the monthly budget for the front of the house is $18,000. you spent 9% of the budget on fresh flowers. How much did you spend on
Kipish [7]

To find how much was spent on fresh flowers, we just multiply 9% to the monthly budget, which is $18,000.

To multiply a percent to a number, we must first turn the percent into a decimal. Just divide the percent by 100 to get the decimal form. 9% is 0.09.

0.09 \times 18000 = 1620

$1620 was spent on fresh flowers (that's quite a lot of money!)

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}).
