(a) Find the Riemann sum for f(x) = 4 sin(x), 0 ≤ x ≤ 3π/2, with six terms, taking the sample points to be right endpoints. (Rou

miskamm [114]

Split up the integration interval into 6 subintervals:

$\left[0,\dfrac\pi4\right],\left[\dfrac\pi4,\dfrac\pi2\right],\ldots,\left[\dfrac{5\pi}4,\dfrac{3\pi}2\right]$

where the right endpoints are given by

$r_i=i\dfrac{\frac{3\pi}2-0}6=\dfrac{i\pi}4$

for $1\le i\le6$ . Then we approximate the integral

$\displaystyle\int_0^{3\pi/2}4\sin x\,\mathrm dx$

by the Riemann sum,

$\displaystyle\sum_{i=1}^6f(r_i)\frac{\frac{3\pi}2-0}6=\pi\sum_{i=1}^6\sin\frac{i\pi}4$

$=\pi\left(\dfrac1{\sqrt2}+1+\dfrac1{\sqrt2}+0-\dfrac1{\sqrt2}-1\right)=\dfrac\pi{\sqrt2}\approx\boxed{2.221441}$

Compare to the actual value of the integral, which is exactly 4.

So confused need help. If u have a easy way to solve please help

ycow [4]

Answer: X= 6-4^z/2

Step-by-step explanation: first you need to get rid of the 4. You subtract it from both sides. So now

2x=6-4 to the power of z

So now you need to get rid of the 2. You divide both sides by two. Then you get

X= 6-4^z/2

As a block of ice melts it changes from 1 3/4 lb to 1/4 lb and takes 1/4 hr. What is the rate the ice changes?

Nutka1998 [239]

The rate at which the ice changes is -3/8 lb per hr

<h3>What is the rate the ice changes?</h3>

The given parameters are:

Changes =1 3/4 lb to 1/4 lb

Time = 1/4 hr.

The rate the ice changes is calculated as:

Rate = Change/Time

So, we have

Rate = (1/4 lb - 1 3/4 lb)/(1/4 hr)

Evaluate the difference

Rate = (-1 1/2 lb)/(1/4 hr)

Evaluate the quotient

Rate = -3/8 lb per hr

Hence, the rate at which the ice changes is -3/8 lb per hr
