Write an equation in standard form for the line, where the points (-2, -1) and (0, 4) are on the line

Answers

Answer:

An equation in standard form for the line is:

[tex]\frac{5}{2}x-y=-4[/tex]

Step-by-step explanation:

Given the points

(-2, -1) and (0, 4)

The slope between two points

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:4\right)[/tex]

[tex]m=\frac{4-\left(-1\right)}{0-\left(-2\right)}[/tex]

[tex]m=\frac{5}{2}[/tex]

Writing the equation in point-slope form

As the point-slope form of the line equation is defined by

[tex]y-y_1=m\left(x-x_1\right)[/tex]

Putting the point (-2, -1) and the slope m=1 in the line equation

[tex]y-\left(-1\right)=\frac{5}{2}\left(x-\left(-2\right)\right)[/tex]

[tex]y+1=\frac{5}{2}\left(x+2\right)[/tex]

[tex]y=\frac{5}{2}x+4[/tex]

Writing the equation in the standard form form

As we know that the equation in the standard form is

[tex]Ax+By=C[/tex]

where x and y are variables and A, B and C are constants

so

[tex]y=\frac{5}{2}x+4[/tex]

[tex]\frac{5}{2}x-y=-4[/tex]

Therefore, an equation in standard form for the line is:

[tex]\frac{5}{2}x-y=-4[/tex]

A fox leaves its den and travels 725 yards northeast, then 950 yards west. How far, in yards is the fox from its den

Answers

Answer:

1,675

Step-by-step explanation:

add it

Using Pythagoras, the distance of the fox from its den would be 533.26 yards

Hypotenus = 900 yards

Adjacent = 725 yards

Distance from den = opposite

Opposite = √hypotenus² - adjacent²

Distance = √(900)² - (725)²

Distance = √810000 - 525625

Distance = √284375

Distance = 533.26 yards

Therefore, the fox is 533.26 yards from his den.

In late June 2012, Survey USA published results of a survey stating that 55% of the 579 randomly sampled Kansas residents planned to set off fireworks on July 4th. Determine the margin of error for the 55% point estimate using a 95% confidence level. The margin of error is: _____% (please round to the nearest percent)

Answers

Answer:

The Margin of Error E [tex]\simeq[/tex] 4.1 %

Step-by-step explanation:

Given that:

The sample size = 579

The sample proportion [tex]\hat p = 55\%[/tex] = 0.55

From the confidence interval of 95%

The level of significance ∝ = 1 - C.I = 1 - 0.95 = 0.05

The critical value of [tex]Z_{\alpha/2 } = Z_{0.025} = 1.96[/tex]

Thus;

The Margin of Error E = [tex]Z_{\alpha/2 } \times \sqrt{{\dfrac {\hat p ( 1 - \hat p }{n}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.55 ( 1 - 0.55) }{579}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.55 ( 0.45 )}{579}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.2475}{579}}[/tex]

The Margin of Error E = [tex]1.96 \times \sqrt{{4.2746114 \times 10^{-4}}[/tex]

The Margin of Error E = [tex]1.96 \times .020675[/tex]

The Margin of Error E = 0.040523

The Margin of Error E [tex]\simeq[/tex] 0.041

The Margin of Error E [tex]\simeq[/tex] 4.1%

A random survey of 30 students found that 17 played a musical instrument. If the school has 450 students, predict how many do not play an instrument.

Answers

Given:

A random survey of 30 students found that 17 played a musical instrument.

Total number of students = 450

To find:

Estimated number of students who do not play an instruments.

Solution:

A random survey of 30 students found that 17 played a musical instrument.

Let E be the event that student play an instrument.

So, probability that a student plays an instrument is

[tex]P(E)=\dfrac{17}{30}[/tex]

Probability that a student do not play an instrument is

[tex]P(E')=1-P(E)[/tex]

[tex]=1-\dfrac{17}{30}[/tex]

[tex]=\dfrac{13}{30}[/tex]

Now, number of students who do not play an instruments is

[tex]450\times P(E')=450\times \dfrac{13}{30}[/tex]

[tex]450\times P(E')=195[/tex]

Therefore, 195 students do not play an instrument.

A rectangle is constructed with its base on the​ x-axis and two of its vertices on the parabola yx. What are the dimensions of the rectangle with the maximum​ area? What is that​ area?

Answers

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, the complete question is:

A rectangle is constructed with its base on the x-axis and two of its vertices on the parabola y 81-x², what are the dimensions of the rectangle with the maximum area? what is the area?

Solution:

Given the parabola:

y = 81 - x²

Let the points (a,0) and (-a, 0) be points on the axis, this points touch the parabola at (a, 81 - a²) and (-a, 81 - a²).

Points (a,0), (-a, 0), (a, 81 - a²), (-a, 81 - a²) form the rectangle.

The length of rectangle = distance between (a,0) and (-a, 0) or between (a, 81 - a²) and (-a, 81 - a²) = 2a

The breadth of rectangle = distance between (a,0) and (a, 81 - a²) or between (-a, 0) and (-a, 81 - a²) = 81 - a²

Area of rectangle (A) = length × breadth = 2a × (81 - a²) = 162a - 2a³

A = 162a - 2a³

The maximum area is at dA / da = 0

dA / da = 162 - 8a² = 0

162 - 6a² = 0

6a² = 162

a² = 27

a = 5.2 units

Length = 2a = 2(5.2) =  10.4 units

Breadth = 81 - a² = 81 - 5.2² = 54 unit

Area = length × breadth = 54 × 10.4 = 561 unit²

A line passes through the point (-6,7) and has a slope of -4/3. Write an equation in slope-intercept form for this line.

Answers

Answer:

Step-by-step explanation:

y-7= -4/3 (x+6)

y-7= -4/3x-8

add 7 to both sides

y= -4/3x-1

The equation in slope-intercept form for the given line is 3y = -4x -3

What is Equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that a line passes through the point (-6,7) and has a slope of -4/3.

Standard equation of a line = y = mx + c where m is the slope,

Therefore, putting values of x and y to get the value of c

7 = -6*-4/3 + c

c = 7 - 8

c = -1

Equation = y = -4x/3 -1

Or, 3y = -4x -1

Hence, the equation of a line passing through the point (-6,7) and has a slope of -4/3 is 3y = -4x -1
