this is about using a conveyor, then you need to sort them according to size(small, medium, large). The machine will put them in separate boxes.

Had this on a test and it completely stumped me. Since then, I've lost the math book that would give me the answer. I was hoping there'd be a math genius that'd know off hand. ^-^

Solve for x:

1. (0.04)^x+2 = 256

Note: x+2 is the exponent of 0.04.

What is x?

2007-11-20 19:57:02 · 6 answers · asked by Anonymous in Mathematics

A. Simplify:

1. (25^3/2) / (5)^-1/2


B. Solve for x:

1. (0.04)^x+2 = 256

Note: In A, 3/2 is the exponent of 25, while -1/2 is the exponent of 5. In B, x+2 is the exponent of 0.04.

Sorry everyone I have not gotten on for a few days, my son in the past 2 weeks broken his arm and now has some kind of rare syndrome involving rashes. It has been one hell of a ride plus my health isn't good lately.

We are doing logarithms, and I have no examples of problems like this, and have no idea how to do it. I believe you'd take the log of both sides....then I got nuthin. Any assistance is appreciated.

Some people seem to think that they will do severe damage to their health if they skip even one or two meals, and the conventional wisdom seems to be that skipping meals is a bad idea, and that a complete zero-calorie fast is life-threatening, even if it's only for a few days. However, I have been searching articles in the so-called "prestigious peer-reviewed medical journals," and I find almost no cases of any bad effects of fasting lasting up to 30 days and even longer. Does anybody know of any real evidence (or personal experiences) of any harm done by total fasts of up to 30 days? Please be specific.

We send probes on basically a universal plane. Basically, exploring the universe on a horizontal axis. Why not vertically? is it possible? Or does the universe reside on a plane that can only be explored horizontally?

A square measuring 5" × 5" has a surface area of 50 in²

Doesnt each square have a front side and a reverse side?

If I asked to measure the surface area of a cube, arent all sides considered?

Imagine a hollow, open-ended cylinder. The surface area would be both internal and external... plus the areas of the ends - the donut shapes, connecting internal and external... not the hollow center. Why is it this is a consistent rule for cylinders of this design... but when we take the limit of the surface area as the the width of the donut gets smaller, the area is relatively constant. But when the width reaches zero, the ares is suddenly cut in half for only arbitrary reasons - that being the cylinder is now a two dimensional object curving in on itself in three dimensional space

4(2cosx + 1) = 0
therefore:
2cosx = -1
cosx = -1/2

(2nd and 3rd quadrants bcoz its negative)

x = 120
and 180 + 60 = 240

x = 120, 240

I mean, if one fell over it would be crushed by its own weight. How could a creature that heavy exist?
