This one is just common sense - you don't even have to do any work. Since there's a negative on both the top and bottom you cancel them, which eliminates both the second and third answer choices. Also, 8/10 and 4/5 are the same, but 4/5 is simplified more so that is your answer.
Answer:
1.0, 1.09, 1.1, 1.19, 1.9
Step-by-step explanation:
Basic ordering of decimals
4b^-6
When u have a negative exponent, u simply take the reciprocal. So the answer is
4/b^6
Answer:
Step-by-step explanation:
1a. -3 * -4 = 4 * 3
b.7(4+11) = 7(4) + 7(11)
c.6(7-4) = 6(3) - (0) *4
d. -2(6*(-5)) = -2*6*(-5)
2a.-60+4 = -56 = 50
b.-20 / 3 = 6.6 = 6.0 = 6
c. 2.4 = 2.0 = 2
d. 47.19 =40.00 = 40
e. 35.624+ (-4.17) = 31.454 =30.000 = 30
I assume the base of S is the disk centered at the origin, or x² + y² ≤ r². Solving for y gives two solutions corresponding to the upper and lower halves of the circular boundary,
and the vertical distance between them - i.e. the side length of each cross section - is
Then the volume of each square cross section 4 (r² - x²) ∆x, and the volume of S is
By symmetry, this is the same as
which gives a volume of
