The easiest way to find such limits, where there is a numerator and a denominator is to apply <span><span>Hospital's Rule.
1st find the derivative of the numerator and the derivative of the denominator, if it still gives an indeterminate value, find the second derivative of N and D

3) lim sin(2x)/x when x →0
 Derivative sin2x → 2cos2x
 Derivative x→ 1
 2cos2x/1 when x→0 , 2cos2x → 2
 and lim sin(2x)/x when x →0 is 2

4) lim(sinx)/(2x²-x)

→cosx/(2x-1) when x →0 cosx/(2x-1) = -1
and lim(sinx)/(2x²-x) when x →0 is -1

and so on and so forth. Try to continue following the same principle

KATRIN_1 [288]
Answer: B (130)
Explanation:
A trapezoidal Riemann sum can be found by multiplying the width (the change in x) of each sub interval by the average of the y values of the two points at either end of the section and then adding up all of the sun intervals. Therefore, the trapezoidal approximation would equal 0.5(40) + 1.5(50) + 1(35) to get the answer of 130.

stira [4]

The principle which allowed Marta to find her dog Roxy is known as an: d. absolute threshold.

<h3>What is an absolute threshold?</h3>

An absolute threshold can be defined as the smallest (lowest) level of stimulus such as light, touch, sound, etc., that can be detected by a living organism, usually half the time.

In this scenario, a principle which allowed Marta to find her dog Roxy amid all of the other barking dogs is known as an absolute threshold.
