Answer:

(X+1)²+4(y+3)² = (√-20)²

Step-by-step explanation:

The standard form of expressing equation ic;

(x-a)²+(y-b)² = r²

Given the expression

x²+4y²+2x+24y+21 = 0

Collect the like terms

x²+2x + 4y²+24y+21 = 0

Completing the squares

x²+2x +(2/2)² + 4(y²+6y)+21 = 0+(2/2)²

x²+2x +(2/2)² + 4(y²+6y+(6/2)²)+21 = 0+(2/2)²

x²+2x +1 + 4(y²+6y+(3)²)+21 = 0+1

x²+2x +1 + 4(y²+6y+9)+21 = 0+1

x²+2x +1 + 4y²+24y+36+21 = 0+1

x²+2x +1 + 4(y²+6y+9)+21 = 0+1

x²+2x +1 + 4(y+3)²+21 = 0+1

(X+1)²+4(y+3)² = 1 - 21

(X+1)²+4(y+3)² = -20

(X+1)²+4(y+3)² = (√-20)²

Step-by-step explanation:

Para calcular la relación entre los ingresos de Mary en 2019 (\(I_{2019}\)) con respecto a sus ingresos en 2018 (\(I_{2018}\)), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:

\(I_{2019} = 20\% \: I_{2018}\)      

\( I_{2019} = \frac{20}{100}I_{2018} \)      

\( \frac{100}{20}I_{2019} = I_{2018} \)        

\( 5I_{2019} = I_{2018} \)                  

Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

The first four non-zero terms are \(4, 4t, -32/3 t^3\), and 0 (the coefficient of \(t^4\)). So the answer is: \(4, 4t, -32/3 t^3, 0\)

The Taylor series for a function f(t) about t = 0 is given by:

\(f(t) = f(0) + f'(0)t + (f''(0)/2!) t^2 + (f'''(0)/3!) t^3 + ...\)

To find the first four non-zero terms of the Taylor series for f(t) = 4 +

sin(4t), we need to find its first four derivatives evaluated at t = 0.

f(0) = 4 + sin(40) = 4

f'(t) = 4cos(4t)

f'(0) = 4cos(40) = 4

f''(t) = -16sin(4t)

f''(0) = -16sin(40) = 0

f'''(t) = -64cos(4t)

f'''(0) = -64cos(40) = -64

f''''(t) = 256sin(4t)

f''''(0) = 256sin(4 × 0) = 0

Substituting these values into the formula for the Taylor series, we get:

\(f(t) = 4 + 4t - (64/3!) t^3 + ...\)

The crank angle value when the piston is at Top Dead Center (TDC) is 0 radians or 0 degrees. The maximum ratio of the crank radius to the connected length is 0.3.

The crank angle value refers to the angle between the crankshaft and a reference point when measuring the position of the piston. When the piston is at Top Dead Center (TDC), it is at its highest point in the cylinder. The crankshaft is positioned such that the connecting rod is aligned with the crank radius and the piston is at the topmost position. This corresponds to a crank angle value of 0 radians or 0 degrees.

Regarding the maximum ratio of the crank radius to the connected length, this value is given as 0.3. The crank radius is the distance from the center of the crankshaft to the center of the crank pin, and the connected length is the distance from the center of the crank pin to the center of the piston pin. The maximum ratio of 0.3 indicates that the crank radius is 0.3 times the connected length.

It's important to note that these values are specific to the context of the problem statement provided. Different engines or mechanisms may have different values for the crank angle at TDC and the maximum ratio of crank radius to connected length.

Answer:

Step-by-step explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

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

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x        2         4          6          

y        8         6          4                

5x + 3y = 42

3y = -5x + 42

y = \(-\frac{5}{3}x+14\)

x        0           3          6        

y       14           9          4                  

Point of intersection of these lines will be (6, 4).

Raj read a total of 9/12 of his book.

To find out how much of the book Raj read in total, we need to add the fractions representing the portions he read before dinner and after dinner. Raj read 7/12 of his book before dinner, and then an additional 2/12 of his book after dinner. Adding these fractions together gives us:

7/12 + 2/12 = 9/12.

Since the fractions have the same denominator (12), we can simply add the numerators to get the numerator of the total fraction. The denominator remains the same. So, Raj read a total of 9/12 of his book.

To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 3 in this case:

9/12 ÷ 3/3 = 3/4.

Therefore, Raj read 3/4 of his book in total.

One pathology associated with special cell types is multiple sclerosis (MS), a chronic neurological disorder affecting the central nervous system. MS involves damage to the protective covering of nerve fibers, known as myelin, which disrupts the communication between the brain and the rest of the body.

This can lead to a wide range of symptoms, including fatigue, muscle weakness, coordination problems, and cognitive impairment. I have had personal experience with a family member who was diagnosed with MS. Witnessing their journey with this disease has highlighted the challenges they face on a daily basis. The unpredictable nature of MS, with periods of relapse and remission, has made it difficult for them to plan their activities and maintain a consistent quality of life.

They have undergone various treatments, including medication and physical therapy, to manage symptoms and slow down the progression of the disease. Seeing their resilience and determination in adapting to the limitations imposed by MS has inspired me and reinforced the importance of ongoing research and support for individuals affected by this condition.

The trend projection for time period 18 is 197.6. The correct option is B

A mathematical equation used to represent the trend or pattern seen in a time series of data is called a linear trend expression, sometimes referred to as a linear trend model.

To find the trend projection for time period 18 using the given linear trend expression, we substitute t = 18 into the equation:

Yt = 129.2 + 3.8t

Y18 = 129.2 + 3.8 * 18

Y18 = 129.2 + 68.4

Y18 = 197.6

Therefore, the trend projection for time period 18 is 197.6.

The 95% confidence interval for the true average tip is approximately 12.25% to 13.95%.

The percentage (frequency) of acceptable confidence intervals that include the actual value of the unknown parameter is represented by the confidence level.

To construct a confidence interval for the true average tip, we can use the following formula:

Confidence Interval = (sample mean) ± (critical value) * (standard deviation / √n)

Given:

Sample mean (\(\bar X\)) = 13.1%

Standard deviation (σ) = 2.7%

Sample size (n) = 40

Confidence level = 95%

First, we need to find the critical value associated with a 95% confidence level. Since the sample size is relatively large (n > 30), we can use the Z-distribution.

The critical value for a 95% confidence level is approximately 1.96.

Now, let's calculate the confidence interval:

Confidence Interval = 13.1% ± 1.96 * (2.7% / √40)

Calculating the standard error (standard deviation / √n):

Standard Error = 2.7% / √40 ≈ 0.4277

Confidence Interval = 13.1% ± 1.96 * 0.4277

Calculating the endpoints of the confidence interval:

Lower Endpoint = 13.1% - 1.96 * 0.4277

Upper Endpoint = 13.1% + 1.96 * 0.4277

Rounding the endpoints to two decimal places:

Lower Endpoint ≈ 12.25%

Upper Endpoint ≈ 13.95%

Therefore, the 95% confidence interval for the true average tip is approximately 12.25% to 13.95%.

Answer:

I'm not quite sure how to point to which graph exactly, but I will tell you that it is the one that principal increases by one for six months, and interest decreases. It has "Month, Principal, Interest, and Total" written across the top in bold. Down the left-hand side, it has numbers 1-6. On the bottom, the first total is $363, and the second is $2076.

Step-by-step explanation:

There is very limited math involved in this question. The first step is to find a graph where each month, the principal number increases by one dollar and the interest decreases by one dollar. This should go on for six months. We can now eliminate two graphs. For a third, you must remember that the interest starts in the sixty, and the principal payment is in the two hundred eighties. By now, we have our graph. The final step to double-check this is to add up the total interest and principal (which should be on the side). All totals should be $346 as we're basically just trading one number for another (-1+1). You should also go to the bottom and fill in the blank in the principal column. In this box, you should put the total of all principals together.

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (24, - 4) ← 2 points on the line

m = \(\frac{-4-1}{24+1}\) = \(\frac{-5}{25}\) = - \(\frac{1}{5}\) , then

y = - \(\frac{1}{5}\) x + c ← is the partial equation

To find c substitute any of the 3 points into the partial equation

Using (4, 0 ) , then

0 = - \(\frac{4}{5}\) + c ⇒ c = 0 + \(\frac{4}{5}\) = \(\frac{4}{5}\)

y = - \(\frac{1}{5}\) x + \(\frac{4}{5}\) → D
