Current Amount = Starting Amount (1 + rate of change)^number of months
350 = 200 ( 1 + r)^5
350/200 = (1+r)^5
sqrt5 (350/200) = 1+r
sqrt5 (350/200) - 1 = r

1 2/7 +2 1/3x +3/14+x=9
Genrish500 [490]

Answer:

9/4

Step-by-step explanation:

1 2/7=9/7

2 1/3=7/3

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

9/7+7/3x+3/14+x=9

18/14+3/14+7/3x+3/3x=9

21/14+10/3x=9

10/3x=9-21/14

10/3x=9-3/2

10/3x=18/2-3/2

10/3x=15/2

x=(15/2)/(10/3)

x=(15/2)(3/10)

x=45/20

simplify

x=9/4

Convert the decimal expansion 0.1777 into a rational number
Helen [10]

Answer:

The rational form of the given number 0.1777  = \frac{1777}{10,000}

Step-by-step explanation:

The rational number is expressed as a number on the form of (\frac{p}{q} ) , q \neq 0

Now,here the given number in decimal form = 0.1777

To remove the decimal, firstly count the number of digits AFTER DECIMAL.

Here, number of digits after decimal = 4

SO, the decimal can be removed and replaced by 1 , by dividing with 1,0000.

\implies 0.1777  = \frac{01,777} {10,000}  = \frac{1777}{10,000}

Hence, the rational form of the given number 0.1777  = \frac{1777}{10,000}

, list the first five terms of each sequence.<br> f(n + 1) = −2f(n) + 8 and f(1) = 1 for n ≥ 1
svet-max [94.6K]

Answer: 1, 7, 1, 7, 1.

Step-by-step explanation:

The given function :  f(n+1)=-2f(n)+8 and  f(1) = 1 for n ≥ 1

We put value of n=1,2,3,4 , we get

For n=1  , f(2)=f(1+1)=-2f(1)+8=-1(1)+8=-1+8=7

For n=2  , f(3)=f(2+1)=-2f(2)+8=-1(7)+8=1

For n=3  , f(4)=f(3+1)=-2f(3)+8=-1(1)+8=7

For n=4  , f(5)=f(4+1)=-2f(4)+8=-1(7)+8=1

Hence, the  first five terms of the given sequence are 1, 7, 1, 7, 1.
