<h3>
Answer:</h3>
34 mph
Step-by-step explanation:
Average speed = total distance / total time
Total distance = ( 40 × 2 + 30 × 3 )
= 170 miles
Total time = 5 h
So, avg speed = 170/5 = 34 mph
I have attached the answer. Enjoy!
The surface area of a rectangular prism is given by
... S = 2(LW +H(L+W))
For your dimensions, the surface area is
... S = 2(3·1 + 2(3+1)) = 2(3 + 8) = 22 . . . ft²
The derivatives of sin(<em>x</em>) follow a simple pattern:
<em>f(x)</em> = sin(<em>x</em>)
<em>f '(x)</em> = cos(<em>x</em>)
<em>f ''(x)</em> = - sin(<em>x</em>)
<em>f '''(x)</em> = - cos(<em>x</em>)
<em>f ''''(x)</em> = sin(<em>x</em>)
and so on. 96 is a multiple of 4, so
<em>f</em> ⁽⁹⁶⁾<em>(x)</em> = sin(<em>x</em>)
