First we have to find the tangent line:
y - y o = f ` ( x o ) * ( x - x o )
f ` ( x ) = 10 x
y - 80 = 40 ( x - 4 )
y = 40 x - 160 + 80
y = 40 x - 80
There are 2 parts of this region:
A =
A = 40/3 + 320/3 - 320 + 320 - 40/3 + 80 - 160 = 320/3 - 240/3 =
80/3
Answer:
y = 3/5x - 1
Step-by-step explanation:
The slope found from counting the units is 3/5, and the y-intercept is -1, hence 3/5x - 1
Step-by-step explanation:
By Geometric mean property:
Thus, option A) 4√3 is the correct answer.
15 miles per hour
Multiply by (5,280 / 3,600)
15 * (5,280 / 3,600) = 22 feet per second
