Use the Midpoint Rule with n = 5 to estimate the volume V obtained by rotating about the y-axis the region under the curve y = 1
velikii [3]

Using the shell method, the volume is given exactly by the definite integral,

2\pi\displaystyle\int_0^1x(1+9x^3)\,\mathrm dx

Splitting up the interval [0, 1] into 5 subintervals gives the partition,

[0, 1/5], [1/5, 2/5], [2/5, 3/5], [3/5, 4/5], [4/5, 5]

with left and right endpoints, respectively, for the i-th subinterval

\ell_i=\dfrac{i-1}5

r_i=\dfrac i5

where 1\le i\le5. The midpoint of each subinterval is

m_i=\dfrac{\ell_i+r_i}2=\dfrac{2i-1}{10}

Then the Riemann sum approximating the integral above is

2\pi\displaystyle\sum_{i=1}^5m_i(1+9{m_i}^3)\frac{1-0}5

\dfrac{2\pi}5\displaystyle\sum_{i=1}^5\left(\frac{2i-1}{10}+9\left(\frac{2i-1}{10}\right)^4\right)

\dfrac{2\pi}{5\cdot10^4}\displaystyle\sum_{i=1}^5\left(16i^4-32i^3+24i^2+1992i-999\right)=\frac{112,021\pi}{25,000}\approx\boxed{14.08}

(compare to the actual value of the integral of about 14.45)

What are the roots of this equation 2x^2+7x-3=0
Ludmilka [50]

Step-by-step explanation:

2x^2+7x-3=0

by doing splitting the middle term we get/ <u>using quadratic eq we get-</u>

Let's solve your equation step-by-step.

2x2+7x−3=0

For this equation: a=2, b=7, c=-3

2x2+7x+−3=0

Step 1: Use quadratic formula with a=2, b=7, c=-3.

x=

−b±√b2−4ac

2a

x=

−(7)±√(7)2−4(2)(−3)

2(2)

x= −7±√73 /4

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73

Answer:

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73
