C= pi x 2r
C=pi x diameter
D=2r
Answer:
Step-by-step explanation:
given a point the equation of a line with slope m that passes through the given point is
or equivalently
.
Recall that a line of the form , the y intercept is b and the x intercept is .
So, in our case, the y intercept is and the x intercept is .
In our case, we know that the line is tangent to the graph of 1/x. So consider a point over the graph . Which means that
The slope of the tangent line is given by the derivative of the function evaluated at . Using the properties of derivatives, we get
. So evaluated at we get
Replacing the values in our previous findings we get that the y intercept is
The x intercept is
The triangle in consideration has height and base . So the area is
So regardless of the point we take on the graph, the area of the triangle is always 2.
Answer:
30
Step-by-step explanation:
3 pieces each 1 dekameter long
1 dekameter = 10 meters
Convert dekameters to meters
3 pieces each 10 meters long
Multiply
Glenn has 30 meters of lanyard
Divide
He can cut 30 1-meter pieces
Hope this helps :)
