Since there is no figure attached, I will describe the derivation of the ideal gas law. The combined gas law has no official founder; it is simply the incorporation of the three laws that was discovered. The combined gas law is a gas law that combines Gay-Lussac’s Law, Boyle’s Law and Charle’s Law.  Boyle’s law states that pressure is inversely proportional with volume at constant temperature. Charle’s law states that volume is directly proportional with temperature at constant pressure. And Gay-Lussac’s law shows that pressure is directly proportional with temperature at constant volume. The combination of these laws known now as combined gas law gives the ratio between the product of pressure-volume and the temperature of the system is constant. Which gives PV/T=k(constant). When comparing a substance under different conditions, the combined gas law becomes P1V1/T1 = P2V2/T2.

Janeel has a 10-inch by 12-inch photograph. She wants to scan the photograph, then reduce the result
Vaselesa [24]

<u>Complete Question:</u>

Janeel has a 10 inch by 12 inch photograph. She wants to scan the photograph, then reduce the results by the same amount in each dimension to post on her Web site. Janeel wants the area of the image to be one eight of the original photograph. Write an equation to represent the area of the reduced image. Find the dimensions of the reduced image.

<u>Correct Answer:</u>

A) (10-x)(12-x)=15

B) Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch

<u>Step-by-step explanation:</u>

a. Write an equation to represent the area of the reduced image.

Let the reduced dimensions is by x , So the new dimensions are

length=10-x\\breadth=12-x

According to question , Area of new image is :

⇒ Area = \frac{1}{8}Length(breadth)

⇒ Area = \frac{1}{8}(10)(12)

⇒ Area = 15

So the equation will be :

⇒ (10-x)(12-x)=15

b. Find the dimensions of the reduced image

Let's solve :  (10-x)(12-x)=15

⇒ 120-10x-12x+x^2=15

⇒ 120-22x+x^2=15

⇒ x^2-22x+105=0

By Quadratic formula :

⇒ x = \frac{-b \pm \sqrt{b^2-4ac} }{2a}

⇒ x = \frac{22 \pm8 }{2}

⇒ x = \frac{22 +8 }{2} , x = \frac{22 -8 }{2}

⇒ x = 15 , x =7

x = 15 is rejected ! as 15 > 10 ! Side can't be negative

⇒ x =7

Therefore, Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch

Find the first three output values of the fractal generating function . –3 + 2i, –34 – 129i, 8354 + 7526i –3 + 2i, 2 – 10i, 8354
Dimas [21]

Fractal Generating Function, is

 f(z)=z²-3+2i

⇒f(0)=0²-3+2i

f(0)= -3+2i

⇒f(-3+2i)

  =(-3+2i)²-3+2i

 =9-4-12 i-3+2i

=2-10 i

⇒f(2-10i)

 =(2-10i)²-3+2i

 =4-100-40i-3+2i

 = -38 i-99

So, First three output values of the fractal generating function are

1.⇒ -3+2i

2. ⇒ 2-10 i

3.⇒-38 i -99

Remember

area of paralellogram is height times legnth of base
7.
height=18.7
legnth of base=6
area=18.7*6=112.2 yd^2

8.
height=5
leggnth of base=6
aera=5*6=30 m^2


10.
flip on side
height=7
legnth of base=15.1
area=7 times 15.1=105.7 ft^2

11.
height=10.2
legnth of base=14.2
area=14.2 times 10.2=144.84 cm^2

13.
height=18
legnth of base=19
area=18*19=342 in^2

14.
height=18
legnth of base=18
area=18*18=324 mi^2
