Solve the equation below.

never [62]

Answer:

( c ) x = 2.5

Step-by-step explanation:

$3(17x - 6.5) = 108$

divide both side of the equation by 3...

$17x - 6.5 = 36$

$17x = 36 + 6.5$

$17x = 42.5$

$x = 2.5$

hence the value of x is 2.5...

Which of the following points below represents (- 2, - (5pi)/4) the polar grid?

Maru [420]

Answer:

Well, when we have a point in rectangular coordinates (x, y) and we want to write it in polar coordinates (r, θ) the rule we use is:

r = √(x^2 + y^2)

θ = Atg(Iy/xI) + 90°*(n - 1)

where n is number of the quadrant where our point is.

For example, if we are on the second quadrant, we use n = 2.

Now, if instead, we have the point (r, θ) and we want to rewrite it in rectangular coordinates, then the transformation is:

x = r*cos(θ)

y = r*sin(θ)

Now we have the point (- 2, -(5pi)/4) because the first part is negative, this number can not be in polar coordinates (r can not be negative) then we have:

x = -2

y = -(5*pi)/4

Using the first relation, we can find that:

r = √( (-2)^2 + (-5*3.14/4)^2) = 4.4

(rememer that the point (- 2, -(5pi)/4) is on the third quadrant, then we will use n = 3.)

θ = Atg(-(5*pi)/4/-2) + 90°*(3 - 1)= Atg((5*pi)/2) + 180° = 82.7° + 180° = 262.7°

Then the point that represents (- 2, - (5pi)/4) in polar coordinates is the point:

(4.4, 262.7°)

If instead of degrees, the angle part is written in radians, we have:

180° = 3.14 radians.

262.7° = x radians.

then:

x/3.14 = (262.7)/180

x = 3.14*(262.7)/180 = 4.58 radians.

then the point will be:

(4.4, 4.58 radians)

Plz someone help!!!!! if i dont pass this my dad will kill me! I mean it y'all

Remark

You have to do a couple of preliminary calculations before you can find the areas.

For example, how wide is the hallway and how long is it?

Step One

Find the length and Width of the Hallway going left to right.

Length of the Hallway = Width of the House - The width of the bedroom.

Length of the Hallway = 40' - 15' = 25'

Width of the Hallway = Width of the bedroom - Width of the kitchen

Width of the Hallway = 15' - 10' = 5'

Step Two

Find the dimensions to the hallway going up and down.

The length is just read from the diagram. It is 12'.

The width = The Length of the left right hallway - width of the TV room - width of the balcony

The width = 25 - 13 - 5

Step Three

Find the long base of drawing room. It is the same as the left, right hallway = 25'

Step Four

Find the area of the rooms.

Kitchen = L * W = 25 * 10 = 250 sq. Feet

Bedroom = s*s = 15 * 15 = 225 sq. Feet

left Right hallway = L*W = 25 * (15 - 10) = 25 * 5 = 125 sq. feet

Up Down Hallway = L*W = 12 * 7 = 84 square feet.

Total Hallway = 209 square feet.

TV Room = L*W = 12 * 13 = 156 square feet.

Drawing Room

Trapezoid 1

b1 = 13 + 7 = 20 feet

b2 = 25 feet Same as the left/right hallway.

h = 5 feet

Area = (b1 + b2)*h/2

Area = (20 + 25)*5/2 = 112.5 sqr feet.

Balcony

Trapezoid 2

b1 = 12 feet

b2 = 12 + 8 = 20

h = 5 feet

Area = (b1 + b2)*h/2 = (12 + 20)*5/2 = 80 square feet.

Note

I have found all the areas. Now you can arrange them and put them in order.

To stay within your budget the area of the house an garage combined is at most 3000 square feet. The area of the garage is 527 s

hjlf

I'm not sure but the answer would be 2w+1236.5+527 ≤ 3000

The answer to that equation would be w ≤ 618.25
The length is 618.25
The width is 618.25
