How much greater is the distance between buoys A and B than the distance between

buoys B and C?​

How Much Greater Is The Distance Between Buoys A And B Than The Distance Between Buoys B And C?

Answers

Answer 1

Answer:

4

Step-by-step explanation:

1. the distance between A and B can be calculated:

[tex]|AB|=\sqrt{(4+4)^2+(-4-2)^2} =10.[/tex]

2. the distance between B and C can be calculated:

[tex]|BC|=\sqrt{(-4+4)^2+(2+4)^2} =6.[/tex]

3. if AB=10, BC=6, then difference between them is 4.

Answers

Step-by-step explanation:

√3sinA-cosA=√2

dividing both side by (√3²-1²=2 we get)

√3/2 sinA-1/2.cos A=√2/2

cos 30sinA-sin30cosA=√2/(√2×√2)

sinAcos30-cosAsin30=1/√2

sin(A-30)=sin45,sin(180-45)

therefore

A-30=45,135

A=45+30=75 or A=135+30=165

An experiment consists of ranomly drawing three cards in succession without replacement from a standard deck of 52 cards. Let A be the event of a king on the first draw, B the event of a king on the second draw, and C the even of a king on the third draw.

c. A ∩ B ∩ C
d. A U B U C

Answers

Answer:

0.0045248 ;

0.1312218 ;

0.0001809 ;

0.1659729

Step-by-step explanation:

Number of Kings in deck = 4

Total number of cards in deck = 52

Picking without replacement :

A = King on first draw :

P(A) = 4 / 52

A = King on 2nd draw :

P(B) = 3 / 51

A = King on 3rd draw :

P(C) = 2 / 50

1.) P(A n B) = P(A) * P(B)

P(A n B) = 4/52 * 3/51 = 12 / 2652 = 0.0045248

2.) P(A u B) = P(A) + P(B) - P(AnB)

P(AuB) = 4/52 + 3/51 - 0.0045248 = 0.1312218

3.) P(A ∩ B ∩ C) = P(A) * P(B) * P(C)

P(A ∩ B ∩ C) = 4/52 * 3/51 * 2/50 = 0.0001809

4.) P(A U B U C) =

P(A) + P(B) + P(C) - P(AnB) - P(AnC) - P(BnC) - P(AnBnC)

P(AnC) = P(A) * P(C) = 4/52 * 2/50 = 0.0030769

P(BnC) = P(B) * P(C) = 3/51 * 2/50 = 0.0023529

4/52 + 3/51 + 2/50 - 0.0045248 - 0.0030769 - 0.0023529 + 0.0001809 = 0.1659729

An isosceles right triangle has a hypotenuse that measures 32 inches. To the nearest inch,

what is the measure of each leg of the triangle?​

Answers

Answer:

28 inch  or 27.7 inch

other side is 16 inch

Step-by-step explanation:

We double the triangle and find each hypotenuse for two triangles to determine base as equilateral

32^2 = base

To find height we half base and multiply by slant = 32 inches

32/2 = 16 inch

Height = 32^2 - 16^2 = a^2  = sq rt 1024 - sqrt 256 = sq rt 768

a^2 = sq rt 768 = 27.7128129 = 28 inch  or 27.7 inch
