The coordinates of the vertices E (-8,9), F(-4,9), G(-4,2), and D(2,-8) when rotated 90° counterclockwise around the origin of the new coordinates will be E'( - 9, - 8 ), F'( - 9, - 4 ), G'( - 2, - 4 ), and D'( 8, 2 ).

A point A( x, y ) becomes A' when a point is rotated 90 degrees counterclockwise about the origin ( - y, x ). To put it another way, flip x and y, and make y negative.

Therefore, when point E( - 8, 9 ) is rotated 90° counterclockwise around the origin will be:

E'( - 9, - 8 )

When point F( - 4, 9 ) is rotated 90° counterclockwise around the origin the new point will be:

F'( - 9, - 4 )

When point G( - 4, 2 ) is rotated 90° counterclockwise around the origin the new point will be:

By solving a system of equations we can see that there are 400 main-floor seats and 500 balcony seats.

Let's define the two variables:

We know that if all the seats are sold, then the total income is $5,200, we can write the equation:

x*$8 + y*$4 = $5,200

And if 25% of the main-floor and 50% of the balcony seats are sold, then we get an income of $1800, then we can write:

0.25*x*$8 + 0.5*y*$4 = $1,800

x*$2 + y*$2 = $1,800

So we have a system of equations:

x*$8 + y*$4 = $5,200

x*$2 + y*$2 = $1,800

If we subtract twice the second equation for the first one we get:

(x*$8 + y*$4) - (x*$2 + y*$2) = $5,200 - 2*$1,800

x*$4 = $1,600

x = $1,600/$4 = 400

So there are 400 seats on the main-floor.

Using the first equation we can find:

x*$8 + y*$4 = $5,200

400*$8 + y*$4 = $5,200

$3,200 + y*$4 = $5,200

y*$4 = $5,200 - $3,200 = $2,000

y = $2,000/$4  = 500

So there are 500 balcony seats.

Step-by-step explanation:

Using the median concept and the quartiles, we have that:

In this problem, there are 12 elements, hence:

Thus, Q1 = 120, Q3 = 160 and the IQR is:

IQR = 160 - 120 = 40.

1.5 IQR is: 1.5 x 40 = 60.

Partial Derivatives

d/dx(8 e^(4 x) sin(7 y))

Factor out constants:

= 8 (d/dx(e^(4 x))) sin(7 y)

Using the chain rule, d/dx(e^(4 x)) = (d e^u)/(du) (du)/(dx), where u = 4 x and d/(du) (e^u) = e^u:

Answer:

Step-by-step explanation:

You want the distances north and east of the origin that a plane ends up after flying 400 km at a bearing of 25°, then 700 km at 80°.

For some distance r and bearing angle θ, the (north, east) coordinates will be ...

  (north, east) = (r·cos(θ), r·sin(θ))

For the trip at hand, the final coordinates of the plane are ...

Distance north = (400 km)cos(25°) +(700 km)cos(80°)

  = 362.52 km +121.55 km = 484.07 km

B is about 484 km north of O.

Distance east = (400 km)sin(25°) +(700 km)sin(80°)

  = 169.05 km +689.37 km = 858.41 km

B is about 858 km east of O.

45 inches s the perimeter of a regular, triangular yield sign with aside length of 15 in

The perimeter of a shape is the sum of the lengths of all its edges. For example, a triangle has three edges, so its perimeter is equal to the sum of those three lengths.

The perimeter of a square can be easily calculated if one side and all other sides are given as being the same length; for example, a square with sides measuring 5 inches long has a perimeter of 20 inches because 5 x 4 = 20. By multiplying the sum of the length and width by two, one can determine a rectangle's perimeter.

We will use the simple perimeter formula as yield sign is equilateral triangle

So, 15 × 3 = 45 inches

The range of the salary will be the closed interval [23,200, 26,800].

The absolute function is also known as the mode function. The value of the absolute function is always positive.

The absolute function is given as

f(x) = | x |

A new hire at one organization may expect to get an average beginning pay of $25,000 per year. The absolute divergence from the real compensation is no more than $1800.

Let 'x' represent the actual salary. Then the inequality is given as,

|x - 25,000| ≤ 1800

Answer:

17

Step-by-step explanation:

Angle 2 and angle 4 are alternate exterior angles so they congruent angles which means they have same angle measurement.

To find the measure of angle 2 we first need to find the value of x.

And to do that we can write the following equation based on the information we have in hand:

6x + 8 = 4x + 11 transfer like terms to the same side of the equation

6x - 4x = 11 - 8 add/subtract like terms

2x = 3 divide both sides by 2

x = 1.5 now to find the measure of angle 2 replace x with 1.5

6×(1.5)+8 = 17

The slope of a line that passes through the ordered pairs (0,1) and (3,5) would be m = 4/3.

Slope tells how vertical a line is.

The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

WE have been given line that passes through the ordered pairs (0,1) and (3,5).

Slope = m

Therefore,

[tex]m = \dfrac{y-q}{x-p}\\\\m = \dfrac{5 -1}{3-0}\\\\m = \dfrac{4}{3}[/tex]

Hence, the slope of a line that passes through the ordered pairs (0,1) and (3,5) would be [tex]m = \dfrac{4}{3}[/tex].

The down payment is $112,000.

And, Amount of the mortgage loan is $168,000.

Here,

Alvira and Barry Gomez purchased a home priced at $280,000.

They put down 40%.

We have to find down payment.

And, Amount of the mortgage loan.

What is Down payment?

A sum of money that a buyer pays in the early stages of purchasing an expensive good or service is called down payment.

Now,

Alvira and Barry Gomez purchased a home priced at $280,000.

They put down 40%.

Hence, The down payment = $280,000 x 40%

                                          = $280,000 x 40 / 100

                                          = $112,000

And, Amount of the mortgage loan = Total amount - Down payment

                                                      = $280,000 - $112,000

                                                      = $168,000

Now the original salary will be,

→ x + (x × 2)/100 = 11874

→ x + 0.02x = 11874

→ 1.02x = 11874

→ x = 11874/1.02

Answer:

  g(x) = 3x +5

Step-by-step explanation:

You want the function that results from translating f(x) = 3x upward by 5 units.

The y-coordinate of a point tells how far above the x-axis it is. Adding 5 to the y-coordinate will move that point 5 units farther above the x-axis, which is to say 5 units upward.

The y-coordinate of a point on a graph is the value of the function of the x-coordinate of that point. That is, each point is (x, f(x)). If we want to translate that point 5 units upward, we add 5 to the function value:

  (x, f(x) +5) . . . . . graph translated 5 units up

Using the given definition of f(x), this becomes ...

  (x, 3x +5)

The translated function is defined as g(x), so we have ...

  (x, g(x)) = (x, 3x +5)

or ...

  g(x) = 3x +5

The fraction 24/56 can be simplified to 3/7, and we can't keep simplifying this.

Here we want to simplify the fraction 24/56. To do so, we need to find the greatest common factor between 24 and 56, to find that, we need to write both of these numbers as a product of their prime factors.

We will get:

24 = 2*2*2*3

56 = 2*2*2*7

We can identify the greatest common factor between parenthesis:

24 = (2*2*2)*3

56 = (2*2*2)*7

So the greatest common factor is 2*2*2 = 8, then we can divide both numerator and denominator by 8, we will get:

24/8 = 3

56/8 = 7

Then the fraction 24/56 can be simplified to 3/7, and we can't keep simplifying this.

Polynomial equation with integer coefficients that has roots x= -1 and

x = -6 is equal to x² +7x +6=0.

As given in the question,

Given roots for the polynomial equation with integer coefficient are

x = -1 ⇒ x + 1=0

x = -6 ⇒ x + 6 =0

Polynomial equation is

( x + 1) ( x + 6) =0

⇒ x² + 1x + 6x + 6 =0

⇒ x² + 7x + 6 =0
