Answer:

yes, it is possible to have the sum of square roots equal the square root of the sum of the radicands.

If either a or b equals zero, then the sums would be the same.

Since the square root of 0 is 0, adding it to a given radical would not change the radical. Also adding zero to the radicand would not change its value.


these are the right answer for E2020

A house worth $70,000 when purchased was worth $67,000 after the first year and $64,000 after the second year. If the economy do
Citrus2011 [14]

Answer:

a) The formula for the sequence is

a_n = 67,000 -3,000(n-1)

b) a_7 = 49,000

Step-by-step explanation:

Note that the difference between any two consecutive terms in the sequence is always equal to $3,000

67,000-70,000= -3,000\\\\64,000-67,000=-3,000

Then we have an arithmetic sequence where each term increases by a magnitude of 3,000 with respect to the previous term.

The explicit formula for an arithmetic sequence is:

a_n = a_1 +d(n-1)

Where d is the common difference between the consecutive terms of the sequence

d = -3,000

a_1 is the first term, or the value of the house after year 1 a_1= 67,000

n represents the number of years since the house was purchased

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

a) Then the formula for the sequence is

a_n = 67,000 -3,000(n-1)

With

n={0, 1, 2, 3, 4, 5, 6, 7,.., n}

---------------------------------------------------------------------------------------------

b) Now we can use the formula to find the price of the house after 7 years

a_7 = 67,000 -3,000(7-1)

a_7 = 67,000 -3,000(6)

a_7 = 49,000
