Find the area of the region bounded by the parabola y=5x2y=5x2, the tangent line to this parabola at (2,20)(2,20) and the xx axis.

1. Find the equation of tangent line at point (2,20).

The equation of the tangent line is

2. Express x:

3. Find the area of bounded region:

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour
