The coordinates of three of the vertices of a rectangle PQRS are P(-2, 2), Q(4, 2), and R(4, -3). A. Find the coordinates of poi

Musya8 [376]

Answer:

The coordinates are (x,y) (-2,-3)

Step-by-step explanation:

We need to take note of the following properties.

1. A rectangle has 4 sides.

2. Two opposite sides of a rectangle are equal.

Coordinates of the triangle on the graph: P(-2, 2), Q(4, 2), R(4, -3) and S(x,y)

The length of the triangle:

We can get this from the x -coordinates of P and Q

Length = |-2 - 4| = 6 <em>(We are only taking positive values for dimensions. You cannot have a negative length)</em>

Recall that the length of the two sides is equal. Therefore, we can relate the length of the second side to its coordinates using the coordinates of R and S

x = 4-6; x = - 2

The breadth of the triangle

We can get this from the y -coordinates of Q and R

Breadth = |-3 -2| = 5 <em>(We are only taking positive values for dimensions. You cannot have a negative breadth)</em>

Recall that the breadth of the two sides is equal. Therefore, we can relate the breadth of the second side to its coordinates using the coordinates of R and S

2 - y = 5; y = -3

Therefore the coordinates are (x,y) (-2,-3)

Not sure if this is one was supposed to be 83

hammer [34]

Answer:

<K is 97 degrees

Step-by-step explanation:

4x + 13 = 5x - 8

5x - 4x = x

13 = x - 8

13 + 8 = 21

x = 21

Plug x = 21 in for that.

4(21) + 13 = 97

Hope it helped!

Nuclear Power Plant Some nuclear power plants utilize "natural draft" cooling towers in the shape of a hyperboloid, a solid obta

luda_lava [24]

Answer:

592.4 feet

Step-by-step explanation:

The cross section of the tower can be modeled by a hyperbola with its vertex at (x, y) = (100, 360) and its center at (0, 360). The point (x, y) = (200, 0) helps define the equation of it.

Basic form:

((x -h)/a)^2 -((y -k)/b)^2 = 1

Filling in (h, k) = (0, 360) and a=100, we can find b using the given point:

(200/100)^2 -((0-360)/b)^2 = 1

(360/b)^2 = 3 . . . . . . . . . . . . . . . rearrange, simplify

b^ = 360^2/3 = 43200

So, the equation of the hyperbola is ...

x^2/10000 - (y-360)^2/43200 = 1

Then for x = 150 (the distance from center at the top, we can find y to be ...

(150/100)^2 - (y -360)^2/43200 = 1

1.25 = (y -360)^2/43200

y = 360 +√(1.25·43200) ≈ 592.379

The height of the tower is about 592.4 feet.

Jason wants to receive monthly payments of $3,250 for 15 years. How much does he have to invest now in an annuity that has an an

LuckyWell [14K]

The amount she should invest today in the annuity is $455,450.40.

<h3>How much should be invested today?</h3>

The first step is to determine the future value of the monthly annuity.

Future value = monthly payment x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate = 3.6/12 = 0.3%
n = number of periods : 15 x 12 = 180

Future value : 3250 x [(1.003^180) - 1] / 0.003 = 774,171.92

The second step is to determine the present value of this future annuity:

774, 171.92 / (1.036^15) = $455,450.40
