Answer:
a(n) = a(n - 1) - 4, with a(1) = 19
Step-by-step explanation:
If the rule for finding each new term is "take away 4," then this is an arithmetic sequence with first term a(1) (unknown) and third term 11. The "common difference" is -4.
Then the formula for this arithmetic sequence is found as follows:
The third term is 11. The previous (second) term is 4 greater, or 15. The first term (coming before 15) is 19.
Thus, the general formula is
a(n) = a(n - 1) - 4, with a(1) = 19
Check: Does a(1) come out to 19? Is 19 - 4(1 - 1) = 19? YES
Does a(2) come out to 15? Is 19 - 4 = 15? YES
Does a(3) come out to 11? Is 15 - 4 = 11? YES
Answer:
The fraction 58/60 is equal to 29/30 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (29/30) by any interger number, ie, multiply by 2, 3, 10, 30... 58/60 is equivalent to 29/30 because 29 x 2 = 58 and 30 x 2 = 60

Dont know if this helps but i hope it does!
We are given with the principal amount of <span> $1 million and is asked in the problem to calculate for the money supply given the reserve ratio is 15%. The formula that is applicable to this problem is F = P / r where P is the principal amount, r is the ratio and F is the future/ money supply. In this case, upon substitution, F = $1 m million / 0.15 = $6.67 million. The money put into reserve is expected to increase after putting into reserve. The lower the reserve ratio, the higher the money supply will be. Conversely, the higher the principal amount, the higher the money supply.</span>
Estimate -6.1(0.22)
Answer:
Use rounding to get -6(0.2), and then multiply.
Use front-end estimation to get -6(0.2), and then multiply.
