If you drive 23 miles south, make a turn and drive 39 miles east, how far are you, in a straight line, from
your starting point? Round your answer to the nearest tenth of a mile.

Answers

Answer:

45.27 miles

Step-by-step explanation:

Pythagorean theorem

23^2 + 39^2 = d ^ 2

d = 45.27 miles

If  a person drives 23 miles south and make a turn to east and drive 39 miles then the distance between starting point and person is 45.27 miles.

What is pythagoras theorem?

Pythagoras theorem applies in a right angled triangle. It says that in a right angled triangle the square of hypotenuse is equal to sum of squares of perpendicular and base of that triangle.

How to find distance?

When person drives towards south and then east , it forms a right angled triangle. We have to find the distance of person from the starting point. If we see the figure then we will come to know that we are require to find hypotenuse of triangle.

H=[tex]\sqrt{P^{2} +B^{2} }[/tex]

Answers

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.

Step-by-step explanation:

Answer:

Proven.

Step-by-step explanation:

So, fasten your seatbelts, we're about to go on a long ride(◠‿・)—☆

» 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.

A boat is heading towards a lighthouse, where Meena is watching from a vertical
distance of 120 feet above the water. Meena measures an angle of depression to the
boat at point A to be 18º. At some later time, Meena takes another measurement and
finds the angle of depression to the boat (now at point B) to be 44º. Find the distance
from point A to point B. Round your answer to the nearest foot if necessary.

Answers

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.

Why is it wrong to draw y=ln(2x-5) this way?

Answers

well because he did not do it

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.
