The time taken by the acorn to fall 1.16 seconds
I believe it would be 70° because angle ABD is 70° and they should be alternate exterior angles

Set

, so that

. Then the integral is

Or, if you meant exponents in place of coefficients,

Let

, so that

, and use the fact that

to get

Bearing in mind that a rectangle has a perimeter of length + length + width + width.
P = perimeter
L = length
x=width
P = 2L + 2x
P = 2(L+x) <==== perimeter of the base of the box.
check the picture below.
Answer:Using the slope-intercept form, the y-intercept is 1
