Answer: The product of 5 and a number

Step-by-step explanation:

The expression 5n represents the product of 5 and a number. For example, let the number be 8. Therefore, the value of the expression will be:

= 5n

= 5 × 8

= 40

The sum of 5 and a number will be:

= 5 + n

The difference of 5 and a number will be:

= 5 - n

What is the area of a parallelogram whose vertices are A(−12, 2) , B(6, 2) , C(−2, −3) , and D(−20, −3) ? Enter your answer in t
nikdorinn [45]

Let

A(-12,2)\\B(6,2)\\C(-2,-3) \\D(-20.-3)\\E(-12.-3)

using a graphing tool

see the attached figure to better understand the problem

we know that

Parallelogram is a quadrilateral with opposite sides parallel and equal in length

so

AB=CD \\AD=BC

The area of a parallelogram is equal to

A=B*h

where

B is the base

h is the height

the base B is equal to the distance AB

the height h is equal to the distance AE

Step 1

<u>Find the distance AB</u>

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

A(-12,2)\\B(6,2)

substitute the values

d=\sqrt{(2-2)^{2}+(6+12)^{2}}

d=\sqrt{(0)^{2}+(18)^{2}}

dAB=18\ units

Step 2

<u>Find the distance AE</u>

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

A(-12,2)\\E(-12.-3)

substitute the values

d=\sqrt{(-3-2)^{2}+(-12+12)^{2}}

d=\sqrt{(-5)^{2}+(0)^{2}}

dAE=5\ units

Step 3

<u>Find the area of the parallelogram</u>

The area of a parallelogram is equal to

A=B*h

A=AB*AE

substitute the values

A=18*5=90\ units^{2}

therefore

<u>the answer is</u>

the area of the parallelogram is 90\ units^{2}

Find all solutions to the differential equation dy dt = 1 − y 2
klemol [59]
Try this:
\frac{dy}{dt}=1-y^2; \ =\ \textgreater \  \   \frac{dy}{y^2-1}=-dt; \ =\ \textgreater \  \ ln| \frac{y-1}{y+1}|=-2t+C.
If it is possible, modify result to form more compact.
