Answer:

Step-by-step explanation:

9) to determine x, we would apply the sine rule which is expressed as

a/SinA = b/ SinB = c/SinC

Therefore,

12/Sin95 = 8/Sinxx

Cross multiplying, it becomes

12Sinx = 8Sin95 = 8 × 0.9962

Sinx = 7.9696/12 = 0.6641

x = Sin^-1(0.6641)

x = 41.61°

10) we would apply the cosine rule. It is expressed as

a² = b² + c² - 2abcosA

Therefore,

x² = 6² + 8² - 2 × 6 × 8 × Cos 100

x² = 36+ 64 - 96 × - 0.1736

x² = 100 + 16.6656 = 116.6656

x = √116.6656

x = 10.8

Answer:

The answer to your question is below

Step-by-step explanation:

Number 9.

To find x use the law of sines

                   sin x / 8 = sin 95 / 12

Solve for sin x

                   sin x = 8 sin 95 / 12

                   sin x = 0.664

                        x = 41.6°

Number 10

To find x use law of cosines

                    x² = 6² + 8² - 2(6)(8)cos100

                    x² = 36 + 64 - 96(-0.174)

                    x² = 100 + 16.67

                    x² = 116.67

                   x = 10.80

Suppose that you can only use the set of small letters characters (a-z) and odd numbers (1, 3, 5, 7, 9) to set a password. What
Flauer [41]

Answer:

31^8

Step-by-step explanation:

To create a password, you need to select 8 characters (not necessarily different) from the set {1,3,5,7,9,a,b,c,...,z}. Now, this set has 31 elements: the 26 lowercase letters from the alphabet and the 5 odd numbers (1,3,5,7,9).

Now, there are 31 ways to choose the first character, it can be any element from our set. The second character can also be chosen in 31 ways, because there are not restrictions (repetitions, specific characters, etc). Similarly, the third, fourth, fifth, sixth, seventh and eighth characters have 31 possibilities each one.

The number of passwords is the number of ways of selecting the 8 characters, then by the multiplication principle the number of passwords is 31×31×31×31×31×31×31×31=31^8.

If f(x)=x-2 and g(x)=1/2x, find g(f(x))
Scilla [17]

Answer:

hello :

If f(x)=x-2 and g(x)=1/2x,

g(f(x)) = g ( x - 2 )

          = 1/2(x-2)

g(f(x)) = (1/2)x - 1
