Answer:
50,076 square inches
Step-by-step explanation:
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:
Not sure but 2 would be the same as 1 so 39.5 and 3 and 4 would be 50.5
Step-by-step explanation:
1 and 3 make a right angle and so does 4 and 2 so all I did was subtract 39.5 from 90 since a right angle=90 degrees
The answer is B cause I love mathematics.
