Answer:
Step-by-step explanation:
In this cross sections problem, we can integrate from -r to +r (so that the integral covers the entire base of the solid).
The formatting for the integral did not let me put -r on the lower bound, so i replaced it with a, just know that a represents -r here.
Evaluating the integral gives use that it is equal to;

For <u> the following subtraction problems 17t 13lb 3oz - 9t 20lb 9oz the output is oz = 7 T 1992 lb 12 oz</u>
Step-by-step explanation:
Let us first consider that
<u>1 T = 2,000 lb</u>
<u>1 lb = 16 oz</u>
Here we will convert all the measure units to oz, subtracted the amounts, and finally converted the units back to their original ones.
<u>17t 13lb 3oz - 9t 20lb 9oz (The equation given to us)</u>
<u>It can be rewritten as </u>
=17 T or (2,000 lb*17) + 13 lb + 3 oz) - (9 T or (2,000 lb*9) + 20 lb + 9 oz)
= (34,013 lb or (16 oz *34,013) + 3 oz) - (18,020 lb or (16 oz *18,020) + 9 oz)
= 544,213 oz - 288,329 oz = 255,884
<u>oz = 7 T 1992 lb 12 oz</u>
2,983,600 is your answer to the nearest hundred
For the first one, find a number in which, when factored, will give you 4.
x² + 4x + 4
x 2
x 2
(x + 2)(x+ 2)
4 is your best answer
2. x² - 10x + ____
Same for this question. Find a number that, when factored, will give you -10
-100
x² - 10x + 25
x - 5
x -5
(x - 5)(x - 5)
25 is your answer
hope this helps
