Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A = × 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
Answer:
C.<em> </em><em>The quotient of the natural logarithm of 2 and e.</em>
Step-by-step explanation:
The position of a particle on the x-axis at time t, t > 0, is given by
with t is in seconds and s(t) is in feet.
The rate of change is,
=
So rate of change of position or average velocity, for e ≤ t ≤ 2e will be,
Therefore, option C is the correct answer.
