Which formula should be used to find the length of EF?

A) x = -

b ± b2 - 4ac

2a

B) m =

y2 - y1

x2 - x1

C) M = (

x1 + x2

2

,

y1 + y2

2

)

D) d =

(x2 - x1)2 + (y2 - y1)2

because 1.2 isnt half of 6 duh

step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
