A rectangular page is designed to contain 81 square inches of print. The margins at the top and bottom of the page are each 1 in

Nookie1986 [14]

Answer:

x = 11.02 inch by y = 7.35 inch

Explanation:

Let the width of the print be = x

Then the width of the page is x + (1.5+1.5) = x + 3

Let the height of the print be = y

Then the height of the page is y + (1+1) = y + 2

Given the area of the print is 81 square inches

That means, xy = 81

Therefore, y = $\frac{81}{x}$

Therefore, the area of the page is

A = (x + 3)(y + 2)

= (x + 3)( $\frac{81}{x}$ + 2)

Now for least amount of paper to be used,

$\frac{dA}{dx}=(x+3)(\frac{81}{x}+2)$

$\frac{dA}{dx}= \left (\frac{81}{x}+2 \right )+\left ( x+3 \right )\left ( -\frac{81}{x^{2}} \right )=0$

$\frac{81+2x}{x}=\frac{(x+3)(81)}{x^{2}}$

$81x+2x^{2}=81x+81\times 3$

$2x^{2}=243$

x = 11.02 inch

Now y = $\frac{81}{x}$

= $\frac{81}{11.02}$

= 7.35 inch

Therefore the dimensions of thr page for the least amount of paper is x = 11.02 inch by y = 7.35 inch

Describe how a thermal inversion would form in the city

konstantin123 [22]

Thermal inversion.

A thermal inversion forms when a warm layer of air traps a cooler layer of air close to Earth's surface. The cold air ends up at the surface when the mountains block the morning sunlight from warming the floor of the valley or particulate pollution blocks sunlight from reaching the surface.

The increased aerosols in the urban atmosphere reduce the incoming solar radiation and increase the atmospheric longwave radiation in the urban areas. The response of the surface to the change of absorbed radiation is strong at night and weak during the day.

The warm air above cooler air acts like a lid, suppressing vertical mixing and trapping the cooler air at the surface. As pollutants from vehicles, fireplaces, and industry are emitted into the air, the inversion traps these pollutants near the ground, leading to poor air quality.

lubasha [3.4K]

Answer: Tationia Rolon

Explanation:The character that might have said this quote was the father of Anne Frank Otto Frank. In his statement I think he meant that if we keep bickering and arguing we are going to bring ourselves to destruction which basically means we are the true enemies to ourselves.I do agree with this statement because Mr.Frank was kind of like the glue in the Secret Annex whenever it started to get heated up he cooled it down.So I know he knows what he is doing.
