Mathematics
1 answer:
Naya [18.7K]3 years ago

Answer:

21 miles

Step-by-step explanation:

This is a two part problem, first, use triangle BAC to get your Angle A.

Angle A = 23.6

Length AB = 2√305

Now plug in your Angle A and find Angle B which is 66.4

The sum of all the angles in a triangle is 180

23.6+90+B=180

Then find Length AD

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.

sin(B) = opp/hyp

sin(B) = 48 / AD

AD = 48/sin(66.4)

AD = 52.3

Now find last side DE of the triangle using the Pythagorean theorem.

DE^2 + AE^2 = AD^2

DE^2 = AD^2 - AE^2

DE^2 = 52.3^2 - 48^2

DE = 20.97

It has to be the 2 and 3 because when you multiply fractions you use keep change flip for example 2/3 divided by 2/3 you keep the first fraction 2/3 you change division to multiplication and you flip the last fraction which will be 2/3x3/2

Recursive definitions for subsets of binary strings.Give a recursive definition for the specified subset of the binary strings.
dmitriy555 [2]

Answer:

Step-by-step explanation:

A binary string with 2n+1 number of zeros, then you can get a binary string with 2n(+1)+1 = 2n+3 number of zeros either by adding 2 zeros or 2 1's at any of the available 2n+2 positions. Way of making each of these two choices are (2n+2)22. So, basically if b2n+12n+1 is the number of binary string with 2n+1 zeros then your

b2n+32n+3 = 2 (2n+2)22 b2n+12n+1

your second case is basically the fact that if you have string of length n ending with zero than you can the string of length n+1 ending with zero by:

1. Either placing a 1 in available n places (because you can't place it at the end)

2. or by placing a zero in available n+1 places.

0 ϵ P

x ϵ P → 1x ϵ P , x1 ϵ P

x' ϵ P,x'' ϵ P → xx'x''ϵ P

22. 30 = 2 * 3 * 5

23. 126 = 2 * 3 * 3 * 7

24. 4900 = 2 * 2 * 5 * 5 * 7 * 7

25. 39204 = 2 * 2 * 3 * 3 * 3 * 3 * 11 * 11

26. There's no square number

27. The highest common factor are

   30 is 5

   126 is 7

  4900 is 7

 39204 is 11

28. The lowest common factor are

 30 is 2

 126 is 2

 4900 is 2

 39204 is 2
