y = -1/5x +1/2 linear function has the same slope .

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all. Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula. We shall comprehend the slope-finding method and its applications in this essay.

First solve for the slope

m =[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

m=[tex]\frac{0-\frac{3}{5} }{\frac{1}{2} -\frac{1}{5} }[/tex]

m = [tex]\frac{-1}{5}[/tex]

Look for the linear equation with the same value of m after determining the slope (parallel equation).

Given that P is a point on the perpendicular bisector, l, of MN, we have proved that PM = PN because By the definition of reflection, point P is the image of itself and point N is the image of N.

We are given :

P is a point on the perpendicular bisector, l, of MN.

Now, we want to prove that PM = PN

A Reflection is a transformation in which the figure is the mirror image of the other. Every point is a mirror reflection of itself .

By the definition of reflection, we can deduce that point P is the image of itself , and point N is the image of M .

The line l acts as a Line of symmetry or axis of reflection.

Now, in transformations, we know that reflections preserve length and as a result, PM = PN.

Therefore, we will conclude that point N is the image of M .

The mean = 0.2,  variance = 0.03226 and Standard deviation = 0.1796

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

level            x

1             0.419

2            0.276

3            0.225

4            0.068

5            0.012

So, mean = (0.419+ 0.276 + 0.225+ 0.068 + 0.012)/5

mean = 0.2

level          x        (x- mean)       (x- mean)²        

1             0.419        0.219            0.0479  

2            0.276       0.076            0.0057

5            0.012        -0.188          0.0353

Answer:

the ratio is 6.5 : 1.5

Step-by-step explanation:

it asks "what is the ratio of time spent studying in math to studying for English?"

ratio uses the ":" mark. also you put the parts like this:

first part : second part

the parts can be found by looking for the "to" as indicated bold in the question

the first part of the ratio it asks is the "time spent studying in math" in hours which is 6.5

the second part of the ratio it asks is the "time spent studying in English" in hours which is 1.5

so the answer is:

6.5 : 1.5

Answer:

Ratio of time spent studying in math to studying for English

[tex]\large \text{$=\dfrac{13}{3}$ }[/tex]

Step-by-step explanation:

What is a ratio?
We use ratios to compare two numeric quantities or quantities with the same units

Basically a ratio of one quantity x to another quantity y can be expressed in the following ways, all read as the ratio of x to y

x/ y

x to y

x : y

The most useful way of representing a ratio is by using the fractional form because it can be used in determining other quantities

In this problem you spend 6.5 hours/week  studying for math and 1.5 hours/week studying for English

Since both units are the same (hours/week) we can compute the ratio as

[tex]{\dfrac{\text{Number of hours studying math}}{\text{Number of hours studying English}}\\\\= \dfrac{6.5}{1.5}\\\\[/tex]

We can simply this fraction as follows

Multiply both numerator and denominator by 10

[tex]= \dfrac{65}{15}\\\\[/tex]

Divide both sides by 5

[tex]\dfrac{65 \div 5}{15 \div 5}\\\\= \boxed{\bold{\dfrac{13}{3}\\\\}}[/tex]

This is the same as 13:3 or 13 to 3

(Be careful what is the numerator and what is the denominator.
If the question had asked for the ratio of hours studying English to hours studying Math then the ratio would be 1.5/65 = 15/65 = 3/13)

The equation for the linear function f(x) is f(x) = 2 / 7 x - 10 / 7

The linear function is f(x)

f(-2) = - 2 and f(5) = 0

Therefore, let's find the equation for the linear function f(x):

A linear function is a function that represents a straight line on the coordinate plane.

Therefore, linear function is represented as follows:

y = mx + b

where

Hence,

-2 = m(-2) + b

0 = 5m + b

b = -5m

Therefore,

m(-2) + - 5m = -2

-2m - 5m = -2

-7m = -2

m = 2 / 7

Therefore,

b = - 5 (2 / 7)

b = - 10 / 7

Hence,

f(x) = 2 / 7 x - 10 / 7

Answer:

  $1258.09

Step-by-step explanation:

You want the monthly annuity payment that will let you withdraw $150,000 per year forever from an account earning 8% after 30 years.

In order to withdraw an amount "forever," the withdrawal amount must be equal to the interest earned by the account.

  I = Prt

  150,000 = P(0.08)(1)

  P = 150,000/0.08 = 1,875,000

The value of an ordinary annuity is given by the formula ...

  A = P(12/r)((1 +r/12)^(12t) -1) . . . . . where P is the monthly payment, and r is the annual interest rate earned over a period of t years.

Using the values we know, we can find P:

  1875000 = P(12/0.08)((1 +0.08/12)^(12·30) -1) = 1490.359449P

  P ≈ 1258.09

You would need to deposit $1258.09 each month.

The formulas used here assume that the deposits and withdrawals occur at the end of the month.

Dragon needs 2.16 seconds to eat 90 kilograms of human beings.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that,

If a dragon can eat an entire cow weighing 500 kilograms in 12 seconds,

500 kilograms = 12 seconds

By unitary method

1 kilogram = 12 / 500

1 kilogram = 0.024 second

For 90 kilograms

90 kilogram=90 × 0.024 second

90 kilogram = 2.16 second

Thus, a dragon needs 2.16 seconds to eat 90 kilograms of human beings.

The dimensions of the fenced-in area is

either length = 35 yards and width = 80 yards ,  

or length = 40 yards and width = 70 yards .

In the question ,

it is given that

the total length of the fence = 150 yards

let L be the length of the area to be fenced

let B be the width of the house

Given that one side of the area is fenced using the back side of the house

So, the perimeter of the area to be fenced is 2L+B

equating both the perimeter we get

2L+B=150

B=150-2L       ....(i)

Given the area fenced-in portion = 2800 yards

also the fenced-in portion area = L×B

hence

L*B=2800

Substituting the values of B from equation(i) , we get

L*(150-2L)=2800

150L - 2L² = 2800

2L² - 150L + 2800 = 0

simplifying further , we get

L² - 75L + 1400 = 0

L² -40L -35L +1400 = 0

L(L-40) -35(L-40) = 0

(L-35)(L-40) = 0

So , L = 35 yards or L = 40 yards

Using L = 35 yards , we get B = 150-2(35) = 80 yards

and using L =40 yards , we get B = 150-2(40) = 70 yards .

Therefore , The dimensions of the fenced-in area is

either length = 35 yards and width = 80 yards   ,

or length = 40 yards and width = 70 yards   .

Equation = 1/4 x + 25 = 70

Solution = $180

Explanation:

Let the original amount she had before she went shopping be x

If she spent one-fourth on sloth, then the amount spent on cloth will be;

1/4 x

If she receives another $25 a week later totalling her money $70, then the equation that represents the situation will be;

1/4 x + 25 = 70

Find the solution

1/4 x + 25 = 70

1/4 x = 70 - 25

1/4 x = 45

x = 45 * 4

x = 180

Hence the amount she had before going for shoppind was $180

Equation of a straight line is an equation of the form y = mx + c, where

The slope is the gradient which is the ratio of the difference in the y direction to the difference in x direction.

given that the equation of the line is x + 3y = 7

rewriting the equation gives

y = -x/3 + 7/3

hence the slope is -1/3, and this is equated with the formula for slope

[tex]\frac{y-y_{1} }{x-x_{1} }=-\frac{1}{3}[/tex]

substituting the values for points  (-2,5)  and cross multiplying gives

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

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

y - 5 = -x/3 - 2/3

y = -x/3 - 2/3 + 5

y = -x/3 + 13/3

Rewriting the equation of the line in standard form is done as follows

y = -x/3 + 13/3
