I need help plz pt.2​
Fynjy0 [20]

Answer:

See explanation

Step-by-step explanation:

Consider the sequence \dfrac{1}{32},\ \dfrac{1}{8},\ \dfrac{1}{2}, 2,\ 8,...

Rewrite it as

b_1=\dfrac{1}{32},\\ \\b_2=\dfrac{1}{8},\\ \\b_3=\dfrac{1}{2},\\ \\b_4=2,\\ \\b_5=8...

The points on the coordinate plane are

(1,b_1),\ (2,b_2),\ (3,b_3),\ (4,b_4),\ (5,b_5),... (see attached graph).

Since

4=\dfrac{b_2}{b_1}=\dfrac{b_3}{b_2}=\dfrac{b_4}{b_3}=\dfrac{b_5}{b_4}..., given sequence is geometric.

Dana walks 3/5 mile in 1/4 hour. What is dana's walking rate in miles per hour?
Flura [38]
Here, our equation is 3/5 (0.6) mile per 1/4 (0.25) hour.  0.25 times 4 = 1, so we have to multiply 1/4 (0.25) 4 times to get 1 mile. To get a proportional answer, we must also multiply 3/5 (0.6) by 4. This comes out to 2.4. So her walking rate is 2.4 miles per hour.
