What is the equation of the parabola with focus (1, 6) and directrix y = 1?

What Is The Equation Of The Parabola With Focus (1, 6) And Directrix Y = 1?

Answers

Answer 1

An equation of the parabola with focus (1, 6) and directrix y = 1 is: C. y = 1/10(x²) - 1/5(x) + 18/5

How to determine the equation of a parabola?

Mathematically, the standard equation of the directrix lines for any parabola is given by:

y = a(x - h)² + 2.

Where:

h and k are the vertex.a is a point.

Since the directrix is horizontal, the axis of symmetry would be vertical. Therefore, the equation of this parabola would be modeled by this standard mathematical expression;

(x - h)² = 4p(y - k)

Where:

h = 1

In Mathematics, the focus for either a right or left parabola is modeled by this mathematical expression (h + p, k) while its directrix is modeled by this mathematical expression x = h - p;

k + p = 6

k - p = 1

Solving the set of linear equations simultaneously, we have:

2k = 7

k = 7/2

For the value of p, we have;

p = 6 - k

p = 6 - 7/2

p = 5/2

Substituting the given parameters into the formula, we have;

(x - 1)² = 4(5/2)(y - 7/2)

x² - 2x + 1 = 10(y - 7/2)

x² - 2x + 1 = 10y - 35

10y = x² - 2x + 1 + 35

10y = x² - 2x + 36

y = (x² - 2x + 36)/10

y = x²/10 - x/5 + 18/5

y = 1/10(x²) - 1/5(x) + 18/5

In 2017, a company's sales were about $9 million. Sales increased at an approximately constant rate and reached
about $14.5 million in 2020, Estimate the sales in 2026. Show your work.

Answers

Answer: To estimate the company's sales in 2026, we need to find the average increase in sales per year and then use that to predict the sales for 2026.

The total increase in sales from 2017 to 2020 was $14.5 million - $9 million = $<<14.5-9=5.5>>5.5 million.

The number of years from 2017 to 2020 is 2020 - 2017 = <<2020-2017=3>>3 years.

Therefore, the average increase in sales per year was $5.5 million / 3 years = $<<5.5/3=1.83>>1.83 million/year.

Since the average increase in sales per year was $1.83 million/year, we can estimate the sales in 2026 by adding that amount to the sales for each year from 2020 to 2026. For example, the estimated sales for 2021 would be $14.5 million + $1.83 million = $16.33 million. Similarly, the estimated sales for 2022 would be $16.33 million + $1.83 million = $18.16 million, and so on.

Using this method, we can estimate that the sales for 2026 will be $26.73 million.

D. $4,108.70

Answers

The amount of simple interest is (a) $341.60

How to determine the amount of simple interest?

From the question, we have the following parameters that can be used in our computation:

Principal, P = $800

Rate, r = 6.1 %

Time = 7 years

The simple interest on the investment is calculated as

I = PRT

Substitute the known values in the above equation, so, we have the following representation

I = 800 * 6.1% * 7

Express 6.1% as decimal

So, we have the following representation

I = 800 * 0.061 * 7

Evaluate the products

I = 341.6

Hence, the amount is (a) $341.6

The value of the equation log(3 47) is about 4.235.

Describe log.

The power to which a number must be increased in order to obtain another number is known as a logarithm. For instance, since ten raised to the power of two equals 100, the base ten logarithm of 100 is 2: log 100 = 2.

Given that the approximate values of log(3) and log(47) are 1.1 and 3.85, respectively,

we must determine the approximate value of log(347).

log(a × b) = log(a) × log(b)

we get ,

log(3 × 47) = log(3) × log(47)

substituting , the values of log(3) and log(47) ,

we get ,

log(3 × 47) = 1.1 × 3.85

≈ 4.235

From a normally distributed population, a simple random sample of size 30 is taken. The mean of the sample is 144 and the standard deviation of the sample is 12. Which interval is a 99% confidence interval for the population mean?.

Answers

On solving the provided question, we got that The 90% confidence interval for the population mean mu is (140.4, 147.6)

The meaning of the standard deviation

A measure of how far the data are from the mean is called standard deviation (or). Data that have a low standard deviation are more likely to be centered around the mean than those that have a high standard deviation.

xbar = 144 (sample mean)

s = 12 (sample standard deviation)

n = 30 (sample size)

z = 1.645 (critical value at 90% confidence; use a calculator or table to compute this value)

[tex]The lower limit of the confidence interval is L, which is found by\\\\L = xbar - z(s/sqrt(n))\\L = 144 - 1.645(12/sqrt(30))\\L = 140.395985571616\\L = 140.4\\[/tex]

Similarly the upper limit U is

U = xbar + z(s/sqrt(n))

U = 144 + 1.645(12/sqrt(30))

U = 147.604014428384

U = 147.6

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The equation of the lines will be,

y = mx + c

y = 3x + c

-1 = 4 x 3 + c

c = -13

y = 3x - 13

y = mx + c

y = -4x + c

0 = -4 x -8 + c

c = -24

y = -x -24

y = mx + c

y = 1/6x + c

-10 = -1 + c

c = -9

y = -1/6x - 9

Therefore, the equation of the lines is,y = 3x - 13 y = -4x - 24 and y = -1/6x - 9.

What is perimeter?

The perimeter is the space surrounding a shape's edge.

The sum of the lengths of all the sides in a rectangular shape is its perimeter. P = 2( L+B)

Given that a rectangle's width is 17 feet and its perimeter is 110 feet, the length will be P = 2 (L + B)

110 = 2 (L + 17)
