What is the distance between points (9,-7) and (9,4) on a coordinate plane

Step-by-step explanation:

The distance formula is d=√x2 - x1²+ y2 - y1².

The first thing to do is substitute the numbers we have into this formula.

d=√9 - 9²+ 4 - -7²

d=√0² + 11²

d = d=√0 + 121

d = d=√121

d = 11

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
