​ABCD is an inscribed polygon. Given mBCD=2(m∠A) - Response area
mDAB=2(m∠C) - Inscribed Angle Theorem mBCD+mDAB=360°
2(m∠A)+2(m∠C)=360° - Response area
​m∠A+m∠C=180°​ - Division Property of Equality ​​
∠A and​∠C​ are supplementary angles. - Response area

(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

no its the same as every other grade

step-by-step explanation:

b is the right answer
