Answer:

Geometric, 81, 3

Step-by-step explanation:

A geometric sequence is defined as one that continues with multiplication.

We can tell that the sequence proceeds by multiplying 1/3.

a2 is 81 because it is the second term given in the sequence.

a5 is 3 because it equals a4 *1/3, which is 9*1/3 which is 3

<em>I hope this helps! :)</em>

What is the exact value of the expression the square root 72. − the square root of 8. + the square root of 128.? Simplify if pos
ivann1987 [24]
Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:

√72 - √8 + √128               separate the terms into square roots

√36·2 - √4·2 + √64·2        square root the terms that you can

6√2 - 2√2 + 8√2               they have like radical terms, so combine the terms

6 - 2 + 8 = 12                   the coefficients are 12 when combined

12√2                                 this is the EXACT VALUE of the expression

Hope this helps!

Sergio039 [100]

Answer:

Jerry will earn the same as Victoria in 9 years.

Step-by-step explanation:

Giving the following information:

Jerry:

Net income= 45,000 + 2,500x

Victoria:

Net income= 54,000 + 1,500x

x= number of years

<u>Now, we need to equal both formulas and isolate x:</u>

<u></u>

45,000 + 2,500x = 54,000 + 1,500x

1,000x = 9,000

x= 9

Jerry will earn the same as Victoria in 9 years.

<u>Prove:</u>

Jerry= 45,000 + 2,500*9= $67,500

Victoria= 54,000 + 1,500*9= $67,500
