Note that for WKST to be a parallelogram, y must be equal to 8 and m∠S must be equal to 126°. Thus the correct option is (Option C).

A parallelogram is a basic quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposing or facing sides are of equal length, and its opposite angles are of equal measure.

To justify the above answer, note that:

Since Opposite angles of a parallelogram are congruent, we have

∠W = ∠T

That is:

 3x -18 = 2x +6

Collecting like terms over the equation sign, we have:

3x - 2x = 6 + 18

x = 24

Substituting x into the equation for ∠W = ∠T, we have:

3x -18 = 2x +6

3(24)-18 = 2(24) +6 =54

72-18 = 48 +6 = 54

Thus, the above expression is True. That is:

3x -18 = 54°; and

2x +6 = 54°.

Since The adjacent angle, W is supplementary to either of these, it means that:
∠W = 180° -∠E

⇒ 15y +6 = 180 -54

⇒ 15y = 120

y = 8

Thus, it is correct to state that the value of y and m∠S required to classify WKST as a parallelogram are:

y-8; ∠126° (Option C)

In total, there are 5 non-congruent triangles with integer sides that have a perimeter of 12.

The number of such non-congruent triangles can be found by considering all possible combinations of sides that add up to 12.

We can start by finding all possible combinations of two sides, and then adding the third side to make the perimeter equal to 12.

For example, for the two sides with lengths 1 and 11, the third side must be equal to 0, which is not allowed in a triangle.

The combinations of two sides are:

(1, 11), (2, 10), (3, 9), (4, 8), (5, 7), (6, 6).

For the combination (1, 11), the third side cannot be greater than 10, so it is not a valid triangle.

For the combination (2, 10), the third side can have lengths 0, 1, or 2, but none of these values result in a valid triangle.

For the combination (3, 9), the third side can have length 0, 1, 2, or 3. The only value that results in a valid triangle is 3, so there is 1 such triangle.

For the combination (4, 8), the third side can have length 0, 1, 2, or 4. The only value that results in a valid triangle is 4, so there is 1 such triangle.

For the combination (5, 7), the third side can have length 0, 1, 2, 3, or 5. The only value that results in a valid triangle is 5, so there is 1 such triangle.

For the combination (6, 6), the third side can have length 0 or 6. The only value that results in a valid triangle is 6, so there is 1 such triangle.

The volume of the drinking glass in cubic centimeters is 442.4189 cm^3 .

The cylinder is a three-dimensional shape having a circular base.

A cylinder can be seen as a set of circular disks that are stacked on one another.

The volume of a three-dimensional shape is equal to the amount of space occupied by that shape.

Now, think of a scenario where we need to calculate the amount of sugar that can be accommodated in a cylindrical box.

For any cylinder with base radius ‘r’, and height ‘h’, the volume will be base times the height.

Therefore, the cylinder’s volume of base radius ‘r’, and height ‘h’ = (area of base) × height of the cylinder

Since the  base is the circle, it can be written as

Volume =  πr^2 × h

Therefore, the volume of a cylinder = πr^2h cubic units.

Answer:

Below

Step-by-step explanation:

Company 1 charges 9.25 for 2.5 pounds and 14.50 for 6 pounds

      so  (6-2.5) pounds costs (14.50 - 9.25)

                3.5 pounds cost an increase of 5.25  

                       5.25 dollars / 3.5 pounds = 1.50 per pound

Company 2 's rate is the slope of the line =   (7.25-6.50)/ 1 = .75 dollar per pound   ( found by looking at the cost of 1 pound and the cost of 2 pounds)

Fixed cost for company 2 is the value where x = 0......the y-axis intercept = $ 5.75

Answer:

Step-by-step explanation:

Company 1:  find constant rate =  Δy/Δx, from any two (x,y) pairs on the data table

Constant rate = (14.50 - 9.25) / (9.25 - 2.5) = 1.5

Company 2 constant rate = $1.50/lb

Find the fixed fee for Company 1 by finding the y-intercept.

y - y1 = m(x - x1)     Choose any (x,y) from the data table

y - 9.25 = 1.50(x - 2.5)     Now put the equation in slope-intercept form.

y = 1.50x - 3.75 + 9.25

y = 1.50x + 5.50

Company 1 fixed fee = $5.50

Company 2:  find the slope of the line to get the constant rate, pick any 2 points on the line.

m = Δy/Δx = (7.25 - 5.75) /(2 - 0) = 0.75

Company 2 constant rate = $0.75/lb

Find the fixed fee by finding the y-intercept on the graph (where the line intersects the y axis at x = 0)

Company 2 fixed fee = $5.75

The mistake which Dennis made include the following: B. he didn't exclude x = 3, which makes the denominator in the original expression equal to zero.

In Mathematics, a rational expression simply refers to a type of expression  which is expressed as a fraction. This ultimately implies that, a rational expression is composed of two (2) main parts and these include the following:

Generally speaking, the excluded values of any rational expression simply refers to the values for which the expression is undefined, which is typically obtained when the denominator is equal to zero (0).

Rational expression = (x² - 6x + 0)/(x² + x - 12)

When x = 3, we have the following expression:

Rational expression = (x² - 6x + 0)/(3² + 3 - 12)

Rational expression = (x² - 6x + 0)/(9 + 3 - 12)

Rational expression = (x² - 6x + 0)/0

Rational expression = undefined.

(a) The work done in pulling the rope to the top of the building is approximately 4800 ft-lb.

(b) The work done in pulling half the rope to the top of the building is approximately 2400 ft-lb.

The work done in pulling the rope to the top of the building can be calculated using a Riemann sum:

Where Δx is a small change in the length of the rope, g is the acceleration due to gravity (32 [tex]ft/s^2[/tex]), and the sum is taken over the entire length of the rope (from 0 to 100 ft).

Expressing the work as an integral, we have:

W=∫ [tex]0^{100} (0.8 lb/ft) x (g) x (x) dx[/tex]

Evaluating this integral gives us the work done in pulling the rope to the top of the building:

[tex]W = (0.8 lb/ft) x (g) x (x^2/2)[/tex] evaluated from x=0 to x=100

W = 4800 ft-lb

(b)To find the work done in pulling half the rope to the top of the building, we simply evaluate the integral from x=0 to x=50 (the length of half the rope).

Functional continuity and derivative continuity (slope smoothness) between the device saturated and device active segments is the value of V12, VOL and Vhr, Vih and Get the NM2 & NmH

What is Functions?

Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Suppose the threshold vintage of N- mas is VTO

(i) Vin < VTO – Cat of f

(ii) VTO < Vin < V out – Saturation

(iii) Vin > V out + VTO – Liniar

When N-Nos is in Liniar

IR = Kn/2 { 2.(Vin-VTO). V out – V2out }

Cat calculation of VOH,

V out = V Do – RL- IR

When Vin is Low, i.p. Vin <Vto, the M mess is Off Home ID = IR = O

Calculation of VOL,

Let us assume Vin = VoH

= VDo

Since Vin – VTO > V Out, the Transitar is in Lininers,

IR= VDo – V out

Off have IO = IR = o

Calculation of VOL,

Let us assume Vin = VOH = VDO

Since Vin – VTO > V out, the Transifar is in Linears,

IR= VDO – V Out / R2

Using KCL – IR = IO

VDO – VOL / R2 = Kn/2 { 2(VOD  - VTo ) . Vo2 – VOL2}

Vol2 – 2 .{ VOD – VTO + 1/KnR2 } VOL + 2/KnRL . VDD = 0

On Solving for VOL,

VOL = VDD = VTO + 1/KnRL - /- ( VDD – VTO + 1/KNR2 ) 2 – 2VDD/KnR2

D Vot/DVin = 1

For VOCD > Vin – VTO; The N-Mas in Saturation

VDD – V Out /R2 = Kn/2 ( Vin – VTO ) 2

-1/R2 . D V out / D Vin = Kn( Vin – Vto )     put Vin = Vin

-1/RL ( -1) = Kn( Vin – Vto )

Calculation of Visit :-

Put D V out / D Vin = -1

When V Out  < Vin – Vto: M- mas Linier

Vdd – V out / RL = Kn/2 { 2- ( Vin –Vto ) Vout – V2 out }

Differtatyboth side  by d Vin:

-1/RL – D Vout/D Vin = kn/2 { 2.( Vin – Vto) D v out /d Vin

= 2 vat . Dat/dxt

Vdd – V out /R2 = Kn/2 { 2. ( Vin – VTO) V out – V2 Out }

Diffent Both side by D Vin .

-1/RL. DV out/DVin = Kn/2 {2. (Vin – Vto) Dv out / D vin + 2 vat .dat/Dithal      ------- ( i)

Put  dV out/D vin = -1

                                         Put Vin = VTT

-1/RL (-1) = Kn{( Vin – Vto ) – (-1) +2 V out }

VTH = Vto +2 V out -1 / Kn RL ----------(II)

Now Put the Value of Vin From ( II ) in ( I) in the Place of Vin.

Then

Vin = Vto + 8/3 VDo/KnRL – 1/knRL

Now ,Nasie Margin :-

NM2 = V12 – Vol

NMH = Vas – Vin

Substitute the value of V12, VOL and Vhr, Vih and Get the NM2 & NmH.
