AB = 29

We can split the line into two parts and then we see the distance from -8 to 0 equals 8 (in mathematical language |-8| = 8). The distance from 0 to 21 is obviously 21. Therefore the total length equals the sum of the numbers above and is 21 + 8 = 29.

Determine whether the improper integral converges or diverges, and find the value of each that converges.
shusha [124]

Answer:convergent

Step-by-step explanation:

Given

Improper Integral I is given as

I=\int_{-\infty}^{0}1000e^xdx

I=1000=\int_{-\infty}^{0}e^xdx

integration of e^x is e^x

I=1000\times \left [ e^x\right ]^{0}_{-\infty}

I=1000\times I=\left [ e^0-e^{-\infty}\right ]

I=1000\times \left [ e^0-\frac{1}{e^{\infty}}\right ]

I=1000\times 1=1000

so the integration converges to 1000 units

Converting mixed numbers to impoper fractions
Oduvanchick [21]
To convert a mixed number to an improper, first, multiply the denominator of the fraction and the whole number of the fraction. Then, add the numerator to the product of the denominator and the whole number.
For example, 3 1/4. Multiply the 3 and 4 to get 12. Then add the one and you get 13. Lastly, take your sum (13 in this case) and put it over the original denominator (4) Your answer is 13/4. Hope that helps :)
