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.

20-9x=11
-9x=11-20
-9x= -9
x= -9/(-9)
x=1

4(2x+1)=8
2x+1=8/4
2x+1=2
2x=2-1
2x=1
x=1/2
x=0.5

5(2x+5)=-15
2x+5= -15/5
2x+5= -3
2x= -3-5
2x= -8
x= -8/2
x=-4

3(8x+1)=-21
8x+1= -21/3
8x+1= -7
8x= -7-1
8x =-8
x= -8/8
x= -1

What is the answer, Shelby made 5 quarts of juice for a picnic. How many cups of juice did shelby make?

Given, Shelby made 5 quarts of juice for a picnic.

We know that 1 quart of juice = 4 cups of juice.

Here we will have to convert 5 quarts to cups.

As for 1 quart there are 4 cups, to find 5 quarts we have to multiply 4 times 5.

So 5 quarts of juice = $(4)(5)$ cups of juice.
