Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
You Will Add Up All The Number Then Divide By The Total Number You Have In All
The Mean Is 185
You Put All The Number In Order For The Median
140,167,185,188,193,195,200,212
So You Have Two Number Which Are 188 and 195
You Will Add 188 + 195=383
Now You Divide 383 By 2 Which Is 191.5

Determine the coordinates of the centroid
Represent the coordinates with C.
C is calculated as follows:
Substitute values of x and y in the given equation
<em>The above is the coordinate of the centroid</em>
Answer:
<a = 90° (180-90 supplementary angle)
<b = 90° (180-90 supplementary angle)
<d = 48° (180-132 supplementary angle)
<e = 132° (opposite angle)
<c = 42° (interior angles of a triangle equal 180. 180-48-90=42)
Step-by-step explanation:
<a = 90° (180-90 supplementary angle)
<b = 90° (180-90 supplementary angle)
<d = 48° (180-132 supplementary angle)
<e = 132° (opposite angle)
<c = 42° (interior angles of a triangle equal 180. 180-48-90=42)
