Here is a pattern made from sticks: a)How many sticks would be in pattern 6? b) How many sticks would be in pattern number n?
Wittaler [7]

Answer:

a) 26

b) 4n+2

Step-by-step explanation:

From the given figure it is clear that,

Number of sticks in pattern 1 = 6

Number of sticks in pattern 2 = 10

Number of sticks in pattern 3 = 14

Now,

6, 10, 14, ...

It is an AP.

Here, first term = 6

Common difference  = 10 - 6 = 4

nth term of an AP is

a_n=a_1+(n-1)d

where, a_1 is first term and d is common difference.

So, nth term of given AP is

a_n=6+(n-1)4

a_n=6+4n-4

a_n=4n+2

Now, substitute n=6 in the above equation to find the number of sticks in pattern 6.

a_n=4(6)+2=24+2=26

Therefore, the number of sticks in pattern 6 is 26.

Since a_n=4n+2, therefore, the number of sticks in pattern n is 4n+2.

A ladder leans against a side of a building, making a 63-degree angle with the ground, and reaching over a fence that is 6 feet
zhenek [66]

Answer:

The answer to your question is 10 ft

Step-by-step explanation:

Data

Adjacent side = b = 6 ft

Opposite side = a = 8 ft

Hypotenuse = c = ?

angle = 63°

Process

1.- Use the Pythagorean theorem to find the length of the ladder.

                 c² = a² + b²

- Substitution

                 c² = 8² + 6²

-Simplification

                 c² = 64 + 32

                 c² = 100

                 c = \sqrt{100}

- Result

                c = 10 ft

2.- Conclusion

The ladder has a length of 10 ft
