Answer:

The phrasing of the question is weird, but the mass should not change. The scale may read higher for a moment, but once the mass is brought up to the same velocity of the elevator, it should settle back to 100.

In a thunderstorm, the wind velocity in meters per second can be described by the function v(p) = 5.7 √998 - p, where p is the a
nataly862011 [7]

Answer:

923.1927 millibars

Step-by-step explanation:

The wind velocity is given by the function:

v(p)=5.7\sqrt{(998-p}

#We make p the subject of the formula:

v(p)=5.7\sqrt{(998-p}\\\\v=5.7\sqrt{(998-p}\\\\\frac{v}{5.7}=\sqrt{(998-p}\\\\\frac{v^2}{5.7^2}=998-p\\\\p=998-\frac{v^2}{5.7^2}

#Substitute the given values in the function above to solve for p;

p=998-\frac{v^2}{5.7^2}\\\\=998-\frac{49.3^2}{5.7^2}\\\\=923.1927\ millibars

Hence, the air pressure is 923.1927 millibars.

Coby needs to know the area and perimeter of his farm property. The length of his property is 1 6 mile and the width is 2 9 mile
Alexandra [31]

Answer:

P= 7/9 miles

A= (7/18) miles²

Step-by-step explanation:

Length 'l' = (1/6) mile

Width 'w'= (2/9) mile

Perimeter 'P' is given by:

'P' = 2l + 2w => 2(1/6) + 2(2/9)

P= 7/9 miles

Area 'A' is given by:

A= l x w =(1/6) x (2/9) = (7/18) miles²
