Does the following infinite series converge or diverge?

1 answer:

3 0

Look like that first one is supposed to have a denominator of 2.

This is a geometric series with a common ratio 4, so it diverges (absolute value 1 or more), meaning it has no sum. Choice C.

Select proportional or not proportional to correctly classify the pair of ratios. 1.2/3 and 1.8/4.5

Gnesinka [82]

Answer:

Proportional.

Step-by-step explanation:

Find the cross products. If they are same, then they are proportional.

$\dfrac{1.2}{3} = \dfrac{1.8}{4.5}$

Cross multiply,

1.2 * 4 .5 = 3*1.8

5.40 = 5.4

So, they are proportional.

Multiply the numerator and denominator of 1.2/3 by 1.5

$\dfrac{1.2*1.5}{3*1.5}=\dfrac{1.8}{4.5}$

From this we come to know they are proportional

1.2 : 3 :: 1.8 : 4.5

Product of means = 3*1.8 = 5.4

Product of extremes = 1.2*4.5 = 5.4

Product of means = product of extremes. So, they are proportional.

Answer:

The equation 2d + 18 = 24 can help find the number of days Jerry has been doing sit-ups.

Step-by-step explanation:

During the first day, Jerry did 18 sit-ups, and he proceeded to do 2 more sit-ups each following day, so the expression to represent this situation is 2d + 18. Because he did 24 sit-ups today, to find the number of days he did sit-ups, the equation to solve is 2d + 18 = 24.
