Answer:

T^2*g / 4pi^2 = l

Step-by-step explanation:

T = 2 * pi * sqrt( l/g)

We need to solve for l

Divide each side by 2pi

T/ (2pi) = 2 * pi/2pi * sqrt( l/g)

T/ (2pi) = sqrt( l/g)

Now square each side

(T/ (2pi))^2 = ( sqrt( l/g))^2

T^2 / 4pi^2 = l/g

Multiply each side by g

T^2 / 4pi^2 * g= l/g*g

T^2*g / 4pi^2 = l

Fleece vests regularly priced at $15.99 are on sale for $13.99. If the sales tax is 5%, how much can you save by buying the vest

Marysya12 [62]

Saving of $2.10 is made by buying fleece vest on sale.

<u>Solution:</u>

Given that regular price of fleece vest = $15.99

And sale price of fleece vest = $13.99

Sales tax = 5%

When we buy at regular price, total amount including sales tax which needs to be paid is:

$\mathrm{A}_{\mathrm{R}}$ = 15.99 + 5% of 15.99

$\begin{array}{l}{\mathrm{A}_{\mathrm{R}}=15.99+5 \times \frac{15.99}{100}} \\\\ {\mathrm{A}_{\mathrm{R}}=15.99\left(\frac{105}{100}\right)=15.99 \times 1.05}\end{array}$

When buy at sales price, total amount including sales tax which needs to be paid that is

$\begin{array}{l}{\mathrm{A}_{\mathrm{S}}=13.99+5 \% \text { of } 13.99} \\\\ {\mathrm{A}_{\mathrm{S}}=13.99+5 \times \frac{13.99}{100}} \\\\ {\mathrm{A}_{\mathrm{S}}=13.99\left(1+\frac{5}{100}\right)} \\\\ {\mathrm{A}_{\mathrm{S}}=13.99\left(\frac{105}{100}\right)=13.99 \times 1.05}\end{array}$

$\text { Saving made }=\mathrm{A}_{\mathrm{R}}-\mathrm{A}_{\mathrm{S}}$

$\begin{array}{l}{=(15.99 \times 1.05)-(13.99 \times 1.05)} \\\\ {=1.05(15.99-13.99)} \\\\ {=1.05 \times 2=\$ 2.10}\end{array}$

Hence saving of $2.10 is made by buying fleece vest on sale.

The number of tree species s in a given area a in the pasoh forest reserve in malaysia has been modeled by the power function s(

jolli1 [7]

$s(a) = 0.882 a^{0.842}$

s'(107) means the value of derivative of s(a) at a = 107. So, first step is to find the derivative of s(a).

$s(a) = 0.882 a^{0.842}$
Taking derivative of both sides, we get:
$\frac{d}{da}(s(a))= \frac{d}{da}( 0.882 a^{0.842})$

Taking the common out from right hand side of the equation:
$s'(a)= 0.882\frac{d}{da}(a^{0.842})$

Applying the power rule of derivative:

$s'(a) = 0.882 ( 0.842 a^{(0.842-1)}) \\ s'(a) = 0.742644 a^{-0.158}$

Now we can substitute 107 in place of a to get s'(107):
$s'(107) = 0.742644( 107)^{-0.158} \\ s'(107)= 0.35494$

Thus the value of s'(107) rounded to 5 decimal places is 0.35494
