Answer:
Expression Derivatives
y = tan-1(x / a) dy/dx = a / (a2 + x2)
y = cot-1(x / a) dy/dx = - a / (a2 + x2)
y = sec-1(x / a) dy/dx = a / (x (x2 - a2)1/2)
y = cosec-1(x / a) dy/dx = - a / (x (x2 - a2)1/2)
Answer:
9(1-4x)
Step-by-step explanation:
To answer this first we set up a proportion and then solve. Lets do it:-

Cross Multiply:-
80 · 4 = 320
Divide:-
420 ÷ 12 = 60
So, 180 ears of corn are for
$60.Hope I helped ya!!
Well.. I know the definition of tessellates can help us figure out the answer..
<span>A tessellation of a flat surface is the tiling of a plane using one or more geometric shapes, called tiles, with no overlaps and no gaps.</span>
<span>I know we can do this with triangles. </span>
<span>My guess would be triangles.</span>
