Triangle has an area of 54cm2 and a height of 9m. How long is the base?

Area = 54cm²

Height = 9m...

I want to believe you made a mistake in writing the unit for the height... Probably 9cm..

Comment if otherwise...

Area = 1/2 × base × height

54cm² = 1/2 × base × 9

Base = (54 × 2)/9

Base = 6×2

Base = 12cm....

Hope this helped...

A) Find a recurrence relation for the number of bit strings of length n that contain a pair of consecutive 0s.
Fed [463]

Answer:

A) a_{n} = a_{n-1} + a_{n-2} + 2^{n-2}

B) a_{0} = a_{1} = 0

C)   for n = 2

  a_{2} = 1

for n = 3

 a_{3} = 3

for n = 4

a_{4} = 8

for n = 5

a_{5} = 19

Step-by-step explanation:

A) A recurrence relation for the number of bit strings of length n that contain a  pair of consecutive Os can be represented below

if a string (n ) ends with 00 for n-2 positions there are a pair of  consecutive Os therefore there will be : 2^{n-2} strings

therefore for n ≥ 2

The recurrence relation for the number of bit strings of length 'n' that contains consecutive Os

a_{n} = a_{n-1} + a_{n-2} + 2^{n-2}

b ) The initial conditions

The initial conditions are : a_{0} = a_{1} = 0

C) The number of bit strings of length seven containing two consecutive 0s

here we apply the re occurrence relation and the initial conditions

a_{n} = a_{n-1} + a_{n-2} + 2^{n-2}

for n = 2

  a_{2} = 1

for n = 3

 a_{3} = 3

for n = 4

a_{4} = 8

for n = 5

a_{5} = 19

I need help. I’ll seriously make you brainly
ser-zykov [4K]

Answer:

a = 12

Step-by-step explanation:

add 2 to each side

5a/3 = a/4 + 17

distribute 12 to remove fractions

20a = 3a + 204

17a = 204

a = 12

Hello and it would be very helpful if you know these answers!
Wittaler [7]

Answer:

1) 15-4x

2) 3x+2

Step-by-step explanation:

1) product of x and 4 is 4x then subtract that from 15

2) use x as your age in this situation so your age times 3 is 3x and since he's 2 years older than that u add 2 more
