Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown

Naily [24]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -17}}\quad ,&{{ 7}})\quad 
% (c,d)
&({{ x}}\quad ,&{{ y}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)$

$\bf \left( \cfrac{x-17}{2}~,~\cfrac{y+7}{2} \right)=\stackrel{\textit{midpoint}}{(-23,10)}\implies 
\begin{cases}
\cfrac{x-17}{2}=-23\\\\
x-17=-46\\
\boxed{x=-29}\\
----------\\
\cfrac{y+7}{2}=10\\\\
y+7=20\\
\boxed{y=13}
\end{cases}$

In quadrant 2 , x is ? and y is ?

Bezzdna [24]

In quadrant 2, x is negative which means x < 0. Also, in quadrant 2, y is positive so y > 0.

An example point that is located in quadrant 2 is the point (-5, 8). Note how the first coordinate is -5 so x = -5 which is negative. Furthermore, the second coordinate is 8 meaning that y = 8 which is positive.

Quadrant 2 is the quadrant on the upper left-hand side of the four quadrants on the xy coordinate system.

Find the volume of a right circular cone that has a height of 16 m and a base with a

anzhelika [568]

Answer:

The volume of a right circular cone that has a height of 16 m and a base with a circumference of 14.7 m is 3,620.62 m³

Step-by-step explanation:

The right cone (or cone of revolution, or right circular cone) is the solid of revolution formed by rotating a right triangle around one of its legs. The bottom circle of the cone is called the base. That is, a cone is a three-dimensional figure with a circular base. A curved surface connects the base and the vertex.

The volume of a 3-dimensional solid is the amount of space it occupies.

The volume V of a cone with radius r is one-third the area of the base B times the height h. This is:

$V=\frac{1}{3}*A*h$

where A=π*r²

Then: V= $\frac{1}{3}$ *π*r²*h

In this case r=14.7 m and h=16 m. Replacing:

V= $\frac{1}{3}$ *π*(14.7 m)²*16 m

Solving, you get:

V=3,620.62 m³

The volume of a right circular cone that has a height of 16 m and a base with a circumference of 14.7 m is 3,620.62 m³
