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.

(x - 2)2 + (y + 3)2 =1). What is the radius ?

tia_tia [17]

Answer:

radius = 1

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 2)² + (y + 3)² = 1 ← is in standard form

with r² = 1 ( take the square root of both sides )

r = $\sqrt{1}$ = 1

A cylinder has a height of 6 meters and a radius of 3 meters. What is its volume? Use ≈ 3.14 and round your answer to the near

bija089 [108]

Answer:

169.56 m³

Step-by-step explanation:

» Concepts

The volume of a cylinder is how much space there is inside the cylinder. The formula to find the volume is πr²h, where r = radius and h = height. Once you get the volume, you have to add <unit>³.

» Application

We are given the radius as three meters and the height as six meters; we also have to use π as 3.14. Now, we just have to plug in these values into the aforementioned formula.

» Solution

$3.14*3^3*6$
$3.14*9*6$
$28.26*6$
$169.56$
