A scientist begins an experiment with a petri dish containing a culture of bacteria cells and records the cell growth every hour

. At 1 hour, the bacteria had grown to 880 cells, and at 2 hours, had grown to 3,520 cells. Which function can be used to represent the relationship between the number of bacteria cells, y, and the time in hours, x?
y = 4 x
y = 220(4) x
y = 880(4) x
y = 880(0.25) x

A bank loaned out $18,000, part of it at the rate of 6% per year and the rest at 16% per
ivann1987 [24]

Answer:

$6500

Step-by-step explanation

x = amount ($) loaned at 6%

then

18000-x = amount ($) loaned at 14%

.06x + .14(18000-x) = 2000

.06x + 2520-.14x = 2000

2520-.08x = 2000

-.08x = -520

x = $6,500

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the curves about the given
rewona [7]

Answer:

5.81

Step-by-step explanation:

The method of cylindrical shells uses this formula:

\int\limits^a_b {2 \pi * shellRadius * shellHeight} \, dx

It integrates the pieces of area in the region.

In this case:

2 \pi * \int\limits^2_0 {x * cos(\frac{\pi}{4} * x)} \, dx

Integrating by computer:

2*\pi*(\frac{4}{\pi^2}*(\pi*x*sin(\frac{\pi}{4}*x) + 4*cos(\frac{\pi}{4}*x)))

Evaluating between 0 and 2

2\pi * (\frac{4}{\pi^2}*(\pi*2*sin(\frac{\pi}{4}*2) + 4*cos(\frac{\pi}{4}*2)) - \frac{4}{\pi^2}*(\pi*0*sin(\frac{\pi}{4}*0) + 4*cos(\frac{\pi}{4}*0))) = 5.81
