Use the fundamental theorem of calculus to evaluate the following definite integral. Integral from 3 to 4 (2 x squared plus 9 )d

oksian1 [2.3K]

Answer:

Theorem of calculus

Step-by-step explanation:

Take the integral

$\int\limits^3_4 (2x^2+9)dx$

Integrate the sum term by term and factor out constants

$= 2 \int\limits^4_3 x^2 dx + 9 \int\limits^4_3 1 dx$

Apply the fundamental theorem of calculus.

<em>The antiderivative of x^2 is x^3/3, while for a constat is x</em>

$= \frac{2x^3}{3} + 9x dx$

Evaluate the limits

$= (2*\frac{(4)^3}{3}+9*4)-(2*\frac{(3)^3}{3}+9*3)$

$=\frac{101}{3}$

Find the sum of the geometric series.

sveticcg [70]

Answer:

40/3 option B

Step-by-step explanation:

20-10+5-5/2+ ...

We need to find the sum of infinite geometric series

$S_n = \frac{a}{1-r}$

a is the first term (20)

r is the common ratio

To find common ratio we divide second term by first term

r= $\frac{-10}{20} = -\frac{1}{2}$

now we plug in the values

$S_n = \frac{20}{1-(-\frac{1}{2}}$

$S_n = \frac{20}{1+\frac{1}{2}}$

$S_n = \frac{20}{\frac{3}{2}}$

$S_n = 20 * \frac{2}{3}$

sum = 40/3

Answer:

0.1219512195122

Step-by-step explanation:

To write 10/82 as a decimal you have to divide numerator by the denominator of the fraction.

We divide now 10 by 82 what we write down as 10/82 and we get 0.1219512195122
