Martha is taking her pulse. The table shows the number of heartbeats Martha counts in a given amount of time. What equation in slope-intercept form gives Martha's heartbeats after x seconds? Use your equation to find the number of heartbeats Martha will have in 2 minutes. A. y=74x; 210 beats B. y=47x; 210 beats
C. y−35=74(x−20); 105 beats
D. y=74x; 105 beats

5/20 so 25%

step-by-step explanation:

the answer is a.

135 and 80

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
