bulgar [2K]
The rate of increase is
\frac{15025}{12089}\approx1.242865

The percent of increase is then
(1.242865-1)*100\%=0.242865*100\%=24.2865\%

A concrete block has a cy
geniusboy [140]
To solve this problem, we will subtract the volume of the cylinder from the volume of the rectangular prism.

The volume of a cylinder is: pi*r^2*h
Substitute 2 in for r and 6 in for h. If the diameter is 4, then the radius is 2.
pi*2^2*6
pi*4*6
pi*24
=75.4 ft^2

The volume of the rectangular prism is: l*w*h.
Substitute 6 in for l, w and h, since all edges are equal.
6*6*6
36*6
=216 ft^2

Subtract 75.4 from 216
216-75.4=140.6

There is 140.6 cubic feet of concrete left in the block.

Determine whether each of these functions is O(x^2 ).
otez555 [7]

Answer:

  • (a)  no
  • (b)  yes
  • (c)  no
  • (d)  no

Step-by-step explanation:

"Of the order x^2" means the dominant behavior matches that of x^2 as x gets large. For polynomial functions, the dominant behavior is that of the highest-degree term.

For other functions, the dominant behavior will typically be governed in some other way. Here, the rate of growth of the x·log(x) function is determined by log(x), which has decreasing slope as x increases.

Only answer selection B has a highest-degree term of x^2, so only that one exhibits O(x^2) behavior.
