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 rectangle with an area of 3990 cm2 is x centimeters wide and (x+4) centimeters long. To the nearest tenth of a centimeter, the

Karolina [17]

Answer: width:60.2 cm

Length: 64.2 cm

Step-by-step explanation:

Given

The area of the rectangle is $3990\ cm^2$

Width of the rectangle is $x\ cm$

Length of the rectangle is $x+4\ cm$

Area of the rectangle is the product of length and width

$\therefore 3990=(x+4)x\\\Rightarrow 3990=x^2+4x\\\Rightarrow x^2+4x-3990=0\\\Rightarrow x=60.198\ or\ -65.198\ cm\\\text{Neglecting negative term}\\\Rightarrow x=60.198\approx 60.2\ cm$

Width of the rectangle is $60.2\ cm$

Length of the rectangle is $60.2+4=64.2\ cm$
