Answer: -5

Step-by-step explanation:

-5(x-5)=2(-4x+5)

-5x + 25 = -8x +10

3x +25 = 10 (add 8 from both sides)

3x = -15 (subtract 25 from both sides)

x = -5 (divide 3 from both sides)

H(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}h(n)=−91⋅(− 7 1 ​ ) n−1 h, left parenthesis, n, right parenthesis, equals
Kruka [31]

Given:

h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}

To find:

The recursive formula.

Solution:

We have,

h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}

It is in the form of explicate formula of a GP, .i.e., a_n=ar^{n-1}.

Here, a=-91 and r=-\dfrac{1}{7}.

The recursive formula of a GP is

a_n=a_{n-1}\times r

Using this the recursive formula for given problem is

h(n)=h(n-1)\times (-\dfrac{1}{7})

Therefore, the required recursive formula is h(n)=h(n-1)\times (-\dfrac{1}{7}).

A sum of $9, 000 paid into a bank account for two months (61 days) to attract simple interest will produce $9, 020 at the and of
Juliette [100K]

Answer:

Rate of interest will be 1.33 %

Return on this investment = =\frac{9020-9000}{9000}=0.222 %

Step-by-step explanation:

We have given principle amount P = $9000

Time = 61 days = \frac{61}{365}=0.167\ years

We have to find the rate of interest

Total amount produce at the end of term = $9020

So interest = $9020 - $9000 = $20

We know that simple interest =\frac{principle\ amount\times rate\times\ time}{100}

20=\frac{9000\times rate\times\\ 0.167}{100}

rate=1.33 %

Return on this investment = =\frac{9020-9000}{9000}=0.222 %
