The first term in a sequence of numbers is 1/2
Andrei [34K]

Answer:

The correct answer is C. The 4th term is 11.

Step-by-step explanation:

Since the next term is one more than twice the previous, we can calculate it by the following expression:

a_{n} = 2*a_{n-1} + 1

So the second term is:

a_2 = 2*\frac{1}{2} + 1\\a_2 = 2

The third term:

a_3 = 2*2 + 1\\a_3 = 5

And the fourth term:

a_4 = 2*5 + 1\\a_4 = 10 + 1 = 11

The correct answer is C. The 4th term is 11.

A box measures 3 1/2 ft by 1 1/3 ft by 2/14 ft what is the volume
asambeis [7]

Answer: 2/3^3

Step-by-step explanation:

To find the volume of a box, you use the formula, Lenth*Width*Height=Volume

The Lenth is 3 1/2. The width is 1 1/3 and the height is 2/14

Plug the values in formula

3 1/2*1 1/3*2/14

Covert the mixed numbers into imporper fractions so it is easier to solve

3 1/2=7/2

1 1/3=4/3

7/2*4/3*2/14

Reduce 2/14

2/14=1/7

7/2*4/3*1/7=7*4*1/(2*3*7)=28/42

Reduce 28/42=14/21=2/3

2/3 ft^3

Find x<img src="https://tex.z-dn.net/?f=log_%7B8%7Dx%3D4%2F3" id="TexFormula1" title="log_{8}x=4/3" alt="log_{8}x=4/3" align="ab
MArishka [77]
I will assume the question is log (8x) = 4/3

This means, "The exponent we put on 10 to get 8x is 4/3"

10^(4/3) = 8x

x = [10^(4/3)]/8

x = 2.69


log (8*2.69) = 4/3 ?
log (21.52) = 4/3
1.33 = 4/3
1.33 = 1.33
