Answer:

By Pythagorean theorem: [tex]ET=\sqrt{113}[/tex]

By distance formula: [tex]ET=\sqrt{113}[/tex]

Step-by-step explanation:

The given rectangle has vertices R(-3,-4), E(-3, 4), C(4,4), and T(4-4).

The points have been plotted on the coordinate plane as shown in the attachment.

A. Using the Pythagoras Theorem;

[tex]ET^2=EC^2+CT^2[/tex]

We substitute the side lengths to obtain:

[tex]ET^2=EC+CT^2[/tex]

[tex]ET^2=49+64[/tex]

[tex]ET^2=113[/tex]

Take positive square root to obtain:

[tex]ET=\sqrt{113}[/tex]

B. The distance formula is given by:

[tex]d=\sqrt{(x_{2}-x_{1)^2+(y_{2}- y_{1} )[/tex]

The endpoints of ET are at E(-3,4) and T(4,-4).

Using the distance formula;

[tex]ET=\sqrt{4--3)^2+(-4-4)^2}[/tex]

[tex]ET=\sqrt{(7)^2} +(-8)^2[/tex]

[tex]ET=\sqrt{49+64}[/tex]

[tex]ET=\sqrt{113}[/tex]

The monthly payment will be 1,228.18.

What is principle amount?

The amount you owe at any one moment is the primary amount. When you first took out the loan, it is exactly your loan amount. The principle amount drops as you make EMI payments, and when it hits zero, your loan is closed.

The total price of the home is $241,000.

The down payment will be 15% among the total price.

Rest amount will be paid by taking loan for 30 years.

The down payment amount is

15% of $241,000 = $ 241,000×15/100 = $36,150.

Hence the loan amount is going to be the rest amount, that is,

$(241,000-36,150) =$204,850.

So the principle amount, P= $204,850.

Interest rate= 5% implies

interest, R= 5/100 = 1/20 = 1/12×1/20 (monthly) = 1/240.

Number of years, N= 30 years = 30×12 months = 360 months.

Hence the monthly payment will be

[  P × R × (1+R)N ] / [ (1+R)N - 1 ] = $1,099.68.

So the principle amount, P= $204,850.

Interest rate= 6% implies

interest, R= 6/100 = 1/12×6/100 (monthly) = 1/200.

Number of years, N= 30 years = 30×12 months = 360 months.

Hence the monthly payment will be

[  P × R × (1+R)N ] / [ (1+R)N - 1 ] = 1,228.18

Answer:

m = -4

b =1

y = -4x+1

Step-by-step explanation:

We want to find the slope and y intercept

Given the two points ( -1,5) and ( 1,-3), we can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( -3 -5)/( 1 - -1)

   = -8/( 1+1)

   = -8/2

   = -4

The y intercept is where it crosses the y axis

It crosses at 1

The slope intercept form of the line is

y = mx+b

y = -4x+1

Step-by-step explanation:

we need to find the value of x for which C(x) = 2200.

2200 = 270ln(x + 1) + 1900

300 = 270ln(x + 1)

300/270 = ln(x + 1)

10/9 = ln(x + 1)

e^(10/9) = x + 1

x = e^(10/9) - 1 = 2.037731778... ≈ 2.0 acres

for an average intake of 2200 calories per day the number of acres of land owned is approximately 2.0.

12/√3 is  the direction of the vector v .

What does a basic math vector mean?

A thing with both magnitude and direction is called a vector.

                               A vector can be visualized geometrically as a directed line segment, where the direction is indicated by an arrow and the length of the segment equals the magnitude of the vector.

Normalize (make length 1) the vector v = <1, 1, -1>.

||v|| = √(1^2 + 1^2 + (-1)^2) = √3.  

So, the unit vector u is given by u = v/||v|| = <1, 1, -1>/√3.  

To find the rate of change of the potential in the direction of the vector v, you should calculate the   ∇f(6, 6, 5) and multiply by u.

=<df/dx, df/dy, df/dz>*u

= <4x-3y+yz, -3x+xz, xy> {at (6, 6, 5)} * u

Answer:

let width=x

length = x + 2ft

Area = 82ft^2

Area= length×width

=(x+2)x

=x^2 +2x=82

x^2+2x-82=0

Use Quadratic Equation to get x.

x = -10.1(reject, length cannot be minus value or 8.11)

x = 8.11

width = 8.11ft

length = 10.11ft

The total distance ran during these days, written as a mixed number, is (38 + 3/4)mi

We know that the student ran a distance of (3 + 1/2) miles each day for 5 days, so the amount that the student ran in these 5 days is given by the product:

5*(3 + 1/2) mi = (15 + 5/2) mi

Now, on the next 5 days, the student ran a distance of (4 + 1/4) miles, so the total distance that the student ran in these days is:

5*(4 + 1/4) mi = (20 + 5/4)mi

Now to get the total distance that the student ran on the 10 days we need to add the two distances above, we will get:

(15 + 5/2) mi +  (20 + 5/4)mi

So we have a sum of mixed numbers, we can rewrite this as:

(15 + 5/2) mi +  (20 + 5/4)mi = (15 + 20)mi + (5/2 + 5/4)mi

(15 + 20)mi + (5/2 + 5/4)mi = 35mi + (10/4 + 5/4) mi

35mi + (10/4 + 5/4) mi = 35mi + 15/4mi

35mi + 15/4mi = 35mi + 12/4 mi + 3/4 mi

35mi + 12/4 mi + 3/4 mi  = (38 + 3/4)mi

That is the total distance that the student ran on the 10 days.

Answer:

97.5/100

Step-by-step explanation:

To write 97.5% as a fraction in simplest form, we first convert the percentage to a decimal by dividing it by 100: 97.5% / 100 = 0.975. We can then express this decimal as a fraction by using the fact that any number can be represented as a fraction with the number as the numerator and a power of 10 as the denominator: 0.975 = 0.975/1. Finally, we simplify the fraction by dividing the numerator and denominator by the greatest common factor, which in this case is 1: 0.975/1 = 97.5/100. Therefore, 97.5% can be written as the fraction 97.5/100 in simplest form.

Answer:

39/40

Step-by-step explanation:

97.5/100

   Step 1: Write down the percent divided by 100;

   Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 until you get an integer at the numerator.

   Step 3: Simplify (or reduce) the fraction if it is not in the simplest form.

1.  m∠5 + m∠6 = 180° - Pair of linear angles

2. ∠ 2+ ∠ 3 = ∠ 6 - Exterior Angle Theorem.

3. m∠2 + m∠3 + m∠5 = 180° - Sum of angles of Triangle

The angles that are created outside of a triangle are its external angles. In other terms, the angle created between one of a triangle's sides and its neighboring extended side is the triangle's exterior angle.

Each exterior angle of the triangle and its corresponding interior angle will form a pair of linear angles i.e the Sum of an Exterior angle and its corresponding interior angle is 180°.

A triangle's exterior angle is equal to the sum of its two opposite interior angles. This property of the triangle is known as Exterior Angle Theorem.

Here we have

∠2, ∠3, and ∠5 are the interior angles of a triangle

∠1, ∠4, and ∠6 are exterior angles of the same triangle

Let's assume that the given triangle is ΔABC

Can be represented as given in the picture  

As we know the sum of angles in a triangle = 180°

=> m∠2 + m∠3 + m∠5 = 180°  will be true

If we observe the given picture,

From line BC, m∠5 + m∠6 = 180°   [ Pair of linear angles ]

From Exterior angle Property

=> ∠ 2+ ∠ 3 = ∠ 6.

Therefore,

The correct statements are

1.  m∠5 + m∠6 = 180° - Pair of linear angles

2. ∠ 2+ ∠ 3 = ∠ 6 - Exterior Angle Theorem.

3. m∠2 + m∠3 + m∠5 = 180° - Sum of angles of Triangle.

2.51 x 10^5

Step-by-step explanation:

Scientific notation gives you a number between 1 and 10 multiplied by a power of ten. In this case, you'll want to use the significant digits, 251, and divide or multiply by a power of ten to get a number between 1 and 10.

251,000 can become 2.51 (which is between 1 and 10) multiplied by 10 to a certain exponent. All you need to do is calculate the exponent.

2.51 x 10^(?) = 251,000

For each power of 10, the decimal moves a space. Since you want the decimal to move 5 spaces, you'll want to multiply 2.51 by 10^5.

2.51 x 10 = 25.1

2.51 x 10^2 = 251

2.51 x 10^3 = 2510

2.51 x 10^4 = 25,100

2.51 x 10^5 = 251,000
