What is the area of the rhombus shown below?

Answer:

r=0.6

Step-by-step explanation:

Consider geometric sequence

[tex]b_1=6,\\ \\b_2=3.6,\\ \\b_3=2.16,\\ \\b_4=1.296,...[/tex]

In geometric sequence

[tex]b_i=b_{i-1}\cdot r,[/tex]

then

[tex]b_2=b_1\cdot r[/tex]

and

[tex]3.6=6r,\ r=\dfrac{3.6}{6}=0.6.[/tex]

Note that

[tex]2.16=3.6\cdot 0.6,\\ \\1.296=2.16\cdot 0.6.[/tex]

This means that ratio r=0.6.

The width of the rectangular strip of land is 2/3 miles whose the width of the rectangular strip of land is 2/3 miles.

To find the width of the rectangular strip of land, we can use the formula for the area of a rectangle, which is:

Area = Length × Width

Given that the length of the rectangular strip of land is 3/4 miles and the area is 1/2 square mile, we can plug these values into the formula and solve for the width (W):

Area = 1/2 square mile

Length = 3/4 miles

1/2 = (3/4) × Width

To solve for the width (W), divide both sides by 3/4:

Width = (1/2) ÷ (3/4)

When dividing by a fraction, you can multiply by its reciprocal:

Width = (1/2) × (4/3)

Now, multiply the numerators and denominators:

Width = 4/6

The fraction 4/6 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:

Width = 2/3

So, the width of the rectangular strip of land is 2/3 miles.

Answer:

28 degrees

Step-by-step explanation:

180 = 10x + 5 + 65 because they are supplementary. x = 11.

Angle 2 = 180 - (Angle 1 + (4x - 7))

Angle 2 = 180 - ((180 - 65) + 4x - 7)

Angle 2 = 180 - (115 + 4x - 7)

Angle 2 = 180 - 152

Angle 2 = 28 degrees

Step-by-step explanation:

To solve equations, we use inverse operations. Normally, we use PEMDAS to simplify an equation. To solve it, we use the inverse of each in this order SADMEP. Solving an inequality is the same except for step. When dividing by a negative, the sign of the inequality changes.

We have [tex]5x+7>2(x-1)\\5x+7>2x-2[/tex] in simplified form. We begin by subtracting or adding constants across the equal sign. Then doing the same with the variable terms. We finish by dividing by the coefficient of the variable term.

Answer:

-99

Step-by-step explanation:

Given :

Arithmetic sequence : 15 , 9 ,3 , -3 , ........

To Find : 20th term .

Solution :

Formula of nth term in Arithmetic mean : [tex]a_{n} = a+(n-1)*d[/tex]  ---(A)

where

a = first term of sequence

n = term position

d = common difference

[tex]a_{n}[/tex] = the term you want to find

Thus in the given sequence:

a = 15 ( first term )

n = 20 th term ( given )

d = 9-15 = 3-9 = -6(common difference)

Putting values in (A)

⇒[tex]a_{20} = 15+(20-1)*(-6)[/tex]

[tex]a_{20} = 15-114[/tex]

[tex]a_{20} = -99[/tex]

Hence the 20th term is -99 i.e. option 1

Ava must work 43.5 more hours in order to save the rest of the money

Money is any item that generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. In math, it can be defined as the medium of exchange such as notes, coins, and demand deposits, to pay for commodities and services.

If you're self-employed, it's unwise  to work more than 40 hours a week on a regular basis because, you'll get a burst of productivity, the extra hours have diminished returns over time and within any time period.

Ava is saving for A new computer that cost 1218 she has already saved half of the money

Answer:

The answer is BD is the bisector angle

Answer:

See attachment.

Step-by-step explanation:

The main part of the function is an absolute value function and so it forms a V with the center of the V at (0,0). The sides of the V go up and over 1 unit at a time. However, since 2 is added to the it outside of the absolute value, the center of the V moves from (0,0) to (0,2). The sides stay the same. The division by 2 changes the sides. The sides move from up and over 1 unit to up 1 unit and over two units. It spreads or widens the graph. Lastly, the interval selects a specific part of the graph only from 0 to 6 on the x-axis. This takes just one side of the V and looks like a line segment. See attachment.

Answer:

We are given a function,

[tex]y=\frac{|x|+2}{2}[/tex]    if 0 ≤ x < 6

We need to draw the graph of the function.

We know that Parent function of the given function is Modulus function | x |.

Consider given function,

[tex]y=\frac{|x|+2}{2}[/tex]

[tex]y=\frac{|x|}{2}+\frac{2}{2}[/tex]

[tex]y=\frac{|x|}{2}+1[/tex]

So, the given function is translated 1 unit upward and compressed by factor of 1/2.

So the obtained graph is attached.

Answer:

Center (1,3) and radius 6

Step-by-step explanation:

We must complete the square to find the center and radius of the circle.

First make sure the x and y squared terms have 1 as their coefficients. We also make sure x and y terms together.

[tex]x^2-2x+y^2-6y=26[/tex]

We now create space between the x and y terms with parenthesis.

[tex](x^2-2x)+(y^2-6y)=26[/tex]

We complete the square by taking the middle terms -2x and the -6y - divide each and square them.

[tex]\frac{-2}{2} =(-1)^{2} =1[/tex]

[tex]\frac{-6}{2} =(-3)^{2} =9[/tex]

We add the squares to both sides.

[tex](x^2-2x+1)+(y^2-6y+9)=26+1+9[/tex]

Simplify.

[tex](x^2-2x+1)+(y^2-6y+9)=36[/tex]

And write the quadratics in factored form.

[tex](x-1)^{2} +(y-3)^{2} =36[/tex]

The center is (h,k) or (1,3). The radius is the square root of 36 which is 6.

Answer: Census.

Step-by-step explanation:

Given statement:- A research study is done to find the average age of all U.S. factory workers. The researchers asked every factory worker in Ohio what their birth year is.

This research is an example of a census because research in which information is obtained through the responses that all available members of an entire population give to questions.

In other words "Census is an official survey of population in a certain area and records various details about the individuals".

The study querying every factory worker in Ohio for their birth year to determine the average age of all U.S. factory workers is a census, as it attempts to gather data from every member of the entire population of interest. (First option)

The research study done to find the average age of all U.S. factory workers where the researchers asked every factory worker in Ohio their birth year is an example of a census. A census involves gathering information about every individual in the entire population of interest.

In this case, the population of interest would be all factory workers, and by querying every one of them (assuming it was indeed every single factory worker in Ohio), it constitutes a census, not a survey, which typically involves a representative sample.

It is not a convenience sample since that would imply a non-random selection based on ease of access, and it's not a simple random sample because not all members of the larger population (nationwide factory workers) have an equal chance of being included.

Answer:

Step-by-step explanation:

If Binu is 15, in 5 years they will be 20. And if Banu is 20 years older, in 5 years they will be 40 (becuase 15 + 20 = 35 and then + the 5 years) Thats twice Binu's age. So Binu is 15 I would assume?

Assuming what is meant by "infinite solutions" are infinite number of solutions of a logarithmic equation.  

[tex]\frac{1}{2}\log x^2 - \log \sqrt{x} - \log \sqrt{x} = 0[/tex]

and

[tex]\frac{1}{2}x-2\ln e^x=-\frac{3}{2}x[/tex]

Logarithmic equations with infinite solutions have graphs that look like dying-out exponentials. They can have infinite solutions because there are infinitely many values of y that satisfy the equation.

Examples of Logarithmic Equations with Infinite Solutions:
1. Logarithms to the base 10 (common logarithms):

In the equations below, y is the exponent to which 10 must be raised to equal x, so y is the common logarithm (log) of x.
x = 10^y
x = 10^y+1

2. Logarithms to the base e (natural logarithms):

In the equations below, y is the power to which e must be raised to equal x, so y is the natural logarithm (ln) of x.
x = e^y
x = e^y+1

Both of these equations have graphs that look like dying-out exponentials. They have infinite solutions because there are infinitely many values of y that satisfy the equation. Whenever the base is positive and not equal to 1, logarithmic equations can have infinite solutions.

Step-by-step explanation:

One way is to simply count the number of yellow squares.

I count 52, so the area is 52 square units.

Another way is to find the area of the larger rectangle and subtract from it the area of the smaller rectangle.

The larger rectangle is 11 by 6. Area = 11 * 6 = 66.

The smaller rectangle is 7 by 2. Area 7 * 2 = 14.

Answer:

[tex]y=3x[/tex]

y=57, when x is 19.

Step-by-step explanation:

We are asked to write an equation of variation where y varies directly as x.

Since we know that a directly proportional equation is in form: [tex]y=kx[/tex], where k is the constant of proportionality.

Upon substituting x=5 and y= 15 in our equation of variation we will get,

[tex]15=k*5[/tex]

[tex]k=\frac{15}{5}[/tex]

[tex]k=3[/tex]

Upon substituting k=3 in the standard equation of variation we will get our desired equation of variation as: [tex]y=3x[/tex].

Now let us find y, when x is 19.

[tex]y=3*19[/tex]

[tex]y=57[/tex]

Therefore, y equals 57, when x is 19.

Answer:

The required domain is [tex]x\ne -1[/tex]

Step-by-step explanation:

The given function is

[tex]f(x)=\frac{1-x}{x}[/tex]

We need the inverse of this function.

We first of all have to let [tex]y=f(x)[/tex].

This implies that,

[tex]y=\frac{1-x}{x}[/tex]

Next, we interchange [tex]x[/tex] and [tex]y[/tex] to obtain,

[tex]x=\frac{1-y}{y}[/tex]

We make y the subject to get,

[tex]xy=1-y[/tex]

[tex]xy+y=1[/tex]

[tex](x+1)y=1[/tex]

[tex]y=\frac{1}{1+x}[/tex]

The inverse function is

[tex]f^{-1}(x)=\frac{1}{1+x}[/tex]

The domain of this function is

[tex]x+1\ne 0[/tex]

Answer: 118.40, 300, $18,000

Step-by-step explanation:

a) p(x) = [tex]-\frac{1}{5} (8) + 120[/tex]

   p(8) =  [tex]-\frac{8}{5} + 120[/tex]

Final answer:

The total cost can be expressed as 5t + 10p or (5t) + (5 × 2p), representing the combined cost of five movie tickets and twice the amount of popcorn boxes for each of the five family members.

Explanation:

The total amount Xander's family spent on movie tickets and popcorn can be expressed with two different algebraic expressions. The cost for one family member is the cost of one ticket plus the cost of two boxes of popcorn. Since there are five members in the family, we multiply the cost of one person by five.

The first expression is 5t + 10p, which represents the cost of five tickets (5t) and ten boxes of popcorn (2 boxes per person), therefore, 5 times 2 boxes of popcorn (10p).

An alternative expression is (5t) + (5 × 2p), which explicitly shows the cost of five tickets (5t) plus the cost of two boxes of popcorn for each of the five members (5 × 2p).

Step-by-step explanation:

For words per minute divide 228 by 4

words per minute = [tex]\frac{228}{4}[/tex] ( = 57 )

Final answer:

To find the number of words Carlos types per minute, set up an equation and solve for 'x'.

Explanation:

To find the number of words Carlos types per minute, we can set up an equation using the given information. Let's assume that the number of words Carlos types in 1 minute is 'x.' We know that Carlos can type 228 words in 4 minutes. So, the equation would be:

228 words in 4 minutes = x words in 1 minute

To solve this equation, we can cross-multiply and divide:

(228 words) x (1 minute) = (4 minutes) x (x words)

Simplifying further:

x = (228 words) / (4 minutes)

Therefore, the equation that represents the number of words Carlos types per minute is:

x = 228 / 4

Answer:

200 adults

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know children and adults attended. We will let c be the number of children and a be the number of adults. Since 200 people attended, then c+a=200.

We also know they made $800 and adult tickets cost $4 and child tickets cost $2. We can write 2c+4a=800.

We will solve by substituting one equation into the other. We start by solving the first equation for c. c+a=200 becomes c=200-a.

Now we substitute c=200-a into 2c+4a=800. Simplify and isolate the variable a.

This means that 200 adults attended and 0 children attended.

Please, see the attached file.

Thanks.

Answer:

Options B, C and E are even functions.

Step-by-step explanation:

If f(x) = f(-x) then function is called to be even.

A). f(x) = ∛8x

f(-x) = ∛8(-x) = (∛8)(∛(-x) = 2∛(-x)

Therefore f(x) ≠ f(-x)

So function is not an even function.

B). [tex]f(x)=log_{9}x^{6}[/tex]

[tex]f(-x)=log_{9}(-x)^{6}[/tex]

[tex]=log_{9}(x)^{6}[/tex]

f(x) = f(-x)

So this function is even.

C). [tex]f(x)=\frac{1}{x^{8}+7x^{7}}[/tex]

[tex]f(-x)=\frac{1}{(-x)^{8}+7(-x)^{6}}[/tex]

            = [tex]\frac{1}{x^{8}+7x^{6}}[/tex]

f(x) = f(-x)

Therefore given function is even.

D). f(x) = [tex]e^{x^{8}-x }[/tex]

[tex]f(-x)=e^{(-x)^{8}-(-x)}=e^{x^{8}+x}[/tex]

Therefore f(x) ≠ f(-x)

So the given function is not even.

E). f(x) = |8x| - 3

f(-x) = |8(-x)| - 3

      = |8x| - 3

f(x) = f(-x)

Therefore, function is even.

F). [tex]f(-x)= -9(-x)^{10}+5(-x)^{4}-12(-x)[/tex]

[tex]f(-x)= -9(x)^{10}+5(x)^{4}+12(x)[/tex]

f(x) ≠ f(-x)

Therefore the given function is not an even function.

Options B, C and E are even functions.

Final answer:

Using the exponential growth formula, the approximate population of Henderson City in the year 2000 is calculated to be around 3,769,706 if the annual growth rate remains constant at 1.8%.

Explanation:

To calculate the approximate population of Henderson City in the year 2000, we can use the formula for exponential growth. The formula is
[tex]A = P(1 + r)^t[/tex]

where A is the amount of the final population, P is the initial population, r is the growth rate expressed as a decimal, and t is the time in years. In this case:

So the equation becomes:

A =[tex]3,381,000(1 + 0.018)^6[/tex]

Calculating this gives us the approximate population, A:

A ≈[tex]3,381,000(1.018)^6[/tex]

A ≈ 3,381,000(1.1155)

A ≈ 3,769,706

Therefore, the approximate population of Henderson City in the year 2000 would be 3,769,706 residents if the growth rate remains constant at 1.8%.
