a square on a coordinate plane has vertices at (4,-5) and (4,2). what is the perimeter of the square?​

Answer:

n = 2

Step-by-step explanation:

Since ∆A is similar to ∆B, therefore, the ratio of their corresponding sides would be equal.

Thus:

\( \frac{10}{n + 2} = \frac{6}{3} \)

\( \frac{10}{n + 2} = 2 \)

Multiply both sides by (n + 2)

\( \frac{10}{n + 2}(n + 2) = 2(n + 2) \)

\( 10 = 2n + 4 \)

Subtract 4 from each side

\( 10 - 4 = 2n + 4 - 4 \)

\( 6 = 2n \)

Divide both sides by 2

\( \frac{6}{2} = \frac{2n}{2} \)

\( 3 = n \)

n = 2

AB is about 53.74 so the answer is (A)

\( \sin(c) = \frac{opposite}{hypotenuse} \)

\( \sin(61) = \frac{47}{x} \)

\( (x)\sin(61) = \frac{47}{x} (x)\)

\((x) \sin(61) = 47\)

\( \frac{(x) \sin(61) }{ \sin(61) } = \frac{47}{ \sin(61) } \)

\(x = \frac{47}{ \sin(61) } \)

\(x = 53.74\)

Answer:

$52

Step-by-step explanation:

0.2 x 65 = 13

65-13 = 52

Answer:

x + x - 45 = 90

2x - 45 = 90

2x = 135

x = 67.5, so x - 45 = 22.5

The other two angles measure 22.5° and 67.5°.

Answer:

a. 3 mintes = 180 seconds

Answer:

155ysec ; 23400z+ 8400 secs

Step-by-step explanation:

3y mins = 3* 60=180y sec

3y mins - 25y sec= 180y sec - 25y= 155y sec

155ysec

From B

50(3z-2)min = 50 * 60 (3z-2) sec

= 3000(3z-2)=9000z-6000

4 (z + 1) hours =4*3600(z+1) =14400z + 14400z

Adding both expression we have;

9000z+14400z-6000+14400=23400z+ 8400 secs

23400z+ 8400 secs

Answer:

200

Step-by-step explanation:

Ella's name appears on the table 2/10 times, so we can multiply the denominator to make it 1000.

10x100 = 1000

If we multiply the denominator by 100, we must do the same to the numerator,

2x100=200

In 1000 draws Ella's name can be expected to come about  200 times.

An experiment is a way of determining how things may work.

From small sample space of experiments or models, we can assume the result of a larger sample space or models.

From the given table we observe that Ella's name came 2 times out of 10 random draws.

∴ In (10×100) = 1000 draw Ella's name can be expected to come about

(2×100) = 200 times.

C. 16 days

Step-by-step explanation:

Let´s say each worker does 1 ¨work¨, for each day, in order to complete the job in 15 days. That´s a total of 150 work.

If only 6 workers worked for the first 5 days, then we only do 30 by Day 5.

2 more workers join, so they do 8 work each day, 24 work in 3 days, 54 work by Day 8.

4 more workers join to complete the job, so we now do 12 work each day.

150 - 54 = 96

96 work is left to do, which would be done in 8 days by 12 workers.

8 days + 8 days = 16 days

The answer of the given question based on the scatterplot for determining  when she will reach 10,000 songs the answer is Maria will reach 10,000 songs in approximately 13.33 months, or about 14 months.

Slope is  measure of  steepness or incline of  line. In geometry and mathematics, slope is defined as  ratio of the change in  y-coordinates to  change in  x-coordinates between two distinct points on  line. This is often represented by  letter "m".

To determine when Maria will reach 10,000 songs, we need to find the point on the line of best fit where the y-value is 10,000.

From the scatterplot, we can estimate that the line of best fit intersects the y-axis at approximately 2000. This means that the initial number of songs downloaded was 2000.

Next, we need to find the slope of the line of best fit. Let's choose the points (5, 6500) and (10, 9500).

The slope of the line passing through these two points is:

slope = (y2 - y1)/(x2 - x1) = (9500 - 6500)/(10 - 5) = 600 songs per month

This means that Maria is downloading 600 songs per month on average.

Finally, we can use the slope-intercept form of a line to find the x-value when the y-value is 10,000:

y = mx + b

10,000 = 600x + 2000

8000 = 600x

x = 13.33

Therefore, Maria will reach 10,000 songs in approximately 13.33 months, or about 14 months.

\(y = \frac{x^3 +5}{6}\\\)

\(\frac{x^2}{2}\\\) is just the the derivative of \(f(x)\) since it it is the slope of the line tangent to the curve at \(x\). To find how \(f(x)\) is defined, we'll just take the anti-derivative of \(\frac{x^2}{2}\\\).

Recall:

\(\int x^n \mathrm{d}x = \frac{x^{n +1}}{n +1} &, &n \neq -1\\\)

Solving for \(f(x)\):

\(f(x) = \int \frac{x^2}{2} \mathrm{d}x \\ f(x) = \frac12 \int x^2 \mathrm{d}x \\ f(x) = \frac12 \cdot \frac{x^3}{3} \\ f(x) = \frac{x^3}{6} +C\)

We still have to solve for \(C\). Note that the point \((1,1)\) has to be on our graph so \(f(1) = 1\) or \(\frac{(1)^3}{6} +C = 1\\\).

Solving for \(C\):

\(\frac{(1)^3}{6} +C = 1 \\ \frac{1}{6} +C = 1 \\ C = 1 -\frac{1}{6} \\ C = \frac{6}{6} -\frac{1}{6} \\ C = \frac{5}{6}\)

We can finally write \(f(x) = \frac{x^3}{6} +\frac{5}{6}\\\) or \(f(x) = \frac{x^3 +5}{6}\\\). Since \(y = f(x)\), we can write it as \(y = \frac{x^3 +5}{6}\\\) as well.

Answer:

To find g(26) when g(x) = 7x + 2, we simply need to substitute x = 26 into the expression for g(x):

g(26) = 7(26) + 2

g(26) = 184

Now, to find (g of f)(x), we need to substitute f(x) into the expression for g(x):

(g of f)(x) = g(f(x)) = 7(f(x)) + 2

Since f(x) = x - 2, we can substitute x - 2 for f(x) in the expression for g(x):

(g of f)(x) = g(x - 2) = 7(x - 2) + 2

Simplifying this expression, we get:

(g of f)(x) = 7x - 12

Now, to find (g of f)(26), we simply substitute x = 26 into the expression we just found:

(g of f)(26) = 7(26) - 12

(g of f)(26) = 182

A variable is a characteristic or attribute that can take on different values. It is an observable and measurable property of an object or phenomenon, which can be used to describe and analyze it.

Parameters are used in inferential statistics to make conclusions about a population based on a sample of data.

(a) If you decide to select based on proportion of 10% from each group, the number of patients selected from each group would be: Group A = (10/100) x 100 = 10 patients Group B = (10/100) x 30 = 3 patients Group C = (10/100) x 30 = 3 patients.

(b) The classified groups can be named as follows: Group A = 10 years of education or less Group B = More than 10 years but less than or equal to 20 years of education Group C = More than 20 years of education.

(c) The sampling method employed in the selection process was stratified sampling. Stratified sampling is a type of probability sampling technique where the population is divided into homogeneous subgroups or strata, and the researcher selects a simple random sample from each subgroup or stratum.

The researcher chooses a proportion of participants from each subgroup to represent the population as a whole, which allows for more precise estimates of the population parameters than simple random sampling.

The sample is selected randomly from the stratified sample, which ensures that the sample is representative of the population.

The width of the field is 230 feet and the length is 310 feet.

Let's denote the width of the field as "x" feet.

The length of the field is 80 feet longer than the width, so it can be represented as "x + 80" feet.

To find the total amount of fencing material needed, we sum up the lengths of all four sides of the rectangular field:

2(length) + 2(width) = perimeter

Substituting the given values:

2(x + 80) + 2(x) = 1080

2x + 160 + 2x = 1080

4x + 160 = 1080

4x = 920

x = 920/4

x = 230

Therefore, the width of the field is 230 feet.

Now we can find the length by adding 80 feet to the width:

Length = Width + 80 = 230 + 80 = 310 feet.

So, the width of the field is 230 feet and the length is 310 feet.

cos(2a + B) is approximately equal to -0.2948.

why it is?

To find cos(2a + B), we can use the double angle formula for cosine:

cos(2a + B) = cos(2a)cos(B) - sin(2a)sin(B)

We already know the values of a and B, so we can substitute them into the formula and simplify using the trigonometric identities:

a = sin²-1(4/5) = 53.13° (rounded to two decimal places)

B = tan²-1(12/5) = 67.38° (rounded to two decimal places)

cos(2a) = cos²2(a) - sin²2(a) = (cos(a))²2 - (1 - (cos(a))²2) = 2(cos(a))²2 - 1

cos(2a) = 2(sin²-1(4/5))²2 - 1 = 2(0.8)²2 - 1 = 0.32

sin(2a) = 2sin(a)cos(a)

sin(2a) = 2(sin(sin²-1(4/5)))cos(sin²-1(4/5)) = 2(4/5)(3/5) = 0.96

cos(B) = 1/sqrt(1 + tan²2(B)) = 1/sqrt(1 + (12/5)²2) = 5/13

sin(B) = tan(B)cos(B) = (12/5)(5/13) = 0.48

Substituting these values into the formula for cos(2a + B) gives:

cos(2a + B) = cos(2a)cos(B) - sin(2a)sin(B)

cos(2a + B) = (0.32)(5/13) - (0.96)(0.48)

cos(2a + B) = 0.166 - 0.4608

cos(2a + B) = -0.2948

Therefore, cos(2a + B) is approximately equal to -0.2948.
