 1 and b = 2

[tex](a+b)^2 = a^2+b^2\\\\(1+2)^2 = 1^2+2^2\\\\(3)^2 = 1^2+2^2\\\\9 = 1+4\\\\9 = 5\\\\[/tex]

The last equation is a false statement. This means the first equation is also false for a = 1 and b = 2.

This is one counter-example to disprove that (a+b)² = a² + b² is true in general.

Therefore, the equation is not an identity.

--------------

What is an identity however is this

(a+b)² = a² + 2ab + b²

If you were to plug in a = 1 and b = 2, then you'd get 9 on each side. This is one example to help partially confirm it's an identity.

More rigorous proof is in the form of using the FOIL method, the distributive property, or the box method.

Which of the following statements is false?

a) p → q
b) p ∨ q
c) q → p

Answers

The correct answers would be options (A) and (C).

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have been given two cases,

p: -3x + 8x - 5x = x

q: (3x)(5y) = 15xy

We have to need to isolate the variables:

p: -3x + 8x - 5x = x

⇒  (-3x - 5x) + 8x = x

⇒  -8x + 8x = x

⇒ x = 0

This is not always true, hence the statement is incorrect because this will hold true for only one value of x.

q: (3x)(5y) = 15xy

⇒ (3x)(5y) = 15xy

⇒ (3×5)(x×y) = 15xy

⇒ 15xy = 15xy

If both x and y are true for any value, then the statement is true.

Hence, p → q and q → p are false.

Therefore, the correct answers would be options (A) and (C).

Answers

The solution of the given linear equation in one variable 12 -3(2w + 1) = 7w -3(7 + w) is at w = 3.

According to the given question.

We have a linear equation in one variable.

12 -3(2w + 1) = 7w -3(7 + w)

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable 12 -3(2w + 1) = 7w -3(7 + w) is given by

12 - 3(2w + 1) = 7w - 3(7 + w)

⇒ 12 - 6w -3 = 7w - 21 -3w                 (by distributive rule)

⇒ 9 - 6w = 4w - 21                          (subtracting the like terms)

⇒ 9 + 21 = 4w + 6w

⇒ 30 = 10w

⇒ 30/10 = w

⇒ w = 3

Hence, the solution of the given linear equation in one variable 12 -3(2w + 1) = 7w -3(7 + w) is at w = 3.

4) It does not have transformation.

Geometric Transformation:

Images of triangles, quadrilaterals, pentagons, and other geometric shapes can undergo geometric transformations through the vertices in a Cartesian plane. Reflection, rotation, and translation are the three transformations; they only affect the geometric figure's location and not its size. Expansion and contraction are the two transformations that alter the geometric figure's size.

It is necessary to know the sort of transformation that took place given the points and their transformations.

1) We observe that point transformation A,B and C are transformed.

The transformation has the following form:

[tex](x,y)\rightarrow(x,-y)[/tex]

Every x-value remains constant, while every y-value flips from what it was.[tex](x,y)\rightarrow(x,-y)[/tex]

2)We observe that point transformations D, E, and F are contractions. Let's now identify the scalar that was applied to the transformation. We compute the product of the original point's coordinate and one of the transformation point's coordinates.

[tex]\frac{D^{'} _{y} }{D_{ y}} =\frac{4}{10} =\frac{2}{5}[/tex]

We multiply the coordinates of points E and F and check the results to make sure this is true.

For E:

[tex]\frac{2}{5} (5,10)=(2,4)\\Therefore,E^{'} =(2,4)[/tex]

For F:

[tex]\frac{2}{5} (10,-6)=(4,-2)\\Therefore,F^{'} =(4,-2)[/tex]

Therefore, The transformation has the following form:

[tex](x,y)\rightarrow\frac{2}{5}(x,y)[/tex]

3)We observe that point transformation G,H and I are transformed.

The transformation has the following form:

[tex](x,y)\rightarrow(-y,x)[/tex]

Every y-value flips from what it was to the opposite. The x and y values are reversed.[tex](x,y)\rightarrow(-y,x)[/tex]

4)We observe that point transformation J,K and L are not transformed.

The arithmetic mean of the monthly salaries of two employees is $ 3210 . One employee earns $ 3470 per month. What is the monthly salary of the other employee?

a. What is the given information and what is the unknown?

Answers

$2950 is the monthly salary of the other employee.

a. the given information = mean of two salaries =  3210

                                        = salary of 1st employee =3470

the unknown information = salary of 2nd employee = 2950

How to solve an equation?

To solve linear equations, utilize the steps that are provided below.

Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

We know that mean, [tex]m = \frac{\text{sum of the terms}}{\text{number of terms}}[/tex]

Here is given the

mean = 3210

term₁ = 3470                 (salary of one of the employees)

term₂ = ?                          (salary of the 2nd employee)

So, if we simplify

⇒ [tex]m = \frac{\text{sum of the terms}}{\text{number of terms}}[/tex]

⇒ [tex]3210 = \frac{3470 + term_2}{2}[/tex]

⇒ [tex]3210[/tex] × [tex]2 = 3470 + term_2[/tex]

⇒ [tex]6420[/tex] = [tex]3470 + term_2[/tex]

⇒ [tex]term_2 = 6420 - 3470[/tex]

⇒ [tex]term_2 = 2950[/tex]

So, the salary of the other employs is $ 2950

In the figure below angle ADB = (7x +2) degrees, and angle CDB = (3x - 2) degrees. Find the measure of the angle CDB.

Answers

Given that ∠ADB and ∠CDB are complimentary angles, the numerical measure of angle CDB is 25 degrees.

What is the numerical measure of angle CDB?

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

Given that;

∠ADB = (7x +2)∠ CDB = (3x - 2)m∠ CDB = ?

Since ∠CDA is a right triangle, the sum of ∠ADB and ∠CDB sums up to 90 degrees.

∠ADB + ∠CDB = 90°

(7x +2) + (3x - 2) = 90

Solve for x

7x +2 + 3x - 2 = 90

7x + 3x - 2 +2 = 90

10x = 90

x = 90/10

x = 9

Now, the numerical measure of angle CDB will be;

m∠CDB = (3x - 2)

Plug in x=9

m∠CDB = 3(9) - 2

m∠CDB = 27 - 2

m∠CDB = 25 degrees

Given that ∠ADB and ∠CDB are complimentary angles, the numerical measure of angle CDB is 25 degrees.
