Answer:

D. The only factors of 11 and 1 are 11.

Step-by-step explanation:

Factors are the numbers you multiply together to get another number.

1, 2, 4 and 8 are factors of 8.

1, 3, and 9 are factors of 9.

1, 2, 5, and 10 are factors of 10.

11 is the only number of the four that has only two factors: 1 and 11

Given the sequence 4, 8, 16, 32, 64, ..., find the explicit formula.

Goshia [24]

Answer:

$\sf 2^{(n+1)}$

Step-by-step explanation:

Explicit formula is used to represent all the terms of the geometric sequence using a single formula.

$\sf \boxed{\bf t_n=ar^{(n-1)}}$

Here, a is the first term.

r is the common ratio.

r = second term ÷ first term

4, 8,16,32,64,.....

a = 4

r = 8 ÷4 = 2

$\sf t_n =4*2^{(n-1)}$

$\sf = 4*2^n * 2^{(-1)}\\\\ = 4*2^n*\dfrac{1}{2}\\\\ = 2*2^n$

$\sf = 2^{(n+1)}$

I forget how to do this,thanks for the help!

miss Akunina [59]

Answer:

x=12

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

5x+8x+2x =180

Combine like terms

15x = 180

Divide by 15 on each side

15x/15 =180/15

x=12
