Answer:

\purple{ \boxed{\frac{d^{2} y}{dx ^{2} }   =    \frac{132}{ {x}^{13} } }}

Step-by-step explanation:

y =  \frac{1}{ {x}^{11} }  \\ y =  {x}^{ - 11}  \\  \frac{dy}{dx}  =  \frac{d}{dx}  {x}^{ - 11}  \\ \frac{dy}{dx}  =   - 11{x}^{ - 11 - 1}  \\ \frac{dy}{dx}  =   - 11{x}^{ - 12}  \\  \\  \frac{d}{dx}  \bigg(\frac{dy}{dx}  \bigg) =  \frac{d}{dx}  ( - 11 {x}^{ - 12} ) \\  \\ \frac{d^{2} y}{dx ^{2} }   =   - 11\frac{d}{dx}  ( {x}^{ - 12} ) \\  \\ \frac{d^{2} y}{dx ^{2} }   =   - 11(  - 12{x}^{ - 13} ) \\  \\ \frac{d^{2} y}{dx ^{2} }   =   132{x}^{ - 13} \\  \\  \huge \red{ \boxed{\frac{d^{2} y}{dx ^{2} }   =    \frac{132}{ {x}^{13} } }}

An online shopping club has 10,000 members when it charges $7 per month for membership. For each $1 monthly
Sonja [21]

Answer:

The function that can be used in the online shopping club about its monthly revenue is:

R = -400x^{2} +7200x+70000

Step-by-step explanation:

First, we're gonna take into account the different values we have in the exercise:

  1. 10,000 members
  2. $7 per month for membership
  3. Loses of 400 members by each $1 monthly increase

How the variable x represents the price increase, we can do the formula below:

  • (10000 - 400x) * (7+x)

In this formula, we represent in the first part that by each 1 in the variable x, the total of members will be reduced in 400, in the second part, we mention that at the same time, the membership fee will be increased in the same value of x. Now we must simplify this function:

  • (10000 - 400x) * (7+x)

We operate the values:

  • 70000+10000x-2800x-400x^{2}

Solve we can:

  • 70000+7200x-400x^{2}

And organize:

  • -400x^{2} +7200x+70000

At the end, how R represents the monthly revenue received by the club, we use that variable for our formula:

  • R=-400x^{2} +7200x+70000

Principal = 5300=5300 rupees
PSYCHO15rus [73]

Answer:

Using the formula:

A=P+I

where

A is the total amount

P is the principal

I is the Simple Interest

As per the statement:

Principal(P) = 5300 rupees.

rate of interest(r) = 6.5% = 0.065

Total amount(A) = 6678 rupees.

Then using above formula we have;

6678 = 5300+I

Subtract 5300 both sides we get;

1378 = I

or

I = \$1378

We have to find the time period.

Using formula of Simple interest:

I = Prt

where r is the rate of interest (in decimal)

here, r = 6.5% = 0.065

Substitute the given values top find t:

1378 = 5300 \cdot 0.065 \cdot t

⇒1378 = 344.5t

Divide both sides by 344.5 we have;

4  = t

Therefore, the time period t in years is 4 years
