Triunghiurile ABC și DBC sunt dreptunghice, ∢A = ∢D = 90° și E este mijlocul laturii BC. a) Dacă punctele A, E, D nu sunt coliniare, demonstrați că triunghiul triunghiul AED este isoscel. b) Dacă AD⊥ BC, arătați că Δ ABC ≡ Δ DBC. dau corona

(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

what do you mean

have a great day

the one where 1 and 2 are directly across from each other.

transitive property

step-by-step explanation:

the definition of the transitive property is:

if a = b, and b = c, then a = b
