» In a parallelogram, opposite sides are equal in length.

This can be represented (in the vector way) by

'QR = '-SP = 'PS and 'RS = 'QS (let “'” represent a vector)

'QR + 'SP= 0 and 'RS-'QS = 0

Note the signs. The signs are determined by the arrows in the diagram. [A reminder: If you walk from a point A to a point B, your displacement vector is 'AB. If you walk back, that is, from B to A; your displacement vector is 'BA which is also equal to '-AB.]

This means: to prove that PQRS is a parallelogram, we must prove that

'QR + 'SP= 0 and/or 'RS-'QS = 0.

In this solution, we will only work on the first equation.

Permit me to remove this ' sign.

QR = QC+CR ...1

QR= QB+BA+AD+DR...2

ADD 1 TO 2

2QR= QC+CR+QB+BA+AD+DR

[LOOK CLOSELY, QC+QB=0 ; CR+DR=0. This is because BQ+QC = BC

BUT, BQ=QC= (BC)/2

QC-BQ= 0

AND, -BQ= QB

QC+QB= 0 ;)]

2QR= BA+AD...3

★

SP = SA+AP...4

SP= SD+DC+CB+BP...5

ADD 4 TO 5

2SP = SA+AP+SD+DC+CB+BP

[AGAIN, SA+ SD = 0 ; AP+ BP = 0]

2SP= DC+CB...6

3+6

2QR+2SP= BA+AD+DC+CB

[ BA+AD+DC+CB, IN A SIMPLE WAY, MEANS:

you start from B, and move to A (BA); from A to D (AD); from D to C (DC); and from C to B (CB). Therefore, you have gone from B to B (from your starting point and back). Hence, your total DISPLACEMENT is zero (you haven't changed your position).

2(QR+SP) = 0

'QR+'SP= 0

PROVEN

You can work out the other equation, but it is evident that PQRS is a parallelogram.

The probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We have the probability P(R) of randomly removing a red bead is 20%.

Let's suppose the number of red beads is n(R)

[tex]\rm P(R) = 20\% \Rightarrow 0.20\\\\\rm \frac{n(R)}{15} = 0.20[/tex]

n(R) = 15×0.20

n(R) = 3

Number of yellow beads = 15 -3 = 12

The probability randomly removing a yellow bead:

[tex]=\rm \frac{12}{15}[/tex]

= 0.8 or 80%

Thus, the probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.

Step-by-step explanation:

A= P(1+ r)^t

A= Amount, P = Principal, r = Rate (decimal form), t= time

A = 47000(1+0.0825)^12

A = 47000(1.0825)^12

A = 47000(2.589016751)

A = 121683.7873

Notice how

2x-5 = 2x - 2*2.5 = 2(x-2.5)

This means we can replace x with x-2.5 in the second step, in the "wrong way" column.

So,

y = ln(2x)

y = ln( 2(x-2.5) )

y = ln( 2x - 2*2.5 )

y = ln( 2x - 5 )

In the second step, the x-2.5 tells the reader to shift the curve 2.5 units to the right. Therefore, the 1/2 = 0.5 would shift to 0.5+2.5 = 3 as indicated by the correct graph.

Answer:

Box 2 has 3 times the volume of Box 1....

Answer:

  245 ft

Step-by-step explanation:

The geometry of the problem can be modeled by a right triangle in which Meena's height is the side opposite the angle of depression, and the distance to the boat is the side adjacent to the angle of depression. The mnemonic SOH CAH TOA reminds us of the relation ...

  Tan = Oppsite/Adjacent

__

The more useful trig function for this problem is the inverse of the tangent function, the cotangent. Using that function, we have ...

  cot(angle) = (distance to boat)/(Meena's height)

Then the distance to the boat is ...

  distance to boat = (Meena's height)×cot(angle)

The change in distance from A to B is then ...

  A -B = (120 ft)(cot(18°) -cot(44°))

  = (120 ft)(3.0777 -1.0355) ≈ 245.06 ft

The distance from point A to point B is about 245 feet.

Answer:

∠s = 158

Step-by-step explanation:

Since lines a and b are parallel,

∠s and 158 are alternate exterior angles.

Alternate exterior angles are equal if two lines are parallel.

So,

∠s = 158

Answer: 22°.

Step-by-step explanation: We're given the angle 158°, which is all we need. Angle u and 158°, have to add up to 180°.  180° - 158° = 22°, which is the angle measure of u.  You're probably wondering how this will help us.  The answer to that is it gives us the measurement of angle t, which is 158°.  Now, we'll do the same thing we did with angle u, which was to make angle u add up with 158° to make 180°.  We'll apply this to angle t and angle s.  We already know that angle t is 158°, so angle s has to be 22° in order to add up to 180°.  Therefore, your answer is 22° for angle s.

I will assume that we are trying to find the slope between (2,-6) and (-9,-6)

The slope's equation ⇒  [tex]\frac{y2-y1}{x2-x1}[/tex]

Let's set the variables:

    (x1, y1) --> (2, -6)

    (x2, y2) --> (-9, -6)

Now let's plug them in:

 [tex]Slope = \frac{-6--6}{-9-2} =\frac{0}{-11} =0[/tex]

Thus the slope of the line is 0.

  9.  3x² +x -2y +5 = 0

  10.  4x² +x -y +4 = 0

  11.  9x² -6x -3y -12 = 0

Step-by-step explanation:

"General form" of a polynomial equation is ...

  f(x, y) = 0

where the terms are arranged in lexicographical order and decreasing degree. That is, for terms of the same degree, x-terms are listed before y-terms, and xy terms are listed before y-only terms.

The leading coefficient can be positive or negative, your choice. (Positive is generally preferred.) For linear equations, "standard form" has the coefficients mutually prime. Making that happen for a general form polynomial would be your choice.

__

The highest-degree term is 3x². If we keep the leading coefficient positive, we can get general form by subtracting the expression on the left side of the equal sign.

  3x² +x -2y +5 = 0

__

Subtracting the right side gives ...

  4x² +x -y +4 = 0

__

Subtracting the left side gives ...

  9x² -6x -3y -12 = 0

or

  3x² -2x -y -4 = 0 . . . . . . remove a common factor of 3
