A median of a triangle is a segment joining any vertex of the triangle to the midpoint of the opposite side. All triangles have three medians, which, when drawn, will intersect at one point in the interior of the triangle called the centroid. The centroid of a triangle divides the medians into a 2:1 ratio.

Let A be the area of a circle with radius r. If dr/dt=3, find dA/dt when r=2.

astraxan [27]

$\bf \textit{area of a circle}=A=\pi r^2
\\\\\\
\cfrac{dA}{dt}=\pi \cdot 2r^1\cdot \cfrac{dr}{dt}\implies \cfrac{dA}{dt}=\pi \cdot 2r\cdot \cfrac{dr}{dt}\quad 
\begin{cases}
r=2\\
\frac{dr}{dt}=3
\end{cases}
\\\\\\
\cfrac{dA}{dt}=\pi \cdot 2(2)(3)$

Answer:

x = 4
WX = WY = 25
XY = 17

Step-by-step explanation:

The triangle is isosceles with side WX equal to side WY:

WX = WY

9x -11 = 7x -3

2x = 8 . . . . . add 11-7x

x = 4

Then the side measures are ...

WX = WY = 7(4) -3 = 28 -3 = 25

XY = 4(4) +1 = 16 +1 = 17
