Debora [2.8K]

Answer:

D) 35, 38, 41, 44, 47, 50,...

Step-by-step explanation:

The general term of an arithmetic sequence is

$t_n=32+3n$ , where n ∈N and n ≥ 1.

When n=1,

$t_1=32+3(1)=35$

When n=2,

$t_2=32+3(2)=38$

When n=3,

$t_3=32+3(3)=41$

When n=4,

$t_4=32+3(4)=44$

When n=5,

$t_5=32+3(5)=47$

When n=6,

$t_6=32+3(6)=50$

Hence the sequence is 35, 38, 41, 44, 47, 50,...

Malia is placing a barrier around the edge of a circular path with a diameter of 13 m. The barriers are in lengths of 2.5 m. Wha

emmainna [20.7K]

Let b be the number of barriers
so the circumference of the edge is C= 2 x r x π, the total of circumference is equal to the number of barriers, so C=2.5b, and then 2.5 b = 2 x r x π,
so b = 2 x r x π/2.5= 32.65, the approximative value is 33,
the answer is C. 33
