P= 3in <br> a) find the length of each side of the square<br> b) find the area of the square
Anna007 [38]

Step-by-step explanation:

what does P mean ?

I assume it is perimeter ?

what is the perimeter of a square ?

come on, there is practically nothing in math that is easier to solve.

a square has 4 equal sides.

so, to go one time around the whole square, we have to go along every one of its 4 sides (which are all of equal length).

so, when I get the perimeter number, I know this is the result of all 4 sides added together.

and how can we express having 4 times the same number ? exactly how we say it in English : 4 times the number.

therefore

P = 4 × side length

and from there we can immediately deduct

side length = P / 4 = 3/4 in

now we know how long the sides of the square are.

what is the area of the square ?

like for any rectangle the area is length×width. just that length=width, so that we end up with length×length = length².

therefore, the area is

3/4 × 3/4 = (3/4)² = 9/16 in²

this is important : a length is measured e.g. in inches (in). an area is then measured in square-inches = in²

Answer:

in today's market supply and demand fluctuates. for example the recent demand for apple air pods. They came out in 2016 but were not very popular,But with the sudden increase in demand the amount sold has increased by 75 percent from 2017 to 2018. this could be graphed using the equation. f(x)=1.75x+16

with each unit on the graph equaling 1 million on the y axis

and the amount of years along the x but you must start at 16 along the x axis

in 2017 there was 16 million air pods sold and in December 2018 28 million were sold during that year

John Walters is comparing the cost of credit to the cash price of an item. If John makes a down payment of $160 and pays $35 a m
GREYUIT [131]

Answer:

The amount is $275 more that the cash price of $725.

Step-by-step explanation:

It is given that John makes a down payment of $160 and pays $35 a month for 24 months.

Down payment = $160

Total amount of installments = $35 × 24 = $840

Total amount of product = Down payment + Total amount of installments

Total amount of product = $160 + $840 = $1000

Cash price = $725

Difference between credit and cash price is

Difference = $1000 - $725 = $275

Therefore the amount is $275 more that the cash price of $725.

Please help me with this question.​
Evgen [1.6K]

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} } }}
